Type characteristics of diaphragm coupling

　　The two shafts connected by the diaphragm coupling will change the relative position of the two shafts due to manufacturing and installation errors, deformation after load, and the influence of temperature changes, and it is often impossible to strictly align the two shafts.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 couplings and couplings.

　　Rigid coupling: It can only transmit motion and torque, and does not have other functions including flange coupling, sleeve coupling, clamp coupling, etc.

　　Flexible coupling: A flexible coupling without elastic elements can not only transmit motion and torque, but also has different degrees of axial, radial and angular compensation performance, including gear couplings, universal couplings Couplings, chain couplings, slider couplings, etc.

　　The flexible coupling with elastic elements can transmit motion and torque; it has different degrees of axial, radial and angular compensation performance; it also has different degrees of vibration reduction and buffering. The working performance of the transmission system includes various A flexible coupling with a non-metal elastic element and a flexible coupling with a metal elastic element. The structure of various elastic couplings is different, the difference is large, and the role in the transmission system is also different.
