Verfahren zur Herstellung eine Hohlwelle mit einer Flansche an einem deren Enden

摘要

A method of securing a plate-like flange member at the front end of a hollow shaft member through a plastic working treatment by virtue of caulking combination, so as to manufacture a hollow shaft having a flange at one end thereof. In detail, the method comprises performing a shear spinning treatment on the outer periphery surface of the hollow shaft member (B) so as to reduce the size of the hollow shaft member (B) in its radial direction whereby engaging the front portion of the hollow shaft member (B) with a constricted portion (13a) of an axial projection (13) of the plate-like flange member (A).
