1. The instantaneous transmission ratio is constant. The instantaneous transmission ratio of non-circular gear transmission can be designed according to the changing rules of demand.
2. The transmission ratio is large and can be used to reduce or increase speed.
3. The speed (refers to the circular speed of the knuckle) and the transmission power are large in scale, which can be used for the transmission of high speed (v>40m/s), medium speed and low speed (v<25m/s); The power ranges from less than 1W to 105KW.
4. High transmission power. A pair of high-precision involute cylindrical gears with a power of more than 99%.
5. Compact structure, suitable for close transmission.
6. Manufacturing costs are high. Some new energy vehicle gears with special tooth shape or high precision require special or high-precision machine tools, cutters and gauges, so the manufacturing process is messy and the cost is high.
7. The transmission power can be from very small to hundreds of thousands of kilowatts; The speed can reach 300 m/s; The gear diameter of new energy vehicles can range from a few millimeters to more than 20 meters. However, the manufacturing of new energy vehicle gears requires special equipment, and meshing transmission will produce noise.
8. No overload maintenance function. The gear transmission of new energy vehicles is stable, the transmission ratio is accurate, the work is reliable, the power is high, the service life is long, and the applied power, speed and size are large. Now this transmission method is very popular and widely used.
