FAQ
Q:Key points of selection of planetary reducer
A:1. Frame number determined by torque: the power source will have the effect of torque amplification after deceleration ratio. The output torque value of the reducer is proportional to the deceleration ratio, and the larger the ratio, the higher the torque value will be; But the gear group of the reducer has the limit, so the rated output torque of the planetary reducer is to say that the product can work stably under the data operation, so the box number must be selected according to the demand torque.
2. According to the accuracy to determine the model: in the process of automation will need positioning, when the positioning accuracy requirements are higher, you need to choose a higher level of products, and vice versa. The precision of the planetary reducer is called the “backgap”, which refers to the gap of the gear group. The definition is the Angle value that the output shaft of the planetary reducer can rotate when the input end is fixed. The smaller the return clearance is, the higher the accuracy is and the higher the cost is. The user can choose the right accuracy according to their actual situation.
3. According to the installation size selection: that is, the size of the front end of the servo motor. The input end of the planetary reducer must match the output end of the servo motor.
4. According to the appearance selection: according to customer demand output shaft and connecting surface has a standard series for users to choose, can also be customized according to user special needs.
5. According to the axial and radial force selection: the life of the planetary reducer is affected by the internal bearing, bearing life can be calculated through the load and speed, when the axial and radial force load of the reducer is higher, the bearing life will be shortened, at this time it is recommended to choose a large product.

The Cyclonoidal Gearbox
Basically, the cycloidal gearbox is a gearbox that uses a cycloidal motion to perform its rotational movement. It is a very simple and efficient design that can be used in a variety of applications. A cycloidal gearbox is often used in applications that require the movement of heavy loads. It has several advantages over the planetary gearbox, including its ability to be able to handle higher loads and higher speeds.
Dynamic and inertial effects of a cycloidal gearbox
Several studies have been conducted on the dynamic and inertial effects of a cycloidal gearbox. Some of them focus on operating principles, while others focus on the mathematical model of the gearbox. This paper examines the mathematical model of a cycloidal gearbox, and compares its performance with the real-world measurements. It is important to have a proper mathematical model to design and control a cycloidal gearbox. A cycloidal gearbox is a two-stage gearbox with a cycloid disc and a ring gear that revolves around its own axis.
The mathematical model is made up of more than 1.6 million elements. Each gear pair is represented by a reduced model with 500 eigenmodes. The eigenfrequency for the spur gear is 70 kHz. The modally reduced model is a good fit for the cycloidal gearbox.
The mathematical model is validated using ABAQUS software. A cycloid disc was discretized to produce a very fine model. It requires 400 element points per tooth. It was also verified using static FEA. This model was then used to model the stiction of the gears in all quadrants. This is a new approach to modelling stiction in a cycloidal gearbox. It has been shown to produce results comparable to those of the EMBS model. The results are also matched by the elastic multibody simulation model. This is a good fit for the contact forces and magnitude of the cycloid gear disc. It was also found that the transmission accuracy between the cycloid gear disc and the ring gear is about 98.5%. However, this value is lower than the transmission accuracy of the ring gear pair. The transmission error of the corrected model is about 0.3%. The transmission accuracy is less because of the lower amount of elastic deformation on the tooth flanks.
It is important to note that the most accurate contact forces for each tooth of a cycloid gearbox are not smooth. The contact force on a single tooth starts with a linear rise and then ends with a sharp drop. It is not as smooth as the contact force on a point contact, which is why it has been compared to the contact force on an ellipse contact. However, the contact on an ellipse contact is still relatively small, and the EMBS model is not able to capture this.
The FE model for the cycloid disc is about 1.6 million elements. The most important part of the FE model is the discretization of the cycloid disc. It is very important to do the discretization of the cycloid gear disc very carefully because of the high degree of vibration that it experiences. The cycloid disc has to be discretized finely so that the results are comparable to those of a static FEA. It has to be the most accurate model possible in order to be able to accurately simulate the contact forces between the cycloid disc and the ring gear.
Kinematics of a cycloidal drive
Using an arbitrary coordinate system, we can observe the motion of components in a cycloidal gearbox. We observe that the cycloidal disc rotates around fixed pins in a circle, while the follower shaft rotates around the eccentric cam. In addition, we see that the input shaft is mounted eccentrically to the rolling-element bearing.
We also observe that the cycloidal disc rotates independently around the eccentric bearing, while the follower shaft rotates around an axis of symmetry. We can conclude that the cycloidal disc plays a pivotal role in the kinematics of a cycloidal gearbox.
To calculate the efficiency of the cycloidal reducer, we use a model that is based on the non-linear stiffness of the contacts. In this model, the non-linearity of the contact is governed by the non-linearity of the force and the deformation in the contact. We have shown that the efficiency of the cycloidal reducer increases as the load increases. In addition, the efficiency is dependent on the sliding velocity and the deformations of the normal load. These factors are considered as the key variables to determine the efficiency of the cycloidal drive.
We also consider the efficiency of the cycloidal reducer with the input torque and the input speed. We can calculate the efficiency by dividing the net torque in the ring gear by the output torque. The efficiency can be adjusted to suit different operating conditions. The efficiency of the cycloidal drive is increased as the load increases.
The cycloidal gearbox is a multi-stage gearbox with a small shaft oin and a big shaft. It has 19 teeth and brass washers. The outer discs move in opposition to the middle disc, and are offset by 180 deg. The middle disc is twice as massive as the outer disc. The cycloidal disc has nine lobes that move by one lobe per drive shaft revolution. The number of pins in the disc should be smaller than the number of pins in the surrounding pins.
The input shaft drives an eccentric bearing that is able to transmit the power to the output shaft. In addition, the input shaft applies forces to the cycloidal disk through the intermediate bearing. The cycloidal disk then advances in 360 deg/pivot/roller steps. The output shaft pins then move around in the holes to make the output shaft rotate continuously. The input shaft applies a sinusoidal motion to maintain the constant speed of the base shaft. This sine wave causes small adjustments to the follower shaft. The forces applied to the internal sleeves are a part of the equilibrium mechanism.
In addition, we can observe that the cycloidal drive is capable of transmitting a greater torque than the planetary gear. This is due to the cycloidal gear’s larger axial length and the ring gear’s smaller hole diameter. It is also possible to achieve a positive fit between the fixed ring and the disc, which is achieved by toothing between the fixed ring and the disc. The cycloidal disk is usually designed with a short cycloid to minimize unbalance forces at high speeds.
Comparison with planetary gearboxes
Compared to planetary gearboxes, the cycloidal gearbox has some advantages. These advantages include: low backlash, better overload capacity, a compact design, and the ability to perform in a wide range of applications. The cycloidal gearbox has become popular in the multi-axis robotics market. The gearbox is also increasingly used in first joints and positioners.
A cycloidal gearbox is a gearbox that consists of four basic components: a cycloid disk, an output flange, a ring gear, and a fixed ring. The cycloid disk is driven by an eccentric shaft, which advances in a 360deg/pivot/roller step. The output flange is a fixed pin disc that transmits the power to the output shaft. The ring gear is a fixed ring, and the input shaft is connected to a servomotor.
