ABSTRACT:
The friction drive mechanism has first and second wheels with at least one resilient elastomeric friction ring (O-ring) resiliently engaging on the outer peripheral surface of one of the wheels and against the surface of or against another such ring on the surface of the other wheel. The rings are radially compressed, but axially free. Rotation of the driving wheel causes rotation of the driven wheel through frictional engagement of the resilient elastomeric ring.
