摘　　要：本文讨论了渐开线齿轮传动的啮合区域 ,提出了少齿数渐开线齿轮副节点外啮合时 ,齿面接触强度应以实际啮合线的中点作为计算点 ,并提出了节点外啮合的判定条件 ;推出了在实际啮合线中点啮合时综合曲率半径的计算公式 ;最后通过一个实例 。This paper discusses the engagement field of involute transmission, pointing out the judgment condition when little teeth number involute gear pair pitch point meshes externally. The counting point of gear surface contacted strength is the middle of the practical line. The point meshing comprehensive radius of curvature's counting formulas in the practical line of action is given and the error of both pitch point and the middle of the practical line is described.
