Abstract

Abstract

The experimental investigation on the reliability of gear-tooth fatigue strength of hardened and tempered steet 40Cr is dealt with. Four loading stress levels (6 samples each) are conducted. Based on the test data, a R-S-N curve and the related equation were fitted. Finally the limiting bending fatigue strength of the 40Cr gear-tooth under different reliabilities are evaluated.
