Industrial equipment is commonly powered by belt drives because they are flexible, relatively inexpensive, simple to install and maintain, and require a minimal amount of space. In addition, belt-driven equipment parts are easy to obtain and replace, a fact that helps reduce downtime spent on repairs.
Industrial belt drives are used to transfer torque and aid in speed changes from one shaft to a another shaft. In all applications, the drive consists of one or more belts and a sheave/pulley relationship. Changing the diameter of the driven sheave/pulley alters the ratio and causes a change in the speed.
Drive belts are grouped into three basic classifications according to their cross-sectional design: v (vee) or wedge, flat, and synchronous (toothed or timing). Each type of belt requires a different type of pulley system. V-style belts match with a grooved pulley or sheave, flat style belts use a drum style pulley, and toothed belts match with a toothed pulley or sprocket.
Belt drives have following advantages over other drive types such as close-coupled, roller chain, and gear drives:
- Economical to install and maintain
- Reliable and trouble-free
- Simple to design
- Easy to install
- No lubrication is required
- Work in a variety of applications
- Can be adjusted for any speed requirement
- Quiet and operate smoothly
- Pulleys are less expensive than chain sprockets
- Long sheave/pulley life
- Can act like a clutch and prevent catastrophic failure
