摘　　要：分别计算了齿轮副的啮合点在节点左右两侧的瞬时啮合效率,按啮合线长度进行积分,得到齿轮副在啮入至啮出过程的平均传动效率表达式,该表达式的自变量包括主动轮齿数z1、传动比i、摩擦因数f以及压力角α。分别针对单级圆柱直齿轮传动和二级圆锥-圆柱齿轮传动的参数进行优化设计,以啮合过程平均效率最大为目标函数,采用惩罚函数外点法计算,参照优化结果设计并制造了一台二级圆锥-圆柱减速器,在不同试验项目下进行检验,其传动效率不低于94%,验证了参数优化设计的正确性。The instantaneous meshing efficiency on both sides of the nodes of the gear is calculated respectively.The integral along the length of thread engagement is calculated for the average transmission efficiency expression of gear in meshing process.The expression of the independent variables including active tooth number z1,the transmission ratio i,the friction coefficient f and pressure angleα.The optimized design for the gear parameters of single stage cylindrical gear and two stages cone-cylindrical is carried out respectively.Taking the average efficiency to be the maximum as optimizing object,the penalty function calculation method is adopted.Considering the optimization results,a two stage cone-cylindrical reducer is built and its efficiency is above 94%.The correctness of the parameter optimization design is verified.
