Abstract
PURPOSE: To prevent abnormal wearing by guiding the cylindrical holder by the ball screw shaft and the nut without applying the force of the ball on the holder during the ball screw device is in operation.
CONSTITUTION: The holder 6 is combined with the ball screw shaft 3 and the nut 1 by the radius direction projecting part 9, the frange 10, and the snap ring 11. Then, the holder 6 is shifted in the axial direction for L without turning. At this time, the initial intersecting point Co of the parallel surface 7 formed on the ball holding port 8 of the holder 6 and the center line of the helical concaved groove is shifted to C1 point for L. The new intersecting point of the parallel surface 7 and the helical concaved groove 4 is moved to C2 point. By this constitution, by eliminating the effect of the ball, abnormal wearing can be prevented.
