AMERICAN NATIONAL STANDARD Mechanical vibration - Rotor balancing - Part 12: Procedures and tolerances for rotors with flexible behaviour (a nationally adopted international standard) 美国国家标准机械振动.转子平衡.第12部分:挠性转子的程序和公差(国家采用的国际标准)
该国家采用的国际标准根据转子的特性和平衡要求,给出了具有灵活行为的转子的典型配置,描述了平衡程序,规定了最终平衡状态的评估方法,并建立了平衡质量标准指南。也可以作为更深入调查的基础,例如,当需要更准确地确定所需的天平质量时。如果适当注意指定的制造方法和平衡公差,则可以预期令人满意的运行条件。其目的不是作为任何转子的验收规范,而是说明如何避免严重缺陷和不必要的限制性要求。 结构共振及其修改不在本文件范围内。给出的方法和标准是通用工业机械经验的结果。它们可能不直接适用于专用设备或特殊情况。因此,在某些情况下,可能会偏离本文件。
This nationally adopted international standard presents typical configurations of rotors with flexible behaviour in accordance with their characteristics and balancing requirements, describes balancing procedures, specifies methods of assessment of the final state of balance, and establishes guidelines for balance quality criteria. Can also serve as a basis for more involved investigations, e.g. when a more exact determination of the required balance quality is necessary.If due regard is paid to the specified methods of manufacture and balance tolerances, satisfactory running conditions can be expected. Is not intended to serve as an acceptance specification for any rotor, but rather to give indications of how to avoid gross deficiencies and unnecessarily restrictive requirements. Structural resonances and modifications thereof lie outside the scope of this document.The methods and criteria given are the result of experience with general industrial machinery. It is possible that they are not directly applicable to specialized equipment or to special circumstances. Therefore, in some cases, deviations from this document are possible.
