Little knowledge of synchronous belt transmission

Mesh type belt drive, also known as general synchronous belt transmission. It through the inner surface equidistant distribution on the transverse tooth and belt pulley on the corresponding tooth meshing to transmit motion.

Compared with type friction drive belt, synchronous belt drive pulley and the belt there is no relative sliding between, to ensure strict ratio. But for synchronous belt transmission center distance and higher dimensional stability requirements.

Synchronous belt transmission possesses the advantages of belt transmission, chain and gear transmission. Due to the band and pulley synchronous belt transmission is passed by meshing movement and power, so there was no relative sliding between the belt and belt wheel, can guarantee the accurate transmission ratio. Synchronous belt is usually for wire rope or glass fiber rope tensile body, neoprene rubber or polyurethane as matrix, the thin and light, it can be used in high speed. Transmission with the linear velocity of up to 50 m/s, transmission ratio can reach 10, efficiency can reach 98%. Transmission noise is smaller than belt transmission, chain and gear transmission, good abrasion resistance, without oil lubrication, service life is longer than friction tape. Its main drawback is that manufacturing and installation accuracy is higher, more strict center distance. So the synchronous belt is widely used in requirements ratio of medium and small power transmission accurately.
