Abstract
A segmented cage for a bearing is provided. The segmented cage provides at least two successive segments each being able to receive at least one rolling element. These segments have inner and outer circumferential faces and adjacent end faces abutting circumferentially one on the other. The adjacent end faces are shaped to obtain only one contact line or contact point between them, the contact point or contact line being distant from the inner and outer circumferential faces.

A bearing, comprising:
- an inner ring having an inner raceway that, when viewed in axial cross section, is formed by a first radially extending axial surface,
- an outer ring having an outer raceway that, when viewed in axial section, is formed by a second radially extending axial surface,
- a plurality of rollers each located between the inner raceway and the outer raceway and making contact therewith, each roller having axial ends,
- a cage formed by at least two successive segments each being able to receive more than one of the plurality of rollers, the segments each having an inner circumferential face and an outer circumferential face, the segments also each having a first end face and a second end face such that the first end face and the second end face of adjacent segments directly abut each other, the segments each having a distance between the inner circumferential face and the outer circumferential face that decreases proximate to the first end face and the second end face, wherein
- the adjacent end faces are shaped to obtain only one contact line or contact point between them to allow pivoting such that the adjacent end faces of the at least two successive segments can pivot relative to each other to allow the adjacent end faces to move simultaneously in a radial direction without substantially changing a circumferential length of the cage, the contact point or contact line being distant from the inner and outer circumferential faces,
- the inner ring, when viewed in axial section, forming a first axially extending radial surface located adjacent to the inner circumferential face of each segment,
- the outer ring, when viewed in axial section, forming a second axially extending radial surface located adjacent to the outer circumferential face of each segment such that a portion of the cage is located between each of the axial ends of each roller and the first and second axially extending radial surfaces.
