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.
Claims8
A cage segment for a rolling-element bearing cage for rolling-element bearings, the cage segment comprising:
- a first side element and a second side element;
- and
- a first bridge and a second bridge 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 and includes at least one slip surface and at least one support surface that is configured to support the at least one slip surface, the at least one slip surface including at least one of an inner slip surface formed on one side of the first or second bridge that faces the pocket and an outer slip surface formed on the other side of the first or second bridge that faces away from the pocket.
1 more element
A rolling-element bearing cage comprising:
- a plurality of cage segments, each cage segment including a first side element and a second side element and a first bridge and a second bridge 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 each cage segment includes at least one slip surface and at least one support surface that is configured to support the at least one slip surface, the at least one slip surface including at least one of an inner slip surface formed on one side of the first or second bridge that faces the pocket and an outer slip surface formed on the other side of the first or second bridge that faces away from the pocket;
- 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 attachment elements.
1 more element
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 a first side element and a second side element and a first bridge and a second bridge 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 each cage segment includes at least one slip surface and at least one support surface that is configured to support the at least one slip surface, the at least one slip surface including at least one of an inner slip surface formed on one side of the first or second bridge that faces the pocket and an outer slip surface formed on the other side of the first or second bridge that faces away from the pocket;
- 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 attachment elements.
