Description

[0002] Coupling refers to a device that connects two shafts or a shaft and a rotating part, rotates together during the transmission of motion and power, and does not separate under normal circumstances. Sometimes it is used as a safety device to prevent the connected parts from bearing excessive load, playing the role of overload protection.

The brake wheel has a spring washer on one side. By using the brake wheel coupling and matching the drum brake, the brake disc coupling and the matching disc brake are replaced. This braking method belongs to bilateral braking, and the brake wheel is subjected to two opposite radial forces that can be canceled out. The shaft connected to the brake wheel is not subjected to radial force and only to braking torque, avoiding the occurrence of shaft breakage. In the running mechanism and rotating mechanism of the crane, the required braking torque is small, and the brake and brake wheel are small in size. This comparative case is more suitable for miniaturization, avoiding the use of large-size disc brakes and brake disc couplings, and reducing costs. However, the brake wheel and the coupling are connected by bolts and nuts, and the nuts are prone to loosening from the surface of the bolts after a long time of operation with the brake wheel and the coupling, affecting the stability of the connection between the brake wheel and the coupling, and even causing accidents.
