crane coupling

Crane couplings are mainly used on all kinds of Overhead crane and Gantry crane, and are important transmission connecting parts of cranes. The crane coupling works by transmitting torque between the driving shaft and the driven shaft. Generally speaking, the power mechanism needs to be connected to the working mechanism through a coupling. In addition to the general torque transmission function, some crane couplings with high performance requirements also have buffering and vibration reduction functions.

crane coupling details

Crane coupling customized according to your needs.

The crane coupling plays a compensating role during crane operation. When the crane is running, all components are subjected to force, which can easily deform, especially the main beam of the crane. Once the main beam is deformed, it will directly affect the normal operation of the crane operating mechanism. When the main beam is in a deformed state, in order to ensure the normal operation of the operating mechanisms of various components of the crane and compensate for errors during the manufacturing and installation process of the crane, compensation is generally provided for the crane equipment. This type of coupling includes cross couplings, gear couplings, etc.

The main material of the crane coupling is forged by heating 45 # and 42CRMO. The teeth of the crane coupling need to undergo high-frequency quenching, with a quenching hardness of HRC38-55, making the coupling more wear-resistant and extending the service life of the crane coupling.
