The Maintenance-Free Universal Joint coupling belongs to the category of general mechanical parts, and is a mechanical part used to connect two shafts in different mechanisms to rotate together to transmit torque. In high-speed and heavy-load power transmission, some universal joint couplings also have the function of buffering, damping and improving the dynamic performance of the shafting. The universal joint coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.

The model of universal joint coupling is roughly selected according to the transmitted torque, speed, allowable deviation, etc. The physical objects required by different environments are different. When choosing a universal joint coupling, choose the appropriate universal joint coupling model under different conditions.

Appropriate universal joint coupling model selection is conducive to the use of the machine and improve work efficiency.

1. The shaft system connected by the universal joint coupling and its operation. For the connection shaft system with large mass and large moment of inertia, and frequent starting, speed change or reverse rotation, it should be considered to select a spring-elastic pin universal joint coupling that can withstand large instantaneous overloads and cushion vibration.

2. The speed of the working universal joint coupling is high or low. For the two-axis connection that requires high-speed operation, the structure of the universal joint coupling should be considered to have high balance accuracy characteristics to eliminate vibration and noise caused by centrifugal force, and increase The wear and heat of the related drum-shaped gear universal joint coupling reduce the transmission quality and service life, and the diaphragm universal joint coupling has better adaptability to high-speed operation.

3. The universal joint coupling device characteristics of the prime mover and the working universal joint coupling. The type of prime mover is different. Some of its output power and speed are stable, and some are shocked or even strong. This will directly affect the choice of universal joint coupling type and is one of the primary basis for selection. For a stable load and to discuss the development of the industry, you can choose a rigid elastic pin universal joint coupling, otherwise you should choose an elastic elastic pin universal joint coupling, TL type elastic sleeve pin U-Joint With Pressed Bearings coupling Device.
