Abstract: 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.

Abstract: An idler group is disclosed for a mobile machine having a tracked undercarriage with an endless track. The idler group may include a retainer disposed on an axle and within an opening in an idler. The retainer may be configured to achieve an interference fit with the idler sufficient to hold the retainer within the opening of the idler during operation of the mobile machine. In another embodiment, a retaining ring may be disposed within a channel formed in the idler and may contact the retainer. In yet another embodiment, a swaged connection may be formed between the idler and the axle.

Abstract: A work machine, such as a tractor or skid steer, has a motion sensor attached to a segment of a continuous ground-engaging track in its undercarriage. The motion sensor generates motion data indicative of a change in motion for the track segment as the track rotates around a track assembly. An electronic controller for the work machine receives and evaluates the motion data, first to identify a location of the track segment within the undercarriage and then to compare the motion data with expected motion data for the track segment under normal track tension. Motion data outside a range of the expected motion data indicates an abnormal sag in the track, causing the electronic controller to generate an alert for adjustment of the track tension.

Abstract: A roller mounting assembly for a ground-engaging track system includes a frame, and a roller block coupled to the frame and including a shaft support surface extending through the roller block. The roller mounting assembly further includes a damper resiliently deformable, relative to the roller block, to dampen loads transmitted between the roller block and the frame. Embodiments of a roller block assembly and a damping shim assembly are also disclosed.

Abstract: 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.
