【摘要】 为提升非正交偏置变位斜齿面齿轮传动啮合性能以满足航空动力传动的使用要求，提出了非正交偏置变位斜齿面齿轮副主动小轮齿面修形设计方法，选取主动小轮齿向、齿廓修形曲线的8个几何控制参数作为优化变量，以减小承载传动误差波动幅值、降低齿面接触闪温、均匀齿面载荷分布为优化目标，建立多目标优化模型，并采用多目标遗传算法NSGA-Ⅱ实现优化求解。算例分析表明：优化齿面修形可使承载传动误差波动幅值显著下降、大轮齿顶部位的最大齿面接触闪温明显减小、齿面载荷分布趋于均匀，为空间紧凑高性能航空动力传动系统的设计提供了理论参考。更多还原

【Abstract】 To enhance the meshing performance of a non-orthogonally offset profile-shifted helical face gear drive to meet the requirements of aviation power transmission, a tooth-surface modification design method for the driving pinion was proposed. Eight geometric control parameters of the tooth direction and tooth profile modification curve of the driving pinion were selected as optimization variables, a multi-objective optimization model was established to reduce the amplitude of load transmission error fluctuations, lower the contact flash temperature of tooth surfaces and achieve uniform load distribution on tooth surfaces. The NSGA-Ⅱ multi-objective genetic algorithm was employed to solve the optimization problem. Case-study results indicate that the optimized tooth-surface modification significantly decreases the fluctuation amplitude of the loaded transmission error, markedly reduces the maximum tooth contact flash temperature at the tooth tip of the helical face gear, and yields a more uniform load distribution on the tooth surface, which provides a theoretical reference for the design of compact and high-performance aero-power transmission system.更多还原
