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.helical gearbox

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.

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.helical gearbox

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.helical gearbox

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.
