There are 2 basic types of couplings: rigid and flexible. Which kind of coupling is installed on the shafts being connected will depend on the application.
RedVector's Mechanical Maintenance: Couplings Course addresses how different couplings attach to shafts. You will learn the factors that can increase wear, the lifespan of a coupling and the applications of different coupling types. This mechanical maintenance training course also outlines how to deal with misalignment issues and covers selecting a coupling for a shaft in the right manner.
