Couplings create connections between drive shafts and driven shafts in order to transmit rotary motion and torque. For example, they are used to combine the shafts of motors and transmissions into a single drive unit.
Alongside the primary purpose of transmitting torque, couplings also carry out other important tasks:
- Compensating for shaft offsets and misalignments
- Absorbing runout errors and axial motions
- Damping vibrations and shocks
Couplings are used in a very wide range of applications. The spectrum ranges from simple drives to complex control, regulation and measurement applications
