A new technique for determining the optimum thickness of the hardened surface layer on gear flanks is presented in the paper. The required hardened layer thickness is determined in relation to the maximum equivalent stress that appears in the layer due to contact with the matching gears. Under favourable lubrication conditions the maximum equivalent stress always appears at a certain depth under the contacting surfaces. The amplitude and position of the maximum equivalent stress in the gear contact region is determined numerically by the finite element method. The computational analyses of the gear contact problem are performed by using the equivalent model of two cylinders that have the same radii as is the curvature radius of the gear flanks at any point on the engagement line. The equivalent cylinders are subjected to real normal and tangential tractions that are determined by the Hertz contact theory. The results from such numerical analyses provide the basis for determination of how the amplitude and position of the maximum equivalent stress depend on the contact pressure, friction and equivalent curvature radius of gear flanks. This relationship is then used for evaluation of the required thickness of the surface-hardened layer, which is needed for prevention of any surface damage, such as pitting, occurring on the gear teeth flanks.
