Friction Forced

A friction-forced power transmission belt, also known as a V-belt, has a trapezoidal cross-section, commonly used to transfer power between rotating shafts through friction with pulleys. Its design enhances friction by fitting into V-shaped grooves on the pulleys, making it suitable for moderate torque applications in vehicles, industrial machinery, and other systems.
