Abstract
A method of producing a rotating guide component for a track assembly includes fixing at least one wear member to an outer surface of a tubular or annular substrate. The at least one wear member includes an inner portion, and the tubular or annular substrate includes an outer portion. The inner portion is mated to the outer portion, and the wear member is brazed to the tubular or annular substrate.
Claims20
A track roller for a track assembly, comprising:
- a tubular roller substrate having a longitudinal length and an outer surface, wherein the outer surface includes at least one flat portion or at least one curved portion, the tubular roller substrate further comprising outer flanges on opposite ends thereof, the outer flanges configured to contact outer surfaces of track links of the track assembly such that the track links are disposed between the outer flanges;
- and
- at least one wear member, wherein the at least one wear member includes an inner surface comprising a flat inner surface or a curved inner surface, and the at least one wear member is brazed to the outer surface of the tubular roller substrate with the at least one flat portion of the tubular roller substrate mating with the flat inner surface of the at least one wear member, or at least one curved portion of the tubular roller substrate mating with the curved inner surface of the at least one wear member,
- wherein the at least one wear member comprises an outer surface opposite the inner surface, wherein the outer surface of the at least one wear member is an arcuate surface, wherein the arcuate surface of the at least one wear member is configured to contact top surfaces of the track links.

A track roller for a track assembly, comprising:
- a tubular roller substrate having a longitudinal length and an outer surface, wherein the outer surface includes at least one flat portion, wherein the tubular roller substrate further includes flanges configured to contact outermost surfaces of track links of the track assembly;
- and
- at least one wear member, wherein the at least one wear member includes a flat inner surface, and the at least one wear member is brazed to the outer surface of the tubular roller substrate with the at least one flat portion of the tubular roller substrate mating with the flat inner surface of the at least one wear member,
- wherein the at least one wear member comprises an arcuate surface configured to contact a surface of the track links other than the outermost surfaces.
