摘　　要：根据坐标变换方法和标准渐开线方程,推导出了一个新的非工作面齿廓修形方程,然后根据该修形方程和SolidWorks建立了齿轮模型.利用有限元分析法对渐开线圆柱齿轮齿廓修形前后的受力情况进行了分析,结果表明修形后的齿轮接触应力比修形前减小了7.01%,修形后的齿根应力比修形前减少了10.95%.According to coordinate transformation method and standard involute equation,we derive a new profile modification equation for non-working face,and then establish a gear model based on the modification equation and SolidWorks.The stress of involute cylindrical gear before and after modification is analyzed by finite element method.The results show that the contact stress of modified gear is 7.01%less than that before modification,and the root stress of modified gear is 10.95%less than that before modification.
