Abstract: An example bushing has three portions along its radial direction including an inner portion most proximal to a central hole of the bushing, an outer portion most distal from the center hole, and a core portion between the inner portion and the outer portion. The core portion has a hardness that is less than the hardness of the inner portion or the outer portion of the bushing. The bushing may be formed using high carbon steel, which in some cases may be spheroidal cementite crystal structure. A rough bushing may be formed using the high carbon steel, followed by a direct hardening process, and an induction hardening process on the inner surface most proximal to the central hole of the bushing. The induction hardening on the inner surface may harden the outer portion while tempering the core portion of the bushing.

Abstract: A steel track chain component, such as a track bushing, may be formed with a carburized portion, a hardface portion, and a core portion. The core portion may be softer than the carburized portion, which in turn, may be softer than the hardface portion. This configuration of the various portions of the component may allow for relatively high wear resistance of the component, as well as toughness. The core portion may be mostly ferrite crystal structure, while the carburized portion and the hardface portions may include martensitic and/or austenitic crystal structure. The carburized portion may be formed by carburizing the track chain component in a heated and carbon rich environment. The hardface portion may be formed by welding a hardface alloy over at least a portion of the carburized portion.

Abstract: A method of producing a rotating guide component for a track assembly includes fixing at least one wear member to an outer surface of a tubular or annular substrate. The at least one wear member includes an inner portion, and the tubular or annular substrate includes an outer portion. The inner portion is mated to the outer portion, and the wear member is brazed to the tubular or annular substrate.

Abstract: A seal assembly for use in sealing a joint having a first member pivotable about a rotational axis relative to a second member. The seal assembly may include a load ring engaged by the first member, a sealing lip engaging a sealing surface of the second member, and seal ring there between. The sealing lip may have a sealing lip body with a first convex rounded engagement portion of a second member engagement surface positioned to engage the sealing surface when the seal assembly is assembled in the axially-extending seal cavity between the first member and the second member. The second member engagement surface may include additional convex engagement portions, and the sealing lip may include a sealing lip flange extending radially outwardly from the sealing lip body and disposed proximate the sealing surface after assembly.

Abstract: An exhaust system associated with a power source is disclosed. The exhaust system may have an exhaust stack extending from the power source to an exterior of the exhaust system and a moisture collection device disposed within the exhaust stack to collect moisture from the exhaust stack. The exhaust system may also have a moisture entrainment device associated with the moisture collection device to facilitate entrainment of the collected moisture into an exhaust flow of the power source.
