中文摘要：
为保证弧齿锥齿轮副在实际工况下具有良好的齿面印痕与啮合状态,研究安装错位的识别技术以及错位条件下的齿面再设计技术.分析可导致相同齿面印痕的多种安装错位组合之间的关系;提取齿面印痕的数值特征,以两接触轨迹曲线的偏差和最小为目标函数,采用优化方法识别当量安装错位;基于局部综合法,根据当量安装错位重新设计小轮的齿面.以一对弧齿锥齿轮副为例,比较实际安装错位与当量安装错位作用下的小轮再设计齿面的差曲面,验证了该设计方法的正确性和有效性.
英文摘要：
The identification of misalignment and redesign of pinion surface were proposed to get favorable contact pattern and operating performance in actual conditions for spiral bevel gears. The relationship among different groups of misalignment which would lead to the same contact pattern was studied. The digital features of contact pattern were extracted, and the equivalent misalignment was obtained by an optimal method according to the minimum sum of contact path deviation. Machine settings of pinion were redesigned by local synthesis with consideration of misalignment. A numerical example is presented to illustrate this method, of which the effectiveness is verified by comparing the deviation between pinion surfaces redesigned according to actual misalignment and equivalent misalignment.
