我厂一台 Z3025型摇臂钻床,72年购进后就发现主轴漏油。机床启动后,油飞溅到操作者身上,只好做一只铁皮圆筒,罩在主轴套简上.但油沿筒壁溅出,影响工件划线。后对主轴箱进行拆检,发现主要原因是花键套筒轴承座的凸台高度不够,而回油孔又景不及回油所引起的(图1)。针对这种情况,我们采取了如下的措施:(1)将原主轴花键套筒轴承座2的凸台车去,镶一个比原来高20mm 的凸台:凸台的结合端面涂防漏胶:(2)将原主轴花键套筒1的内花键车去20mm,
I plant a Z3025-type radial drilling machine, 72 years after the purchase found spindle spills. After the machine is started, the oil splashes to the operator, but has to make a metal cylinder, which covers the spindle sleeve, but the oil splashes along the cylinder wall, affecting the work line. After the demolition of the spindle box inspection and found that the main reason is that the boss of the spline sleeve bearing height is not enough, and back to the oil hole and the King missed the oil caused by the (Figure 1). In view of this situation, we have taken the following measures: (1) the original spindle spline sleeve bearing bushing car 2, insert a boss 20mm higher than the original: : (2) the original spindle spline sleeve 1 to the internal spline car to 20mm,
