n.奥氏体变形
vt 奥氏形变.
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。
In this thesis, a new advanced technology, called ausform finishing, is first presented in our country for manufacturing hardened gears. 本文创新提出了用于硬齿面精加工的精密热滚挤技术。
At last, the design of the prototype machine for ausform finishing process is carried out, and compensating measures of machining error are put forward. 最后，对热滚挤加工设备样机进行了设计，并提出了加工误差的消减措施。
