滚动丝杠螺母传动装置具有传动效率高（达0.95～0.98）和无间隙等优点,已得到广泛的应用。根据螺纹形状、钢球返回方法和施加过盈的方法,可分为表1的几种结构形式,通过表1能够了解各种结构的工艺特点,从而进行合理选用。 图1为过盈量可以自动调节的滚动丝杠螺母传动装置的结构图。 梯形螺纹传动装置工作表面的曲率悬殊很大,其负荷能力是很低的,因此,会引起很高的接触应力。对于弧形和半圆形螺纹来 Rolling nut drive with high transmission efficiency (up to 0.95 ~ 0.98) and no gaps, etc., has been widely used. According to the thread shape, ball return method and the method of applying interference can be divided into several structures in Table 1, through Table 1 can understand the characteristics of various structures of the process, so as to be a reasonable choice. Figure 1 is the amount of interference can be automatically adjusted rolling screw nut actuator block diagram. Trapezoidal thread transmission work surface great disparity in the curvature, its load capacity is very low, therefore, can cause high contact stress. For curved and semi-circular threads
