V-belts and V-belt pulleys are basic components of belt drives and are used in many mechanical systems in the industrial sector. Belt drives transfer rotary motion, torque, and power from a drive element to a driven element. In contrast to toothed belt drives that transfer power with an interlocking mechanism, belt drives work in a friction-locking manner. It is characteristic of belt drives that they ensure efficient friction-based power transfer and a longer service life while simultaneously providing a simple bearing arrangement.
