Abstract
Inspired from some gears with heavy power transmission in practical usage after serious plastic deformation in metallurgical industry, we believe that there must existed some kind of gear profile which is most suitable in both the contact and bending fatigue strength. From careful analysis and deep going investigation, we think that it is the profile of equal conjugate curvature with high order of contact, and analyzed the forming principle of this kind of profile.Based on the second curve and comparative analysis of fourth order curves, combined with Chebyshev polynomial terms of higher order contact with tooth contact stress,formula derived.Note high exposure in the case of two extreme point of stress and extreme positions and the derived extreme contact stress formula.Finally, a pair of conjugate gear tooth profile curvature provides specific contact stress calculation.
Key word: gear stress contact of high-level