The cycloidal gearbox is designed to control inertia in highly dynamic situations. These gearboxes are generally used in robotics and positioners, where they are used to position heavy loads. They are also commonly used in a wide range of industrial applications. They have higher torque density and a low backlash, making them ideal for heavy loads.
The output flange is also designed to handle a torque of up to 500 Nm. Its rotational speed is lower than the planet gearbox, but its output torque is much higher. It is designed to be a high-performance gearbox, and it can be used in applications that need high ratios and a high level of torque density. The cycloid gearbox is also less expensive and has less backlash. However, the cycloidal gearbox has disadvantages that should be considered when designing a gearbox. The main problem is vibrations.
Compared to planetary gearboxes, cycloidal gearboxes have a smaller overall size and are less expensive. In addition, the cycloid gearbox has a large reduction ratio in one stage. In general, cycloidal gearboxes have single or two stages, with the third stage being less common. However, the cycloid gearbox is not the only type of gearbox that has this type of configuration. It is also common to find a planetary gearbox with a single stage.
There are several different types of cycloidal gearboxes, and they are often referred to as cycloidal speed reducers. These gearboxes are designed for any industry that uses servos. They are shorter than planetary gearboxes, and they are larger in diameter for the same torque. Some of them are also available with a ratio lower than 30:1.
The cycloid gearbox can be a good choice for applications where there are high rotational speeds and high torque requirements. These gearboxes are also more compact than planetary gearboxes, and are suitable for high-torque applications. In addition, they are more robust and can handle shock loads. They also have low backlash, and a higher level of accuracy and positioning accuracy. They are also used in a wide range of applications, including industrial robotics.

A Mathematical Model of a Cycloid Gearbox
Having a gearbox with a cycloidal rotor is an ideal design for a car or any other vehicle, as the cycloidal design can reduce the amplitude of vibration, which is a key component in car performance. Using a cycloidal gearbox is also a great way to reduce the amount of friction between the gears in the gearbox, which can help to reduce noise and wear and tear. A cycloidal gearbox is also a very efficient design for a vehicle that needs to perform under high loads, as the gearbox can be very robust against shock loads.
Basic design principles
cycloidal gearboxes are used for precision gearing applications. Cycloidal drives are compact and robust and offer lower backlash, torsional stiffness and a longer service life. They are also suitable for applications involving heavy loads.
Cycloidal drives are compact in size and provide very high reduction ratios. They are also very robust and can handle shock loads. Cycloidal drives are ideally suited to a wide range of drive technologies. Cycloidal gears have excellent torsional stiffness and can provide a transmission ratio of 300:1. They can also be used in applications where stacking multiple gear stages is not desired.
In order to achieve a high reduction ratio, cycloidal gears must be manufactured extremely accurately. Cycloidal gears have a curved tooth profile that removes shear forces at any point of contact. This provides a positive fit for the gear disc. This profile can be provided on a separate outer bushing or as an internal gear profile insert.
Cycloidal drives are used in marine propulsion systems, where the load plate rotates around the X and Y axis. The plate is anchored by a threaded screw hole arranged 15mm away from the center.
A secondary carrier body is used in a cycloidal gearbox to support the load plate. The secondary carrier body is composed of a mounting carrier body and a secondary carrier disc.
Low friction
Several studies have been conducted to understand the static problems of gears. In this paper, we discuss a mathematical model of a low friction cycloidal gearbox. This model is designed to calculate various parameters that affect the performance of the gearbox during production.
The model is based on a new approach that includes the stiction effect and the nonlinear friction characteristic. These parameters are not covered by the conventional rule of thumb.
The stiction effect is present when the speed direction is changed. During this time, the input torque is required to prevail over the stiction effect to generate movement. The model also enables us to calculate the magnitude of the stiction effect and its breakaway speed.
The most important thing is that the model can be used to improve the dynamic behavior of a controlled system. In this regard, the model has a high degree of accuracy. The model is tested in several quadrants of the gearbox to find the optimum stiction breakaway speed. The simulation results of the model show that this model is effective in predicting the efficiency of a low friction cycloidal gearbox.
In addition to the stiction model, we also studied the efficiency of a low friction cycloidal reducer. The reduction ratio of this gearbox was estimated from the formula. It is found that the ratio approaches negative infinity when the motor torque is close to zero Nm.
Compact
Unlike standard planetary gears, cycloidal gearboxes are compact, low friction and feature virtually zero backlash. They also offer high reduction ratios, high load capacity and high efficiency. These features make them a viable option for a variety of applications.
Cycloid disks are driven by an eccentric input shaft. They are then driven by a stationary ring gear. The ring gear rotates the cycloidal disk at a higher rate. The input shaft rotates nine times to complete a full rotation. The ring gear is designed to correct the dynamic imbalance.
CZPT cycloidal gearheads are designed for precision and stable operation. These reducers are robust and can handle large translocations. They also offer high overload protection. They are suitable for shock wave therapy. CZPT gearheads are also well suited for applications with critical positioning accuracy. They also require low assembly and design costs. They are designed for long service life and low hysteresis loss.
CZPT cycloidal reducers are used in a variety of industrial applications, including CNC machining centers, robot positioners and manipulators. They offer a unique design that can handle high forces on the output axis, and are especially suitable for large translocations. These gearheads are highly efficient, reducing costs, and are available in a variety of sizes. They are ideal for applications that require millimetre accuracy.
High reduction ratios
Compared to other gearboxes, cycloidal gearboxes offer high reduction ratios and small backlash. They are also less expensive. Cycloid gearboxes can be used in a variety of industries. They are suitable for robotic applications. They also have high efficiency and load capacity.
A cycloidal gearbox works by rotating a cycloidal disc. This disc contains holes that are bigger than the pins on the output shaft. When the disc is rotated, the output pins move in the holes to generate a steady output shaft rotation. This type of gearbox does not require stacking stages.
Cycloid gearboxes are usually shorter than planetary gearboxes. Moreover, they are more robust and can transmit higher torques.
Cycloid gearboxes have an eccentric cam that drives the cycloidal disc. The cycloidal disc advances in 360deg/pivot/roller steps. It also rotates in an eccentric pattern. It meshes with the ring-gear housing. It also engages the internal teeth of the ring-gear housing.
The number of lobes on the cycloidal disc is not sufficient to generate a good transmission ratio. In fact, the number of lobes must be less than the number of pins surrounding the cycloidal disc.
The cycloidal disc is rotated by an eccentric cam that extends from the base shaft. The cam also spins inside the cycloidal disc. The eccentric motion of the cam helps the cycloidal disc rotate around the pins of the ring-gear housing.
Reducing amplitude of the vibration
Various approaches to reducing amplitude of the vibration in a cycloidal gearbox have been studied. These approaches are based on the kinematic analysis of gearbox.
A cycloidal gearbox is a gearbox that consists of bearings, gears, and an eccentric bearing that drives a cycloidal disc. This gearbox has a high reduction ratio, which is achieved by a series of output shaft pins that drive the output shaft as the disc rotates.
