Sleeve coupling

A sleeve coupling is a basic type of

coupling A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end mov ...

is finished to the required tolerance based on the shaft size. Based on the usage of the coupling a keyway is made in the bore in order to transmit the

torque In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of th ...

by means of the key. Two threaded holes are provided in order to lock the coupling in position. Sleeve couplings are also known as box couplings. In this case shaft ends are coupled together and abutted against each other which are enveloped by ''muff'' or ''sleeve''. A gib head sunk keys hold the two shafts and sleeve together Rotating shaft couplings {{Mech-engineering-stub
