1. Compared with the ordinary cylindrical geared reducers of the same level, their weight is 1/2 lower and their volume is only 1/2-1/3 of the former. 2. Their transmission efficiency is very high. 1-stage achieves 97%, 2-stage 94%, 3-stage 91% 3. The range of transmission power is very wide, from 1kw to 1300kw 4. Produced with hard-tooth-faced, they can be used widely and in long period.[...]

1.1 Features: It adopts the combination of skew gear and worm, and vertical output so that the structure is compact and the speed ratio is large. 1.2 Installation and output types: base type, flange type, small flange type, torsion arm type installation, and output through hollow or solid shaft. 1.3 Input types: coupled-type motor, input through shaft and input through coupling flange. 1.4 Speed reducing ratio: 23.8-389, it is as high as 26688 for combination of EWS/EWR. 1.5[...]

Features: small off-center output and compact structure, maxi mum utilization of housing space, integral casting housing with a good rigidity to enhance the shaft strength and service life of bearing.[...]
