1.Feature and Applicable Scope:
The Polygon Hard-Tooth-Faced Speed Reducer from SR Co. are divided into two series i.e. Parallel-shaft cylindrical helical-gear speed reducers and orthogonal-shaft spiral bevel gear cylinder helical-gear reducers, can be widely used in shipbuilding, metallurgy, mine, transportation, energy source, cement, building, chemical, textile, light industry, etc.

2.Main features of polygon hard-tooth-faced speed 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

3. Technical Parameter:
Foot, hollow shaft, solid shaft and shrinkage disk connections
Can handle with backstop in order to rotate in single direction
Coupled with high power engines, achieve high capacity
