CONVEYOR LINK CHAIN WITH UNIVERSAL COUPLING JOINT

摘要

A conveyor chain (22) with a universal coupling joint connecting consecutive chain links (30). The joint includes a joint member (38) unitarily molded with a first link body engaged by a separately formed joint element insertable into a second adjacent link body (21) to link the two link bodies at the joint. The insertable joint element (46) may be made of a different material from the link body. The joint member has a convex or concave spherical bearing surface (52) that engages a complementary concave or convex bearing surface on the joint element for universal pivoting.
