Abstract

See full text

Several embodiments of a drive pin retention system for mining chains comprise a drive pin, dowel pin, and retainer, wherein the dowel pin is fitted through the holes of a retainer aligned with the holes of the dowel pin and pressed with force so that the tolerance between the dowel pin and retainer is very close. In one embodiment, the retainer is tack welded and then the dowel pin is tack welded to further increase the tolerance and prevent loosening or movement of the retainer due to vibration.
