摘要：

The life of bevel gear dies is determined by its stress state mainly. During the forging, the die teeth fractured and the bottom corner cracked in a few times. Finite Element Analysis (FEA) was employed to investigate the reason of failure. The results show that the tip fracture and the bottom corner crack mainly resulted from excessive tensile stress. In accordance with the FEA results, the non-plane parting face was changed into plane parting face and the radius of bottom hole was enlarged, The FEA result proves that the modification can greatly reduce stress concentration and the application proves that the modification can effectively solve the premature failure of the die.
