Abstract: A track assembly may have a chain assembly including a plurality of track links, a traction assembly including track shoes secured to the plurality of track links, a drive sprocket, an idler assembly including an idler and a mount, and a roller assembly including a plurality of rollers and a roller frame. A wear monitoring system may have a wear sensor configured to generate a signal indicative of a current position of a first component of the track assembly, and a controller in communication with the at least one wear sensor, the controller being configured to determine an amount of wear experienced by the track assembly based on the signal. The first component may be configured such that wear of at least a second component causes the first component to move to the current position from a previous position.

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: Disclosed herein is an example track pad having a ground-contacting portion for use in a track-based machine to propel and support the machine across a supporting surface. The track pad may be a track pad that forms a link of a chain forming the track for the track-based machine. The track pad includes a cast body formed of a first alloy steel having a first strength and toughness. The track pad includes a pocket to receive an insert. The insert is formed of a second material comprising a work-hardening alloy such as manganese-steel. The insert is friction welded in place on the track pad and shaped and positioned to contact rollers of the track drive assembly and thereby reduce wear and fatigue on the track pad as a result of contact and force transferred through the roller.

Abstract: A ground-engaging track shoe includes a shoe plate having link-side fixturing surfaces and ground-side fixturing surfaces. The link-side fixturing surfaces and the ground-side fixturing surfaces are raised in profile relative to a link-facing surface and a ground-facing surface, respectively. The fixturing surfaces enable a fixture to clamp the track shoe for support during processing, enabling improvements in maintaining portions of the track shoe flat and reducing part to part variation.

Abstract: An idler assembly includes a hub defining an axis of rotation, a radial direction, and a circumferential direction, and a stepped circumferential surface having a first radially inner face, and a radially outer circumferential surface, forming a raised ridge portion. The radially outer circumferential surface defines an outer diameter, and the first radially inner face defines an inner diameter. A ratio of the outer diameter to the inner diameter ranges from 1.06 to 1.28.
