WIPO Patent Application WO/2022/209260
Kind Code:

Abstract:
This method for manufacturing a ball screw device comprises a nut unit preparation step, a screw shaft preparation step, and an assembly step. In the nut unit preparation step, a nut unit is prepared in which a circulating component, balls, and a provisional shaft for preventing dropping of the balls are assembled to a nut provided with an inner peripheral threaded surface. In the screw shaft preparation step, a screw shaft provided with an outer peripheral threaded surface is prepared. In the assembly step, after the nut unit preparation step and the screw shaft preparation step, the provisional shaft of an arbitrary nut unit is replaced with an arbitrary screw shaft to manufacture the ball screw device.
