ASSEMBLING UNIT OF BALL SCREW AND ASSEMBLING METHOD OF BALL SCREW USING THEREOF

摘要

PROBLEM TO BE SOLVED: To provide the assembling unit of a ball screw which can fill a ball in a nut without clearance and fill the ball in a short time and the assembling method of the ball screw using thereof.;SOLUTION: Since a motor 31 is connected with a nut seat 27 by the linkage mechanism 38, the rotating member 33 rotates and the first coupling 34 turns around the rotating shaft of the motor 31 when the rotating shaft of the motor 31 continues rotation. The nut seat 27 is swingingly moved around the shaft center by repeatedly moving the connecting member 37 horizontally around the shaft center of the nut seat 27. Thereby, the non-filling space of the ball occurs repeatedly in the screw-thread race of the nut whenever it oscillates and moves, the ball enters into the non-filling space easily and it becomes possible to fill the ball in a short time.;COPYRIGHT: (C)2009,JPO&INPIT
