磨床砂轮、皮带轮等回转件的不平衡所引起的振动,是导致被磨表面产生波纹和光洁度下降的主要原因之一.为了提高磨削质量,必须对砂轮等进行精密平衡.传统的平衡架上平衡砂轮方法,平衡精度不高,劳动量大.对电动机皮带轮目前尚缺乏行之有效的现场平衡方法,当使用时间较长或大修后,不易达到较高的平衡要 The vibration caused by the imbalance of the grinding wheel, pulley and other rotating parts is one of the main causes of the ripples and smoothness of the surface being abraded. In order to improve the grinding quality, the grinding wheel and the like must be precisely balanced. Balance wheel method, the balance accuracy is not high, a large amount of labor.On the motor belt pulley is still a lack of effective on-site balance method, when the use of a long time or overhaul, it is difficult to achieve a high balance
