本标准提供的计算方法仅适用于校核锥齿轮轮齿过渡曲线部分抗疲劳断裂的能力,对于轮齿其它部位、其它形式的断裂,包括因剧烈冲击振动或过渡点蚀以及由于其它机械损伤引起应力集中,或因磨削烧伤、冶金热处理等工艺缺陷引起的齿轮断裂不能使用本标准。 This standard provides calculation method is only applicable to check the bevel gear tooth transition curve part of the anti-fatigue fracture capacity, for other parts of the gear, other forms of fracture, including due to severe impact vibration or transition pitting and due to other mechanical damage Stress concentration, or because of grinding burns, metallurgical heat treatment process defects caused by gear failure can not use this standard.
