The function of the coupling is as follows:
1. It connects the prime mover and the shaft of the working machine and transmits the torque.
2. It can properly compensate the radial, axial and angular errors of the two shafts caused by factors such as manufacturing and installation.
3. Safety coupling When overload occurs, the coupling slips or the pin is disconnected to protect the working machine.
4. The elastic coupling also has the functions of buffering, damping and improving the dynamic performance of the shafting.
