Fatigue Design of PM-Gears Under Consideration of Herzian Pressure with Sliding and Tooth Bending 2005-01-0709

The paper gives an overview of the local stress design concept for gears related both to bending fatigue for the gear teeth and rolling contact fatigue on the gear flanks. Test results are presented for notch fatigue and rolling contact fatigue on specimens as well as for sintered gears manufactured from the quenched and tempered sintered steels (Fe-1.5Mo) + 0.5C and (Fe-4.0Ni-0.5Mo)+ 0.5C, both at a density of ρ = 7.1 g/cm3. The transferability of notch fatigue and rolling contact fatigue data from specimens, test rollers and fatigue test bars, to gears is presented on the basis of local properties.
