摘要： A method that includes: providing a blank; heating the blank; forging the heated blank to form a forged gear having a plurality of spiral bevel gear teeth; machining the forged gear to a predetermined thickness while locating off of the plurality of gear teeth to form a green machined forged gear; rotationally and axially engaging a die to the gear teeth of the green machined forged gear to induce plastic flow in the gear teeth to form an intermediate gear in which the plurality of gear teeth conform to a predetermined tooth form; heat-treating the intermediate gear to form a hardened intermediate gear; and lapping the plurality of gear teeth of the hardened intermediate gear with a spiral bevel pinion gear; wherein the plurality of gear teeth are not machined in a chip-producing machining operation before the plurality of gear teeth are lapped.
