Drive gear having an internal flexible coupling

The gear system comprising a drive gear and a driven gear in mash with said drive gear;

• said drive gear comprising an inner annular member and an outer annular member;
• said inner annular member having plural outwardly extended walls, and said outer annular member having intervening inwardly extending walls forming plural circumferentially spaced compartments between said members;
• said inner and outer members are concentrically arranged around the rotational axis of said drive gear;
• said inner and outer members having mating circular bearing surfaces concentric around said drive gear rotational axis and compressible plug means in each said compartment for establishing resilient connections between the inner annular member and the outer annular member said inner and outer members being concentric around said drive gear axis irrespective of load forces exerted thereon by said compressible plug means and said driven gear;
• said outer annular member having an internal surface extending normal to said drive gear rotational axis to form one end wall of each said compartment;
• said inner annular member being axially telescoped within said outer member so as to abut said internal surface;
• and an annular cover spanning said inner and outer annular members in axial spaced rotation to said internal surface, whereby said cover forms an other end wall of each said compartment.
