A transmission rubber V-belt is a flexible, looped component made primarily from rubber and reinforced with materials such as polyester or nylon. Its distinctive V-shaped cross-section allows for increased friction, which is crucial for effective power transfer between the pulleys it connects. Commonly used in a variety of machinery, including automobiles, industrial equipment, and appliances, V-belts are designed to transmit power from the engine or motor to other components, such as generators, pumps, and compressors.
