Synchronous belt drive principleWill tell, urgently!
The line speed of transmission can reach 50m/s, the transmission ratio can reach 10, and the efficiency can reach 98%. Transmission noise ratio belt drive, chain drive and gear drive is small, good wear resistance, no oil lubrication, longer life than the friction belt. The main disadvantage is that the requirements of manufacturing and installation are higher, and the requirement of center distance is strict. Therefore, the synchronous belt is widely used in the middle and small power transmission with accurate drive ratio.
But the synchronous belt drive requires higher central distance and dimensional stability. Synchronous belt drive has the advantages of belt drive, chain drive and gear drive. Synchronous belt drive, because the belt and pulley are meshing, transfer movement and power, so there is no relative slip between belt and pulley, which can ensure accurate transmission ratio. The belt is usually made of steel wire or glass fiber rope. It is made of neoprene or polyurethane. It is thin and light, so it can be used at higher speed.
Meshing belt drive is also commonly known as synchronous belt drive. It transmits motion through the equal distribution of transverse teeth on the inner surface of the belt and by the engagement of the corresponding teeth on the pulley. Compared with the friction belt drive, there is no relative sliding between the belt pulley and the drive belt in the synchronous belt drive, and the strict drive ratio can be ensured