The test bench used in the studies has four sensors. Each sensor acquires signals with different signal processing techniques. In addition, there is a tachometer that acquires variations in rotational velocity at the input side.
The kinematic study of the robotic gearbox was performed to understand the frequency of vibrations and to determine whether the gearbox is faulty. It was found that the gearbox is in healthy operation when the amplitude of the x and y is low. However, when the amplitude is high, it is indicative of a malfunctioning element.
The frequency analysis of vibration signals is performed for both cyclostationary and noncyclostationary conditions. The frequencies that are selected are those that appear in both types of conditions.
Robust against shock loads
Compared to traditional gearboxes, cycloidal gearboxes have significant benefits when it comes to shock loads. These include high shock-load capacity, high efficiency, reduced cost, lower weight, lower friction, and better positioning accuracy.
Cycloid gears can be used to replace traditional planetary gears in applications where inertia is important, such as the transportation of heavy loads. They have a lighter design and can be manufactured to a more compact size, which helps reduce cost and installation expense. Cycloid gears are also able to provide transmission ratios of up to 300:1 in a small package.
Cycloid gears are also suitable for applications where a long service life is essential. Their radial clamping ring reduces inertia by up to 39%. Cycloid gears have a torsional stiffness that is five times higher than that of conventional planetary gears.
Cycloid gearboxes can provide significant improvements in concrete mixers. They are a highly efficient design, which allows for important innovations. They are also ideal for servo applications, machine tools, and medical technology. They feature user-friendly screw connections, effective corrosion protection, and effective handling.
Cycloid gears are especially useful for applications with critical positioning accuracy. For example, in the control of large parabolic antennas, high shock load capacity is required to maintain accuracy. Cycloid gears can withstand shock loads up to 500% of their rated torque.
Inertial effects
Various studies have been conducted to investigate the static problems of gears. However, there is still a need for a proper model to investigate the dynamic behaviour of a controlled system. For this, a mathematical model of a cycloidal gearbox has been developed. The presented model is a simple model that can be used as the basis for a more complex mechanical model.
The mathematical model is based on the cycloidal gearbox’s mechanical construction and has a nonlinear friction characteristic. The model is able to reproduce the current peaks and breaks at standstill. It also considers the stiction effect. However, it does not cover backlash or torsional stiffness.
This model is used to calculate the torque generating current and the inertia of the motor. These values are then compared with the real system measurement. The results show that the simulation results are very close to the real system measurement.
Several parameters are considered in the model to improve its dynamic behaviour. These parameters are calculated from the harmonic drive system analysis. These are torque-generating current, inertia, and the contact forces of the rotating parts.
The model has a high level of accuracy and can be used for motor control. It is also able to reproduce the dynamic behaviour of a controlled system.

Efficiency of Cycloidal Gearboxes in Power Transmission
Cycloidal gearboxes offer relatively high power transmission efficiency compared to other types of gearboxes. The efficiency of a cycloidal gearbox depends on various factors, including the design, quality of components, lubrication, and load conditions.
Typically, the power transmission efficiency of a cycloidal gearbox ranges from 85% to 95%. However, this can vary based on several factors:
- Number of Reduction Stages: Multi-stage cycloidal gearboxes may experience slightly lower efficiency due to multiple gear meshing interactions.
- Quality and Design: Well-designed and precision-manufactured cycloidal gearboxes tend to exhibit higher efficiency.
- Lubrication: Proper lubrication is crucial for reducing friction and enhancing efficiency. Insufficient or deteriorated lubrication can lead to efficiency losses.
- Load Conditions: Higher loads and torque levels can lead to higher friction and lower efficiency. Properly matching the gearbox to the application is essential.
Despite minor efficiency losses compared to some other gearbox types, the benefits of compactness, high torque density, and precise motion control often outweigh the efficiency considerations in many applications.
Use of Cycloidal Gearboxes in Precision Applications
Cycloidal gearboxes are well-suited for precision applications due to their unique design and capabilities. Here’s why they are used in precision settings:
- High Positional Accuracy: Cycloidal gearboxes offer high positional accuracy, making them suitable for applications that require precise positioning and movement.
- Backlash Reduction: The design of cycloidal gearboxes minimizes backlash, ensuring that there is minimal play between gears. This is crucial for maintaining accuracy in precision applications.
- Smooth and Controlled Motion: Cycloidal gearboxes provide smooth and controlled motion with minimal vibration, which is essential for delicate operations and precision machinery.
- Compact Design: Their compact design allows cycloidal gearboxes to be integrated into tight spaces without sacrificing performance. This is especially valuable in applications where space is limited.
- Repeatable Performance: Cycloidal gearboxes offer consistent and repeatable performance, which is vital for maintaining precision over multiple cycles.
- Low Backlash: The low backlash characteristic of cycloidal gearboxes ensures that there is minimal lost motion, contributing to their precision performance.
- High Torque Density: Despite their compact size, cycloidal gearboxes can handle high torque loads, making them suitable for applications that require both precision and power.
- Reduced Wear: The rolling contact design of cycloidal gears reduces wear and extends the lifespan of the gearbox, which is crucial for precision applications that demand consistent performance over time.

The Basics of a Cyclone Gearbox
Besides being compact, cycloidal speed reducers also offer low backlash and high ratios. Because of the small size of the drive, they are ideal for applications where space is a problem.
Involute gear tooth profile
Almost all gears use an involute gear tooth profile. This profile has a single curve, which means that the gear teeth do not have to be aligned closely with each other. This profile is smooth and can be manufactured easily.
Cycloid gears have a combination of epicycloid and hypocycloid curves. This makes them stronger than involute gear teeth. However, they can be more expensive to manufacture. They also have larger reduction ratios. They transmit more power than involute gears. Cycloid gears can be found in clocks.
When designing a gear, you need to consider several factors. Some of these include the number of teeth, the tooth angle and the lubrication type. Having a gear tooth that is not perfectly aligned can result in transmission error, noise and vibration.
The tooth profile of an involute gear is usually considered the best. Because of this, it is used in a wide variety of gears. Some of the most common applications for this profile are power transmission gears. However, this profile is not the best for every application.
Cycloid gears require more complex manufacturing processes than involute gear teeth. This can cause a larger tooth cost. Cycloid gears are used for less noisy applications.
Cycloid gears also transmit more power than involute gears. This can cause problems if the radii change tangentially. However, the shape is more simple than involute gears. Involute gears can handle centre sifts better.
Cycloid gears are less susceptible to transmission error. Cycloid gears have a convex surface, which makes them stronger than involute teeth. Cycloid gears also have a larger reduction ratio than involute gears. Cycloid teeth do not interfere with the mating teeth. However, they have a smaller number of teeth than involute teeth.
Rotation on the inside of the reference pitch circle of the pins
Whether a cycloidal gearbox is designed for stationary or rotating applications, the fundamental law of gearing must be observed: The ratio of angular velocities must be constant. This requires the rotation on the inside of the reference pitch circle of the pins to be constant. This is achieved through a series of cycloidal teeth, which act like tiny levers to transmit motion.
