In a rigid coupling, the torque is transmitted from one half of the coupling to the other through the bolts and in this arrangement shafts need be aligned very well. However, in the bushed coupling the rubber bushings over the pins (bolts) (as shown in Figure 16.2) provide, flexibility and can accommodate, some misalignment. Because of…

Rigid couplings are designed to draw two shafts together tightly so that no relative motion can occur between them. This design is used for some special kinds of equipment in which precise alignment of two shafts is required. In such cases, the coupling must be capable of transmitting the torque in the shafts. Rigid couplings…

The term coupling is a device used to connect two shafts together at their ends for transmitting the power. There are a number of coupling devices used to couple two shafts but in this chapter only few important couplings have been introduced for understanding of the students. There are two general types of couplings:
