摘　　要：为计算弧齿锥齿轮副在工况下的安装错位,研究了可导致相同齿面印痕的不同安装错位组合之间的关系.分析表明:它们之间存在等价关系;对于安装错位的识别,只要计算一组等效值即可,无需确定精确解.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,通过优化方法计算当量安装错位.最后以一对弧齿锥齿轮副为例验证识别算法的精度以及当量安装错位的有效性.In order to calculate the misalignment of spiral bevel gears in the working conditions, me relationship among different groups of misalignment which lead to the same contact pattern is analyzed. It is found that these groups of misalignment are equivalent, and the misalignment identification can be solved by getting only one equi- valent solution without exact calculation. Then, the digital features of contact pattern are extracted, and the equiva- lent misalignment is obtained using an optimal method by means of minimizing the sum of two contact path devia- tions as the objective function. Finally, the precision of the identification algorithm and the effectiveness of the equivalent misalignment are verified by taking a couple of spiral bevel gears as an example.
