power transmission belt

A timing belt is a looped belt made of reinforced rubber or urethane with teeth that mesh perfectly with the teeth on the gears of the pulleys. The primary function of the timing belt is to synchronize the rotation of the crankshaft and camshaft in an internal combustion engine, ensuring that the engine's valves open and close in time with the movement of the pistons. This synchronization is critical for optimal engine performance and efficiency, preventing any potential interference that could lead to engine damage.

The design of poly V-belts is characterized by several small, parallel grooves running along the length of the belt. This ribbed structure increases the surface area in contact with the pulleys, enhancing grip and thereby allowing for more efficient power transfer. The belts are typically made from high-quality rubber compounds reinforced with synthetic fibers, which offer exceptional strength and flexibility. Additionally, the compact design of poly V-belts enables them to operate effectively in tight spaces, which is a common requirement in modern machinery.
