摘要
以直齿轮齿廓修形量、齿廓修形高度、齿廓修形幂指数、齿向修形量这4个基本参数为变量,取动态传递误差峰峰值、最大接触应力加权最小为优化目标,使用有限元方法计算接触应力;考虑轴承、轴、陀螺力等因素的影响,使用有限元节点法计算动态传递误差,以Kriging方法为优化方法,构建一种新的直齿轮复合修形设计方法,并通过一对实际齿轮传动来验证计算模型。研究结果表明:用所提出的方法优化后得到齿轮动态传递误差峰峰值相对于优化前降低75.98%,最大接触应力降低21.48%,这表明所提出的复合修形优化方法对齿轮修形设计具有参考与应用价值。
Taking four basic parameters of the spur gear modification as the variables,and taking the peak-to-peak value of the dynamic transmission error and the maximum contact stress weighted minimum as the optimization goal,the contact stress was calculated using the finite element method.Considering the influence of factors such as bearings,shafts and gyro,etc,the finite node element method was used to calculate the dynamic transfer error.Taking the Kriging method as the optimization method,a new spur gear compound modification design method was constructed.A pair of actual gear transmissions was used to verify the method.The results show that the peak to peak value of the dynamic transmission error of the gear after optimization obtained by the present method is reduced by 75.98%and the maximum contact stress is reduced by 21.48%,which indicates that the proposed optimization method of compound modification has reference and application value for gear modification design.
