What is a Cycloidal Gearbox?

A cycloidal gearbox, also known as a cycloidal drive, is a type of gearing mechanism that utilizes the principle of cycloidal motion for power transmission. It consists of several components, including a high-speed input shaft, a set of cycloidal pins or rollers, and an outer stationary ring with lobed profiles.

The operation of a cycloidal gearbox involves a unique mechanism:

  1. Input Shaft: The high-speed input shaft is connected to the driving source, such as an electric motor. It transfers rotational motion to the cycloidal pins.
  2. Cycloidal Pins or Rollers: These pins or rollers are typically arranged around the input shaft in a circular pattern. As the input shaft rotates, the cycloidal pins also rotate, causing them to engage with the lobes on the outer stationary ring.
  3. Outer Stationary Ring: The outer ring has lobed profiles, and it remains stationary during operation. The lobes of the outer ring interact with the cycloidal pins or rollers, causing them to move in a unique motion known as epicycloidal or hypocycloidal motion.

The interaction between the cycloidal pins and the lobed profiles of the outer ring results in smooth and controlled motion transmission. The mechanism provides advantages such as high torque capacity, compact size, and precise positioning capabilities.

Cycloidal gearboxes are widely used in various applications, including robotics, automation, packaging machinery, and other industrial systems where high torque, precision, and compact design are essential.

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.

cycloidal gearbox

Principle of Cycloidal Gearing

Cycloidal gearing is a mechanism that utilizes the unique shape of cycloidal discs to achieve motion transmission. The principle involves the interaction between two main components: the input disc and the output disc.

The input disc has lobes with pins, while the output disc has lobes with matching holes. The lobes on both discs are not perfectly circular but are shaped in a cycloidal profile. As the input disc rotates, the pins on its lobes engage with the holes in the output disc’s lobes.

As the input disc rotates, the pins move along the cycloidal paths, causing the output disc to rotate. The interaction between the pins and the holes results in smooth and continuous motion transfer. The unique shape of the cycloidal profile ensures that there is always at least one point of contact between the pins and the holes, allowing for efficient torque transmission and reduced wear.

Cycloidal gearing provides advantages such as high torque capacity, compact size, and precision motion. However, due to the complex shape of the components and the continuous engagement, manufacturing and assembly of cycloidal gearboxes can be intricate.

Calculation of Reduction Ratio in a Cycloidal Gearbox

The reduction ratio in a cycloidal gearbox can be calculated using the following formula:

Reduction Ratio = (Number of Input Pins + Number of Output Pins) / Number of Output Pins

In a cycloidal gearbox, the input pins engage with the lobes of the cam disc, while the output pins are engaged with the cycloidal pins of the output rotor. The reduction ratio determines the relationship between the number of input and output pins engaged at any given time.

For example, if a cycloidal gearbox has 7 input pins and 14 output pins engaged, the reduction ratio would be:

Reduction Ratio = (7 + 14) / 14 = 1.5

This means that for every 1 revolution of the input pins, the output rotor will complete 1.5 revolutions. The reduction ratio is a key parameter that influences the output speed and torque of the cycloidal gearbox.

What is a Cycloidal Gearbox?

A cycloidal gearbox, also known as a cycloidal drive, is a type of gearing mechanism that utilizes the principle of cycloidal motion for power transmission. It consists of several components, including a high-speed input shaft, a set of cycloidal pins or rollers, and an outer stationary ring with lobed profiles.

The operation of a cycloidal gearbox involves a unique mechanism:

  1. Input Shaft: The high-speed input shaft is connected to the driving source, such as an electric motor. It transfers rotational motion to the cycloidal pins.
  2. Cycloidal Pins or Rollers: These pins or rollers are typically arranged around the input shaft in a circular pattern. As the input shaft rotates, the cycloidal pins also rotate, causing them to engage with the lobes on the outer stationary ring.
  3. Outer Stationary Ring: The outer ring has lobed profiles, and it remains stationary during operation. The lobes of the outer ring interact with the cycloidal pins or rollers, causing them to move in a unique motion known as epicycloidal or hypocycloidal motion.

The interaction between the cycloidal pins and the lobed profiles of the outer ring results in smooth and controlled motion transmission. The mechanism provides advantages such as high torque capacity, compact size, and precise positioning capabilities.

Cycloidal gearboxes are widely used in various applications, including robotics, automation, packaging machinery, and other industrial systems where high torque, precision, and compact design are essential.

