6 Belt Drives

A mechanical drive, sometimes called a power transmission, is usually used to transmit power and motion from one rotational element to another. Mechanical drives include belt drives, chain drives, gear drives, wormgear drives and so on. They can be broadly classified as flexible and non‐flexible or rigid power transmission drives. In a flexible drive, there is an intermediate, flexible element such as a belt or a chain between the driving and driven shafts. The rotary motion of the driving shaft is first converted into translatory motion of the belt or chain and then converted back into the rotary motion of the driven shaft. In a rigid drive, such as in a gear drive, the rotary motion of the driving shaft is directly converted into the rotary motion of the driven shaft by the direct contact of pinion and gear. This chapter will discuss in detail the features, as well as analysis and design of belt drives. The analysis and design of other mechanical drives will be introduced in the succeeding chapters.
