To enhance the strength of gears for transmission. generally caburizing heat treatments is applied. But there are some problems in this technology - the distortion of gears during heat treatment process.<br/> and the discontinuity of manufacturing process. For these reasons, the high frequency induction hardening process is widely used. This method is one of the surface hardening process to improve<br/> the wear resistance and fatigue life of the machine components.<br/> In this study, to compare the bending fatigue strength of caburized gear with that of induction hardened gear, bending fatigue testing of gears with two different cases was performed by using an electrohydraulic servo-controlled fatigue testing machine and double tooth bending fatigue test fixture.<br/> Fatigue life distributions at constant stress levels were established directly from fatigue data. For gear design, the fatigue strength distribution at specified life is more important. To obtain the fatigue strength distribution, fatigue life distribution was transformed statistically. Reliability of bending fatigue strength was estimated by P-S-N curves and Weibull distribution.<br/>
