Product Description
Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.
Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc
Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.
How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

Can flexible couplings be used in servo motor and stepper motor applications?
Yes, flexible couplings are commonly used in both servo motor and stepper motor applications. They play a crucial role in connecting the motor shaft to the driven load while compensating for misalignments and providing other essential benefits:
- Servo Motor Applications: Servo motors require precise motion control and high responsiveness. Flexible couplings are well-suited for servo motor applications because they offer the following advantages:
- Misalignment Compensation: Servo motors are sensitive to misalignments, which can lead to decreased performance and increased wear. Flexible couplings can accommodate angular, parallel, and axial misalignments, ensuring that the motor and driven load remain properly aligned during operation.
- Vibration Damping: Flexible couplings help reduce vibrations, which is crucial for servo motor applications that require smooth and precise motion. By absorbing and dissipating vibrations, flexible couplings contribute to the overall stability and accuracy of the system.
- Backlash Minimization: Some flexible couplings have minimal to no backlash, making them suitable for high-precision servo motor applications where any play or clearance between components could affect performance.
- High Torque Capacity: Servo motors often require high torque transmission capabilities. Flexible couplings are available in various designs and materials, allowing for the selection of couplings with appropriate torque ratings for specific servo motor applications.
- Stepper Motor Applications: Stepper motors are commonly used in open-loop control systems where precise positioning is necessary. Flexible couplings are used in stepper motor applications due to the following reasons:
- Misalignment Tolerance: Stepper motors can experience misalignments, especially in dynamic applications. Flexible couplings can handle misalignments without introducing significant backlash or affecting the stepper motor’s accuracy.
- Cost-Effectiveness: Flexible couplings are often more cost-effective than other types of couplings, making them a practical choice for stepper motor applications, especially in cases where precision requirements are not as stringent as in servo motor systems.
- Shock Load Absorption: Some stepper motor applications involve abrupt starts and stops, leading to shock loads. Flexible couplings can absorb these shocks and protect the motor and driven load from damage.
- Simplicity: Flexible couplings are simple in design and easy to install, making them a popular choice in various stepper motor applications.
Overall, flexible couplings offer valuable benefits in both servo motor and stepper motor applications. They help improve system performance, reduce wear on components, and enhance the overall reliability of the motion control systems they are employed in.
How does a flexible coupling help in torque and rotational speed control?
A flexible coupling plays a crucial role in torque and rotational speed control in rotating machinery. It offers several benefits that contribute to efficient power transmission and help maintain desired operating conditions:
- Torque Transmission: Flexible couplings transmit torque from one shaft to another while accommodating misalignments. They provide a reliable connection that allows the driving shaft to transfer rotational force (torque) to the driven shaft without causing undue stress on the connected components.
- Smooth Power Transmission: Flexible couplings help reduce shocks and vibrations that can occur during startup, shutdown, or sudden load changes. By damping these vibrations, the coupling ensures smooth power transmission and protects the connected equipment from unnecessary wear.
- Rotational Speed Control: In certain applications, especially those involving precision motion control, maintaining consistent rotational speed is critical. Flexible couplings can help by minimizing backlash and torsional wind-up. Backlash refers to the play or gap between the coupling’s components, while torsional wind-up is the twisting deformation that can occur under torque load. Flexible couplings with low backlash and high torsional stiffness contribute to accurate rotational speed control.
- Compensation for Misalignment: Rotating machinery may experience misalignment due to various factors such as thermal expansion, foundation settling, or machining tolerances. Flexible couplings accommodate angular, parallel, and axial misalignments, which helps in maintaining proper alignment between the shafts and reduces unnecessary torque variations.
- Protection from Overloads: Flexible couplings can act as a mechanical fuse by disengaging or slipping when subjected to excessive torque loads. This feature protects the connected components from damage caused by sudden overloads or jamming events.
- Energy Efficiency: Certain types of flexible couplings, such as elastomeric couplings or beam couplings, have low mass and inertia. This characteristic reduces energy losses and contributes to overall system efficiency.
By providing reliable torque transmission, smooth power transfer, rotational speed control, and compensation for misalignment, flexible couplings optimize the performance and longevity of rotating machinery. Additionally, they enhance the safety and efficiency of various industrial processes by protecting equipment from excessive loads and ensuring smooth operation in diverse applications.
What role does a flexible coupling play in reducing downtime and maintenance costs?
A flexible coupling plays a significant role in reducing downtime and maintenance costs in industrial machinery and rotating equipment. Here are the key ways in which flexible couplings contribute to these benefits:
- Misalignment Compensation: One of the primary functions of a flexible coupling is to accommodate misalignment between two connected shafts. Misalignment can occur due to various factors such as thermal expansion, foundation settling, or manufacturing tolerances. By allowing for misalignment, flexible couplings reduce the transmission of harmful forces and stresses to connected components, minimizing wear and preventing premature failures that could lead to costly downtime and repairs.
- Vibration Damping: Flexible couplings have inherent damping properties due to the elastomeric or flexible elements they incorporate. These elements absorb and dissipate vibration and shock loads that may arise from the operation of rotating machinery. By dampening vibrations, flexible couplings protect the connected equipment from excessive wear and fatigue, extending their service life and reducing the need for frequent maintenance or replacement.
- Shock Load Absorption: In applications where sudden loads or shocks are common, such as in heavy machinery or high-speed equipment, flexible couplings act as shock absorbers. They can absorb and dissipate the impact energy, preventing damage to the machinery and minimizing downtime caused by unexpected failures or breakdowns.
