3.Product Characteristics
(1) Small volume, light weight, well-knitted structure, big transmission power and high load capacity. Compared with the ordinary cylindrical gear reducers of the same level, its weight is lower 1/2 and volume is only 1/2-1/3 of the former.
(2) High transmission efficiency. 1-stage is up to 97%, 2-stage 94%, 3-stage 91%.
(3) The range of transmission power is very wide, from 1kw to 1300kw.
(4) NGW Planetary Gear Units is designed with hard-tooth-faced, and can be used widely and in long period.
(5) Big transmission ratio
