Generalization/Specialization and Role in Object Oriented Conceptual Modeling

A conveyor structure for use where accuracy is desired between succeeding portions of the conveyer and, at the same time, wear is to be minimized. The conveyor comprises a plurality of interconnected links. Each link comprises a body having at least two longitudinally spaced openings. A bushing is resiliently mounted in each opening by a relatively resilient but solid plastic molded in situ between the periphery of the bushing and the opening. The links are interconnected by pins extending through the aligned bushings of succeeding links and the pins engage a rotary element such as a sprocket to produce a driving engagement between the rotary element and the conveyor.
