Abstract

According to one or more embodiments, a bushing (100) for a track assembly (12) includes: a tubular bushing base (110) having a longitudinal length and an outer surface (112); and at least one white iron member (120) secured to an outer surface (112) of the tubular bushing base.

Description

technical field [0001] The present disclosure relates generally to bushings, and more particularly to bushings for track assemblies of machines. Background technique [0002] Track-type machines typically utilize track chains on each side of the machine that engage the ground surface during propulsion of the machine. A plurality of individual links are pivotally coupled via a bushing and pin arrangement to form a track chain. A sprocket driven by the machine's engine engages the bushing and translates the chain about one or more idler gears. As the chain translates, the connected links engage the ground surface below the machine, such as via the coupled track shoes, and propel the machine over the surface. The track chain can be a straight chain with alternating inner and outer links, or it can be an offset link chain where all links are the same. In both types of track chains, the elements wear over time, particularly the bushings that continuously engage the sprockets t...
