Abstract
A bearing cage assembly including two different cage halves formed from different materials is disclosed. The first cage half includes a first rim and a first plurality of arms extending from the first rim. The second cage half includes a second rim and a second plurality of arms extending from the second rim. The first cage half and the second cage half are fastened to each other via engagement between a plurality of first retainers of the first cage half with the plurality of second retainers of the second cage half.
Claims17
A bearing cage assembly comprising:
- a first cage half formed from a first material, the first cage half including a first rim and a first plurality of arms extending from the first rim, adjacent arms of the first plurality of arms defining a rolling element pocket half of a first plurality of rolling element pocket halves, a plurality of first retainers defined between the first plurality of rolling element pocket halves;
- a second cage half formed from a second material that is different from the first material, the second cage half including a second rim and a second plurality of arms extending from the second rim, adjacent arms of the second plurality of arms defining a rolling element pocket half of a second plurality of rolling element pocket halves, a plurality of second retainers defined between the second plurality of rolling element pocket halves,
- first axial ends of the first plurality of arms each include a circumferentially extending slot defining a first one of a pocket or a protrusion, the circumferentially extending slot being enclosed in a radially inner direction and a radially outer direction, and second axial ends of the second plurality of arms each include a second one of a pocket or a protrusion, and
- the first cage half and the second cage half are fastened to each other via engagement between the plurality of first retainers with the plurality of second retainers.
