在机械产品中应用螺旋付提升机构是很普遍的,有许多磨床产品中也利用螺旋付作为快速提升磨头的装置,但在这种装置中往往会出现较大的噪声,如3724平面磨床和3756立轴圆台平面磨床等产品,常在快速机动升降磨头时出现所谓的“黄牛叫”现象,遇到这个问题时感到非常棘手,因为它大大超过了标准所规定 The use of helical pay hoists in mechanical products is common, and many grinder products also utilize helical pay as a means of rapidly lifting the grinder, but large noise tends to occur in such devices as the 3724 surface grinder and 3756 vertical axis circular table grinding machine and other products, often in the fast maneuver lift head when the so-called “cattle called” phenomenon, encountered this problem is very tricky, because it greatly exceeded the standard
