1.Planetary Structure. The ratio of transmission is 3 to 10. It has the advantages of power split, small volume and light weight. Compared with parallel shaft gear box under the same loading condition, the volume of planetary gear box is reduced by 1/3 to 1/2 and the weight is reduced by 1/2.
2.The gear boxes of planetary series adopt floating high-speed shaft, which is able to reduce the bearing loss and increase the efficiency meanwhile. The efficiency is no less than 98.5%.
3.The power range is large, which could be from 1KW to 32000KW.
4.The rotate speed of high-speed shaft could reach up to 73000 revolutions per minute.
5.It could be designed in accordance with the order form and multiple connector types could be supplied. 
6.It could bring its own high-speed gear coupling and there is no need of high-speed bearing to support that simplifies the connector.
7.It is equipped with input and output coaxes that reduces the unit installation space. 
8.It adopts sliding bearings that has simple structure, long lifetime, convenient maintenance, small vibration and low noise.
