Document Type and Number:
Japanese Patent JP4497489
Kind Code:
B2
Abstract:
A process for producing a sheet metal cage for roller bearings involves using a press roll to form a disk-shaped circular sheet metal blank into a tubular element having radially inwardly projecting and axially extending ribs, and stamping window-shaped pockets into the tubular element between adjoining ribs to produce a cage of a rolling bearing for receiving rolls in the window-shaped cutouts. The sheet metal cage produced by the method possesses a conically rolled outer surface and side rings arranged at opposite ends. The cage includes ridges extending between the side rings and window-shaped pockets between adjacent pairs of ridges for receiving tapered rolls. The cage also includes ribs extending inwardly from each of the ridges, with the ribs possessing tapering side surfaces.
