摘　　要：建立了综合反映阻尼、侧隙、误差和变啮合刚度的非线性齿轮振动模型；编制了计算轮齿动载荷和动载系数的计算机仿真程序；并将幂级数求解变系数微分方程的方法引入齿轮振动方程的求解中，从而不仅能更好地反映齿轮的振动情况，而且提高了计算精度，大大减少了计算时间；还对双圆弧齿轮的螺旋角对动载系数的影响进行了较详细的分析，计算与试验有较好的一致性。In this paper, a non - linear gear vibrition model, synthetically showing the effectS ofdampness,side crack,error and changing meshing stiffness,is set up ; a computer simulation programme,cal culating tooth dynamic load and factors,is given out. In the programme,the power series method for soluingvarying factors differential eguations is tuken into the proceeding of soluing vibration eauations,which notonly can show the vibration situation,but also improve the calculating priseness and decrease the calculatingtime. At last the effects of W-N gear helical angles on dynamic factors are analyzed in detail. There is abetter consistency between calculating result and experiment.
