Abstract
Official abstract text for this publication.
An axial section of a continuous portion where an outer peripheral surface of a spindle portion of a main spindle in which a punch is installed is continuous with an outer peripheral surface of a punch holder is formed of a first circular arc joined to the outer peripheral surface of the spindle portion and a second circular arc joined to the outer peripheral surface of the punch holder. The first circular arc and the second circular arc are in contact with each other. The second circular arc is smaller than the first circular arc in curvature radius.
First claim
Opening claim text (preview).
What is claimed is: 1. A hub unit manufacturing apparatus that, after an inner ring member is installed in a hub shaft of a hub unit, causes a punch to contact with a shaft end portion of the hub shaft to push and expand the shaft end portion while plastically deforming the shaft end portion so that the inner ring member is constrained by the hub shaft, the hub unit manufacturing apparatus comprising: a main spindle in which the punch is installed and which has: a cylindrical spindle portion; and a punch holder formed integrally with the spindle portion and having a larger diameter than the spindle portion, wherein an axial section of a continuous portion where an outer peripheral surface of the spindle portion is joined to an outer peripheral surface of the punch holder is formed of a first circular arc joined to the outer peripheral surface of the spindle portion and a second circular arc joined to the outer peripheral surface of the punch holder, the first circular arc and the second circular arc are in contact with each other, and the second circular arc is smaller than the first circular arc in curvature radius. 2. The hub unit manufacturing apparatus according to claim 1 , wherein the curvature radius of the first circular arc is 50%-200% of a diameter of the spindle portion. 3. The hub unit manufacturing apparatus according to claim 1 , wherein the curvature radius of the second circular arc is 5%-40% of the curvature radius of the first circular arc.
