Abstract
A split master link includes first and second separable sections which are joined together at an overlapping joint comprising a series of interengaged teeth located centrally in the link mass. The link sections have confronting surfaces forming continuations of the opposite ends of the tooth racks of the sections and in one embodiment, one of each set of confronting surfaces at an end of the tooth racks is stepped so that a relief area extends from the tooth rack towards a side of the link through a distance of approximately three-fourths of the disance of the tooth to the side of the link. In a second embodiment, the pair of confronting surfaces at each end of the tooth racks are arranged in converging relationship so that they converge at a side of the track link. A relief area is thus formed at the opposite ends of the tooth racks and each relief area extends to an adjacent side of the link. Relief areas of both the embodiments serve to greatly decrease the cyclic strain that the track link would experience for a given load as compared to a track link having no such relief areas.
