摘要： A ground-engaging track shoe in a track joint assembly includes a shoe plate having bolt holes extending through a middle plate section between a planar link-bolting surface and a ground-contact surface. A weight relief channel is formed in the middle plate section upon a link-bolting side of the track shoe, and extends inwardly from the planar link-bolting surface. The weight relief channel is arranged between a forward bolt hole set of the bolt holes and a back bolt hole set of the bolt holes in a fore-aft direction.

摘要： A face seal assembly and rotating assembly for a track machine are disclosed. The face seal assembly includes a first seal ring, an annular housing, a second seal ring, and a bias member. The first seal ring is fixed to a rotating part for rotation about an axis. The first seal ring includes a seal face and a radially outer surface press-fittingly confronting an annular bore in the rotating part. The annular housing is spaced axially inward from the first seal ring and rotationally fixed. The annular housing includes an axially inner surface and a radially inner surface. The second seal ring is disposed axially between the first seal ring and the annular housing. The second seal ring includes a seal face confronting the seal face of the first seal ring. The bias member is compressed between the annular housing and the second seal ring.

摘要： A roller assembly is disclosed. The roller assembly may have a roller shell. The roller shell may have a bore. The roller assembly may also have a substantially cylindrical shaft. The shaft may extend from a shaft proximate end to a shaft distal end. The shaft may be disposed within the bore. The roller assembly may also have a first collar disposed between the shaft proximate end and the roller shell. The first collar may be interferingly engaged with the shaft. The roller assembly may further have a second collar disposed between the shaft distal end and the roller shell. The second collar may also be interferingly engaged with the shaft.
