Manufacturer supplier exporter of herringbone gear.

We can produce large forging, casting, and welding gears according to the customer’s drawings. According to the working conditions and clients’ requests, we also can do gear grinding, surface hardening, cementing and quenching, Nitriding and quenching, etc.

Heat treatment for High Quality Forging large diameter Herringbone Gear wheel–quenching and tempering

If the gear module is large (above M25), we do the first-time gear hobbing before heat treatment. According to this way, the gear teeth’ hardness depth after QT will be deeper, thus can improve the gear teeth’ mechanical properties and can prolong the gear’s service life.
Gear machining
Precision gear hobbing 2-3 times to guarantee its gear accuracy and surface roughness. Only in this way the spur pinion gear can work well with the large ring gear or gear shaft.
When gear be finished.,we will provide our reports of raw material, hardness,  and size information.
