Ball bearing having segmented and integral races
First Claim
Patent Images
1. A bearing, comprising:
- a first race including a first segment including a first surface and a second segment including a first surface that aligns with the first segment first surface in an aligned pair of first surfaces, the pair of first surfaces spaced axially relative to an axis;
a second race including second surfaces, each second surface aligned with a respective one of the first surfaces;
balls, each ball located in an annular space between the first and second races;
a cage maintaining each ball in spaced relation and including first tabs circumferentially spaced apart along a circumferential length of the bearing, with each first tab extending axially from a location between respective adjacent balls and in a first lateral direction, each first tab including a first leg directed along a surface of the first segment to retain the first segment, and the cage including second tabs extending in a second lateral direction and configured to retain the second segment to create a gap between the segments.

Abstract
A bearing includes a first race including first and second segments, forming aligned pairs of first surfaces, spaced angularly about an axis; a second race including second surfaces, each second surface aligned with one of the pairs of first surfaces; balls, each ball contacting the surfaces of the first and second races; and a cage retaining each ball and engaging the first and second segments.

12. A bearing, comprising:
-
a first race including a first segment including a first surface and a second segment including a first surface that aligns with the first segment first surface in an aligned pair of first surfaces, the pair of first surfaces spaced axially relative to an axis, the pair of first surfaces comprising a pair of concave surfaces, each with a constant radius of curvature; a second race including concave second surfaces with a constant radius of curvature, each second surface aligned with a respective one of the first surfaces; balls, each ball located between the first and second races; a cage maintaining each ball in spaced relation and including first tabs circumferentially spaced apart along a circumferential length of the bearing, with each first tab extending axially from a location between respective adjacent balls and in a first lateral direction, each first tab including a first leg directed along a surface of the first segment to retain the first segment, and the cage including second tabs extending in a second lateral direction and configured to retain the second segment to create a gap between the segments. - View Dependent Claims (13, 14, 15)

16. A bearing, comprising:
-
a first race including a first segment having a circumferentially extending first surface and a second segment having a circumferentially extending second surface; a second race including a third concave surface having a center of curvature at a first point; and
a fourth concave surface, adjacent to the third surface and having a center of curvature at a second point that is not coincident with the first point;balls, each ball located in an annular space between the first and second races; a cage maintaining each ball in spaced relation and including first tabs circumferentially spaced apart along a circumferential length of the bearing, with each first tab extending axially from a location between respective adjacent balls and in a first lateral direction, each first tab including a first leg directed along a surface of the first segment to retain the first segment, and the cage including second tabs extending in a second lateral direction and configured to retain the second segment to create a gap between the segments. - View Dependent Claims (17, 18, 19)
