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 Motor Couplings Compensate for Angular, Parallel, and Axial Misalignments?
Yes, motor couplings are designed to compensate for different types of misalignments, including angular, parallel, and axial misalignments. The ability to accommodate misalignment is a key feature of motor couplings, and various coupling types offer different levels of misalignment compensation:
1. Angular Misalignment:
Angular misalignment occurs when the motor and driven equipment shafts are not perfectly aligned in the same plane, causing an angle between them. Motor couplings, especially flexible couplings, can effectively compensate for angular misalignment. Flexible couplings like jaw couplings, beam couplings, and oldham couplings can tolerate angular misalignment to a certain extent while transmitting torque smoothly.
2. Parallel Misalignment:
Parallel misalignment happens when the motor and driven equipment shafts are not perfectly aligned along their axis, leading to offset displacement. Flexible couplings, such as bellows couplings and disc couplings, are well-suited to accommodate parallel misalignment. These couplings can maintain good misalignment tolerance while providing high torsional stiffness for efficient torque transmission.
3. Axial Misalignment:
Axial misalignment occurs when there is a linear offset between the motor and driven equipment shafts along the axis. For some flexible couplings, a limited amount of axial misalignment can be tolerated. However, specific coupling types, such as self-aligning ball bearing couplings, are more suitable for handling higher levels of axial misalignment.
It is important to note that while motor couplings can compensate for misalignment, they have their limits. Excessive misalignment can lead to premature wear, reduced efficiency, and potential coupling failure. Proper alignment during installation and regular maintenance are essential to ensure the coupling’s misalignment compensation remains effective over time.
When selecting a motor coupling, consider the type and amount of misalignment expected in your application. Choose a coupling that offers the required level of misalignment compensation, ensuring smooth power transmission and extending the lifespan of the coupling and connected components.

How Does a Flexible Motor Coupling Differ from a Rigid Motor Coupling?
Flexible motor couplings and rigid motor couplings are two distinct types of couplings used to connect motors to driven equipment. They differ significantly in their design, function, and applications:
Flexible Motor Coupling:
A flexible motor coupling is designed to accommodate misalignment between the motor shaft and the driven equipment shaft. It uses flexible elements, such as elastomeric materials, to provide some degree of flexibility and damping. The key differences are:
- Misalignment Compensation: Flexible couplings can handle both angular and parallel misalignment between the motor and driven equipment shafts. This flexibility reduces stress on bearings and allows for a smoother transmission of torque.
- Shock Absorption: The elastomeric elements in flexible couplings can absorb and dampen vibrations and shock loads, protecting the motor and driven equipment from damage.
- Applications: Flexible couplings are commonly used in applications where misalignment is expected, such as pumps, compressors, conveyors, and machine tools.
Rigid Motor Coupling:
A rigid motor coupling provides a solid and inflexible connection between the motor shaft and the driven equipment shaft. It does not allow any misalignment and offers a direct torque transmission path. The key differences are:
- No Misalignment Compensation: Rigid couplings do not accommodate misalignment between the motor and driven equipment shafts. Proper alignment is critical for their efficient operation.
- Stiffness: Rigid couplings offer high torsional stiffness, maintaining precise alignment between the shafts and enabling accurate torque transmission.
- Applications: Rigid couplings are used in applications where precise alignment is required, such as high-precision machine tools, robotics, and applications with low or negligible misalignment.
The choice between a flexible motor coupling and a rigid motor coupling depends on the specific requirements of the application. Flexible couplings are preferred when misalignment is expected, while rigid couplings are suitable for applications where precise alignment and direct torque transmission are essential for the system’s performance.
