Abstract
A cage segment defines a single pocket of a multipart rolling-element bearing cage and includes first and second circumferentially spaced side walls connected by first and second end walls. The first and second side walls and the first and second end walls are formed by at least one sheet metal segment connected at at least one joint.
Claims20
A single-pocket cage segment of a multipart rolling-element bearing cage, the cage segment comprising:
- a first side wall and a second side wall connected by a first end wall and a second end wall,
- wherein the first and second side walls and the first and second end walls are formed by at least one sheet metal segment having at least two ends connected at at least one joint, and
- wherein the first side wall includes at least one functional element formed by pressing a first side of the first side wall to form a projection on an opposite side of the first side wall and/or the first end wall includes at least one functional element formed by pressing a first side of the first end wall to form a projection on an opposite side of the first end wall.
A single-pocket cage segment of a multipart rolling-element bearing cage, the cage segment comprising:
- first and second side walls connected by first and second end walls,
- wherein the first and second side walls and the first and second end walls are formed by at least one sheet metal segment having at least two ends connected at at least one joint,
- wherein the at least one sheet metal segment includes an embossment, a deep-drawn structure, or a flap bent out of a plane of the at least one sheet metal segment, and
- wherein the at least one sheet metal segment is a single sheet metal segment having a first end and a second end and the at least one joint is located between the first end and the second end.
A method comprising:
- providing a plurality of single-pocket cage segments of a multipart rolling-element bearing cage, each of the cage segments comprising first and second side walls connected by first and second end walls, wherein the first and second side walls and the first and second end walls are formed by at least one sheet metal segment having at least two ends connected at at least one joint,
- installing one of a first set of rolling elements into each of the plurality of cage segments, and
- arranging the plurality of cage segments and inserted rolling elements on a bearing ring with one of a second set of rolling elements between each adjacent pair of the plurality of cage segments.
