Abstract
A track roller bearing and method of manufacture thereof is presented in which the axial thrust bearing elements are integral inclined opposed surfaces formed on the inner and outer races of the track roller bearing. The inner race is swaged to form the inclined axial bearing surfaces on the inner race after the races are assembled. A self-lubricating material is bonded to the inner race, including the axial bearing inclined surfaces thereof, after the inner and outer races are assembled and the axial bearing surfaces are formed.
Claims12
A track roller bearing comprising:
- an inner race having an annular load bearing surface around an axis and extending in the direction of and being coaxial with the axis;
- first and second inclined surfaces extending from said inner race at opposite ends of said annular load bearing surface of said inner race, said surfaces being integral parts of said inner race and being inclined away from said axis;
- an outer race having an annular load bearing surface extending in the direction of and being coaxial with said axis, said annular load bearing surface of said outer race facing and being spaced from said annular load bearing surface of said inner race;
- first and second inclined surfaces extending from said outer race at opposite ends of said annular load bearing surface of said outer race;
- said first and second inclined surfaces of said outer race being opposed, respectively, to and spaced from said first and second inclined surfaces of said inner race;
- and
- a layer of self-lubricating material affixed to said annular load bearing surface and said first and second inclined surfaces of said inner race.
