The timing belt is a very important part of the automobile. People must often check whether it is damaged, worn or loose. Any damage or defect of the timing belt will eventually lead to serious and more expensive damage to the engine. The huge torque and distortion of timing belt will lead to belt fracture, local extrusion into blocks, over stretching, and even cracks. Therefore, people pay great attention to the maintenance of timing system.

The steel wire rope for PU synchronous belt has the following characteristics:

(1) Accurate transmission, no sliding when working, with constant transmission ratio;

(2) The transmission is stable, with buffering, damping capacity and low noise;

(3) The transmission efficiency is high, up to 0.98, and the energy saving effect is obvious;

(4) Convenient maintenance, no lubrication, low maintenance cost;

(5) The speed ratio range is large, generally up to 10, linear speed up to 50 m / s, with a large power transmission range, up to several watts to hundreds of kilowatts;

(6) It can be used for long-distance transmission with a center distance of more than 10 m.

Pu synchronous belt is made of steel wire rope or glass fiber as the strong layer and polyurethane ring belt or open belt as the outer layer. The inner circumference of the belt is made into toothed shape to mesh with toothed pulley. When the synchronous belt drives, the transmission ratio is accurate, the force on the shaft is small, the structure is compact, the oil resistance, wear resistance and aging resistance are good. The general use temperature is -20 C - 80 C, v<50m/s, P<300kw and i<10. The synchronous transmission can also be used for low speed transmission.
