【摘要】 本文根据斜齿圆柱齿轮齿廓曲面的数学方程，运用微分几何学中的两类基本量，分析了斜齿轮齿廓曲面在一点邻近的形状，从而证明了相错轴斜齿轮传动的两轮齿为点啮合。更多还原

【Abstract】 On the basis of mathematic equations of helical gear tcoth surface ,the appoaranee in the neighbour-hood of a point on the gear tcoth surface is analysized , and the point contact bewteen helical gears with stag-gered axes is proved with two kinds of basic parameters in differential geometry.更多还原
