Abstract
A cage segment is for a rolling-element bearing cage, particularly for large rolling-element bearings. The cage segment includes a first side element and a second side element that are connected by a first bridge and a second bridge. At least one pocket is formed between the first and second bridges which is suitable for receiving at least one rolling element. The cage segment is manufactured from sheet metal.
Claims13
A cage segment for a rolling-element bearing cage for large rolling-element bearings, the cage segment comprising:
- first and second side elements;
- and
- first and second bridges each connecting the first and second side elements such that at least one pocket is formed between the first and second bridges, the pocket being configured to receive at least one rolling element;
- wherein the cage segment is manufactured from sheet metal.
A rolling-element bearing cage comprising:
- a plurality of cage segments, each cage segment including first and second side elements and first and second bridges each connecting the first and second side elements such that at least one pocket is formed between the first and second bridges, the pocket being configured to receive at least one rolling element and the cage segment being manufactured from sheet metal, and further including a first attachment element disposed on the first side element and/or a second attachment element disposed on the second side element;
- and
- wherein the plurality of cage segments are connectable at least temporarily by a coupling element engaged with the each of the first attachment elements or with each of the second coupling elements.
A rolling-element bearing comprising:
- at least one inner ring, at least one outer ring, a plurality of rolling elements disposed between the inner ring and the outer ring;
- and
- a rolling-element bearing cage holding the plurality of rolling elements and including a plurality of cage segments, each cage segment including first and second side elements and first and second bridges each connecting the first and second side elements such that at least one pocket is formed between the first and second bridges, the pocket being configured to receive at least one rolling element and the cage segment being manufactured from sheet metal, and further including a first attachment element disposed on the first side element and/or a second attachment element disposed on the second side element,
- wherein the plurality of cage segments are connectable at least temporarily by a coupling element engaged with the each of the first attachment elements or with each of the second coupling elements.
A method for manufacturing a cage segment from sheet metal, the method comprising the steps of:
- releasing an unfolded form of the cage segment from a piece of sheet metal, and
- bending and/or folding the unfolded form in order to form the cage segment.
