A machine system includes a roller frame and a roller assembly mounted to the roller frame. The roller assembly includes first and second clamping collars positioned upon a roller shaft and each including a lower and an upper collar section. Fasteners clamp the lower and upper collar sections to the roller shaft to form static seals. The clamping collars may be formed with splitlines to enable the clamping collars to deform so as to simulate interference fits with the roller shaft.

A track link rail surface and roller interface includes a first roller including a cylindrical configuration defining a radial direction, a longitudinal axis, a circumferential direction, and a plane containing the radial direction and the longitudinal axis. The first roller includes a first track link rail engaging surface including a first concave arcuate surface defining a first concave radius of curvature. The interface includes a first track link including a first track link rail surface including a first convex arcuate surface defining a first convex radius of curvature that is less or equal to the first concave radius of curvature.

Spalling resistant track link and roller interface

A clamping master track link includes a body that defines a first bore and a second bore, a first aperture disposed between the first bore and the second bore, a second aperture disposed between the first aperture and the second bore, a first strut with a first gap disposed between the first aperture and the second aperture, a second strut with a second gap disposed between the first aperture and the first bore, and a bridge disposed between the second aperture and the second bore. The first bore defines a cylindrical bore surface that is at least partially textured.

A master link for a track chain is disclosed. The master link may include a link body extending from a first end to a second end and a plurality of apertures extending through the link body. The plurality of apertures may include a first aperture positioned proximate the first end, a second aperture unconnected to the first aperture and positioned proximate the second end, and a third aperture arranged between the first and second apertures. A first gap may extend between and connect the third and second apertures. The master link may also include a threaded first fastener that is configured to extend through the link body across the third aperture.

A clamping master track link comprises a body that defines a first bore and a second bore, a first aperture disposed between the first bore and the second bore, a second aperture disposed between the first aperture and the second bore, a first strut with a first gap disposed between the first aperture and the second aperture, a second strut with a second gap disposed between the first aperture and the first bore, and a bridge disposed between the second aperture and the second bore.

Undercarriage clamping master track link

A master link joint for a drive chain is disclosed. The disclosed master link joint includes two master links. Each master link includes a first half link and a second half link that engage each other along mating abutment surfaces. The two master links are disposed on opposite sides of the chain. The first half links are coupled by a pin that traverses the chain and the second half links are coupled by a bushing that traverses the chain. The mating abutment surfaces include a first ramp that meets a second offset ramp at a junction or root. An angle &#x3b8; defined by the second ramps of the mating abutment surfaces and a line parallel to the rail or bottom pad of the half links ranges from about 45 to about 53&#xb0;.

A construction machine includes a chassis, at least one continuous track supporting the chassis, at least one rim operatively associated with the continuous track, a shaft rotatably associated with the rim, and a collar operatively associated with the shaft and a guard plate. The collar has a variably angled face interfacing with the rim, and a labyrinth is formed between the collar and the rim via the variably angled face.
