Crane Coupling

Coupling is a mechanical part used to connect two shafts so that they can rotate together and transmit motion and torque. In the high-speed and heavy-duty power transmission, the coupling also has the function of buffering, damping and improving the dynamic performance of the shafting. The coupling is composed of left and right parts, which are respectively connected with the driving shaft and the driven shaft (used to connect power sources such as reducers and motors). The general power machine is mostly connected with the working machine by means of a coupling.


Couplings are divided into flexible couplings and rigid couplings:

1.Rigid coupling: has simple structure, can't compensate the relative deviation of the two shafts; it can be used for the two shafts to ensure strict centering and stable load.

2.Flexible coupling: It can compensate the relative deviation of the two shafts, which is used at the place where the two shafts cannot be strictly aligned. The flexible coupling without elastic components has large bearing capacity and can not mitigate impact and absorb vibration. Metal elastic element flexible coupling has large bearing capacity and can mitigate impact and absorb vibration. Flexible coupling with non-metallic elastic elements has small bearing capacity and can mitigate impact and absorb vibration.

Couplings are widely used, and couplings are almost always needed wherever there is a need to connect the transmission. Between the reducer and reducer, between the reducer and motor, between the reducer and equipment, between the motor and equipment, etc.
