标准摘要
[中文适用范围]： 本文件规定了平衡具有刚性行为的转子的程序和不平衡公差。 它规定了a）允许残余不平衡的大小，b）校正平面的必要数量，c）允许残余不平衡到公差平面的分配，以及d）如何考虑平衡过程中的误差。 注：在 ISO 21940-14 中，详细考虑了平衡误差的评估。 ISO 19499 包含转子平衡的基础知识，其中介绍了平衡。 本文件不涵盖具有柔性行为的转子的平衡。 ISO 21940-12 中规定了具有灵活行为的转子的程序和公差。 [外文原描述]： ISO 21940-11:2016 establishes procedures and unbalance tolerances for balancing rotors with rigid behaviour. It specifies a) the magnitude of the permissible residual unbalance, b) the necessary number of correction planes, c) the allocation of the permissible residual unbalance to the tolerance planes, and d) how to account for errors in the balancing process. NOTE In ISO 21940‑14, the assessment of balancing errors is considered in detail. Fundamentals of rotor balancing are contained in ISO 19499 which gives an introduction to balancing. ISO 21940-11:2016 does not cover the balancing of rotors with flexible behaviour. Procedures and tolerances for rotors with flexible behaviour are dealt with in ISO 21940‑12.
