V-belt transmission operates on the principle of friction between the belt and pulleys. When the prime mover, such as an electric motor, turns the driving pulley, the belt rotates around it. Due to the wedge shape of the V-belt, a significant amount of friction is generated, allowing the belt to transmit power to the driven pulley. This system can effectively transfer rotational motion from one axis to another, making it invaluable in various mechanical setups.

An alternator belt is a rubber belt that connects the alternator to the engine crankshaft. In modern vehicles, it typically functions as a serpentine belt, which drives not only the alternator but also other vital systems, including the power steering pump, water pump, and air conditioning compressor. When the alternator belt wears out, it can lead to diminished electrical performance, battery issues, and even overheating if the water pump is affected.
