  • spur gear shaft for construction machinery

    spur gear shaft for construction machinery

    This spur gear shaft used in construction machinery .  Gear shafts in transmission machinery are usually made of 45 steel in high-quality carbon steel, 40Cr, 20CrMnTi in alloy steel, etc. Generally, it meets the strength requirements of the material, and the wear resistance is good. This spur gear shaft was made by 20MnCr5 low carbon alloy steel ,carburizing into 58-62HRC.

  • DIN6 internal helical gear housing in high precision gears

    DIN6 internal helical gear housing in high precision gears

    DIN6 is the accuracy of the internal helical gear . Usually we have two ways to meet high accuracy .

    1) Hobbing + grinding for internal gear

    2) Power skiving for internal gear

    However for small internal helical gear ,hobbing is not easy to process ,so normally we would do power skiving to meet the high accuracy and also high efficiency .For big internal helical gear ,we will use hobbing plus grinding method . After power skiving or grinding ,middle carton steel like 42CrMo will do nitriding to increase the hardness and resistance

  • helical internal gear housing for planetary reducers

    helical internal gear housing for planetary reducers

    This helical Internal gear housings was used in planetary reducer . Module is 1 ,teeth :108

    Material :42CrMo plus QT ,

  • power skiving internal ring gear for planetary gearbox

    power skiving internal ring gear for planetary gearbox

    The helical internal ring gear was produced by power skiving craft ,For small module internal ring gear we often suggest to do power skiving instead of broaching plus grinding ,since power skiving is more stable and also has high Efficiency ,it takes 2-3 minutes for one gear ,accuracy could be ISO5-6 before heat treat and ISO6 after heat treatment .

    Module is 0.8 ,teeth :108

    Material :42CrMo plus QT ,

    Heat Treatment :Nitriding

    Accuracy: DIN6