Condition Monitoring of Cyclone Gearboxes

Whether you’re considering using a cycloidal gearbox in your home, office, or garage, you’ll want to make sure it’s made of quality material. You also want to make sure it’s designed properly, so it won’t be damaged by vibrations.

Planetary gearboxes

Compared to cycloidal gearboxes, planetary gearboxes are lighter and more compact, but they lack the precision and durability of the former. They are better suited for applications with high torque or speed requirements. For this reason, they are usually used in robotics applications. But, cycloidal gearboxes are still better for some applications, including those involving shock loads.
There are many factors that affect the performance of gearboxes during production. One of these is the number of teeth. In the case of planetary gearboxes, the number of teeth increases with the number of planets. The number of teeth is reduced in cycloidal gearboxes, which results in higher transmission ratios. These gearboxes also have lower breakaway torques, which means that they can be controlled more easily by the user.
A cycloid gearbox is comprised of three main parts: the ring gear, the sun gear, and the input shaft. The ring gear is fixed in the gearbox, while the sun gear transmits the rotation to the planet gears. The input shaft transfers motion to the sun gear, which in turn transmits it to the output shaft. The output shaft has a larger torque than the input shaft.
Cycloid gears have better torsional stiffness, lower wear, and lower Hertzian contact stress. However, they are also larger in size and require highly accurate manufacturing. Cycloid gears can be more difficult to manufacture than involute gears, which require large amounts of precision.
Cycloid gears can offer transmission ratios up to 300:1, and they can do this in a small package. They also have lower wear and friction, which makes them ideal for applications that require a high transmission ratio.
Cycloid gearboxes are usually equipped with a backlash of about one angular minute. This backlash provides the precision and control necessary for accurate movement. They also provide low wear and shock load capacity.
Planetary gearboxes are available in single and two-stage designs, which increase in length as stages are added. In addition to the two stages, they can be equipped with an optional output bearing, which takes up mounting space. In some applications, a third stage is also available.

Involute gears

Generally, involute gears are more complex to manufacture than cycloidal gears. For example, an involute gear tooth profile has a single curve while a cycloidal gear tooth profile has two curves. In addition, the involute curve is not within the base circle.
The involute curve is a very important component of a gear tooth and it can significantly influence the quality of contact meshing between teeth. Various works have been done on the subject, mainly focusing on the operating principles. In addition, the most important characteristic of the double-enveloping cycloid drive is its double contact lines between the meshing tooth pairs.
Cycloid gears are more powerful, less noisy, and last longer than involute gears. They also require less manufacturing operations during production. However, cycloid gears are more expensive than involute gears. Involute gears are more commonly used in linear motions while cycloid gears are used for rotary motions.
Although cycloid gears are more technically advanced, involute gears have the superior quality and are more aesthetically pleasing. Cycloid gears are used in various industrial applications such as pumps and compressors. They are also widely used in the watch industry. Nevertheless, involute gears have not yet replaced cycloid gears in the watch industry.
The cycloid disc has a number of pins around its outer edge, while an involute gear has only a single curve for the teeth. In addition, cycloid gears have a more robust and reliable design. Involute gears, on the other hand, have a cheaper rack cutter and less expensive involute teeth.
The cycloid disc’s transmission accuracy is about 98.5%, while the ring gear’s transmission accuracy is about 96%. The cycloid disc’s rotational velocity has a magnitude of 3 rad/s. A small change in the center distance does not affect the transmission accuracy. However, rotational velocity fluctuation can affect the transmission accuracy.
Cycloid gears also have the cycloid gear disc’s rotational velocity. The disc has N lobes. However, the cycloid gear disc’s transmission accuracy is still not perfect. This is because of the large rotational angles between the lobes. This also makes it difficult to manufacture.helical gearbox

