滚珠丝杠装置
摘要：
本发明提供一种滚珠丝杠装置。滚珠丝杠装置具备丝杠轴、螺母、由多个主滚珠构成的滚珠列、设置在滚珠列中的多个螺旋弹簧。通过丝杠轴的旋转在轴向力作用于螺母的状态下螺母从轴向一侧向轴向另一侧移动。多个螺旋弹簧在滚珠列的轴向一侧比轴向另一侧配置得密。
摘要（英）：

A ball screw device includes a screw shaft, a nut, a ball train including a plurality of main balls, and a plurality of coil springs disposed in the ball train. The nut moves from a first axial side to a second axial side while an axial force is applied to the nut by rotation of the screw shaft. The plurality of coil springs are more densely arranged on the first axial side than on the second axial side in the ball train.
