Working Principle

fluid coupling

The working principle of a coupling is to connect two shafts to transmit power and rotational motion, while allowing for a certain degree of axial displacement, angular deviation, and vibration absorption. The following are the working principles of common couplings:

Elastic Coupling

Elastic coupling uses elastic components (such as elastic sleeves, elastic gears, etc.) to connect two shafts. When the shaft undergoes axial displacement, angular deviation, or vibration, elastic components can bend, twist, or compress to absorb asymmetric loads and vibrations, protecting the shaft and related equipment.

Gear Coupling

A gear coupling uses a gear pair to transmit power to another shaft. The meshing between gears enables the two shafts to rotate synchronously and transmit torque. Gear couplings are typically used for high torque transmission and precise rotation applications.

Locking Coupling

The locking coupling tightly connects the two shafts together through fastening devices (such as bolts, locking sleeves, etc.). This type of coupling has a simple and compact design, suitable for applications that require rigid connections and high precision.

Fluid Coupling

A fluid coupling uses a liquid (usually a liquid coupling agent) to transmit power and rotational motion. The liquid coupling achieves torque transmission through the viscosity and rotational inertia of the liquid, while also absorbing shock and vibration.

How to

Choose Coupling

Choosing a suitable coupling is the key to ensuring the smooth operation of the transmission system. Here are some guidelines to help you make wise decisions when choosing a coupling:coupling for motor

  1. Consider application requirements: Firstly, understand your application requirements. Determine the required torque transmission range, speed range, and working environment conditions. This will help narrow the selection range and ensure that the coupling can meet your specific requirements.
  2. Consider transmission type: Select the coupling based on the transmission type. For example, chain drives are typically suitable for applications with high torque and lower rotational speeds, while elastic couplings are suitable for situations that require shock absorption and vibration absorption.
  3. Consider space limitations: Assess your installation space limitations. Different types of couplings vary in size and appearance, so ensure that the selected coupling is suitable for your installation requirements.
  4. Consider alignment ability: Alignment ability is the ability of the coupling to handle axis and angle deviations. Select appropriate alignment capabilities according to the application needs to ensure that the coupling can adapt to the relative motion of the shaft.
  5. Consider durability and maintenance: Evaluate the durability and maintenance of the coupling. Choosing a well designed and manufactured coupling can provide reliable performance and reduce maintenance work.
  6. Consulting experts: If you are confused about choosing the appropriate coupling, do not hesitate to seek professional advice. Communicate with suppliers or professional engineers, who can provide targeted suggestions based on your application needs.
  7. Consider cost-effectiveness: Finally, consider cost-effectiveness comprehensively. Ensure that the selected coupling matches its performance and quality while also meeting your budget requirements.

In summary, selecting a suitable coupling requires comprehensive consideration of factors such as application requirements, transmission type, space limitations, alignment ability, durability, and maintenance. By carefully evaluating these factors and making wise choices based on professional advice, you will be able to choose the coupling that is most suitable for your application.



A coupling is a mechanical device used to connect two shafts to transmit power or rotational motion. They are widely used in various industries and applications. The following are some common applications of couplings:

fluid coupling

  • Mechanical equipment transmission: Couplings are used to transmit power and rotational motion, transferring the rotation of electric motors or engines to other rotating equipment, such as pumps, fans, compressors, mixers, conveyors, etc.
  • Machine tool and tool transmission: Couplings are used in machine tools and tools to transmit power and rotational motion, such as milling machines, lathes, drilling machines, grinders, etc.
  • Transportation equipment: Couplings are used for power transmission and drive of transportation equipment such as cars, trains, ships, etc.
  • Heavy machinery: Couplings play an important role in the field of heavy machinery, such as cranes, excavators, loaders, bulldozers, etc.
  • Petroleum and chemical industry: Couplings are used in petroleum and chemical equipment, such as pumps, compressors, mixers, etc.
  • Wind and solar power generation: Couplings are used in wind turbines and solar power generation equipment to convert wind or solar energy into electricity.
  • Manufacturing and industrial automation: Couplings are widely used in manufacturing and industrial automation to transmit power and rotational motion, such as production lines, assembly equipment, robots, etc.
  • Agriculture and agricultural machinery: Couplings are used in the agricultural field to transmit power and rotational motion, such as agricultural vehicles, harvesters, sprinkler equipment, etc.

These are just some common application areas for couplings. Due to the wide applicability and flexibility of couplings, they can be used in almost any application that requires the transmission of power and rotational motion.
