1. Accurate transmission, no slippage during operation, and constant transmission ratio;
2. Smooth transmission, with buffering and vibration reduction capabilities, and low noise;
3. High transmission efficiency, up to 0.98, with obvious energy-saving effect;
4. Convenient maintenance , no lubrication, low maintenance cost;
5. The speed ratio range is large, generally up to 10, the line speed can reach 50m/s, and it has a large power transmission range, which can reach several watts to hundreds of kilowatts;
6. It can be used for Long-distance transmission, the center distance can reach more than 10m; 7. No pollution, can work normally in places where pollution is not allowed and the working environment is relatively harsh.
