HNBR TIMINGBELT ,The synchronous belt drive is made up of a closed annular belt with equal spacing teeth and a corresponding pulley inside the inner surface. When working, the cogging of the toothed belt and the pulley is a kind of combined transmission, so it has the advantages of gear transmission, chain transmission and belt transmission. The transmission is accurate, stable, and the noise is small, and the constant speed ratio can be obtained, and the speed ratio range is large, the line speed is high, the transmission structure is compact, and the multi axle transmission is suitable. The synchronous belt produced by our company has excellent flexion resistance, low elongation and high strength. It also has excellent performance of oil resistance, heat resistance, aging resistance, ozone resistance, cracking and cracking.
