- Abstract
- This paper studied the carburizing of chromium molybdenum steel which the heat treatment effect of gear geometric tolerance, OPD, Runout, the surface hardness, the maximum hardness, the core hardness and the bending fatigue strength were investigated. Firstly, the deformation is observed, and the results of circularity, squareness, OPD and Runout of SCM822, SCM425, and SCM415 are obtained in order. Secondly, in order to investigate the gear hardness, the surface hardness, the maximum hardness and the core hardness of SCM822, SCM425, and SCM415 are obtained; and the surface hardness of SCM822 is about 10% higher than SCM415’s, and about 3% higher than SCM425’s. Thirdly, the fatigue strength of SCM822 is about 10% higher than SCM415’s, and about 7% higher than SCM425’s in the fatigue test results. At last, for the purpose of the minimum deformation of heat treatment, and also the improvement of fatigue strength, the best gear material is SCM822 in this test.
