摘　　要：采用参数化建模方法建立了风力发电机增速齿轮箱中行星斜齿轮及其行星架的精确三维模型,应用非线性动力学理论及数值计算方法分析了该行星齿轮的齿面接触应力随时间的变化规律,得到了轮齿变形和相应的接触应力以及行星齿轮内外啮合的时变刚度曲线,同时分析了行星架的冲击应力,为该类行星齿轮结构的优化设计和分析提供了理论依据。Precise 3D models of helical planetary gear and its carrier in the wind turbine gearbox are set up based on the parametric modeling method. The contact stress curves of planetary gear are ana- lyzed by the nonlinear dynamics theory and numerical calculating method, and the deformation and contact stress of the gear teeth are got, the time-varying mesh stiffness curve of planetary gear meshing inside and outside is acquired at the same time, the impact stress of the carrier is also analyzed. The re- searching results provide a theoretical basis for the structure analysis and optimization of the type of planetary gear.