A cycloidal disc has N lobes which are rotated by three lobes per rotation around N pins. The number of lobes on a cycloidal disc is a significant factor in determining the transmission ratio.
A cycloidal disc is driven by an eccentric input shaft which is mounted to an eccentric bearing within an output shaft. As the input shaft rotates, the cycloidal disc moves around the pins of the pin disc.
The drive pin rotates at a 40 deg angle while the cycloidal disc rotates on the inside of the reference pitch circle of pins. As the drive pin rotates, it will slow the output motion. This means that the output shaft will complete only three revolutions with the input shaft, as opposed to nine revolutions with the input shaft.
The number of teeth on a cycloidal disc must be small compared to the number of surrounding pins. The disc must also be constructed with an eccentric radius. This will determine the size of the hole which will be required for the pin to fit between the pins.
When the input shaft is turned, the cycloidal disc will rotate on the inside of the reference pitch circle of roller pins. This will then transmit motion to the output shaft. The output shaft is supported by two bearings in an output housing. This design has low wear and torsional stiffness.
Transmission ratio
Choosing the right transmission ratio of cycloidal gearbox isn’t always easy. You might need to know the size of your gearbox before you can make an educated choice. You may also need to refer to the product catalog for guidance. For example, CZPT gearboxes have some unique ratios.
A cycloidal gear reducer is a compact and high-speed torque transmission device that reverses the direction of angular movement of the follower shaft. It consists of an eccentric cam positioned inside a cycloidal disc. Pin rollers on the follower shaft fit into matching holes in the cycloidal disc. In the process, the pins slide around the holes, in response to wobbling motion. The cycloidal disc is also capable of engaging the internal teeth of a ring-gear housing.
A cycloidal gear reducer can be used in a wide variety of applications, including industrial automation, robotics and power transmissions on boats and cranes. A cycloidal gear reducer is ideally suited for heavy duty applications with large payloads. They require specialized manufacturing processes, and are often used in equipment with precise output and high efficiency.
The cycloidal gear reducer is a relatively simple structure, but it does require some special tools. Cycloid gear reducers are also used to transmit torque, which is one of the reasons they are so popular in automation. Using a cycloidal gear reducer is a good choice for applications that require higher efficiency and lower backlash. It is also a good choice for applications where size is a concern. Cycloid gears are also a good choice for applications where high speed and high torque are required.
The transmission ratio of cycloidal gearbox is probably the most important function of a gearbox. You need to know the size of your gearbox and the type of gears it contains in order to make the right choice.
Vibration reduction
Considering the unique dynamics of a cycloidal gearbox, vibration reduction measures are required for a smooth operation. These measures can also help with the detection of faults.
A cycloidal gearbox is a gearbox with an eccentric bearing that rotates the center of the gears. It shares torque load with five outer rollers at any given time. It can be applied in many applications. It is a relatively inexpensive asset. However, if it fails, it can have significant economic impacts.
A typical input/output gearbox consists of a ring plate and two cranks mounted on the input shaft. The ring plate rotates when the input shaft rotates. There are two bearings on the output shaft.
The ring plate is a major noise source because it is not balanced. The cycloidal gear also produces noise when it meshes with the ring plate. This noise is generated by structural resonance. Several studies have been performed to solve this problem.
However, there is not much documented work on the condition monitoring of cycloidal gearboxes. In this article, we will introduce modern techniques for vibration diagnostics.
A cycloidal gearbox with a reduced reduction ratio has higher induced stresses in the cycloidal disc. In this case, the size of the output hole is larger and more material is removed from the cycloidal disc. This increase in the disc’s stresses leads to higher vibration amplitudes.
The load distribution along the width of the gear is an important design criterion. Using different gear profiles can help to optimize the transmission of torque. The contact stress of the cycloidal disc can also be investigated.
To determine the amplitude of the noise, the frequency of the gear mesh is multiplied by the shaft rate. If the RPM is relatively stable, the frequency can be used as a measure of magnitude. However, this is only accurate at close to failure.
Comparison with planetary gearboxes
Several differences exist between cycloidal gearboxes and planetary gearboxes. They are related to gear geometry and manufacturing processes. Among them, there are:
– The output shaft of a cycloidal gearbox has a larger torque than the input shaft. The rotational speed of the output shaft is lower than the input shaft.
– The cycloid gear disc rotates at variable velocity, while the planetary gear has a fixed speed. Consequently, the cycloid disc and output flange transmission accuracy is lower than that of the planetary gears.
– The cycloidal gearbox has a larger gripping area than the planetary gear. This is an advantage of the cycloidal gearbox in that it can handle larger loads.
– The cycloid profile has a significant impact on the quality of contact meshing between the tooth surfaces. The width of the contact ellipses increases by 90%. This is a result of the elimination of undercuts of the lobes. In this way, the contact force on the cycloid disc is decreased significantly.
– The cycloid drive has lower backlash and high torsional stiffness. This allows a cycloidal drive to be more stable against shock loads. The cycloid drive is also a compact design, which is ideally suited for applications with large transmission ratios.
– The output hub of the cycloid gearbox has movable pins and rollers. These components are attached to the ring gear in the outer gearbox. The output shaft is also turned by the planet carrier. The output hub of the cycloid system is composed of two parts: the ring gear and the output flange.
– The input shaft of a cycloidal gearbox is connected to a servomotor. The input shaft is a cylindrical element that is fixed to the planet carrier.

Developing a Mathematical Model of a Cyclone Gearbox
Compared to planetary gearboxes, cycloidal gearboxes are often seen as the ideal choice for a wide range of applications. They feature compact designs that are often low friction and high reduction ratios.
Low friction
Developing a mathematical model of a cycloidal gearbox was a challenge. The model was able to show the effects of a variety of geometric parameters on contact stresses. It was able to model stiction in all quadrants. It was able to show a clear correlation between the results from simulation and real-world measurements.
The model is based on a new approach that enables modeling stiction in all quadrants of a gearbox. It is also able to display non-zero current at standstill. Combined with a good simulation algorithm, the model can be used to improve the dynamic behaviour of a controlled system.
A cycloidal gearbox is a compact actuator used for industrial automation. This type of gearbox provides high gear ratios, low wear, and good torsional stiffness. In addition, it has good shock load capacity.
The model is based on cycloidal discs that engage with pins on a stationary ring gear. The resulting friction function occurs when the rotor begins to rotate. It also occurs when the rotor reverses its rotation. The model has two curves, one for motor and one for generator mode.
The trochoidal profile on the cycloidal disc’s periphery is required for proper mating of the rotating parts. In addition, the profile should be defined accurately. This will allow an even distribution of contact forces.
The model was used to compare the relative performance of a cycloidal gearbox with that of an involute gearbox. This comparison indicates that the cycloidal gearbox can withstand more load than an involute gearbox. It is also able to last longer. It is also able to produce high gear ratios in a small space.
The model used is able to capture the exact geometry of the parts. It can also allow a better analysis of stresses.
