alternator fan belt

The operation of a toothed belt involves the interaction of these teeth with the grooves on the pulleys. When the driving pulley rotates, the belt moves in unison, causing the driven pulley to rotate at a specific ratio, which is determined by the size of the pulleys and the number of teeth on the belt. This precise coordination allows for accurate synchronization in applications like engine timing, where even a slight delay can result in serious mechanical issues.

A toothed belt is a reinforced rubber belt that has teeth or cogs on its inner surface. It is designed to fit into corresponding grooves on the pulley systems of an engine. The primary function of the toothed belt is to synchronize the rotation of the crankshaft and camshaft. This synchronization is crucial because it governs the timing of the opening and closing of engine valves in relation to the movement of the pistons. This precise coordination allows the engine to operate smoothly and efficiently, directly impacting performance and fuel efficiency.
