Abstract
A rolling bearing includes an inner ring, an outer ring, a plurality of rolling elements disposed between the inner ring and the outer ring, and a plurality of cage segments separating circumferentially adjacent ones of the plurality of rolling elements. Each of the cage segments has an axial bridge portion and side plates at axially opposite ends of the bridge portion, each of the side plates having a convex end and a concave end circumferentially spaced from the convex end. The convex end of a first one of the side plates contacts the concave end of a second one of the side plates.
Claims16
A rolling bearing comprising:
- at least one inner ring and at least one outer ring,
- wherein between the at least one inner ring and the at least one outer ring a number of rolling elements are arranged,
- wherein the rolling elements are held by a cage,
- wherein the cage is made of a number cage-segments including a first cage segment and a second cage segment,
- wherein each cage segment comprises two rolling element contact surfaces,
- wherein each cage segment includes at least one attachment element,
- wherein each cage segment includes in at least one axial end region a side plate partially covering an end side of one of the rolling elements, the side plate having a convex end edge and a concave end edge spaced from the convex end edge in a circumferential direction, and
- wherein the concave end edge of the side plate of the first cage segment non-interlockingly abuts the convex end edge of the side plate of the second cage segment.
A rolling bearing comprising:
- an inner ring;
- an outer ring;
- a plurality of rolling elements disposed between the inner ring and the outer ring;
- and
- a plurality of cage segments separating circumferentially adjacent ones of the plurality of rolling elements, each of the cage segments comprising an axial bridge portion and side plates at axially opposite ends of the bridge portion, the side plates overlying axial ends of the rolling elements, each of the side plates having a convex end and a concave end circumferentially spaced from the convex end,
- wherein the concave end of the side plate of the first cage segment non-interlockingly abuts the convex end of the side plate of the second cage segment.
