This invention is generally related to a bearing ring and more particularly to a method of forming the bearing ring.
Known solutions for forming bearing rings from sheet metal lack clearance for ends of rollers. Typically, post-formation tooling is required to create undercuts in the bearing rings to provide clearance for the ends of the rollers.
It would be desirable to provide a simple method for forming undercuts in a bearing ring without post-formation tooling.
A method for manufacturing a bearing ring is provided. The method includes punching out a blank from sheet metal. A radially extending groove is formed in the blank. The blank is stamped in a cup-shaped die which creates an axially extending side wall and a bottom wall, with a first undercut formed by the radially extending groove located at a juncture between the side wall and the bottom wall at a first axial end portion of the bearing ring. A second axial end portion of the side wall is thinned. The second axial end portion is then bent creating a flange with a second undercut located at a juncture between the flange and the side wall.
Preferred arrangements with one or more features of the invention are described below and in the claims.
The foregoing Summary as well as the following Detailed Description will be best understood when read in conjunction with the appended drawings. In the drawings:
Certain terminology is used in the following description for convenience only and is not limiting. The words “inner,” “outer,” “inwardly,” and “outwardly” refer to directions towards and away from the parts referenced in the drawings. A reference to a list of items that are cited as “at least one of a, b, or c” (where a, b, and c represent the items being listed) means any single one of the items a, b, c or combinations thereof. The terminology includes the words specifically noted above, derivates thereof, and words of similar import.
A method for manufacturing a bearing ring is provided. The bearing ring is preferably formed from low carbon steel. As shown in
Having thus described various embodiments of the present methods of manufacturing a bearing ring in detail, it is to be appreciated and will be apparent to those skilled in the art that many changes, only a few of which are exemplified in the detailed description above, could be made in the methods without altering the inventive concepts and principles embodied therein. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore to be embraced therein.
