High temperature synchronous belt transmission combines many advantages of belt transmission, chain transmission and gear transmission, and is a transmission belt with high transmission ratio accuracy. The transmission principle is that the convex teeth on the belt and the tooth groove on the pulley are forced to mesh and work. That is, when the driving pulley rotates, it can rely on the sequential meshing of the teeth and the pulley to transmit the motion and power to the driven pulley. Therefore, there is no slip phenomenon in the transmission, that is, the linear speed of the driving wheel and the driven wheel are the same, and the linear speed of the master and driven wheels can be synchronized. The angular speed of the pulley is kept stable without impact. Good vibration absorption performance, low noise; light weight of transmission device, little heat accumulation, no slipping due to forced engagement, so the transmission is more accurate, and high efficiency of more than 98% can be obtained, as shown in Figure 5; large speed range, generally up to 10, highest The speed can reach 50m / s; the power can range from several W to several hundred KW; the tension of the belt is small, the pressure on the shaft is light, the bending deformation of the shaft is reduced, and the service life of the bearing can be extended; It is suitable for multi-axis transmission and transmission with large center distance. The high-temperature timing belt has some advantages of belt transmission, chain transmission and gear transmission. Therefore, when the center distance between the two shafts is large, the speed ratio is required to be constant, the oil is not allowed to be contaminated around the machine, and the operation is stable and no noise. At the time, synchronous belt transmission is often the most ideal transmission method.
