ABSTRACT:
A track chain has a master link joining together a pair of axis-defining shafts. This master link has a pair of like link parts each mounted on a respective shaft and pivotal about its axis. The link parts have axially confronting inner faces formed with meshing teeth each having an inner flank that faces back toward the respective shaft, that flatly engages the inner flank of the respective tooth of the other link parts, and that forms with the axis of the respective shaft an acute angle. Thus forces urging the shafts radially apart have at these inner flanks have force components urging the parts axially together. No bolts extending axially between the two parts are necessary and the respective track shoe can be bolted to both of the parts of the master link so as to inhibit relative pivoting thereof.
