正齿轮和斜齿轮的荷载能力计算.工业齿轮应用

[中文适用范围]： 本国际标准规定的公式旨在建立一种统一可接受的方法来计算直齿或斜齿工业齿轮的抗点蚀能力和抗弯强度能力。 本国际标准中的评级公式不适用于其他类型的轮齿劣化，例如塑性屈服、微点蚀、划伤、外壳破碎、焊接和磨损，并且不适用于可能出现不可预测的齿形损坏的振动条件。 弯曲强度公式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、轮缘的失效或齿轮毛坯通过腹板和轮毂的失效。 本国际标准不适用于锻造或烧结加工的齿。 它不适用于接触不良的齿轮。 该国际标准提供了一种可以比较不同齿轮设计的方法。 这不是有意的。 确保组装的驱动齿轮系统的性能。 它也不适合一般工程公众使用。 相反，它是供经验丰富的齿轮设计师使用的，他们能够根据类似设计的知识和对所讨论项目的影响的认识，为这些公式中的因素选择合理的值。 注意——请用户注意，本国际标准的计算结果应通过经验来确认。 [外文原描述]： The formulae specified in this International Standard are intended to establish a uniformly acceptable method for calculating the pitting resistance and bending strength capacity of industrial gears with spur or helical teeth. The rating formulae in this International Standard are not applicable to other types of gear tooth deterioration such as plastic yielding, micropitting, scuffing, case crushing, welding and wear, and are not applicable under vibratory conditions where there may be an unpredictable profile breakdown. The bending strength formulae are applicable to fractures at the tooth fillet, but are not applicable to fractures on the tooth working profile surfaces, failure of the gear rim, or failures of the gear blank through web and hub. This International Standard does not apply to teeth finished by forging or sintering. It is not applicable to gears which have a poor contact pattern. This International Standard provides a method by which different gear designs can be compared. It is not intended to assure the performance of assembled drive gear systems. Neither is it intended for use by the general engineering public. Instead, it is intended for use by the experienced gear designer who is capable of selecting reasonable values for the factors in these formulae based on knowledge of similar designs and awareness of the effects of the items discussed. CAUTION — The user is cautioned that the calculated results of this International Standard should be confirmed by experience.
