摘　　要：在Litvin等的预设定传递误差曲线螺旋锥齿轮主动设计方法基础上,考虑初始计算点位置对安装误差敏感性的影响,对预设定传递误差曲线螺旋锥齿轮主动设计方法进行了改进。通过安装误差敏感系数的计算与比较,确定合理的初始计算点位置,由局部综合法求得满足预设定传递误差曲线且容差性较好的一组小轮加工调整参数。计算实例表明,合理选择初始计算点可使误差敏感系数数值平均下降26.68%。Based on traditional active design theory of spiral bevel gear in which parabolic function of transmission errors was predesigned, the influence of the position of mean contact point to mounting error sensitivity was considered and an improved active design method was proposed. Lower mounting error sensitivity was achieved by choosing the position of mean contact point properly. Pinion machine-tool setting parameters which satisfied predesigned parabolic function of transmission errors and better tolerance limit could be calculated according to local synthesis. Example indicates that the value of mounting error sensitivity factors declines at an average of 26.68 percent by choosing proper position of mean contact point.
