This paper deals with the bending fatigue strength of sintering spur gears. The test specimens are used to sintering spur gear to be consisted of Fe-C-Ni-Mn and SCM415 spur gear. The fatigue test at a constant stress amplitude is performed by using an electrohydraulic servo-controlled pulsating tester. The S-N curves are obtained and the enhancement of fatigue strength due to carburized treatment is clarified, Accordingly, this study presents the fatigue strength of sintering spur gear, SCM415 spur gear and carburized gears of them. The strength enhancement due to the carburized treatment is discussed.
