A sound reducing carrier roller supports and guides portions of an endless track of a track-type machine as that portion of the track travels between a drive wheel and an idler wheel of the machine. A portion of a rim segment is solidly mounted to the roller shell while a gap is maintained between the rest of the rim segment and the roller shell. A resilient ring is positioned between the segment and the roller shell to reduce noise and impact load on the roller assembly. Conventional track rollers have metal to metal contact between the rim and the roller shell which can generate noise and impact therebetween. The subject roller assembly, with rim segments resiliently mounted, reduces the noise and impact levels.

[ What is claimed is:] [1.]1. A carrier roller assembly for guiding and supporting the endless track of a track-type machine, comprising:a mounting shaft having a first mounting end portion and a second roller supporting end portion;a roller shell having a first end portion, a second end portion, and an intermediate portion, having a raised annular mounting surface with a plurality of threaded holes extending radially therefrom toward the mounting shaft, the roller shell having an axial throughbore;a plurality of bearing assemblies positioned between the roller shell axial throughbore and the mounting shaft second end portion;a plurality of arcuate segments having a first end portion, a second end portion, and an intermediate portion, the segments being circumferentially disposed on the roller shell to define a rim having substantially continuous track bearing surfaces thereon and positioned for the intermediate portion to contact the intermediate portion of the roller shell, the intermediate portion of each rim segment includes a plurality of mounting holes and is releasably attached to the intermediate portion of the roller shell;a first resilient ring around the first end portion of the roller shell to resiliently support the first end portion of the rim segment; anda second resilient ring around the second end portion of the roller shell to resiliently support the second end portion of the rim segment.
