摘　　要：保证弹性支承下弧齿锥齿轮具有良好的接触特性是新型航空发动机动力传输系统设计的关键技术之一。针对某航空发动机转子系统中的弧齿锥齿轮,以齿轮副在刚性支承下的接触区中心点和传动误差值作为预期的目标值,建立了弧齿锥齿轮的多目标优化模型,结合线性加权与轮流坐标搜索法,对弧齿锥齿轮切齿加工参数进行了优化设计,使设计后的齿轮在弹性支承下具有良好的接触特性。实现了对弹性支承下弧齿锥齿轮接触印痕与传动误差的预控。The key technology in designing a new aero-engine drive system is to ensure that spiral bevel gears with elastic supports have the best contact characteristics.The contact pattern center point and transmission error magnitude of spiral bevel gears with rigidity supports are optimization objectives.For a pair of spiral bevel gears in aeroengine,a multi-objective optimization mathematical model of spiral bevel gears is established,and machine-tool settings are optimized with linear weighted sum method and coordinate rotation search method,which ensured that the designed spiral bevel gears with elastic supports have the best contact characteristics.Control of the bearing contact and transmission error is realized before the design of spiral bevel gears with elastic supports.
