| Abstract: | The experimental investigation of gear-tooth bending fatigue property for 18Cr2Ni4WA steel Gear with Carburization-Quench Hardening was reported. The grouping test method at three constant stress levels was applied for short life-span areas. The tested data were the processed with statistic method. The exact R-S-N curves were thus fitted as a result, the values of limit of bending fatigue under various reliabilities were gained. |
