Coupling performance requirements Sep 04, 2018

(1) can be moved. The mobility of the coupling is the ability to compensate for the relative displacement of the two-turn member.

The factors such as the manufacturing and installation error, the temperature change in operation and the deformation of the load in the connecting member are required for the mobility. 

(2) cushioning.

In the case of frequent load starting or changing of working load, the coupling should have the elastic element of buffering and damping to protect the original motive and the work machine from being damaged or not.

(3) Safe, reliable, with sufficient strength and service life. 

(4) Simple structure, installation and demolition, easy maintenance.
