A coupling is a basic mechanical part that connects two shafts together, accurately transmits power from the active side to the driven side, and absorbs installation errors, misalignment, etc. of the two shafts.

The explanation of a coupling in the mechanical industry is "a part that connects two shafts together", generally called "coupling", "coupling" or "joint". Let's take a closer look at what a coupling is and what types of couplings there are.

A coupling is a device used to connect the two ends of two shafts together to transmit power. The main purpose of a coupling is to connect two rotating devices while allowing a certain degree of misalignment or end movement, or both.

In a more general context, a coupling can also be a mechanical device used to connect the ends of adjacent parts or objects.

Couplings generally do not allow the shaft to be disconnected during operation, however, there are torque-limited couplings that slip or disconnect when a certain torque limit is exceeded.

The main purpose of a coupling is to connect two rotating devices while allowing a certain degree of misalignment or end movement, or both. Selecting, installing and maintaining couplings can reduce maintenance time and costs.
