摘  要:为对两级渐开线圆柱齿轮减速器的齿轮结构进行优化设计,根据齿轮强度计算标准和机械结构优化设计的相关理论,分析了对齿轮接触强度和弯曲强度较大有影响的参数,以最小中心距为目标函数,以齿轮强度、尺寸等为约束条件,建立了两级渐开线圆柱齿轮传动结构优化的数学模型。基于智能算法(遗传算法)对齿数、模数、螺旋角等参数进行多目标优化,优化后齿轮的最小中心距减少了28.99%,有效的提高了空间利用率。同时该文研究结果可为智能设计、智能制造提供参考。To optimize the gear structure of a two-stage involute cylindrical gear reducer,based on the gear strength calculation standards and relevant theories of mechanical structure optimization design,the parameters that have a significant influence on gear contact strength and bending strength were analyzed.With the minimum center distance as the objective function,the gear strength and size as the constraint conditions,a mathematical model for the optimization two-stage involute cylindrical gear transmission structure was established.The paper conducts multi-objective optimization on parameters such as tooth number,modulus,and spiral angle based on genetic algorithm,the optimized minimum center distance of gear is reduced by 28.99%,and effectively improves the space utilization rate.Meanwhile,the research results can provide the basis for intelligent design and intelligent manufacturing.
