Scope

GB/T 3480的本部分规定了外啮合与内啮合渐开线圆柱齿轮的齿面承载能力的基本计算公式，包含了齿面接触疲劳强度评估中所有影响系数的计算式。本部分内容主要适用于油润滑传动装置；但只要啮合过程中始终存在足量的润滑剂，也可近似地用于（低速运转时）脂润滑传动装置。本部分给出的公式，适用于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（计算齿轮）的端面重合度εαn小于2.5并与其他基本齿条共轭的齿廓。采用本部分公式计算的结果与其他方法（见参考文献、、、）非常一致。除了第4章所述的损伤类型外，本部分不能直接用于评估其他的齿面损伤类型，如塑性屈服、刮擦或胶合。通过许用接触应力确定的承载能力称为“齿面承载能力”或“齿面接触强度”。如果本范围不适用，参考ISO 63361:2019的第4章。
