Introduction of several types of couplings

The two shafts connected by the coupling, due to manufacturing and installation errors, deformation after load, and the influence of temperature changes, will cause changes in the relative position of the two shafts, and often cannot be strictly aligned.According to whether the coupling has elastic parts, 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 premise of relative displacement, the coupling can be divided into rigid couplings, Flexible coupling andCoupling.The main types and characteristics of the coupling and the remarks on the role of the type in the transmission system.

Flexible coupling: A flexible coupling without elastic elements can not only transmit motion and torque, but also have different degrees of axial, radial and angular compensation functions including gear couplings and 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 functions; it also has different degrees of vibration reduction, buffering, and the working functions of the transmission system, including Various non-metal elastic element flexible couplings and metal elastic element flexible couplings have different structures and great differences, and their roles in the transmission system are also different.

Rigid coupling: It can only transmit motion and torque. There are several failures of drum gear couplings and their causes. It does not have other functions including flange coupling, sleeve coupling, and clamp coupling Etc., the calculation of the coupling and the function of the two types.
