Abstract
A gearing system which includes a pair of conjugate gears. The tooth profile of the first gear lies entirely within the pitch circle of the first gear, and the tooth profile of the mating gear lies entirely outside the pitch circle of the mating gear. The profile of the first gear is fully or partially concave, and the tooth profile of the mating gear is fully or partially convex. The profiles of the conjugate gear pair may have constant, or nearly constant, relative curvature. Alternatively, due to the shape of the profiles, constant, or nearly constant, contact stress results when the gears are in mesh.
