METHODS FOR MANUFACTURING FLANGED CYLINDRICAL MEMBER, FLANGED ROLLING BEARING, ROTARY MACHINE, AND VEHICLE

摘要

PROBLEM TO BE SOLVED: To realize a method for sufficiently securing thickness in a radial direction of a portion forming a flange part.;SOLUTION: A final intermediate material 22 is obtained that includes a cylindrical part 29, and a bulged part 30 protruding outward in a radial direction from an outer peripheral surface of an end part in an axial direction of the cylindrical part 29, by subjecting a ring-shaped intermediate material 21 to reverse processing in which an inside portion in a radial direction is expanded in diameter, and an outside portion in the radial direction is reduced in diameter.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2020,JPO&INPIT
