三、空间交错轴齿轮齿廓论 (1) 啮合条件的表现可以称之为圆柱直齿轮齿廓理论宪法的第一条是:“接触点上两齿廓的公法线必通过其节点”。对于斜齿轮,只要是在端截面(与轴垂直面)内讨论,上述论点亦然通用。不过,如果变为讨论齿面法线,上述观点就不能通用。有必要以瞬间轴或是节线代替节点。仅是斜齿轮就有了上述考虑的必要,所以作为空间齿轮传动的交错轴传动,如何表现它的啮合条件就是一个有必要深入考虑的问题。正如处理平面曲线时用切线座标和切线极座标甚为有利一样,选定什么座标对于空间交错齿轮也极为重要。笔者根据前田和松山
Third, the spatially staggered shaft gear profile (1) the performance of meshing conditions can be called cylindrical spur gear tooth profile The first of the constitution is: “The contact point of two tooth profile of the common normal will pass through its node.” For helical gears, the same argument applies as long as it is discussed in the end section (perpendicular to the axis). However, this view can not be generalized if it becomes a discussion of tooth surface normals. It is necessary to replace nodes with momentary axes or pitch lines. Just bevel gears have the above considerations necessary, so as a spatial gear drive staggered shaft drive, how to show its meshing conditions is an issue that needs further consideration. Just as it is advantageous to use the tangent and tangent polar coordinates when dealing with planar curves, choosing which coordinates are also important for spatially staggered gears.
