ABSTRACT:
This invention solves a problem encountered in driving conveyor belts where mating belt drive engagement surfaces and sprocket drive surfaces interact to cause wear and to force the belt away from the sprocket. Thus, various shaped modular belt links, provided in accordance with this invention to fit into various conveyor belt configurations, have drive structure appendages extending from cylindrical structure about the pivot rod journalling aperture to form drive surfaces which enter and leave mating sprocket drive channels, with wall surfaces formed between adjacent sprocket teeth in a substantially parallel drive relationship to avoid radially directed forces that drive the belt away from the drive sprocket. Trapezoidal shaped drive surface appendages from the links extend from a generally cylindrical body about the pivot rod in a preferred embodiment. Sprocket drive teeth engage respective ones of two side by side such cylindrical bodies on different end to end links for driving the belt in opposite directions. The cylindrical body has walls of differing thicknesses on opposite sides where intersected by a plane parallel to the belt.
