Abstract:

A rim includes a wall, a first annular projection, and a second annular projection. The wall has a first end and a second end. The first end includes a first opening, and the second end includes a second opening that communicates with the first opening to define a bore for a shaft of a track roller. The first annular projection and the second annular projection, which are configured to engage a track, extend radially from the wall. The first annular projection includes a first flange that is configured to constrain movement of the track in a first axial direction. The first flange includes a plurality of notches. The second annular projection includes a second flange that is configured to constrain movement of the track in a second axial direction that is opposite to the first axial direction.
