ABSTRACT:
A chain drive wherein a chain is formed from a plurality of one-piece roller links each having an enlarged diameter central roller with angularly upwardly and outwardly extending flanges at the opposed ends thereof. A reduced diameter journal projects outwardly from each end of each roller link, with connecting side plates being overlappingly received over the journals of adjacent roller links and retained by spring clips to form a continuous chain.
The central roller of each roller link has a width and diameter for mating reception within circularly recessed bottom lands between the teeth of a complementary formed sprocket wheel. The sprocket wheel also has angularly formed peripheral side walls for mating engagement with the roller link flanges. Further, the recessed sprocket wheel lands blend into flat sprocket tooth faces, or profiles, to allow smooth, substantially roll-free disengagement of the roller links from between the sprocket teeth upon sufficient sprocket wheel rotation.
