Claims13
A bearing assembly comprising:
- an outer ring;
- an inner ring;
- a plurality of rolling elements disposed between the outer and inner rings;
- a cage assembly comprising;
- a first cage comprising:
- a first cylindrical disc body having a first material thickness;
- a first plurality of flat axial projections extending from the first cylindrical disc body in a first axial direction and having the first material thickness;
- each of the first plurality of flat axial projections formed from a displaced portion of the first disc body, leaving a first plurality of holes in the first body substantially the same geometry as the first plurality of flat axial projections;
- a second cage comprising:
- a second cylindrical disc body having a second material thickness;
- a second plurality of flat axial projections extending from the second cylindrical disc body in a second axial direction and having the second material thickness;
- each of the second plurality of flat axial projections formed from a displaced portion of the second disc body, leaving a second plurality of holes in the second body substantially the same geometry as the second plurality of flat axial projections;
- and
- the first plurality of flat axial projections of the first cage and the second plurality of flat axial projections of the second cage oriented towards each other;
- the first plurality of flat axial projections of the first cage are disposed between adjacent rolling elements on a first axial end of the rolling elements;
- and
- the second plurality of flat axial projections of the second cage disposed between adjacent rolling elements on the second axial end of the rolling elements.
