Abstract

A bearing including a base, a plurality of slots, and a plurality of rollers disposed in the plurality of slots. At least one of the plurality of slots may be configured to retain a first roller and a second roller of the plurality of rollers at different skewing angles. Methods for manufacturing bearings are also described. In an embodiment, a method of manufacturing a bearing includes providing a first plurality of base layers. The first plurality of base layers may include portions of a plurality of slots and portions of a plurality of cooling channels. The method may include inserting a roller in at least one of the portions of the plurality of slots and providing a second plurality of base layers.

First claim

What is claimed:

1. A bearing, comprising:
a base including a plurality of slots;
a plurality of rollers disposed in the plurality of slots;
wherein at least one of the plurality of slots is configured to retain a first roller and a second roller of the plurality of rollers at different skewing angles.

2. The bearing of claim 1 , wherein the first roller includes a first friction radius, the second roller includes a second friction radius, and the second friction radius is larger than the first friction radius.

3. The bearing of claim 2 , wherein the first roller includes a first skewing angle, the second roller includes a second skewing angle, and the first skewing angle is larger than the first skewing angle.

4. The bearing of claim 1 , wherein the at least one of the plurality of slots is configured to retain the first roller, the second roller, and a third roller of the plurality of rollers at different skewing angles.

5. The bearing of claim 4 , wherein the first roller includes a first skewing angle, the second roller includes a second skewing angle, the third roller includes a third skewing angle, the first skewing angle is larger than the second skewing angle, and the second skewing angle is larger the third skewing angle.

6. The bearing of claim 1 , including a third roller, wherein the first roller includes a first friction radius, the second roller includes a second friction radius, the third roller includes a third friction radius, the second friction radius is larger than the first friction radius, and the third friction radius is larger than the second friction radius.

7. The bearing of claim 1 , wherein at least one of the plurality of rollers includes a substantially cylindrical shape.
