In order to decrease the quenching stress in the center of 17Cr2Ni2Mo gear shaft, by adopting the finite element numerical simulation software , the influence of chemical compsotion and quenching condition on the quenching stress in the center of gear shaft has been studied .It turned out that the tensile stress in the center of gear shaft could be decreased effectively by adding a little bit B element , changing the heat transfer interface of gear shaft and raising the temperature of quenching medium .
