Abstract
A rolling-element bearing includes first and second rings having axial and radial raceways and a row of first radial rolling elements between the axial raceways. At least one row of axial rolling elements is located between a first radial raceway of the first ring and a first radial raceway of the second ring and radially located between an axial guiding face of the first ring and an axial guiding face of the second ring. The axial rolling elements are mounted in the pockets of a cage having a plurality of cage segments, and at least one second radial rolling element is circumferentially interposed between two adjacent cage segments of the plurality of cage segments and radially interposed between the axial guiding faces.
Claims20
A rolling-element bearing comprising:
- a first ring having a first axial raceway,
- a second ring having a second axial raceway,
- at least one row of first radial rolling elements radially interposed between the first and second axial raceways,
- at least one row of axial rolling elements axially interposed between a radial raceway of the first ring and a radial raceway of the second ring and radially located between an axial guiding face of the first ring and an axial guiding face of the second ring, and
- a cage for guiding said row of axial rolling elements, said cage comprising a plurality of successive circumferential cage segments, each of said cage segments including at least two pockets each containing at least one of the axial rolling elements, and
- at least one second radial rolling element circumferentially interposed between two adjacent cage segments of the plurality of cage segments, said at least one second radial rolling element being radially interposed between the first and second axial guiding faces,
- wherein each cage segment of the segmented cage comprises a first end and a second end circumferentially spaced from the first end,
- wherein the first end defines a first abutment surface and the second end defines a second abutment surface,
- wherein each of the at least one second radial rolling element abuts in the circumferential direction against the first abutment surface of a first one of the plurality of cage segments and the second abutment surface of an adjacent cage segment, and
- wherein each of the at least one second radial rolling element comprises an axial end face and a side wall in contact with the axial guiding face of the first ring, and
- wherein a diameter of each of the at least one second radial rolling element at the side wall is greater than a diameter of the axial end face.

- a first row of axial rolling elements located between the first radial raceway of the first ring and the third radial raceway of the second ring and radially located between a first axial guiding face of the first ring and a first axial guiding face of the second ring,
- a cage for guiding the first row of axial rolling elements, said cage comprising a plurality of successive circumferential cage segments, each of said cage segments including at least two pockets each containing at least one of the axial rolling elements and having two circumferentially spaced end walls having an outer surface,
- a plurality of second radial rolling elements, one of the plurality of second radial rolling elements being located between the end walls of each adjacent pair of the cage segments in contact with the ends walls and radially interposed between the first axial guiding face of the first ring and the first axial guiding face of the second ring, and
- a second row of axial rolling elements located between the second radial raceway of the first ring and the fourth radial raceway of the second ring and radially located between a second axial guiding face of the first ring and a second axial guiding face of the second ring,
- wherein each of the plurality of second radial rolling elements comprises an axial end face and a side wall in contact with the first axial guiding face of the first ring, and
- wherein a diameter of each of the plurality of second radial rolling elements at the side wall is greater than a diameter of the axial end face.
