Description
Hot Sell OEM Forging large module herringbone gear wheel large Double Helical Gear
We can produce large forging,casting and welding gears according to customer’s drawings.According to the working conditions and clients’ request,we also can do gear grinding,surface hardening,cemented and quenching,Nitriding and quenching,etc.
Heat treatment forHot Sell OEM Forging large module herringbone gear wheel large Double Helical Gear–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 property and can prolong the gear’s service life.
Gear machining
Precision gear hobbing in 2-3 times to guarantee it’s gear accuracy and surface roughness.Only in this way,the spur pinion gear can work well with the large ring gear or gear shaft.
Inspection
When gear be finished.,we will provide our reports of raw material,hardness,size information to you.
