Abstract: A track assembly for a track-type machine is disclosed. The track assembly includes inner and outer track links. A rotatable bushing is positioned about a track pin and a sleeve bearing is positioned about the track pin. A first seal member is disposed between an inner track link and the rotatable bushing and a second seal member is disposed between inner and outer track links. A first thrust ring is engaged with the rotatable bushing and a second thrust ring is engaged with the sleeve bearing. A first contact member is engaged with the first seal member and a second contact member is engaged with the second seal member. The first and second contact members are configured to inhibit wear of the first and second seal members.

Abstract: A lobed bushing (72) is provided for a track assembly (16) of a track-type machine (10). The track assembly includes a first chain (40) and a second chain (42) coupled together with a track pin (70). The bushing, defining a longitudinal axis (A), includes a central bore (78) oriented along the longitudinal axis and extending from a first end (80) of the bushing to a second end (82) of the bushing for receiving the track pin. The bushing includes a first lobe (96) positioned at a first location (110) about the longitudinal axis and a second lobe (112) positioned at a second location (114) about the longitudinal axis that is less than about 180° from the first location. The first end of the bushing has a substantially cylindrical shape.

Abstract: A bushing for use in a tracked undercarriage of a track-type machine includes a first end and a second end disposed opposite the first end. An outer surface extends between the first end and the second end and is shaped to engage a sprocket of the tracked undercarriage. The bushing also includes an annular inner surface disposed between the first end and the second end defining an internal cavity shaped to receive a track pin. An innermost portion of the inner surface forms a crown having a radius less than or equal to (PL2)/[(24E pDRBush 4)(l-cos[(PL)/(16EpDRBush 4))] where L is the length of the bushing, P is the weight of the track-type machine, E is the Modulus of Elasticity of the bushing, and RBush is a radius of the innermost portion of the annular internal cavity.
