摘　　要：回转误差对于定日镜精密蜗杆传动副精度影响极大,研究分析回转误差精度可以有效地评价其传动特性是否满足要求。利用几何分析法得出了蜗杆传动副的常值侧隙和变值侧隙的表达式,为了预测其侧隙的特性值,利用统计分析法对蜗杆传动副回差进行综合计算,得到了圆周侧隙的计算表达式。通过定日镜中精密蜗杆传动副的实例计算,验证了该方法计算所得回转误差精度与实际实验所测范围基本一致。Backlash has a great effect on the precision of the worm gearing transmission in heliostat,through the analysis of the backlash; the transmission characteristic of the worm gearing can be evaluated. First,the constant backlash and the variation backlash were gotten by means of the geometry method. Then,the equation of the circle backlash was derived by using statistical analysis method in order to get a precise solution. Through calculating heliostat of the precise worm gearing,it was proved that the present method was basically identical with answer comparing with the practical.
