Improved form for the profiles of a pair of mating gears having conjugate gear teeth provides substantially constant relative curvature at each point of contact. A differential equation, as well as a more easily solvable approximate solution for the differential equation is given to enable the path of contact of the pair of gears to be determined. The improved tooth form incorporates the major advantages of involute gearing but is able to take substantially higher loading, requires no undercut for gears having a low number of teeth, and provides more intimate contact. The tooth form may be cut with standard machines but has especial utility in powder metal gears since tooth strength can often be increased sufficiently to permit powder metal gears to replace cut gears.
