pu timing belt

The primary function of the drive belt is to transfer power from the engine’s crankshaft to various accessories, enabling them to operate. For instance, when the engine runs, it rotates the crankshaft, which in turn causes the drive belt to spin. This motion activates the accessories connected to the belt. Unlike older cars that used several different belts to connect individual accessories, most modern vehicles utilize a single serpentine belt, which is more efficient and easier to replace.

The operation of cogged belts is primarily based on the interlocking design of their teeth. When the belt is driven by a pulley, the teeth fit snugly into the grooves of the pulley, ensuring that there is minimal slippage. This characteristic offers a high degree of accuracy, making cogged belts especially suitable for applications where precise timing is crucial, such as in engine timing systems, where the belt must synchronize the crankshaft and camshaft rotations.
