摘　　要：给出了少齿数渐开线圆柱齿轮副节点外啮合的判定公式及具体的计算方法;对少齿数齿轮副节点外啮合时齿顶圆的有关问题进行了研究;通过分析少齿数齿轮副节点外啮合时的啮合特性,找出了符合实际的接触应力计算点,并推导出该计算点综合曲率的计算公式。The decision conditions and calculation method of the meshing beyond pitch point of involute gear pair with few teeth number are given. Some problems about addendum circle of the meshing beyond pitch point of involute gear pair with few teeth number were studied. Through analyzing the meshing characteristic, finds out the calculation point of contact strength of tooth surface and deduces the formula of synthetic curvature of this piont.