Compact
Unlike helical gearing, compact cycloidal gearboxes can provide higher reduction ratios. They are more compact and less weighty. In addition, they provide better positioning accuracy.
Cycloid drives provide high torque and load capacity. They are also very efficient and robust. They are ideal for applications with heavy loads or shock loads. They also feature low backlash and high torsional stiffness. Cycloid gearboxes are available in a variety of designs.
Cycloid discs are mounted on an eccentric input shaft, which drives them around a stationary ring gear. The ring gear consists of many pins, and the cycloidal disc moves one lobe for every rotation of the input shaft. The output shaft contains roller pins, which rotate around holes in the cycloidal disc.
Cycloid drives are ideally suited to heavy loads and shock loads. They have high torsional stiffness and high reduction ratios, making them very efficient. Cycloid gearboxes have low backlash and high torque and are very compact.
Cycloid gearboxes are used for a wide variety of applications, including marine propulsion systems, CNC machining centers, medical technology, and manipulation robots. They are especially useful in applications with critical positioning accuracy, such as surgical positioning systems. Cycloid gearboxes feature extremely low hysteresis loss and low backlash over extended periods of use.
Cycloid discs are usually designed with a reduced cycloid diameter to minimize unbalance forces at high speeds. Cycloid drives also feature minimal backlash, a high reduction ratio, and excellent positioning accuracy. Cycloid gearboxes also have a long service life, compared to other gear drives. Cycloid drives are highly robust, and offer higher reduction ratios than helical gear drives.
Cycloid gearboxes have a low cost and are easy to print. CZPT gearboxes are available in a wide range of sizes and can produce high torque on the output axis.
High reduction ratio
Among the types of gearboxes available, a high reduction ratio cycloidal gearbox is a popular choice in the automation field. This gearbox is used in applications requiring precise output and high efficiency.
Cycloid gears can provide high torque and transmit it well. They have low friction and a small backlash. They are widely used in robotic joints. However, they require special tools to manufacture. Some have even been 3D printed.
A cycloidal gearbox is typically a three-stage structure that includes an input hub, an output hub, and two cycloidal gears that rotate around each other. The input hub mounts movable pins and rollers, while the output hub mounts a stationary ring gear.
The input shaft is driven by an eccentric bearing. The disc is then pushed against the ring gear, which causes it to rotate around the bearing. As the disc rotates, the pins on the ring gear drive the pins on the output shaft.
The input shaft rotates a maximum of nine revolutions, while the output shaft rotates three revolutions. This means that the input shaft has to rotate over eleven million times before the output shaft is able to rotate. The output shaft also rotates in the opposite direction of the input shaft.
In a two-stage differential cycloidal speed reducer, the input shaft uses a crank shaft design. The crank shaft connects the first and second cycloidal gears and actuates them simultaneously.
The first stage is a cycloidal disc, which is a gear tooth profile. It has n=7 lobes on its circumference. Each lobe moves around a reference pitch circle of pins. The disc then advances in 360deg steps.
The second stage is a cycloidal disc, also known as a “grinder gear”. The teeth on the outer gear are fewer than the teeth on the inner gear. This allows the gear to be geardown based on the number of teeth.

Various scholars have studied the kinematics of cycloidal gearbox. They have developed various approaches to modify the tooth profile of cycloidal gears. Some of these approaches involve changing the shape of the cycloidal disc, and changing the grinding wheel center position.
This paper describes a new approach to cycloid gear profile modification. It is based on a mathematical model and incorporates several important parameters such as pressure angle, backlash, and root clearance. The study offers a new way for modification design of cycloid gears in precision reducers for robots.
The pressure angle of a tooth profile is an intersegment angle between the normal direction and the velocity direction at a meshing point. The pressure angle distribution is important for determining force transmission performance of gear teeth in meshing. The distribution trend can be obtained by calculating the equation (5).
The mathematical model for modification of the tooth profile can be obtained by establishing the relationship between the pressure angle distribution and the modification function. The dependent variable is the modification DL and the independent variable is the pressure angle a.
The position of the reference point A is a major consideration in the modification design. It ensures the force transmission performance of the meshing segment is optimal. It is determined by the smallest profile pressure angle. The position is also dependent on the type of gear that is being modified. It is also influenced by the tooth backlash.
The mathematical model governing the pressure angle distribution is developed with DL=f(a). It is a piecewise function that determines the pressure angle distribution of a tooth profile. It can also be expressed as DL=ph.
The pressure angle of a tooth is also an angle between the common normal direction at the meshing point and the rotation velocity direction of the cycloid gear.
Planetary gearboxes vs cycloidal gearboxes
Generally, there are two types of gearboxes that are used for motion control applications: cycloidal gearbox and planetary gearbox. Cycloid gearboxes are used for high-frequency motions, while planetary gearboxes are suitable for low-speed applications. Both are highly accurate and precise gearboxes that are capable of handling heavy loads at high cycle rates. But they have different advantages and disadvantages. So, engineers need to determine which type of gearbox is best suited for their application.
Cycloid gearboxes are commonly used in industrial automation. They provide excellent performance with ratios as low as 10:1. They offer a more compact design, higher torque density and greater overload protection. They also require less space and are less expensive than planetary gearboxes.
On the other hand, planetary gearboxes are lightweight and offer a higher torque density. They are also capable of handling higher ratios. They have a longer life span and are more precise and durable. They can be found in a variety of styles, including square-framed, round-framed and double-frame designs. They offer a wide range of torque and speed capabilities and are used for numerous applications.
Cycloid gearboxes can be manufactured with different types of cycloidal cams, including single or compound cycloidal cams. Cycloid cams are cylindrical elements that have cam followers that rotate in an eccentric fashion. The cam followers act like teeth on the internal gear. Cycloid cams are a simple concept, but they have numerous advantages. They have a low backlash over extended periods of time, allowing for more accurate positioning. They also have internal compressive stresses and an overlap factor between the rolling elements.
Planetary gearboxes are characterized by three basic force-transmitting elements: ring gear, sun gear, and planet gear. They are generally two-stage gearboxes. The sun gear is attached to the input shaft, which in turn is attached to the servomotor. The ring gear turns the sun gear and the planet gear turns the output shaft.

Cyclone Gearbox Vs Involute Gearbox
Whether you’re using a cycloidal gearbox or an involute gearbox for your application, there are a few things you should know. This article will highlight some of those things, including: cycloidal gearbox vs involute gearbox, weight, compressive force, precision, and torque density.
Compressive force
Several studies have been carried out to analyze the static characteristics of gears. In this article, the authors investigate the structural and kinematic principles of a cycloidal gearbox. The cycloidal gearbox is a gearbox that uses an eccentric bearing inside a rotating frame. It has no common pinion-gear pair, and is therefore ideal for a high reduction ratio.
The purpose of this paper is to investigate the stress distribution on a cycloidal disc. Various gear profiles are investigated in order to study the load distribution and dynamic effects.
Cycloidal gearboxes are subject to compression and backlash, which require the use of proper ratios for the bearing rate and the TSA. The paper also focuses on the kinematic principles of the reducer. In addition, the authors use standard analysis techniques for the shaft/gear and the cycloidal disc.
