Cage with parallel pockets for rolling bearing

摘要

A cage for a rolling bearing including a plurality of cage segments is provided. Each segment has a first set of pockets for a first set of rollers, and a second set of pockets for a second set of rollers. The axes of the pockets of the first set of pockets are parallel with each other and the axes of the pockets of the second set of pockets are parallel with each other.

主权项

1. A radial cage for a rolling bearing comprising:
a plurality of cage segments, the plurality of cage segments being discrete individual components configured to be arranged end-to-end along a circumference to collectively serve as the radial cage for the rolling bearing, each of the plurality of cage segments comprising:
a first rib and a second rib which are spaced from each other and connected by a plurality of connecting portions, the first and second ribs each having a radially inner surface and a radially outer surface, the radially inner surface facing radially toward an axis of rotation and the radially outer surface facing radially away from the axis of rotation,a first set of pockets for a first set of rollers, anda second set of pockets for a second set of rollers, wherein the axes of the pockets of the first set of pockets are parallel with each other, the axes of the pockets of the second set of pockets are parallel with each other, wherein the first and second sets of pockets are delimited by the plurality of connecting portions which each form at least one rolling surface such that each of the at least one rolling surface extends radially inwardly toward the axis of rotation from the first and second ribs and also extends radially outwardly away from the axis of rotation from the first and second ribs, at least one of the plurality of connecting portions forming two rolling surfaces for adjacent rollers wherein the two rolling surfaces of the at least one of the plurality of connecting portions are configured to engage rollers having non-parallel axes of rotation, each of the plurality of connecting portions having an axial width which decreases the farther it radially extends past the first and second ribs.
