模型分析优化行星支架变形较大，最大应力 97.3MP。考虑增加刚度。平行轴 1理论上轴的直径可以减小到 100,但是轴承的动载能力要求内径达到 150.变形大 130um，增加轴承及轴刚度减少噪音。平行轴 1 轴承 1 对第二对齿轮副的响应频率最低 88Hz(5280rpm）,在工作范围之外。齿轮修形齿向齿廓修形后校核经过优化得到了比较经济的参数。轴承04000080000120000160000200000240000280000sun shaft Bearing 2sun shaft Bearing 1planetary2 Bearing 2planetary 3 Bearing 2planetary 3 Bearing 1planetary 2 Bearing 1planetary 1 Bearing 2planetary 1 Bearing 1pingxingzhou 2 bearing 2pingxingzhou 2 bearing 1pingxingzhou 1 bearing 4pingxingzhou 1 bearing 2pingxingzhou 1 bearing 1carrier Bearing 1Life (hrs)BearingsGearbox 1: Modified LifeISO 281Adjusted 齿轮0123456Wheel 2Wheel 1SunRing GearPlanet 3Planet 2Planet 1Pinion 2Pinion 1Safety FactorGearGearbox 1:Safety FactorsSafety Factor BendingSafety Factor Contact轴(仅定义两个轴）附：箱体