The authors previously worked on a rigid body dynamic simulation of a cycloidal reducer. The analysis used a trochoidal profile on the cycloidal disc periphery. The trochoidal profile is obtained from a manufacturing drawing and takes into account the tolerances.
The mesh density in the cycloidal disc captures the exact geometry of the parts. It provides accurate contact stresses.
The cycloidal disc consists of nine lobes, which move by one lobe per rotation of the drive shaft. However, when the disc is rotated around the pins, the cycloidal disc does not move around the center of gravity. Therefore, the cycloidal disc shares torque load with five outer rollers.
A low reduction ratio in a cycloidal gearbox results in a higher induced stress in the cycloidal disc. This is due to the bigger hole designed to reduce the material inside the disc.
Torque density
Several types of magnetic gearboxes have been studied. Some magnetic gearboxes have a higher torque density than others, but they are still not able to compete with the mechanical gearboxes.
A new high torque density cycloidal magnetic gearbox using Halbach rotors has been developed and is being tested. The design was validated by building a CPCyMG prototype. The results showed that the simulated slip torque was comparable to the experimental slip torque. The peak torque measured was a p3 = 14 spatial harmonic, and it corresponds to the active region torque density of 261.4 N*m/L.
This cycloidal gearbox also has a high gear ratio. It has been tested to achieve a peak torque of 147.8 Nm, which is more than double the torque density of the traditional cycloidal gearbox. The design incorporates a ferromagnetic back-support that provides mechanical fabrication support.
This cycloidal gearbox also shows how a small diameter can achieve a high torque density. It is designed with an axial length of 50mm. The radial deflection forces are not serious at this length. The design uses a small air gap to reduce the radial deflection forces, but it is not the only design option.
The trade-off design also has a high volumetric torque density. It has a smaller air gap and a higher mass torque density. It is feasible to make and mechanically strong. The design is also one of the most efficient in its class.
The helical gearing design is a newer technology that brings a higher level of precision to a cycloidal gearbox. It allows a servomotor to handle a heavy load at high cycle rates. It is also useful in applications that require smaller design envelopes.
Weight
Compared to planetary gearboxes, the weight of cycloidal gearboxes is not as significant. However, they do provide some advantages. One of the most significant features is their backlash-free operation, which helps them deliver smooth and precise movement.
In addition, they provide high efficiency, which means that servo motors can run at higher speeds. The best part is that they do not need to be stacked up in order to achieve a high ratio.
Another advantage of cycloidal gearboxes is that they are usually less expensive than planetary gearboxes. This means that they are suitable for the manufacturing industry and robotics. They are also suited for heavy-duty robots that require a robust gearbox.
They also provide a better reduction ratio. Cycloidal gears can achieve reduction ratios from 30:1 to 300:1, which is a huge improvement over planetary gears. However, there are few models available that provide a ratio below 30:1.
Cycloidal gears also offer more resistance to wear, which means that they can last longer than planetary gears. They are also more compact, which helps them achieve high ratios in a smaller space. The design of cycloidal gears also makes them less prone to backlash, which is one of the major shortcomings of planetary gearboxes.
In addition, cycloidal gears can also provide better positioning accuracy. In fact, this is one of the primary reasons for choosing cycloidal gears over planetary gears. This is because the cycloid disc rotates around a bearing independently of the input shaft.
Compared to planetary gearboxes, cycloidal gears are also much shorter. This means that they provide the best positioning accuracy. They are also 50% lighter, meaning that they have a smaller diameter.
Precision
Several experts have studied the cycloidal gearbox in precision reducers. Their research mainly focuses on the mathematical model and the method for precision evaluation of cycloidal gears.
The traditional modification design of cycloidal gears is mainly realized by setting various machining parameters and center position of the grinding wheel. But it has some disadvantages because of unstable meshing accuracy and uncontrollable tooth profile curve shape.
In this study, a new method of modification design of cycloidal gears is proposed. This method is based on the calculation of meshing backlash and pressure angle distribution. It can effectively pre-control the transmission accuracy of cycloid-pin gear. It can also ensure good meshing characteristics.
The proposed method can be applied in the manufacture of rotary vector reducers. It is also applicable in the precision reducer for robots.
The mathematical model for cycloidal gears can be established with the pressure angle a as a dependent variable. It is possible to calculate the pressure angle distribution and the profile pressure angle. It can also be expressed as DL=f(a). It can be applied in the design of precision reducers.
The study also considers the root clearance, the backlash of gear teeth and the profile angle. These factors have a direct effect on the transmission performance of cycloidal gear. It also indicates the higher motion accuracy and the smaller backlash. The modified profile can also reflect the smaller transmission error.
In addition, the proposed method is also based on the calculation of lost motion. It determines the angle of first tooth contacts. This angle is an important factor affecting the modification quality. The transmission error after the second cycloid method is the least.
Finally, a case study on the CZPT RV-35N gear pair is shown to prove the proposed method.
Involute gears vs cycloidal gears
Compared to involute gears, cycloidal gears have a lower noise, less friction, and last longer. However, they are more expensive. Cycloidal gears can be more difficult to manufacture. They may be less suitable for certain applications, including space manipulators and robotic joints.
The most common gear profile is the involute curve of a circle. This curve is formed by the endpoint of an imaginary taut string unwinding from the circle.
Another curve is the epicycloid curve. This curve is formed by the point rigidly attached to the circle rolling over another circle. This curve is difficult to produce and is much more expensive to produce than the involute curve.
The cycloid curve of a circle is also an example of the multi-cursor. This curve is generated by the locus of the point on the circle’s circumference.
The cycloid curve has the same diameter as the involute curve, but is tangentially curving along the circle’s diameter. This curve is also classified as ordinary. It has several other functions. The FE method was used to analyze the strain state of cycloidal speed reducers.
There are many other curves, but the involute curve is the most widely used gear profile. The involute curve of a circle is a spiraling curve traced by the endpoint of an imaginary tautstring.
Involute gears are a lot like a set of Lego blocks. They are a lot of fun to play with. They also have a lot of advantages. For example, they can handle center sifts better than cycloidal gears. They are also much easier to manufacture, so the cost of involute teeth is lower. However, they are obsolete.
Cycloidal gears are also more difficult to manufacture than involute gears. They have a convex surface, which leads to more wear. They also have a simpler shape than involute gears. They also have less teeth. They are used in rotary motions, such as in the rotors of screw compressors.

The Advantages of Using a Cyclone Gearbox
Using a cycloidal gearbox to drive an input shaft is a very effective way to reduce the speed of a machine. It does this by reducing the speed of the input shaft by a predetermined ratio. It is capable of very high ratios in relatively small sizes.
Transmission ratio
Whether you’re building a marine propulsion system or a pump for the oil and gas industry, there are certain advantages to using cycloidal gearboxes. Compared to other gearbox types, they’re shorter and have better torque density. These gearboxes also offer the best weight and positioning accuracy.
