BALL SCREW, BALL SCREW ASSEMBLING DEVICE, AND METHOD OF ASSEMBLING BALL SCREW USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a ball screw assembling device enhancing the durability of a ball screw by filling a nut with a sufficient quantity of balls, and also to provide a method of assembling the ball screw using the assembling device.;SOLUTION: The offset amount L between the center axis of a ball pusher 45 and the inscribed circle of the balls 4 put in the screw groove 3a of the nut 3 is, where the diameter of the balls is Dw, the requirement of Dw/2 L Dw is desirable. More desirably, the offset amount L is set as close to Dw/2 as possible. When the offset amount L is larger than Dw, the balls may remain between the end of the ball pusher 45 and the track of the screw groove 3a.;COPYRIGHT: (C)2009,JPO&INPIT
