What is Coupling? Types of Shaft Couplings

This article describes what is a coupling, types of couplings, rigid couplings, flexible couplings, universal couplings, Hookes coupling, Pin Bush Coupling, Flanged Coupling etc. Couplings are mechanical elements that ‘couples’ two drive elements which enables motion to be transferred from one element to another. The drive elements are normally shafts. We tend to see lot of applications of the couplings mainly in the automobiles, for example the drive shaft which connects the engine and the rear axle in a bus or any automobile is connected by means of a universal joint.
