  • Patent number: 11148736
    Abstract: A bushing assembly for a track assembly includes a first end element, a second end element, and a central element positioned between the first end element and the second end element. The central element may be interference fit or positioned between the first end element and the second end element, and the central element may include a greater hardness than the first and second end elements. The first end element, the second end element, and the central element form a bushing with a longitudinal opening extending longitudinally through the bushing.

  • Publication number: 20210284259
    Abstract: A bushing for a track assembly includes a tubular bushing substrate having a longitudinal length and an outer surface. The outer surface includes at least one flat portion. The bushing also includes at least one white iron member. The at least one white iron member includes a flat inner surface, and the flat inner surface of the at least one white iron member is fixed to the flat portion of the outer surface of the tubular bushing substrate.

  • Publication number: 20210101651
    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.

  • Publication number: 20190330729
    Abstract: A method for manufacturing a component is provided. The method includes providing one or more notches on a surface of the component. Further, depositing a coating on the surface to provide a thickness of the coating on the surface, is performed. The method also includes removing, at least partially, the coating from the surface such that the thickness of the coating over the notches is different from the thickness of the coating on the surface adjacent to the notches.

  • Publication number: 20160194039
    Abstract: A link assembly for a track comprises a first side plate, and a second side plate coupled with the first side plate such that proximal surfaces of the first and second side plates are disposed in abutment with one another. The link assembly further includes a wear plate assembly that is coupled to a top face of the first side plate and a top face of the second side plate. The wear plate assembly is formed from a material having a wear resistance greater than a wear resistance of the first and second side plates.

  • Patent number: 9228609
    Abstract: A fabrication method is provided for use in making a component. The fabrication method may include generating a laser beam at a first orientation relative to a wear surface of the component to produce a first laser beam spot having a first characteristic, and feeding a cladding material into the first laser beam spot to produce a cladding layer on the wear surface. The fabrication method may also include generating a laser beam at a second orientation relative to the wear surface of the component to produce a second laser beam spot having a second characteristic, and moving the second laser beam spot along the cladding layer to substantially flatten the cladding layer.

  • Publication number: 20150197295
    Abstract: An undercarriage track joint assembly includes a first link having a first bore at a first end and a second bore at a second, opposite end, and a second link having a first bore at a first end and a second bore at a second, opposite end. A pin may extend between the first and second links, positioned at least partially within the first bores of the first and second links, or partially within the second bores of the first and second links. A bushing may extend between the first and second links, a central axial bore being defined through the bushing. The pin may extend through the central axial bore through the bushing, the pin being coated with a diamond-like carbon (DLC) coating over at least a portion of an outer diameter surface of the pin, the coating providing a contact layer between the outer diameter surface of the pin and an inner diameter surface of the central axial bore through the bushing.
