Gear tooth failure modes
WebOct 30, 2024 · During contact moments (gearing), the superficial damage accumulation is based on the transmitted power conjugation, the gears geometry and the properties of … WebOct 1, 2006 · Tooth bending fatigue is one of the most common modes of fatigue failure in gears. Since the maximum tensile stresses occur at the root radius on the active flank of the gear tooth, gear-tooth failure from bending fatigue generally results from a crack originating in the root section of the gear tooth [1], [2]. The whole tooth, or a part of the ...
