本文对内循环滚珠丝杠副反向器提出了新型回珠槽曲线（五次抛物线型）的设计方法。这种方法计算简单，并具有与正弦曲线相近的动态特性，即曲线具有“二阶连续性”，同时还可改变反向角来调节反向滚珠数量，保证参加工作的滚珠数量，提高接触刚性和承载能力。
In this paper, a new design method of bead return curve (quintic parabola) is proposed for inner circulating ball screw reverse inverter. This method is computationally simple and has a dynamic characteristic close to that of a sinusoid, ie, the curve has “second order continuity” and the reverse angle can be changed to adjust the number of reverse balls, to ensure the number of balls participating in the work and to improve the contact rigidity And carrying capacity.
