GreatLoad Gear Reducer: 1. Optimizing design is made on the gears for hard-tooth-faced speed reducers in the national standard, and the actual bearing capability of some speed reducers is improved. 2. The box-type design has broken through the thinking model in which the hard-tooth-faced speed reducers are led by curves in the national standard, and has introduced a shape of polygon led by straight lines. 3. The polygon boxes can be mounted in any way and are adaptive widely 4. Small volume, light weight, low noise, high efficiency and long service life. Introduction Of High Load Speed Reducer (Polygon Mounted): Parallel-Shaft Series: Include the following type: 1-step speed reducers, with 18 stand no.s, 14 nominal gear ratios in range of 1.25 6.3; 2-step speed reducers, with 17 stand no.s, 11 nominal gear ratios in range of 6.3 20; 3-step speed reducers, with 14 stand no.s, 14 nominal gear ratios in range of 22.4 100; 4-step speed reducer, with 11 stand no.s, 14 nominal gear ratios in range of 112 500. The 2-4-step speed reducers have three outputting ways, i.e. solid-shaft, straight-key hollow shaft and shrinkage-disk hollow shaft; three mounting wats as developed base mounted, bottom surface installation, top surface installation, install lon the right, intstall on the lefe, the installation in the front surface, the installation on the behind surface; each surface have four kinds of installed postion from 1-4, can combine into more then thirty thousand types of polygon parallel-shaft hard-tooth-faced speed reducers. Applicable conditions for High Load Speed Reducers: 1. The peripheral speed of gear transmission of the speed reducer is no more than 20m/s; and the speed of high-speed shaft is no more than 1500 r/min. 2. The operation ambient temperature of reducer is -40oC +45oC (When it is lower than 0oC, you should heat the lube up to be more than 0 oC before starting). 3. The reducers can run both CW and CCW direction in principle. Technique parameter: 1. Power: 2.4 KW 6730 KW 2. Ratio:1.25 500 .
