16 Coupling, Clutch, and Brake

Chapter Objectives

In this chapter, you will learn about:

Couplings and their applications
Clutches and their applications
Brakes and their applications
Braking systems

16.1 INTRODUCTION TO COUPLING

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:

Rigid
Flexible

16.2 RIGID COUPLING

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 ...
