Synchronous pulley characteristics　

(1) The transmission is accurate, there is no slippage when working, and it has a constant transmission ratio;　

(2) Smooth transmission, with buffering and vibration reduction capabilities, and low noise;　

(3) The transmission efficiency is high, up to 0.98, and the energy saving effect is obvious;　

(4) Convenient maintenance, no need for lubrication, and low maintenance cost;

(5) The speed ratio range is large, generally up to 10, and the linear speed can reach 50m/s, with a large power transmission range, up to several watts to several hundred kilowatts;　

（6）可用于长距离传动，中心距可达10m以上。 (7) 无污染,可在不允许有污染和工作环境较为恶劣的场所下正常工作 。
