Idler wheel assembly

A wheel assembly for supporting and guiding a track of a track-type machine comprising:

• a circular body including:
• a central hub portion having an outer surface;
• an annular flange portion integral with the central hub portion having a first side surface and a second side surface;
• a circumferential rim portion having an inner surface and joined to the central hub portion by the first side surface and the second side surface of the annular flange portion;
• a first annular cavity defined by the outer surface of the central hub portion, the first side surface of the annular flange portion, and the inner surface of the circumferential rim portion;
• and
• a second annular cavity defined by the outer surface of the central hub portion, the second side surface of the annular flange portion, and the inner surface of the circumferential rim portion;
• a sound dampening member disposed in one of the first annular cavity and the second annular cavity, wherein the sound dampening member is insertable into the first annular cavity or the second annular cavity as one piece;
• and
• a retainer plate positioned adjacent to the sound dampening member,
• wherein the retainer plate is attached to the central hub portion of the circular body by welding at a first welded portion and attached to the circumferential rim portion of the circular body by welding at a second welded portion, and
• wherein the sound dampening member includes a first annular chamfered surface at an inner circumferential surface thereof to accommodate the first welded portion and a second annular chamfered surface at an outer circumferential surface thereof to accommodate the second welded portion.
