Question

List a suitable coupling for each of the following applications. 1) Must be capable of handling large angular and parallel misalignments. 2) Must be able to hande high torque, absorb shock and torsional vibrations, parallel and angular misalignment and be a non-lubricated type. 3) Low/medium torque transmission, low cost design, absorb torsional shocks, handle small parallel and angular misalignment (up to 0.5mm parallel and 1.7 degrees angular). Must be Fail Safe.

Answer 1

1. Disc coupling

They are capable of handling high angular and parallel misalignment

2. Diaphragm Coupling

It is a non lubricating coupling, which has high torque transmission capacity

Parallel and angular misalignment

It absorb shock and vibrations.

3. Roller Chain Coupling

It is a lubricating coupling, which is cost effective in design.

It can handle parallel and angular misalignment and

It can abosrbs torsional shocks.
