ABSTRACT:
Gear tooth profiles that afford greater torque capacity than is obtainable from involute gears of corresponding size and materials. Maximum contact stress is reduced by using profile curves that give exceptionally long radii of relative curvature at the pitch point, and interference problems with such profiles are avoided by utilizing a two-segment line of action. When the gears are not carrying a torque load each tooth profile in the transverse plane passes successively through two points of contact but are out of contact at points in between. As the torque load increases, the two contact zones widen until they coalesce.
