- Help to maximize performance and increase the expected life of the machine
- Used to connect two shafts which are perfectly in axial alignment for transmitting power
- Compensates for angular, parallel, skewed and axial shaft offsets
Muff couplings consist of a hollow cylinder whose inner diameter is the same as that of the shaft. These are fitted over the ends of the two shafts by means of a gib-head key. The power is transmitted from one shaft to the other shaft by means of a key and a sleeve.
It is, therefore, necessary that all the elements must be strong enough to transmit the torque. Muff couplings are the simplest type of rigid coupling for transmitting high torques at high speeds where misalignment is neither present nor desired.
