Abstract
A roller bearing assembly includes an annular outer ring with first and second outer ring shoulders that define a first raceway in the outer ring. An annular inner ring may be disposed substantially concentrically within the outer ring, the inner ring including a base portion and first and second inner ring shoulders that extend from and are integral with the base portion to define a second raceway in the inner ring. A plurality of rolling elements may be arranged between the inner ring and outer ring and within the first and second raceways to rotatably couple the outer ring to the inner ring.
Claims20
A roller bearing assembly, comprising:
- an annular outer ring including first and second outer ring shoulders that define a first raceway in the outer ring;
- an annular inner ring disposed substantially concentrically within the outer ring, the inner ring including a base portion and first and second inner ring shoulders that extend from and are integral with the base portion to define a second raceway in the inner ring;
- and
- a plurality of rolling elements arranged between the inner ring and outer ring and within the first and second raceways to rotatably couple the outer ring to the inner ring.
A method of assembling a roller bearing assembly, the assembly including an outer ring with an outer raceway, an inner ring with an inner raceway, and a plurality of rolling elements for rotatably coupling the outer ring to the inner ring, the method comprising the steps of:
- arranging the rolling elements within the outer raceway of the outer ring;
- heating the rolling elements and the outer ring so as to expand the outer raceway;
- and
- assembling the inner ring concentrically within the outer ring such that the rolling elements are arranged at least partially within the inner and outer raceways.
A roller bearing assembly, comprising:
- an annular outer ring including first and second outer ring shoulders that define a first raceway in the outer ring;
- an annular inner ring disposed substantially concentrically within the outer ring, the inner ring including a base portion and first and second inner ring shoulders that extend from and are integral with the base portion to define a second raceway in the inner ring, wherein the first raceway has a first width and the second raceway has a second width that is greater than the first width;
- and
- a plurality of rolling elements arranged between the inner ring and outer ring and within the first and second raceways to rotatably couple the outer ring to the inner ring, wherein the first ring has a first axis, and wherein the rolling elements have second axis that are substantially parallel to the first axis, and wherein the first and second inner ring shoulders each have a height sufficient to clear the rolling elements during assembly and to maintain the rotatable coupling with the outer ring after assembly.
