Abstract
A rolling-element bearing assembly includes an inner race and an outer race and a plurality of rolling elements between inner and outer races, the rolling elements being mounted in pockets between axial bridges of a cage having first and second axial side rings. One or both of the side rings has at least one corrugated surface, and the corrugations project axially and/or radially.
Claims17
A rolling-element bearing assembly comprising:
- a radially inner race surface;
- a radially outer race surface;
- a plurality of rolling elements disposed between the radially inner race surface and the radially outer race surface and received in a cage, the cage including a first side ring and a second side ring axially spaced from the first side ring by a plurality of bridges, adjacent bridges of the plurality of bridges forming pockets for receiving, spacing, and guiding the plurality of rolling elements;
- and
- at least one corrugated surface formed on at least one of the first side ring and the second side ring, the corrugated surface comprising a series of corrugation peaks and a series of corrugation valleys provided in an alternating arrangement, the series of corrugation peaks and the series of corrugation valleys being arranged such that each corrugation valley of the series of corrugation valleys is disposed axially adjacent to a region of a rolling-element center and each corrugation peak of the series of corrugation peaks is disposed axially adjacent to a bridge, wherein each corrugation peak of the series of corrugation peaks rises axially outwardly from a respective corrugation valley of the series of corrugation valleys,
- wherein the radially inner race surface is disposed on a first component and the radially outer race surface is disposed on a second component,
- wherein the first component and the second component are rotatably supported with respect to each other,
- wherein the rolling-element bearing assembly is bordered axially by at least one of a side wall of the first component and a side wall of the second component, wherein the at least one of the first component side wall and the second component side wall extends at least partially radially beyond the corresponding race surface.
A cage for a rolling-element bearing assembly, comprising a first side ring and a second side ring axially spaced from the first side ring by a plurality of bridges, adjacent bridges of the plurality of bridges forming pockets for receiving, spacing, and guiding a plurality of rolling elements;
- and
- at least one corrugated surface formed on at least one of the first side ring and the second side ring, the corrugated surface comprising a series of corrugation peaks and a series of corrugation valleys provided in an alternating arrangement, the series of corrugation peaks and the series of corrugation valleys being arranged such that each corrugation valley of the series of corrugation valleys is disposed axially adjacent to a region of a rolling-element center and each corrugation peak of the series of corrugation peaks is disposed axially adjacent to a bridge, wherein each corrugation peak of the series of corrugation peaks rises axially outwardly from a respective corrugation valley of the series of corrugation valleys.
A cage for a rolling-element bearing assembly, comprising a first side ring and a second side ring axially spaced from the first side ring by a plurality of bridges, the bridges defining pockets for receiving, spacing, and guiding a plurality of rolling elements;
- and
- at least one corrugated surface formed on at least one of the first side ring and the second side ring, the corrugated surface comprising a series of corrugation peaks and a series of corrugation valleys provided in an alternating arrangement,
- wherein the at least one corrugated surface is an axially outwardly facing surface of the cage,
- wherein at least one of the first side ring of the cage and the second side ring of the cage includes an axially outwardly facing corrugated surface,
- wherein the axially outwardly facing corrugated surface is located radially between a first smooth annular surface and a second smooth annular surface.
