    Our company, Shenyang Hanwei Machinery Manufacturing Co.

    , Ltd, has plentiful experience and advanced technology in manufacturing of large ring gears according to the drawings.

    The large ring gear is one of the common mechanical parts, which can transmit and change the direction of the force.

    It belongs to the thin- walled ring forgings.

    By controlling the process of the forging details, the phenomena of wall unevenness, fold, and oval can be improved.

    It can be applied in the concrete mixer, ball grinding mill, dryer, sand- blasting machine, rotary kiln, excavator, wind power generation, etc

    Material: 42CrMo

    Initial forging temperature: 1220℃

    Final forging temperature: 750℃

    Brand: HANWEI

    Tooth Shape: Spur, Helical, Herringbone, etc

    Material: cast iron

    Tooth number: 11- 300

    Tooth Height: 2.25- 90mm

    Module: 1- 40mm

    Diameter: 100- 8000mm

    Tooth face hardness: hard tooth

    Ring Gear Processing:

    Blank forging → blank detection → Quenching and tempering treatment → lathe processing → gear hobbing → drilling → quenching treatment → flaw detection → high- temperature tempering → detection → packing

    The Quenching Heat Treatment of the Ring Gear

    The working environment of the ring gear is very poor and it needs to bear the huge force of friction.

    We usually enhance its hardness, property of abrasive resistance, and working life by the method of quenching with best quench equipments.
