Synchronous Pulley is composed of a closed round rubber with teeth and attached pulley, while working, teeth and trough is in harmany, when moving, causing transmission of teeth, chain and belt.
　　 It has precise driving determining and no slip, costant speed and stable transmission, vibration-absorption, little noise. Range of can reach to 1:10 with allowable speed of 50M/S, transmission power could be from a few watt to hundreds or thousands watts. It is of high transmission efficiency, with average of 90%, with compact structure, and fit for multi-axle transmission, without lubricant and without contamination, so it can work normally under the condition of non-contamination and poorer environmental working places.
　　 The product is widely used in the mechanical transmission inthe line of textile, tobacco, communication cable, light Industry, chemicals, metallurgical Industry, instruments and appliances,food Industry, mining, petroleum and automobile.
