Overview

This product is an external toothing involute helical gear cylindrical gear reducer produced as per the national standaJB/T8853-2001.With optimal design,it's equivalent to the international level in the 1980s.

This product is widely applied in such industries as metallurgy,mine,hoisting,transportation,cement,building,chemengineering,textiles,printing and dyeing,and pharmacy.

The reducer's application scope is as follows

1.High-speed shaft's rotation speed:not higher than 1,500r/min.

2.Gear transmission's peripheral speed: not higher than 20m/s.

3. Working ambient temperature: -40~45℃; if lower than 0℃,lubricating oil shall be preheated to above O℃ before startireducer is available for running in either forward or reverse direction.

Characterstics

1.Reduction ratio range: nominal reduction ratio 1.25~5.6 for single-stage,6.3~ 20 for double-stage and 22.4~100 fo

2.High efficiency of mechanicaltransmission: higher than 96.5% for single-stage, higher than 93% for double-stage a90% for three-stage.

3.Stable and low-noise operation.

4.It'scompact and light with long service life and high bearing capacity.

5.It's easy for strip inspection and installation.

Reducer type, specification and designation

1.Types available:ZDY single-stage cylindrical gear reducer,ZLY two-stage cylindrical gear reducer and ZSY three-cylindrical gear reducer.

2.Specifications available:Single-stage:80、100、125、160、200、250、280、315、355、400、450、500、560;Two-stage:112、125、140、160、180、200、224、250、280、315、355、400、450、500、560、630、710;Three-stage:160、180、200、224、250、280、315、355、400、450、500、560、630、710
