Coupling bolt backrest pin

The function of the coupling bolt backrest pin:

The coupling bolt backrest pin is a component that connects the two shafts axially and transmits torque and motion. It has the ability to compensate for the deviation of the two shafts. In order to reduce the vibration of the mechanical transmission system and reduce the impact peak load, the coupling should also Has the cushioning and shock absorption performance.The coupling sometimes also has an overload protection function.  

Selection principle of coupling bolt backrest pin: 

Alignment: For good alignment, choose a rigid coupling, and when compensation is needed, choose a flexible coupling; 

Assembly and disassembly: Considering the convenience of assembly and disassembly, choose a coupling that can directly move radially; 

Environment: If working at high temperatures, couplings with non-metallic components are not available; 

Cost: Under the same conditions, try to choose a coupling with a low price and simple maintenance.
