Shaft couplings have many types with different functions so that how to choose a suitable shaft coupling is a problem for the user. Some shaft couplings have been standardized. When selecting, you should first select the appropriate type according to the work requirements. Then calculate the torque and speed according to the diameter of the shaft. Next find the applicable model from the relevant manual. Finally, make the necessary check calculations for some key parts.

A shaft coupling is a device used to join two pieces of rotating equipment or shaft for the purpose of transmitting power from one shaft to another shaft. Here, shaft couplings have many types with different specifications as well as functions. You may wonder how many types of shaft couplings are there and how can we choose a suitable shaft coupling.
