The company's main products are high-precision involute gears and gear shafts. We specialize in the manufacturing of spur gears, helical gears, herringbone gears, external splines, internal splines, cycloidal wheels, pin gear shells, new energy automobile gears and other gear products .

Products are widely used in the wind power industry: wind turbine planetary gears, sun gears, high-speed gears, ring gears, etc., rail locomotive industry, shipbuilding industry, petroleum industry, aviation gears, compressor gears, RV reducer cycloid wheels and pin gear shells, Coal mining machinery and reducer industry, lifting machinery and many other industries.

Our customers include CRRC, Yuanjing, Italian Cappi Gear, Double Ring Transmission, Guomao Reducer, NGC, Hitachi Compressor, etc.

The types of material are: forge piece, dieforge piece,castings,welded piece,steel rods and so on. The various heat treatment methods applied todifferent raw materials are : carburizing and quenching, sub-zero treatment ,gas nitriding,ionitriding,induction quenching, overallquenching,hardening and tempering and so on.

For heavy duty and high speed gears, materials containing Ni such as 17CrNiMo6.18CrNiM07-6.18Cr2Ni4WA are adopted. This type of materialhas high core toughness and surface hardenss with strong bending resistance and torque resistance after approperiate carburizing and quenching.High hardness surafce and high accuracy grinding makes the tooth surface become highly wear resistant.

We can process gear of precison grade as per diferent national standards: such as DlN 3-6 grade,AGMA10-13 grade,1s0 3-6 grade, jls 0-2 grade GB 3~6 grtade , etc.

We can also make modifcations to various tooth profles and helixes according to the diferent applications as wellas customer's requirements . Themain modifcation methods aplied to gear grinding machine with form wheel are: crowned shape ,crowned shape with slope,K shape, tooth widthasymmetric modifcation. Tooth surface roughness may reach Ra0,4. Appropriate modiication and relatively high tooth surface roughness mayeffectively control the meshing noise and prolong the service life.
