渐开线斜齿轮跨球测量中,跨球直径可选多大?即:跨球直径在怎样的范围内才可以与两侧齿面同时正确切触?这个问题在以往的文献中或泛泛地给出一个粗略的范围;或是一个实际上并不正确的公式。总之,没有得到确切解决。本文给出斜齿变位(内、外)齿轮跨珠测量时,跨球直径与齿面切触点之间关系的公式;以及跨球直径的临界条件。
Involute helical gear measurement across the ball, the cross-ball diameter can be selected how much? That is: within the scope of the cross-ball diameter can both sides of the tooth surface simultaneously with the correct contact? This problem in the literature in the past or generally Out a rough range; or a formula that is not actually correct. In short, did not get the exact solution. In this paper, the formula of the relationship between the diameter of the translamina and the tangent contact of the tooth surface when the bevel gear is displaced (inside and outside) is obtained, and the critical condition of the transimmunity diameter is given.
