a toothed flat belt drive

V-belts are essential components in belt drive systems, typically used to transmit power from one unit to another through rotational motion. The V shape of the belt allows it to fit snugly into the corresponding grooves of pulleys, providing a high degree of surface contact and enhancing grip. The rough top surface of certain V-belts is designed to improve the frictional contact with the items they transport. This rough texture is particularly beneficial in applications where a secure grasp on the material is necessary.

Another type of belt found in some vehicles is the timing belt. Unlike the serpentine belt, the timing belt is critical for synchronizing the rotation of the crankshaft and camshaft. This ensures that the engine's valves open and close at the correct times in relation to the position of the pistons. Generally made from a rubber material reinforced with fiber, the timing belt is subject to significant stress due to high temperatures and mechanical strain.
