重要用途的高应力齿轮,通常在其齿根部位制成挖根大圆弧的形式。这种挖根大圆弧齿轮仅在渐开线齿形部分进行磨削,而不磨削的挖根圆弧部分保留其在切齿时所得到的几何尺寸。带凸头的非标准复杂基准齿形和挖根大圆弧齿轮的尺寸是一致的。在设计用于已知齿数和变位系数的齿轮的带凸头非标准复杂基准齿形的刀具时,应遵循以下两个准则:一是工作齿形保证不发生根切和考虑到磨削余量的几何工艺;二是保证加工得到的齿形根部弯曲应力最小,即轮齿具有较高的弯曲强度。这时,对于已知齿数和变位系
High-stress gear for important applications, usually in the form of a large root arc at its root. This digging large arc gear only in the involute toothed part of the grinding, and not digging arc root part retains the geometry obtained when the tooth. The non-standard complex datum with lugs is the same size as the dug arc gear. The following two guidelines should be followed in the design of a tool with a non-standard complex datum toothed gear for a gear of known number of teeth and coefficients of displacement. The first is to ensure that the work tooth does not undercut and allow for grinding The amount of geometric technology; the second is to ensure that the processed tooth root bending stress is minimal, that is, tooth gear has a higher bending strength. At this time, for the known number of teeth and displacement system
