在现代工业中,为了减少转动机械的振动、提高工作转速、延长工件使用寿命,必需消除旋转工件的动不平衡。为了实现这一目的,通常采用动平衡机对旋转工件(通常称为转子)作动平衡校验。由于需要作动平衡检验的旋转工件的品种、形状、重量、支承形式等差异极大,而且动平衡的精度要求也各不相同。因此,在对旋转工件作动平衡检验时必需根据转子的特点,选用合适的动 In modern industry, in order to reduce the vibration of rotating machinery, increase the working speed and prolong the service life of the workpiece, it is necessary to eliminate the dynamic imbalance of the rotating workpiece. For this purpose, a balancing machine is usually used to balance the rotating workpiece (often referred to as a rotor) with a balancing machine. Due to the need to check the balance of the rotation of the workpiece varieties, shapes, weights, forms of support and other great differences, and balancing accuracy requirements vary. Therefore, the balance of the workpiece rotation test must be based on the characteristics of the rotor, select the appropriate action
