滚珠丝杠副产生弹性接触变形时实际接触角的计算

Calculation of actual contact angle during elastic contact deformation between recirculating ball screw and nuts

本文提出了在预载过盈条件下，单螺母变位导程预加负荷滚珠丝杠副钢球和滚道弹性接触变形模型及实际接触角的计算方法，还推荐了合理的原始设计接触角。

The article proposes the model of elastic deformation between ball and race of recirculating ball screw and nuts under preload with variable lead single mut and the calculation method for actual contact angle. The values of reasonable original design contact angles are also recommended.