The basic design of a cycloidal gearbox is similar to that of a planetary gearbox. The main difference is in the profile of the gear teeth.
Cycloid gears have less tooth flank wear and lower Hertzian contact stress. They also have lower friction and torsional stiffness. These advantages make them ideal for applications that involve heavy loads or high-speed drives. They’re also good for high gear ratios.
In a cycloidal gearbox, the input shaft drives an eccentric bearing, while the output shaft drives the cycloidal disc. The cycloidal disc rotates around a fixed ring, and the pins of the ring gear engage the holes in the disc. The pins then drive the output shaft as the disc rotates.
Cycloid gears are ideal for applications that require high gear ratios and low friction. They’re also good for applications that require high torsional stiffness and shock load resistance. They’re also suitable for applications that require a compact design and low backlash.
The transmission ratio of a cycloidal gearbox is determined by the number of lobes on the cycloidal disc. The n=n design of the cycloidal disc moves one lobe per revolution of the input shaft.
Cycloid gears can be manufactured to reduce the gear ratio from 30:1 to 300:1. These gears are suitable for high-end applications, especially in the automation industry. They also offer the best positioning accuracy and backlash. However, they require special manufacturing processes and require non-standard characteristics.
Compressive force
Compared with conventional gearboxes, the cycloidal gearbox has a unique set of kinematics. It has an eccentric bearing in a rotating frame, which drives the cycloidal disc. It is characterized by low backlash and torsional stiffness, which enables geared motion.
In this study, the effects of design parameters were investigated to develop the optimal design of a cycloidal reducer. Three main rolling nodes were studied: a cycloidal disc, an outer race and the input shaft. These were used to analyze the motion related dynamic forces, which can be used to calculate stresses and strains. The gear mesh frequency was calculated using a formula, which incorporated a correction factor for the rotating frame of the outer race.
A three-dimensional finite element analysis (FEA) study was conducted to evaluate the cycloidal disc. The effects of the size of the holes on the disc’s induced stresses were investigated. The study also looked at the torque ripple of a cycloidal drive.
The authors of this study also explored backlash distribution in the output mechanism, which took into account the machining deviations and structure and geometry of the output mechanism. The study also looked at the relative efficiency of a cycloidal reducer, which was based on a single disc cycloidal reducer with a one-tooth difference.
The authors of this study were able to deduce the contact stress of the cycloidal disc, which is calculated using the material-based contact stiffness. This can be used to determine accurate contact stresses in a cycloidal gearbox.
It is important to know the ratios needed for calculation of the bearing rate. This can be calculated using the formula f = k (S x R) where S is the volume of the element, R is the mass, k is the contact stiffness and f is the force vector.
Rotational direction
Unlike the conventional ring gear which has a single axis of rotation, cycloidal gearbox has three rotational axes which are parallel and are located in a single plane. A cycloidal gearbox has excellent torsional stiffness and shock load capacity. It also ensures constant angular velocity, and is used in high-speed gearbox applications.
A cycloidal gearbox consists of an input shaft, a drive member and a cycloidal disc. The disc rotates in one direction, while the input shaft rotates in the opposite direction. The input shaft eccentrically mounts to the drive member. The cycloidal disc meshes with the ring-gear housing, and the rotational motion of the cycloidal disc is transferred to the output shaft.
To calculate the rotational direction of a cycloidal gearbox, the cycloid must have the correct angular orientation and the centerline of the cycloid should be aligned with the center of the output hole. The cycloid’s shortest length should be equal to the radius of the pin circle. The cycloid’s largest radius should be the size of the bearing’s exterior diameter.
A single-stage gear will not have much space to work with, so you’ll need a multistage gear to maximize space. This is also the reason that cycloid gears are usually designed with a shortened cycloid.
To calculate the most efficient tooth profile for a cycloidal gear, a new method was devised. This method uses a mathematical model that uses the cycloid’s rotational direction and a few other geometric parameters. Using a piecewise function related to the distribution of pressure angle, the cycloid’s most efficient profile is determined. It is then superimposed on the theoretical profile. The new method is much more flexible than the conventional method, and can adapt to changing trends of the cycloidal profile.
Design
Several designs of cycloidal gearboxes have been developed. These gearboxes have a large reduction ratio in one stage. They are mainly used for heavy machines. They provide good torsional stiffness and shock load capacity. However, they also have vibrations at high RPM. Several studies have been conducted to find a solution to this problem.
A cycloidal gearbox is designed by calculating the reduction ratio of a mechanism. This ratio is obtained by the size of the input speed. This is then multiplied by the reduction ratio of the gear profile.
The most important factor in the design of a cycloidal gearbox is the load distribution along the width of the gear. Using this as a design criterion, the amplitude of vibration can be reduced. This will ensure that the gearbox is working properly. In order to generate proper mating conditions, the trochoidal profile on the cycloidal disc periphery must be defined accurately.
One of the most common forms of cycloidal gears is circular arc toothing. This is the most common type of toothing used today.
Another form of gear is the hypocycloid. This form requires the rolling circle diameter to be equal to half the base circle diameter. Another special case is the point tooth form. This form is also called clock toothing.
In order to make this gear profile work, the initial point of contact must remain fixed to the edge of the rolling disk. This will generate the hypocycloid curve. The curve is traced from this initial point.
To investigate this gear profile, the authors used a 3D finite element analysis. They used the mathematical model of gear manufacturing that included kinematics parameters, output moment calculations, and machining steps. The resulting design eliminated backlash.
Sizing and selection
Choosing a gearbox can be a complex task. There are many factors that need to be taken into account. You need to determine the type of application, the required speed, the load, and the ratio of the gearbox. By gaining this information, you can find a solution that works best for you.
The first thing you need to do is find the proper size. There are several sizing programs available to help you determine the best gearbox for your application. You can start by drawing a cycloidal gear to help you create the part.
During sizing, it is important to consider the environment. Shock loads, environmental conditions, and ambient temperatures can increase wear on the gear teeth. The temperature also has a significant impact on lubrication viscosities and seal materials.
You also need to consider the input and output speed. This is because the input speed will change your gearbox ratio calculations. If you exceed the input speed, you can damage the seals and cause premature wear on the shaft bearings.
Another important aspect of sizing is the service factor. This factor determines the amount of torque the gearbox can handle. The service factor can be as low as 1.4, which is sufficient for most industrial applications. However, high shock loads and impact loads will require higher service factors. Failure to account for these factors can lead to broken shafts and damaged bearings.
The output style is also important. You need to determine if you want a keyless or keyed hollow bore, as well as if you need an output flange. If you choose a keyless hollow bore, you will need to select a seal material that can withstand the higher temperatures.

How to Use a Cyclone Gearbox
Often, a cycloidal gearbox is used in order to achieve a torque transfer from a motor or pump. This type of gearbox is often a common choice as it has a number of advantages over a regular gearbox. Its main advantage is that it is easy to make, which means that it can be incorporated into a variety of applications. However, if you want to use a cycloidal gearbox, there are a few things that you need to know. These include the operation principle, the structure and the dynamic and inertial effects that come with it.
