The coupling is used to connect the two shafts together. The two shafts cannot be separated when the machine is running. The two shafts can be separated only after the machine is stopped and the connection is disconnected.
Due to manufacturing and installation errors, deformation after load, and the influence of temperature changes on the two shafts connected by the coupling, the relative position of the two shafts will change, and strict alignment is often not guaranteed.According to the coupling's elastic element, whether it has the ability to compensate various relative displacements, that is, whether the coupling function can be maintained under the condition of relative displacement, and the purpose of the coupling, couplings can be divided into rigid couplings, Flexible coupling and safety coupling.
