对于高速回转件,平衡是一重要问题。但如何正确地规定平衡技术条件,尚未被人们所普遍了解。多年来,我们受外单位的委托,做了一些平衡检验工作。在工作中,我们发现,委托单位所提出的平衡技术条件,往往比较含糊,也有不少单位提出过高的精度要求。因此,作者在本 For high-speed rotary parts, the balance is an important issue. However, how to correctly stipulate the balance of technical conditions has not been widely understood by people. Over the years, we entrusted by the external units, to do some balance testing. At work, we found that the balance of technical conditions proposed by the commissioning unit is often rather ambiguous, and many units have put forward excessive precision requirements. Therefore, the author in this
