为节省钢材 ,降低成本 ,减小减速器的质量 ,以减速器齿轮的体积最小为优化设计目标 ,以设计变量的约束函数来保证减速器的性能指标 ,用混合罚函数法MPOP优化程序对CYJ1 4—6— 89HF抽油机的双圆弧齿轮减速器的齿轮参数进行了优化设计。设计中选取低速级齿轮模数为 8或 9时 ,得到两组满足强度条件的优化结果 ,齿轮材料分别减少 1 7 7%和 2 9 97%。生产了优化设计的双圆弧齿轮减速器 80多台 ,节省材料费用近 40万元 ;一些减速器已投入现场使用 ,效果良好 In order to save the steel, reduce the cost and reduce the quality of the reducer, the minimum design of the reducer gear is the optimal design objective. The constraint function of the variable is used to ensure the performance of the reducer. The mixed penalty function method 4-6-89HF pumping unit double arc gear reducer gear parameters were optimized. In the design, when the modulus of low-speed gears is selected as 8 or 9, two sets of optimization results that meet the strength conditions are obtained. The gear materials are reduced by 177% and 297% respectively. Produced more than 80 double-arc gear reducer with optimized design, saving material cost nearly 400,000 yuan; some reducer has been put into use in the field, the effect is good
