Abstract
A multiple guidance cage for a bearing includes an axis, and a cylindrical ring extending around the axis. The cylindrical ring includes a plurality of partial spherical cutouts distributed circumferentially about the cylindrical ring, and a plurality of segments. Each one of the plurality of segments is disposed between a pair of the plurality of partial spherical cutouts. Each of the plurality of partial spherical cutouts is arranged for receiving a rolling element, and each one of the plurality of segments includes a distal end with a radial bump. In an example embodiment, each one of the plurality of segments is axially recessed between the pair of the plurality of partial spherical cutouts.
Claims17
A bearing comprising:
- a multiple guidance cage comprising an axis and a cylindrical ring extending around the axis, wherein the cylindrical ring comprises
- a plurality of partial spherical cutouts distributed circumferentially about the cylindrical ring, each of the plurality of partial spherical cutouts arranged for receiving a rolling element;
- and
- a plurality of segments, each one of the plurality of segments disposed between a pair of the plurality of partial spherical cutouts and comprising a distal end with a radial bump;
- a plurality of balls operating as rolling elements, each one of the plurality of balls disposed in a one of the plurality of partial spherical cutouts;
- an outer ring disposed radially outside of the multiple guidance cage, the outer ring comprising an outer ball race;
- and
- an inner ring disposed radially inside of the multiple guidance cage, the inner ring comprising an inner ball race;
- wherein the outer ring comprises an inner cylindrical surface with an inner diameter, and
- wherein the multiple guidance cage comprises an outer diameter measured at the radial bump that is less than the inner diameter.
