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.

flexible coupling

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.

What are the key considerations for selecting a flexible coupling for high-speed applications?

When selecting a flexible coupling for high-speed applications, several critical considerations should be taken into account to ensure optimal performance and reliability:

  • Material and Design: Choose a flexible coupling made from high-quality materials that can withstand the high rotational speeds without experiencing excessive wear or fatigue. Consider designs that are specifically engineered for high-speed applications, ensuring they have the required torsional stiffness and damping characteristics.
  • Balance: Imbalance at high speeds can lead to vibration and reduce the lifespan of the coupling and connected components. Look for precision-balanced flexible couplings that minimize vibration and avoid any potential resonance issues at operating speeds.
  • Torsional Stiffness: In high-speed applications, torsional stiffness is crucial to maintaining accurate rotational timing and preventing torque losses. Choose a flexible coupling with adequate torsional stiffness to minimize angular deflection under load.
  • Dynamic Balancing: Dynamic balancing is essential for flexible couplings used in high-speed applications. A dynamically balanced coupling reduces vibrations caused by rotational imbalances, increasing the smoothness and stability of the system.
  • Temperature Resistance: High-speed operations can generate significant heat, so select a flexible coupling that can withstand the elevated temperatures without compromising its mechanical properties or causing premature failure.
  • Alignment and Runout Tolerance: Accurate alignment of the coupling with the shafts is crucial to prevent additional stress and vibration. Consider couplings with high runout tolerance and ease of alignment to facilitate proper installation.
  • Service Life and Maintenance: Evaluate the expected service life of the flexible coupling in high-speed applications. Low-maintenance couplings are desirable to reduce downtime and maintenance costs.
  • Application Specifics: Consider the specific requirements of the high-speed application, such as the magnitude of torque, axial movement, and the presence of shock loads. Choose a coupling that can handle these specific demands while maintaining performance at high speeds.
  • Compliance with Standards: Ensure that the selected flexible coupling complies with relevant industry standards and specifications, especially those related to high-speed performance and safety.

By carefully considering these key factors, engineers can choose a flexible coupling that meets the demands of high-speed applications, delivering reliable and efficient power transmission while minimizing the risk of premature wear, vibration, and downtime.

flexible coupling

Are there any limitations or disadvantages of using flexible couplings?

While flexible couplings offer numerous advantages, they do come with some limitations and disadvantages that should be considered when selecting them for specific applications. Here are some of the common limitations and disadvantages of using flexible couplings:

  • Torsional Stiffness: Flexible couplings provide some level of torsional flexibility, which is advantageous in many applications. However, in systems that require high precision and minimal angular deflection, the inherent flexibility of the coupling may not be suitable. In such cases, a rigid coupling may be more appropriate.
  • Limitation in High-Torque Applications: While some flexible couplings can handle moderate to high torque levels, they may not be as well-suited for extremely high-torque applications. In such cases, specialized couplings, such as gear couplings, may be required to handle the high torque demands.
  • Temperature Limitations: The performance of certain flexible coupling materials, especially elastomers and plastics, may be affected by extreme temperature conditions. High temperatures can lead to premature wear and reduced lifespan of the coupling, while low temperatures may result in reduced flexibility and potential brittleness.
  • Chemical Compatibility: Certain flexible coupling materials may not be compatible with certain chemicals or substances present in the application’s environment. Exposure to chemicals can cause degradation or corrosion of the coupling material, affecting its performance and lifespan.
  • Installation and Alignment: Flexible couplings require proper installation and alignment to function effectively. If not installed correctly, misalignment issues may persist, leading to premature wear and reduced performance. Aligning the shafts accurately can be time-consuming and may require specialized equipment and expertise.
  • Cost: In some cases, flexible couplings may be more expensive than rigid couplings due to their more complex design and use of specialized materials. However, the cost difference is often justified by the benefits they offer in terms of misalignment compensation and vibration damping.
  • Service Life: The service life of a flexible coupling can vary depending on the application’s conditions and the quality of the coupling. Regular maintenance and timely replacement of worn or damaged parts are essential to ensure the coupling’s longevity and prevent unexpected failures.

Despite these limitations, flexible couplings remain highly valuable components in a wide range of applications, providing efficient torque transmission and compensating for misalignment. Proper selection, installation, and maintenance can help mitigate many of the disadvantages associated with flexible couplings, ensuring their reliable and long-lasting performance in various mechanical systems.
