Coupling Information:

The function of the coupling is to connect the two shafts (the driving shaft and the driven shaft) in different mechanisms to make them rotate together and transmit torque. Some couplings also have buffering and vibration reduction.
According to different working conditions, the coupling needs to have the following properties:
(1) Portability. The mobility of the coupling refers to the ability to compensate for the relative displacement of the two rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation, and deformation under load all place requirements on portability. Movable performance compensates or relieves additional loads between shafts, bearings, couplings and other components due to relative displacement between rotating components.
(2) Buffering. For occasions where frequent load starts or working load changes, the coupling needs to have elastic elements for buffering and vibration damping to protect the prime mover and the working machine from being damaged or not damaged.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, convenient assembly and disassembly and maintenance. Couplings are also called couplings. A mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect shafts and other parts
