摘　　要：提出一种针对小交错角面铣准双曲面齿轮的几何设计方法,推导了基于单叶双曲面副瞬时轴线的空间节圆锥副设计参数几何关系,提出了考虑齿根平滑过渡的小交错角准双曲面齿轮副啮合特性控制方法。建立了齿轮副啮合模型与有限元分析模型,研究了不同外载荷对齿面啮合特性的影响。小交错角齿轮传动原理样机验证了准双曲面齿轮可在小交错角极端几何尺度下平稳工作。A design methodology for hypoid gears in low crossed shaft angle was proposed.The geometric relationships of pitch cones were derived based on the instantaneous axis of uniparted hyperboloid.Considering the root part smoothness,the mesh behavior controlling methodology of hypoid gears with low crossed shaft angle was proposed.The finite element analysis was performed to investigate the influences of different loads on the mesh behavior.The prototype of hypoid gears proposed may work in low crossed shaft angle stably.
