On the basis of the gear pair integrated error proposed by the authors in the past, a new computing and evaluating method of gear meshing impact was introduced to effectively overcome the existing problems of present research on gear meshing impact. The emerging process of meshing impact of the gear with manufacturing errors was explained, and three parts of teeth transition characteristic were researched. Six fundamental types of teeth transition process and their criteria were proposed. The relationship between the teeth transition types and gear meshing impact and the variation rules of teeth transition under load were introduced. Based on the above results, the gear meshing impact evaluation system (GMIES) was developed. The theoretical and simulational studies showed that the new method would be a new way to research, evaluate and control gear meshing impact.基于我国首创的齿轮整体误差测量技术,以笔者提出的齿轮副整体误差为手段,从微观上解释了齿轮啮合冲击产生的具体过程,归纳了轮齿交替特性,提出了一种以轮齿交替特性为评价准则的齿轮啮合冲击的评价方法:总结了6种基本的交替形式,给出了各自的判别准则,统一了齿面交替和顶刃交替的判别方法,讨论了各交替形式与啮合冲击的关系;最后,以上述理论为基础,开发了齿轮啮合冲击测评系统并给出了分析实例.研究结果表明。齿轮副整体误差是研究齿轮啮合冲击问题的一种有效工具,以轮齿交替特性为基础的统计学评价方法为批量齿轮啮合冲击的测评和预报提供了一种新的方法和途径.
