Q:

What are the main types of coupling?

A:

Quick Answer

The main types of coupling include rigid sleeve, flanged, jaw and spider coupling. Rigid sleeve and flanged coupling are generally known as rigid coupling, while jaw and spider coupling fall under flexible coupling.

Full Answer

Rigid coupling is simple, cheap and easy to design compared to flexible coupling. Rigid coupling, however, is susceptible to bending and overloading due to misalignment.

In flexible coupling, misalignment is desirable rather than a disadvantage. This type of coupling allows for radial, axial or angular alignment of shafts and is suitable for complex designs. Flexible coupling is expensive and relatively difficult to construct.

The choice of the right type of coupling mainly depends on the specific design of the location.
