ABSTRACT:
A family of conjugate gear tooth profiles is taught in which the relative curvature is a maximum near center and decreases toward tip and flank, where sliding is greatest. In one embodiment the radii of curvature of the individual profiles are least at the pitch point and increase toward tip and flank. The permissible tooth heights are limited only by top lands and bottom lands; and any tooth-numbers can be used without resorting to unequal addendums, although unequal addendums can be used if desired.
