1. The coupling function is used to connect the two shafts together. The two shafts cannot be separated when the machine is running. The two shafts can only be separated after the machine is stopped and the connection is disconnected. 2. The type of coupling The two shafts connected by the coupling will change the relative position of the two shafts due to manufacturing and installation errors, deformation after loading, and the influence of temperature changes. Strict alignment is often not guaranteed.According to whether the coupling has elastic elements, whether it has the ability to compensate various relative displacements, that is, whether it can maintain the connection function and the purpose of the coupling under the condition of relative displacement, the coupling can be divided into rigid couplings, Flexible coupling and safety coupling.Rigid coupling: It can only transmit motion and torque, without other functions including flange coupling, sleeve coupling, clamp coupling, etc...
