Title:
ASSEMBLY METHOD OF CONICAL BEARING
Document Type and Number:
Japanese Patent JP2022185519
Kind Code:
A
Abstract:
To provide an assembly method of a conical bearing which can inhibit deformations, such as oval deformation and twisting deformation, which affect rotation performance of the conical bearing and eliminate a need of pursuing strict dimensional tolerance to enable reduction of assembly costs.SOLUTION: A retainer 14 and an inner ring 12 are arranged relative to each other so that a radial axis of the retainer matches with a radial axis of the inner ring and multiple conical rollers 13 contact with a small flange part 15 of the inner ring in a state that the multiple conical rollers are retained by the retainer. At least one of the retainer and the inner ring is pressed along an axial direction parallel to the axis to move the retainer to the side of a large flange part 16 of the inner ring relative to the inner ring and cause the retainer to be deformed to the radial outer side through elastic deformation and plastic deformation. When the conical roller has passed through the small flange part of the inner ring, the retainer deformed to the radial outer side is deformed to the radial inner side to a position, at which the roller is prevented from getting over the small flange part and being removed, by spring back.SELECTED DRAWING: Figure 2
