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.

A rim for a track roller, the rim comprising:
- a wall having a first end and a second end that is opposite to the first end, wherein
- 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 the track roller;
- a first annular projection extending radially from the wall to engage a first edge of a track, the first annular projection including:
- a first exterior flange having a first plurality of exterior notches, wherein
- the first plurality of exterior notches together form an undulating, annular shape on the first exterior flange,
- the first exterior flange is configured to constrain movement of the track in a first axial direction, and
- the first exterior flange is formed from a single, integral piece of material;
- and
- a second annular projection extending radially from the wall to engage a second edge of the track, the second annular projection including:
- a second exterior flange that is configured to constrain movement of the track in a second axial direction that is opposite to the first axial direction.
A rim segment for a track roller, the rim segment comprising:
- a wall having a first end and a second end, wherein
- 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 the track roller;
- and
- an annular projection extending radially from the wall, the annular projection including:
- a base portion that is configured to contact an edge of a track, and
- an exterior flange that is configured to constrain axial movement of the track, wherein
- the exterior flange includes a plurality of notches that together form an undulating, annular shape on the exterior flange, and
- the exterior flange has a diameter that is greater than a diameter of the base portion.
A rim segment for a track roller, the rim segment comprising:
- a substantially cylindrical wall having a first end and a second end;
- and
- an annular projection extending radially from the substantially cylindrical wall, the annular projection including:
- a base portion that is configured to contact an edge of a track, and
- an exterior flange that is configured to constrain axial movement of the track, wherein
- the exterior flange includes a plurality of notches that together form an undulating, annular shape on the exterior flange, and
- the exterior flange has a diameter that is greater than a diameter of the base portion;
- and
- wherein the rim segment is made of a single, integral piece of material.
