标准摘要
[中文适用范围]： 该文件建立了与单个圆柱渐开线齿轮和扇形齿轮的双齿面径向复合偏差相关的轮齿分类系统。 它规定了轮齿偏差的适当定义、轮齿面分类系统的结构以及轮齿偏差的允许值。 它提供了计算各个产品齿轮与主齿轮双齿面接触配合时的公差的公式。 不包括公差表。 本文件适用于参考直径不超过 600 毫米的三齿或三齿以上齿轮。 本文件不提供齿轮设计指南，也不建议公差。 [外文原描述]： This document establishes a gear tooth classification system relevant to double flank radial composite deviations of individual cylindrical involute gears and sector gears. It specifies the appropriate definitions of gear tooth deviations, the structure of the gear tooth flank classification system, and the allowable values of the gear tooth deviations. It provides formulae to calculate tolerances for individual product gears when mated in double flank contact with a master gear. Tolerance tables are not included. This document is applicable to gears with three or more teeth that have reference diameters of up to 600 mm. This document does not provide guidance on gear design nor does it recommend tolerances.
