ABSTRACT:
A gearing system which includes a pair of gears. The tooth profile of the first gear has three portions: a concave portion lying within the dedendum of the first gear, a convex portion lying within the addendum of the first gear, and a transition zone disposed between the concave and convex portions. Similarly, the tooth profile of the mating gear has three portions: a concave portion lying within the dedendum of the mating gear, conjugate to the convex portion of the tooth profile of the first gear; a convex portion lying within the addendum of the mating gear, conjugate to the concave portion of the tooth profile of the first gear; and a transition zone disposed between the concave and convex portions. The pair of gears may be designed such that no contact between meshing teeth is made along the transition zones. The tooth profiles of the gear pair have constant, or nearly constant, relative curvature. Alternatively, due to the shape of the tooth profiles, constant, or nearly constant, contact stress results when the gears are in mesh.
