我厂C6163车床床头箱Ⅰ轴与法兰盘之间经常漏油,一直未能得到很好的解决。经分析,油是从Ⅰ轴及其分油环的配合间隙流出的。正常情况下,油应从床头箱上的法兰盘回油内槽通过回油孔流入床头箱,而当轴与分油环配合间隙过大时,产生大量回油,内槽不能满足大油量的流动。加之回油孔过小,使部分油不能及时回流到床头箱内,而是顺着法兰盘上的回油槽向外渗漏,使油料大量浪费。车床三角皮带因受机油长时间的浸泡而腐蚀老化,更换频繁,增加了维修成本。
I plant C6163 lathe headstock flange often leaked between the first axis, has not been able to get a good solution. After analysis, oil is from the Ⅰ axis and its oil ring with the gap outflow. Under normal circumstances, the oil should flow from the flange on the headstock tank back to the headstock through the oil return hole, and when the shaft and the oil ring with the gap is too large, a lot of back to the oil, the tank can not meet the large Flow of oil. Coupled with the oil return hole is too small, so that some of the oil can not be timely back to the bedside box, but along the flange back to the tank leakage to the outside, so that a lot of waste oil. Lathe V-belt due to prolonged immersion oil corrosion and aging, frequent replacement, an increase of maintenance costs.
