Abstract
A roller bearing construction that eliminates the need for a cage or separator to align and position the rollers. Gear teeth formed on the rollers and races function as spaced apart planetary gear sets to insure correct roller alignment and spacing, reducing friction and wear and increasing load capacity.
Claims30
In a roller bearing having a pair of circumferentially continuous races,
- a plurality of rollers in rolling engagement with said races,
- each of said rollers having a load bearing portion formed to a surface of revolution and a pair of spaced apart toothed portions,
- each of said races having a load bearing portion formed to a surface of revolution and a toothed portion, one of said races having two spaced apart toothed portions in meshing engagement with the toothed portions on said rollers,
- each of said surfaces of revolution having substantially straight generating elements,
- the pitch surface of each of said toothed portions containing straight-line extensions of said straight generating elements, the teeth of one of said toothed portions being formed to profiles contacting their mating tooth profiles substantially at the pitch line.

In a roller bearing having a pair of circumferentially continuous races,
- a plurality of rollers interposed between said races,
- each of said rollers having a load bearing portion formed to a surface of revolution and a toothed portion,
- each of said races having a load bearing portion formed to a surface of revolution and a toothed portion,
- each of said surfaces of revolution having substantially straight generating elements,
- the pitch surface of each of said toothed portions containing straight line extensions of said straight generating elements, the toothed portion of one of said races having teeth the active profiles of which are entirely on one side of the pitch surface of said toothed portion.
