标准范围

本国际标准中规定的公式旨在建立统一可接受的主推进耐久性抗点蚀和抗弯强度计算方法船舶、近海船舶和钻机的辅助齿轮，具有直齿或螺旋齿，并且船级社的规则。本国际标准中的额定值公式不适用于其他类型的轮齿劣化，如如塑性屈服、微点蚀、擦伤、外壳破碎、焊接和磨损，不适用于振动可能存在不可预测的配置文件故障的情况。弯曲强度公式适用适用于齿圆角处的断裂，但不适用于齿工作轮廓表面上的断裂，齿轮轮辋，或齿轮毛坯通过腹板和轮毂的故障。本国际标准不适用于牙齿通过锻造或烧结完成。本标准不适用于接触模式不良的齿轮。该国际标准提供了一种比较不同齿轮设计的方法。这不是故意的确保装配驱动齿轮系统的性能。它不打算用于一般工程公众。相反，它旨在供有经验的齿轮设计师使用，他们能够选择合理的这些公式中的因子值基于对类似设计的了解和对讨论的项目。警告-提醒用户，本国际标准的计算结果应为经经验证实。

The formulae specified in this International Standard are intended for the establishment of a uniformly acceptablemethod for calculating the pitting resistance and bending strength capacity for the endurance of the mainpropulsionand auxiliary gears of ships, offshore vessels and drilling rigs, having straight or helical teeth and subjectto the rules of classification societies.The rating formulae in this International Standard are not applicable to other types of gear tooth deterioration, suchas plastic yielding, micropitting, scuffing, case crushing, welding and wear, and are not applicable under vibratoryconditions where there may be an unpredictable profile breakdown. The bending strength formulae are applicableto fractures at the tooth fillet, but are not applicable to fractures on the tooth working profile surfaces, failure of thegear rim, or failures of the gear blank through web and hub. This International Standard does not apply to teethfinished by forging or sintering. This standard is not applicable to gears having a poor contact pattern.This International Standard provides a method by which different gear designs can be compared. It is not intendedto assure the performance of assembled drive gear systems. It is not intended for use by the general engineeringpublic. Instead, it is intended for use by the experienced gear designer who is capable of selecting reasonablevalues for the factors in these formulae based on knowledge of similar designs and awareness of the effects of theitems discussed.WARNING — The user is cautioned that the calculated results of this International Standard should beconfirmed by experience.
