Abstract
A master link joint for a drive chain is disclosed. The disclosed master link joint includes two master links. Each master link includes a first half link and a second half link that engage each other along mating abutment surfaces. The two master links are disposed on opposite sides of the chain. The first half links are coupled by a pin that traverses the chain and the second half links are coupled by a bushing that traverses the chain. The mating abutment surfaces include a first ramp that meets a second offset ramp at a junction or root. An angle θ defined by the second ramps of the mating abutment surfaces and a line parallel to the rail or bottom pad of the half links ranges from about 45 to about 53°.
