Synchronous belt overview, characteristics and application


Overview of 1. synchronous belt: Synchronous belt transmission is composed of a circular belt with equal spacing teeth on the inner circumferential surface and a wheel with corresponding coincidence. It combines the advantages of belt drive, chain drive and gear drive. When rotating, power is transmitted through the engagement of the belt teeth with the tooth grooves of the wheel. The transmission synchronous belt drive has an accurate transmission ratio, no slip, a constant speed ratio, stable transmission, vibration absorption, low noise, and a large transmission ratio range, generally up to 1:10. Allows line speed up to 50 M/S, transfer power from a few watts to hundreds of kilowatts. High transmission efficiency, generally up to 98%, compact structure, suitable for multi-axis transmission, no lubrication, no pollution, so it can work normally in places where pollution is not allowed and the working environment is relatively harsh.

Features of 2. synchronous belt: 1. Accurate transmission, no sliding during operation, and constant transmission ratio; 2. Stable transmission, buffering and vibration reduction capabilities, and low noise; 3. High transmission efficiency, up to 0.98, and obvious energy saving effect; 4. The speed ratio range is large, generally up to 10, and the linear speed can reach 50 m/s. It has a large power transmission range, up to several watts to several hundred kilowatts; 5. It can be used for long-distance transmission, and the center distance can reach more than 10m; 6. Compared with V-belt transmission, the pre-tightening force is small, and the load on the shaft and bearing is small.

Application of 3. synchronous belt: synchronous belt is widely used in light industry, textile and CNC machine tools. Tobacco, communication cables, chemical industry, metallurgy, precision instruments, industrial robots, food, mining, automobiles, petroleum and other industries of various types of mechanical transmission.
