摘要
为了准确地确定齿轮修形参数,在分析传递误差对齿轮振动影响的基础之上,依靠有限元模型模拟了一对修形齿轮的啮合过程,并引入遗传算法,以减小齿轮的传递误差的波动为目标,对齿轮的修形参数进行了高精度的优化设计.研究表明,该方法确定的齿轮修形参数精确、有效,能够避免啮合冲击,并且能大幅度减小齿轮的动态传递误差波动,为无声齿轮的研究指出了新的设计方法.
To determine the parameters of gear profile modification accurately,the effect of transmission error on gear vibration was analyzed to simulate the meshing process of a pair of gears via FEM.With the GA（genetic algorithm）introduced into the process to reduce the fluctuation of transmission error,the profile modification parameters of spur gears were designed optimally and accurately.The results showed that the gear profile modification parameters thus given are so accurate and efficient that the impact on gear meshing can be avoided with the dynamic fluctuation of transmission error of spur gears decreased greatly.A new way to the RD and design of noiseless gears is thus proposed.
