Coupling
From Wikipedia, the free encyclopedia
- This article describes a mechanical connection between two things. For other meanings, see Coupling (disambiguation).
Rotating coupling
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Unlike a clutch, couplings do not allow disconnection of shafts during operation.
-
- Rigid couplings
- are used when precise shaft alignment is required; shaft misalignment will affect the coupling's performance as well as its life.
- Flexible couplings
- are designed to transmit torque while permitting some radial and axial and angular misalignment. Flexible couplings can accommodate angular misalignment up to a few degrees and some parallel misalignment.
Coupling is also an aviation term for aircraft dynamic interactions where movements in one aircraft axis are coupled to another axis, for example: inertia coupling and roll-coupling.
