Planetary Gearbox with High Efficiency Planetary Helical Gear Units
NGW series gearboxes consist of single-stage(NGW11-NGW121),two-stage(NGW42-NGW122) and stree-stage(NGW73-NGW123).
1.Model Number
NGW, NGW-L, NGW-S, NGW-QJ
2.Applications
NGW Planetary Gear Units is widely used in many areas such as metallurgy, mine, lifting, transportation, textile, cement, light industry, chemical, pharmaceutical, dye printing and so on. 
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
