Question

What is the difference between clutch and coupling?

Answer 1

Clutch are used to obtained temporary connection between driver and driven shaft. Coupling is used to obtained permanent connection between driver and driven shaft. ... Coupling are used in application where driven machine required continuous service. Clutchesare used to transmit power betweentwo co-linear shafts.

Answer 2

Clutch and coupling

Explanation:

A clutch is a mechanical device which engages and disengages power transmission especially from driving shaft to driven shaft. In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. So, clutch provides a temporary connection between driver and driven shaft.

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded. Coupling provides a permanent connection between the two shafts.