Vibrations

Using modern techniques for vibration diagnostics and data-driven methods, this article presents a new approach to condition monitoring of cycloidal gearboxes. This approach focuses on detecting the root cause of gearbox failure. The article aims to provide a unified approach to gear designers.
A cycloidal gearbox is a high-precision gearbox that is used in heavy-duty machines. It has a large reduction ratio, which makes it necessary to have a very large input speed. Cycloid gears have high accuracy, but they are susceptible to vibration issues. In this article, the authors describe how a cycloidal gearbox works and how vibrations are measured. They also show how this gearbox can be used to detect faults.
The gearbox is used in positioners, multi-axis robots, and heavy-duty machines. The main characteristics of this gearbox are the high accuracy, the overload capacity, and the large reduction ratio.
There is little documentation on vibrations and condition monitoring of cycloidal gearboxes. The authors describe their approach to the problem, using a cycloidal gearbox and a testing bench. Their approach involves measuring the frequency of the gearbox with different input speeds.
The results show a good separation between the healthy and damaged states. Fault frequencies show up in the lower orders of frequencies. Faults can be detected using binning, which eliminates the need for a tachometer. In addition, binning is combined with Principal Component Analysis to determine the state of the gearbox.
This method is compared to traditional techniques. In addition, the results show how binning can be used to calculate the defect frequencies of the bearings. It is also used to determine the frequencies of the components.
The signals from the test bench are acquired using four sensors. These sensors are medium sensitivity 100 mV/g accelerometers. The signals are then processed using different signal processing techniques. The results show that the vibration signals are correlated with the internal motion of the gearbox. This information is used to identify the internal frequency of the transmission.
The frequency analysis of vibration signals is performed in cyclostationary and noncyclostationary conditions. The signals are then analyzed to determine the magnitude of the gear meshing frequency.helical gearbox

Design

Using precision gearboxes, servomotors can now control heavy loads at high speed. Unlike cam indexing devices, cycloidal gears provide extremely accurate positioning and high torque. They also provide excellent torsional stiffness and shock load capacity.
Cycloid gears are specially designed to minimize vibration at high RPM. Unlike involute gears, they are not stacked, which reduces friction and forces experienced by each tooth. In addition, cycloidal gears have lower Hertzian contact stress.
Cycloid gears are often used in multi-axis robots for positioners. They can provide transmission ratios as high as 300:1 in a compact package. They are also used in first joints in heavy machines. However, they require extremely accurate manufacturing. They are also more difficult to produce than involute gears.
A cycloidal gearbox is a type of planetary gearbox. Cycloid gears are specially designed for high gear ratios. They also have the ability to provide a large reduction ratio in a single stage. They are increasingly used in first joints in heavy machines. They are also becoming more common in robotics.
In order to achieve a large reduction ratio, the input speed of the gear must be very high. Generally, the input speed is between 500 rpm and 4500 rpm. However, in some cases, the input speed may be lower.
A cycloid is formed by rolling a rolling circle on a base circle. The ratio between the rolling circle diameter and the base circle diameter determines the shape of the cycloid. A hypocycloid is formed by rolling primarily on the inside of the base circle, while an epicycloid is formed by rolling primarily on the outside of the base circle.
Cycloid gears have a very small backlash, which minimizes the forces experienced by each tooth. These gears also have a good torsional stiffness, low friction, and shock load capacity. They also provide the best positioning accuracy.
The cycloidal gearbox was designed and built at Radom University. The design was based on three different cycloidal gears. The first pair had the external profile at the nominal dimension, while the second pair had the profile minus tolerance. The load plate had threaded screw holes arranged 15 mm away from the center.

Distinguishing Features of Cycloidal Gearboxes

Cycloidal gearboxes, also known as cycloidal drives or cycloidal reducers, possess distinct characteristics that set them apart from other types of gearboxes:

  • Principle of Operation: Cycloidal gearboxes utilize the principle of cycloidal motion, where input shaft movement is transformed into eccentric motion of the cycloidal disc. This unique mechanism results in smooth and consistent output motion.
  • Compactness: Cycloidal gearboxes are renowned for their compact size and high torque density. The concentric design of the components contributes to their ability to transmit substantial torque in a relatively small package.
  • Tooth Profile: Cycloidal gearboxes employ specialized cycloidal teeth, which involve both pinwheel and roller gears. This distinctive tooth profile contributes to the characteristic smooth and vibration-free operation.
  • Reduction Mechanism: They often employ multi-lobed cam gears that interact with the pins on the cycloidal disc, resulting in multiple gear engagements per revolution and improved load distribution.
  • Motion Control: Cycloidal gearboxes offer high positional accuracy and motion control due to the eccentric motion of the disc, making them suitable for robotics, automation, and precision applications.
  • Backlash: They typically exhibit low backlash due to the nature of the engagement mechanism, making them advantageous for applications requiring precise and reversible motion.
  • Applications: Cycloidal gearboxes are commonly used in various industries, including robotics, packaging, material handling, printing, and more, where their compactness, precision, and efficiency are valued.

These distinguishing features contribute to the unique capabilities and benefits of cycloidal gearboxes in specific applications.

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.helical gearbox

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.helical gearbox

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.
