Inwardly cambered rocker joint for a power transmission chain

摘要

An inwardly cambered rocker joint for a power transmission chain is disclosed. The rocker joint includes a straight pin (7) that defines a rocking surface (25) and engages a first chain link. The rocker joint also includes an inwardly cambered rocker (8) that engages a second chain link and that defines a rocking surface (41) that contacts the pin rocking surface near the ends of the rocker. The inwardly cambered rocker joint provides a stiff joint that reduces tight strand resonance and chain wash.
