Couplings
In power transmission, couplings are mechanical elements used to connect two drive elements together for the transfer of torque from one element to another. A coupling connects both elements, usually shafts, that are in rotational movement, while also allowing a certain degree of misalignment, end movement, or both.
Couplings can be either rigid or flexible. Rigid couplings are more commonly used when two shafts are co-axial, or lie on the same axis as each other. Flexible couplings are used where there is less chance of co-axiality or when shocks are likely to occur during transmission of torque.
In industrial machinery, couplings serve the following purposes:
- To connect two shafts of separately manufactured units, for example, a motor and a generator
- To also allow for disconnection of the shafts for maintenance or repair operations or replacement of parts
- To connect both the driving and the driven part
- Allow misalignment of the shafts and to reduce shock loads at the meeting point of both shafts
