Scope

GB/T 3480 的本部分规定了具有一定轮缘厚度（外齿SR＞0.5 ht和内齿SR＞1.75 mn）的渐开线圆柱内、外直齿轮和斜齿轮的弯曲应力计算的基本公式。本部分考虑了所有由齿轮传递的载荷所引起的、能够定量评估的影响齿根应力的因素。在实际中，内齿轮可能会产生不同于齿轮弯曲疲劳的失效形式，如裂纹从齿根圆开始沿径向向外扩展。本部分的计算结果不能确保对非弯曲疲劳失效形式具有足够的安全性评估。
本部分包括了Hirt[11]、Strasser[14]和Brossmann[10]等人所进行的试验测试和理论研究内容。计算结果与其他方法一致（参考文献[5]、[6]、[7]和[12]）。本部分给出的公式适用于符合 GB/T 1356中由基本齿条型刀具加工的圆柱齿轮齿廓，也可用于当量齿轮端面重合度εαn小于2.5并可与其他基本齿条共轭的齿廓。
根据许用弯曲应力得出的承载能力称为“轮齿弯曲强度”。该强度的这种计算方法与其他类似的方法结果一致，这一点在 ISO 63361 中的“范围”中已有说明。
如果本部分不适用，参考 ISO 63361:2019的第4章。
