Abstract

917,856. Making bearings; forging; tube expanders. SCHAEFFLER, W., and SCHAEFFLER, G., [trading as INDUSTRIEWERK SCHAEFFLER OHG.]. June 18, 1959 [July 14, 1958], No. 21033/59. Classes 83 (2) and 83 (4). A needle roller bearing shell having openings for the bearing needles separated by webs extending between end rings or flanges and each opening having over its middle portion a width less than and at its ends a width greater than, the diameter of the needles is made from a tubular element of substantially the same external diameter as the middle portion of the shell and of wall thickness of about half the diameter of the needles by first forming the needle openings, bevelling the radially outer edges of the middle portion of the webs by external die members and then expanding the end rings or flanges and the end portions of the webs until the spacing between the end portions of the webs is greater than the needle diameter. A tubular blank 1 having openings separated by webs 8 is expanded at the ends by a shoulder 3 on a mandrel 20 and a shoulder 4 on sleeve 5 which is slidable over the mandrel as shown in Fig. 2. The middle portion of the blank is held by dies 6 of sector-like cross-section having on their radially inner surfaces projections 9 with bevelled surfaces for engaging the shaping the middle portion of each of the surfaces 7 of the webs 8.
