Answer 1

Explanation:

Coupling:

Coupling is a device that is used to connect two shafts permanently.

Rigid Coupling

Flexible Coupling

This type of coupling requires the perfect alignment of the shafts to be joined.

This type of coupling is used where the shafts are –

Additional Information

Sleeve / Muff Coupling:

F1 S.S Madhu 17.02.20 D1

This coupling consists of cast iron sleeves that are fitted over both shafts ends by means of keys.
Simple in design and manufacture.
Dis-assembly is difficult.
Used with small diameter shafts only.

Flange Coupling:

It consists of two cast-iron flanges.
The flanges are keyed to the shaft ends and then bolted together to make a joint.
The coupling is widely used and is capable of transmitting large torques.
Design is simple, easy to assemble and dis-assemble and the cost is low just requires proper alignment.

Oldham Coupling:

This is used to join two laterally non-aligned shafts which are parallel.
It consists of two flanges with slots and a central floating part is held by means of a pin passing through the flanges.

Universal Joint:

It permits substantial angular misalignment of the shafts having intersecting axes.
A common example is the joint used at the end of the drive shaft on rear-wheel-drive automobiles.
