Abstract
Bearing components, such as cages, rings, retainers, washers, spacers and the like, are formed from flat stock strips in preference to the employment of known methods of blanking same from stock having a dimension as great or greater than the larger dimension of the end product.
Claims3
A method of making a bearing cage comprising the steps of:
- forming a first outside strip of flat metallic stock with opposite side face portions turned inwardly in parallel planes normal to the plane of the main face portion,
- forming the main face portion of the first outside strip with a plurality of equi-spaced ball or roller openings therethrough,
- forming the first outside strip into a first annular ring with the confronting end edges fused together and with the main face portion defining a first cylindrical annulus of a certain outside diameter,
- forming a second inside strip of flat metallic stock with opposite side face portions turned outwardly in parallel planes normal to the plane of the main face portion,
- forming the main face portion of the second inside strip with a plurality of equi-spaced ball or roller openings therethrough,
- forming the second inside strip into a second annular ring with the confronting end edges fused together and with the main face portion defining a second cylindrical annulus of an inner diameter less than the certain outer diameter of the first annulus,
- joining the respective side face portions of the main face portion of the first and second annular rings to each other with the outside side faces of the inside ring being nestably received inside of the inside side faces of the outside ring in defining a pair of coaxial annuli equally spaced as to each other throughout their circumferences.
