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 CZPT 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.

How does a flexible coupling handle angular, parallel, and axial misalignment?
A flexible coupling is designed to accommodate various types of misalignment between two rotating shafts: angular misalignment, parallel misalignment, and axial misalignment. The flexibility of the coupling allows it to maintain a connection between the shafts while compensating for these misalignment types. Here’s how a flexible coupling handles each type of misalignment:
- Angular Misalignment: Angular misalignment occurs when the axes of the two shafts are not collinear and form an angle with each other. Flexible couplings can handle angular misalignment by incorporating an element that can flex and bend. One common design is the “spider” or “jaw” element, which consists of elastomeric materials. As the shafts are misaligned, the elastomeric element can deform slightly, allowing the coupling to accommodate the angular offset between the shafts while still transmitting torque.
- Parallel Misalignment: Parallel misalignment, also known as offset misalignment, occurs when the axes of the two shafts are parallel but not perfectly aligned with each other. Flexible couplings can handle parallel misalignment through the same elastomeric element. The flexible nature of the element enables it to shift and adjust to the offset between the shafts, ensuring continuous power transmission while minimizing additional stresses on the machinery.
- Axial Misalignment: Axial misalignment, also called end-play misalignment, occurs when the two shafts move closer together or farther apart along their common axis. Flexible couplings can handle axial misalignment through specific designs that allow limited axial movement. For instance, some couplings use slotted holes or a floating member that permits axial displacement while maintaining the connection between the shafts.
By providing the capability to handle angular, parallel, and axial misalignment, flexible couplings offer several advantages for power transmission systems:
- They help to prevent premature wear and damage to the connected equipment, reducing maintenance and replacement costs.
- They minimize vibration and shock loads, enhancing the overall smoothness and reliability of the machinery.
- They reduce the risk of equipment failure due to misalignment-induced stresses, improving the system’s operational life.
- They allow for easier installation and alignment adjustments, saving time and effort during setup and maintenance.
Overall, flexible couplings play a crucial role in handling misalignment and ensuring efficient power transmission in various industrial applications.

What are the advantages of using flexible couplings in mechanical systems?
Flexible couplings offer several advantages in mechanical systems, making them essential components in various applications. Here are the key advantages of using flexible couplings:
- Bù sai lệch: One of the primary advantages of flexible couplings is their ability to compensate for shaft misalignment. In mechanical systems, misalignment can occur due to various factors such as installation errors, thermal expansion, or shaft deflection. Flexible couplings can accommodate angular, parallel, and axial misalignment, ensuring smooth power transmission and reducing stress on the connected equipment and shafts.
- Giảm chấn rung động: Flexible couplings act as damping elements, absorbing and dissipating vibrations and shocks generated during operation. This feature helps to reduce noise, protect the equipment from excessive wear, and enhance overall system reliability and performance.
- Torsional Flexibility: Flexible couplings provide torsional flexibility, allowing them to handle slight angular and axial deflections. This capability protects the equipment from sudden torque fluctuations, shock loads, and torque spikes, ensuring smoother operation and preventing damage to the machinery.
- Overload Protection: In case of sudden overloads or torque spikes, flexible couplings can absorb and distribute the excess torque, protecting the connected equipment and drivetrain from damage. This overload protection feature prevents unexpected failures and reduces downtime in critical applications.
- Reduce Wear and Maintenance: By compensating for misalignment and damping vibrations, flexible couplings help reduce wear on the connected equipment, bearings, and seals. This results in extended component life and reduced maintenance requirements, leading to cost savings and improved system reliability.
- Bù trừ cho sự giãn nở nhiệt: In systems exposed to temperature variations, flexible couplings can compensate for thermal expansion and contraction, maintaining proper alignment and preventing binding or excessive stress on the equipment during temperature changes.
- Electric Isolation: Some types of flexible couplings, such as disc couplings, offer electrical isolation between shafts. This feature is beneficial in applications where galvanic corrosion or electrical interference between connected components needs to be minimized.
- Space and Weight Savings: Flexible couplings often have compact designs and low inertia, which is advantageous in applications with space constraints and where minimizing weight is crucial for performance and efficiency.
- Cost-Effectiveness: Flexible couplings are generally cost-effective solutions for power transmission and motion control, especially when compared to more complex and expensive coupling types. Their relatively simple design and ease of installation contribute to cost savings.
In summary, flexible couplings play a vital role in mechanical systems by providing misalignment compensation, vibration damping, overload protection, and torsional flexibility. These advantages lead to improved system performance, reduced wear and maintenance, and enhanced equipment reliability, making flexible couplings a preferred choice in various industrial, automotive, marine, and aerospace applications.
