Abstract: 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.

Abstract: 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.

Abstract: An offset link track chain may include a plurality of link subassemblies including a first link subassembly and a second link subassembly and a master link assembly removably coupled between the first link subassembly and the second link subassembly. Each link subassembly of the plurality of link subassemblies may include a pair of offset links coupled together. The master link assembly may include a pair of straight links. Each straight link may include a link body having (a) a first aperture positioned proximate a first end, (b) a second aperture positioned proximate a second end, and (c) a threaded fastener. Changing a relative position of the fastener with respect to the link body may change a diameter of the first and second apertures.

Abstract: 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.