Dynamic and inertial effects
Several studies have been carried out on the static and dynamic properties of cycloidal gears. The study of these effects is beneficial in assisting optimal design of cycloidal speed reducers.
In this paper, the dynamic and inertial effects of a two-stage cycloidal speed reducer have been investigated using the CZPT program package. Moreover, a new model for cycloidal reducers based on non-linear contact dynamics has been developed. The new model aims to predict several operational conditions.
The normal excitation contact force for the cycloid discs of the first and second stage is very similar. However, the total deformation at the contact point is different. This effect is mainly due to the system’s own oscillations. The cycloid discs of the second stage turn around the ring gear roller with a 180deg angle. This angle is a significant contributor to the torque loads. The total excitation force on the cycloid discs of first and second stage is 1848 N and 2068.7 N, respectively.
In order to analyze the contact stress, different gear profiles were investigated. The mesh density was considered as an important design criterion. It was found that a bigger hole reduces the material content of the cycloidal disc and results in more stresses.
Moreover, it is possible to reduce the contact forces in a more efficient manner by changing the geometric parameters. This can be done by mesh refinement along the disc width. The cycloidal disc has the greatest influence on the output results.
The efficiency of a cycloidal drive increases with the increase in load. The efficiency of a cycloidal reducer also depends on the eccentricity of the input shaft and the cycloidal plate. The efficiency curve for small loads is linear. However, for the larger loads, the efficiency curve becomes more non-linear. This is because the stiffness of the cycloid reducer increases as the load increases.
Structure
Despite the fact that it looks like a complicated engineering puzzle, the construction of a cycloidal gearbox is actually quite simple. The key elements are the base, the load plate and the thrust bearing. All these elements work together to create a stable, compact gearbox.
The base is a circular section with several cylindrical pins around its outer edge. The pins are fixed on a fixed ring that holds them in a circular path. The ring serves as a reference circle. The circle’s size is approximately 5mm in diameter.
The load plate is a series of threaded screw holes. These are arranged 15mm away from the center. These are used to anchor external structures. The load plate must be rotated around the X and Y axis.
The thrust bearing is placed on top of the load plate. The bearing is made of an internal diameter of 35mm and an external diameter of 52mm. It is used to allow rotation around the Z axis.
The cycloidal disc is the centerpiece of the cycloidal gearbox. The disc has holes for the pins that drive the output shaft. The holes are larger than those used in output roller pins. The disc also has a reduced eccentricity.
The pins are attached to the cycloidal disc by rolling pins. The pins are made of a material that provides mechanical support for the drive during high-torque situations. The pins have a 9mm external diameter. The disc has a number of lobes and is rotated by one lobe per shaft revolution.
The cycloidal gearbox also has a top cover that helps keep the components together. The cover has a pocket for tools. The top cover also has threads that screw into the casing.
Operation principle
Among many types of gear transmissions, cycloidal gearboxes are used in heavy machinery and multi-axis robots. They are highly effective, compact and capable of high ratios. In addition, they have an overload capability.
Cycloid disks are driven by eccentric shafts that rotate around fixed ring pins. Roller pins of the pin disc engage with holes in the cycloidal disc. These roller pins drive the pin disc and the pin disc transfers the motion to the output shaft.
Unlike conventional gear drives, cycloidal drives have low backlash and high torsional stiffness. They are ideally suited to heavy loads and all drive technologies. The lower mass and compact design of the cycloidal disk also contributes to its high efficiency and positioning accuracy.
The cycloidal disc plays a central role in the gearbox kinematics. It rotates around a fixed ring in a circle. When the disc is pushed against the ring gear, the pins engage with the disc and the roller pins rotate around the pins. This rotating motion generates vibration, which travels through the driven shafts.
Cycloid discs are typically designed with a short cycloid, so that the eccentricity is minimized. This reduces unbalance forces at high speeds. Ideally, the number of lobes on the cycloid is smaller than the number of surrounding pins. This reduces the amount of Hertzian contact stress.
Unlike planetary gears, cycloidal gears have high accuracy and are capable of withstanding shock loads. They also experience low friction and less wear on tooth flanks. They also have higher efficiency and load capacity.
Cycloid gears are generally more difficult to manufacture than involute gears. Cycloid gears are not suitable for stacking gear stages. They require extreme accuracy for manufacturing. However, their smaller size and low backlash, high torsional stiffness, and low vibration make them ideal for use in heavy machines.
Involute gear tooth profile
Almost all gears are manufactured with an involute gear tooth profile. Cycloid gears are also produced with this profile. Compared with involute gears, cycloid gears are stronger and can transmit more power. However, they can also be more difficult to manufacture. This makes them costlier.
The involute gear tooth profile is a smooth curve. It is derived from the involute curve of a circle. A tangent to the base circle is the normal at any point of an involute.
This curve has properties that allow the involute gear teeth to transfer motion in perpendicular direction. It is also the path traced by the end of the string unwrapping from a cylinder.
An involute profile has the advantage of being easy to manufacture. It also allows for smooth meshing despite misalignment of the centre distance. This profile is also preferred over a cycloid tooth profile, but it is not the best in every regard.
Cycloid gear teeth are also made of two curves. Unlike involute teeth, cycloid gear teeth have a consistent radius. Cycloid gears are less likely to produce noise. But they are also more expensive to manufacture.
Involute teeth are easier to manufacture because they have only one curve. Cycloid gears can also be made with a rack type cutter. This makes them cheaper to manufacture. However, they require an expert design. They can also be manufactured with a gear shaper that includes a pinion cutter.
The tooth profiles that satisfy the law of gear-tooth action are sometimes called conjugate profiles. The involute profile is the most common of these. It allows for constant torque transmission.
Backlash
Typically, cycloidal drives provide a high ratio of transmission with no backlash. This is because the cycloid disc is driven by an eccentric shaft. During rotation, the cycloid disc rotates around a fixed ring. This ring also rotates independently of the center of gravity.
The cycloid disc is typically shortened to reduce the eccentricity. This helps to minimize the unbalance forces that may occur at high speeds. The cycloid also offers a larger gear ratio than traditional gears. This provides a better positional accuracy.
Cycloid drives also have a high torsional stiffness. This provides greater torsional resilience and shock load capabilities. This is important for a number of reasons, such as in heavy-duty applications.
Cycloid drives also have lower mass. These benefits make them ideally suited for all drive technologies. The design also allows for higher torsional stiffness and service life. These drives also have a much smaller profile.
Cycloid drives are also used to reduce speed. Because of the high torsional stiffness of the cycloid, they also have high positioning accuracy.
Cycloid drives are well-suited to a variety of applications, including electric motors, generators, and pump motors. They are also highly resistant to shock loads, which is important in a variety of applications. This design is ideal for applications that require a large transmission ratio in a compact design.
Cycloid drives also have the advantage of minimizing the clearance between the mating components. This helps to eliminate interference and ensure a positive fit. This is particularly important in gearboxes. It also allows for the use of a load cell and potentiometer to determine the backlash of the gearbox.
