In industrial doors, the coupling serves to connect two shafts or a shaft with a rotating component. It rotates together during the process of transmitting motion and power, and under normal circumstances, it does not disengage. Sometimes, it is also used as a safety device to prevent the connected components from bearing excessive loads, thereby providing overload protection.
