Product Description

High Torque Low Backlash Ratio 12:1 Planetary Gear Reducer

Nickel chromium molybdenum alloy steel gear is manufactured with carburizing heat treatment for high abrasion resistance and impact toughness and by honing process to increase gear precision and low noise operation.Internal gear bore uses needle roller to obtain higher abrasion resistance and strength.

Product Description

Description:
(1).The output shaft is made of large size,large span double bearing design,output shaft and planetary arm bracket as a whole.The input shaft is placed directly on the planet arm bracket to ensure that the reducer has high operating accuracy and maximum torsional rigidity.
(2).Shell and the inner ring gear used integrated design,quenching and tempering after the processing of the teeth so that it can achieve high torque,high precision,high wear resistance.Moreover surface nickel-plated anti-rust treatment,so that its corrosion resistance greatly enhanced.
(3).The planetary gear transmission employs full needle roller without retainer to increase the contact surface,which greatly upgrades structural rigidity and service life.
(4).The gear is made of Japanese imported material.After the metal cutting process,the vacuum carburizing heat treatment to 58-62HRC. And then by the hobbing,Get the best tooth shape,tooth direction,to ensure that the gear of high precision and good impact toughness.
(5).Input shaft and sun gear integrated structure,in order to improve the operation accuracy of the reducer.

1.With bevel gear reversing mechanism,right angle steering output is realized;
2.Square flange output,standard size;
3.The input specification are complete and there are many choices;
4.Spur transmission ,single cantilever structurer,design simple,high cost performance;
5.Keyway can be opened in the force shaft;
6.stable operation,low noise;
7.Size range:60-120mm
8.Ratio range:3-100;
9.Backlash:8-16arcmin;
10.Support custom according to drawings or samples
