1, constant instantaneous gear ratio. The instantaneous gear ratio of the non-circular gear drive can be designed according to the changing law.
2, a large range of transmission ratio, can be used for deceleration or speed increase.
3, speed (circumference circle speed) and transmission power range, can be used for high speed (v> 40m / s), medium and low speed (v <25m / s) drive; power from less than 1W to 10KW.
4, high transmission efficiency. A pair of high-precision involute cylindrical gears, the efficiency of up to 99%.
5, compact structure, suitable for close-distance transmission.
6, higher manufacturing costs. Some gears with special tooth shapes or high precision require specialized or high-precision machine tools, knives, and gauges, making the manufacturing process complex and costly.
7, The gears with low precision, noise during transmission, great vibration and shock, pollute the environment.
8, no overload protection
