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.

helical gearbox

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. helical gearbox

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. helical gearbox

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.

How Does a Cycloidal Gearbox Work?

A cycloidal gearbox operates on the principle of cycloidal motion to transmit rotational power. It consists of a set of components that work together to achieve smooth and efficient motion transmission:

High-Speed Input Shaft: The gearbox is connected to a high-speed input shaft, typically driven by an electric motor or another power source.
Cycloidal Pins or Rollers: Surrounding the input shaft are a series of cycloidal pins or rollers arranged in a circular pattern. These pins interact with the lobed profiles of the outer stationary ring.
Outer Stationary Ring: The outer ring remains stationary and contains lobed profiles. The lobes are designed in a way that allows them to engage with the cycloidal pins as they rotate.
Motion Transmission: As the input shaft rotates, it causes the cycloidal pins to move along the circular path. The interaction between the cycloidal pins and the lobed profiles of the outer ring results in a unique motion known as epicycloidal or hypocycloidal motion.

This motion generates torque that is transferred from the input shaft to the output shaft of the gearbox. The main advantage of a cycloidal gearbox is its ability to provide high torque output in a compact design. The multiple points of contact between the pins and the lobes distribute the load, enhancing the gearbox’s load-carrying capacity.

Cycloidal gearboxes are known for their smooth and controlled motion, making them suitable for applications requiring precise positioning and high torque capabilities, such as robotics, automation, and industrial machinery.

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. helical gearbox

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. helical gearbox

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. helical gearbox

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.

Kinematics

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. helical gearbox

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.
