Coupling - Uses

Uses

Shaft couplings are used in machinery for several purposes, the most common of which are the following.

• To provide for the connection of shafts of units that are manufactured separately such as a motor and generator and to provide for disconnection for repairs or alterations.
• To provide for misalignment of the shafts or to introduce mechanical flexibility.
• To reduce the transmission of shock loads from one shaft to another.
• To introduce protection against overloads.
• To alter the vibration characteristics of rotating units.