- Easy Installation and Alignment: Flexible couplings are designed for ease of installation and alignment. Unlike rigid couplings that require precise shaft alignment, flexible couplings can tolerate some degree of misalignment during installation. This feature simplifies the setup process, reduces installation time, and lowers the risk of misalignment-related issues, ultimately minimizing downtime during initial installation or replacement of couplings.
- Reduced Maintenance Frequency: The ability of flexible couplings to handle misalignment and dampen vibrations results in reduced wear on bearings, seals, and other connected components. Consequently, the frequency of maintenance intervals can be extended, reducing the need for frequent inspections and component replacements. This directly translates to lower maintenance costs and less downtime for maintenance tasks.
- Equipment Protection: By reducing the transmission of shock loads and vibrations, flexible couplings act as protective barriers for connected equipment. They help prevent catastrophic failures and subsequent damage to expensive machinery, avoiding unplanned shutdowns and costly repairs.
Overall, flexible couplings are critical components that improve the reliability and longevity of rotating equipment. Their ability to handle misalignment, dampen vibrations, and protect against shock loads contributes to reduced downtime, lower maintenance costs, and increased productivity in industrial applications.

Programming With Couplings
A coupling is a mechanical device that connects two shafts together and transmits power. Its purpose is to join rotating equipment and allows some degree of end-movement or misalignment. There are many different types of couplings. It’s important to choose the right one for your application.
Mechanical connection between two shafts
There are many ways to achieve mechanical connection between two shafts, including the use of a coupling. One common type is the beam coupling, which is also known as a helical coupling. It is used for transmission of torque between two shafts. This type of connection accommodates axial, parallel and angular misalignments.
The hubs and shafts of a worm gear are connected together by a coupling. This mechanical connection allows one shaft to turn another without causing a mechanical failure. This type of coupling is made from sliding or rubbing parts to transfer torque. However, the coupling is not designed to withstand jerks, so it isn’t suitable for high-speed applications.
The use of a coupling is common in machinery and equipment. It helps transmit power from one drive shaft to the other, while adding mechanical flexibility. It is also useful for reducing the impact and vibration caused by misalignment. It also protects the drive shaft components from wear and tear.
A double-hook coupling can be used to provide a uniform angular velocity at the driven shaft. Another example is a double-jointed coupling. A double-jointed coupling can be used to connect shafts that are not directly intersecting. The double-jointed yoke can be used for the same purpose.
A shaft coupling is a device that maintains a strong mechanical connection between two shafts. It transfers motion from one shaft to another, at all loads and misalignments. Unlike a conventional linkage, a shaft coupling isn’t designed to allow relative motion between the two shafts. Couplings often serve several purposes in a machine, but their primary use is torque and power transmission.
Functions that control the flow of another function
One of the simplest programming constructs is a function that controls the flow of another function. A function can take an argument and return a different value, but it must be ready to return before it can pass that value to another function. To do this, you can use the goto statement and the if statement. Another way to control flow is to use a conditional statement.
Criteria for selecting a coupling
There are several important factors to consider when choosing the right coupling. One of the most important factors is coupling stiffness, which depends on the material used and the shape. The stiffness of a coupling determines its ability to resist elastic deformation. A stiff coupling is desirable for certain types of applications, but it’s undesirable for others. Stiffness can reduce the performance of a system if there’s too much inertia. To avoid this, ensure that the coupling you choose is within the recommended limits.
The size of a coupling is also important. Different coupling types can accommodate different shaft sizes and shapes. Some couplings have special features, such as braking and shear pin protection. When choosing a coupling, you should also consider the type of driven equipment. If you need to connect a high-torque motor, for example, you’ll want to choose a gear coupling. Likewise, a high-speed machine may require a disc coupling.
Another factor to consider when selecting a coupling is the torque rating. Despite its importance, it’s often underestimated. The torque rating is defined as the torque of the coupling divided by its OD. In some cases, torque may fluctuate during a cycle, requiring a coupling with a higher torque rating.
Torsionally flexible couplings are also important to consider. Their design should be able to withstand the torque required during operation, as well as the required speed. The coupling should also have a high degree of torsional stiffness, as well as damping. Furthermore, a damping coupling can reduce the energy wasted through vibration.
The sizing of a coupling is also determined by the torque. Many engineers use torque to select the correct coupling size, but they also take into consideration torsional flexibility and torsional stiffness. For example, a shaft may be able to handle large torque without damaging the coupling, while a disk may be unable to handle large amounts of torque.
Besides torque, another important consideration in coupling selection is the cost. While a coupling may be cheaper, it may be less reliable or easier to maintain. Couplings that are difficult to service may not last as long. They may also require frequent maintenance. If that’s the case, consider purchasing a coupling with a low service factor.
There are many different types of couplings. Some require additional lubrication throughout their lifetime, while others are 100% lubrication-free. An example of a 100% lubrication-free coupling is the RBI flexible coupling from CZPT. This type of coupling can significantly reduce your total cost of ownership.
In addition to the above-mentioned benefits, elastomeric couplings are low-cost and need little maintenance. While they are often cheaper than metallic couplings, they also have excellent shock absorption and vibration dampening properties. However, they are susceptible to high temperatures. Also, they are difficult to balance as an assembly, and have limited overload torque capacity.
