This paper presents a study on residual stresses and bending fatigue strengths of case-carburized thin-rimmed spur gears with web arrangement. A heat conduction analysis and an elastic-plastic stress analysis during the case-carburizing process of the thin-rimmed spur gears with web arrangement were carried out for various case-carburizing conditions by means of the case-carburizing simulator developed by the authors. Bending fatigue tests were carried out for different case-carburized thin-rimmed spur gears with web arrangement. Effects of the case depth, carburized part and web structure on the residual stress and the bending fatigue strength were determined. Furthermore, results for the case-carburized thin-rimmed spur gears with web arrangement were compared with those for solid gears.
