Title:
PRESS-FIT METHOD OF SHAFT AND DEVICE THEREOF
Document Type and Number:
Japanese Patent JP3246135
Kind Code:
B2
Abstract:
PURPOSE: To easily press-fit two parts of a shaft into a part to be fitted so as to assemble them without causing bending or deformation of the shaft by applying compressive force on one end of the shaft and tensile force on the other end in the axial direction.
CONSTITUTION: When pressing force is applied on the upper end of a torsion bar 10 by a pressing part 21, the pressing force is simultaneously applied on the upper end parts of pressing rods 36, transmitted to a movable member 34 through the pressing rods 36, and applied on the lower end engaging part 10c of the torsion bar 10 locked with the movable member 34 as downward tensile force. Consequently, compressive force acts on the press-fitting part between a cylindrical part 11 and a serration part 10a, tensile force acts on the press-fitting part between a collar 12 and a serration part 10b, and hence unfavorable stress is not generated on the center small diameter part of the torsion bar 10. Hereby, the cylindrical part 11 and the collar 12 can be assembled with the torsion bar 10 without causing bending or deformation on its center small diameter part.
