Abstract:
1. A wheel resurfacing system for resurfacing a worn track wheel substantially to an original profile, comprising: a support unit holding the worn track wheel, the worn track wheel having a circumferential surface defining a flange and a tread surface; a welding unit maintained in spaced relation to the worn track wheel on said support unit, said welding unit applying a welding material to the worn track wheel during relative angular displacement between said welding unit and the worn track wheel; a controller coupled to at least one of said support and welding units, said controller configured to selectively actuate said welding unit and concurrently adjust axial and radial displacement relative to a track wheel center between said welding unit and the track wheel, said controller thereby actuating said welding unit over a plurality of revolving passes of the track wheel to adaptively aggregate a plurality of annular beads of the welding material radially and axially displaced along a curved profile of the circumferential surface and form a welded layer of varied thickness thereon, the welded layer thereby forming a curvilinear profile tapered away from the flange; and, a surface processing device selectively applied to the welded layer to form a substantially uniform surface to reconstitute the worn track wheel to the original profile.
