Type of coupling

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 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 * coupling.The main types and characteristics of the coupling and its role in the role of the remarks in the transmission system
Rigid couplings can only transmit motion and torque, without other functions including flange couplings, sleeve couplings, clamp couplings, etc.
Flexible couplings Flexible couplings without elastic elements can not only transmit motion and torque, but also have different degrees of axial, radial and angular compensation performance, including gear couplings, universal couplings , Chain coupling, slider coupling, 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 damping and buffering effects to improve the working performance of the transmission system, including Various flexible couplings with non-metal elastic elements and flexible couplings with metal elastic elements. The structure of various elastic couplings is different, the difference is large, and the role in the transmission system is also different.
*Coupling transfers movement and torque, overload* protection.Flexible* couplings also have different levels of compensation performance, including pin type, friction type, magnetic powder type, centrifugal type, hydraulic type, etc.* coupling
