J. Couplings

When (1) the transmission shaft is too long that causes difficulty for design and installation, (2) the shaft is separated as two non-colinear segments, (3) the shaft is operating with two rotational speeds, or (4) the driven shaft is expected to be able to be isolated, stopped, or connected to the driving shaft at any time, the couplings are usually used for facilitating such transmission. Broadly speaking, coupling is a device used to join two moving members. The most common utilization of couplings is the one that joins the ends of the shafts of the motor and driven mechanism, in which the motor power can be transferred into the driven mechanism. Also, it is frequently adopted for the motion transformation through the power devices (e.g., motors or engines), speed reducers, and the driven mechanisms. Unlike other mechanisms, the couplings are able to deliver motion based on very few parts. Hence it has the features of simple design and ease for replacement.
