Concept explainers

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.

Why are these important to consider? Please explain each
These are Considerations in Designing a Friction Clutch. Can you explain these conditions?The following considerations must be kept in mind while designing a friction clutch.1. The suitable material forming the contact surfaces should be selected.2. The moving parts of the clutch should have low weight in order to minimise the inertia load,especially in high speed service.3. The clutch should not require any external force to maintain contact of the friction surfaces.4. The provision for taking up wear of the contact surfaces must be provided.5. The clutch should have provision for facilitating repairs.6. The clutch should have provision for carrying away the heat generated at the contactsurfaces.7. The projecting parts of the clutch should be covered by guard
