During ausform finishing process of hardened gears, there is plastic displacement of metal on the tooth surface and the distortion of tooth profile.
在齿轮热滚挤加工中,轮齿上的金属在强制挤压力的作用下沿齿面产生塑性流动,使齿形发生变化。
Therefore, the conventional heat treatment process after forging can be replaced by the new ausform hardening process, to save energy and improve production efficiency.
