追溯了齿轮制造技术的发展历程,比较了三代制造技术的特征,阐释了"无应力集中"抗疲劳制造的先进性。探讨了作为关键基础技术的3种齿轮表层硬化精密热处理技术——渗碳、氮化、感应淬火的工艺发展状况、先进工艺及力学性能等,从优化控制表面变质层的硬度梯度、残余应力场、组织结构及减小热处理畸变入手,创新发展齿轮的精密热处理,大幅度地提高齿轮的抗疲劳性能,从而解决齿轮结构重、寿命短、可靠性差的"三大问题"。预测齿轮抗疲劳精密热处理的发展趋势是"超硬化"、"深层化"、"复合化"、"真空离子化"等。
The development course of gear manufacturing technology is reviewed,the characteristics ofthree generation manufacturing technology are compared,the advancement of‘no stress concentration'anti-fatigue manufacturing is interpreted. The development situation,advanced technology and its mechanical property of three kinds of gear surface hardening precision heat treatment as key basic technology are discussed including carburization,nitriding and induction quenching. By optimizing and controlling the hardness gradient,re-sidual stress field,micro structure and distortion of surface metamorphic layer,the innovation and developmentof gear precision heat treatment,the gear anti--fatigue performance is greatly improved,and then solve the threemajor problems of gears such as heavyweight,short life and low reliability. The development trend of gear anti-fatigue precision heat treatment is predicted to be‘super hardening',deep case hardening',‘combined hard-ening',and‘vacuum ion heat treatment'.
