摘要

FIELD: transport. ^ SUBSTANCE: invention relates to variable-diameter or offset sprockets. Drive sprocket features larger diameter apex bent opposite direction of motion. Note here that larger-diameter apex is sharpened at intersection of perpendicular moving from smaller-diameter apex. Center of rotation may be shifted along vertical and/or horizontal axes. ^ EFFECT: higher sprocket drive efficiency. ^ 11 cl, 4 dwg
