沈阳中捷人民友谊厂生产的摇臂钻床,为了防止主轴漏油,在回转轴上加了挡油盖和挡油墙,但仍有油从回转轴甩出,甩出的油呈雾状,如在回转轴旁放张白纸,不久纸就变了颜色,甩上了一层油。这油是怎么漏出来的呢?他们由表及里反复观察多次试验终于发现,挡油盖与挡油墙之间的间隙过小,产生毛细现象,使油反爬过挡油墙漏出。放大了间隙,就防止了漏油。 Shenyang Zhongjie People’s Friendship Factory radial rocker drilling machine, in order to prevent the main shaft oil leakage, the oil tank on the rotary shaft and the oil retaining wall, but there is still oil thrown from the rotary shaft, the oil thrown mist, If you put a piece of white paper next to the rotating shaft, the paper will soon change its color and you will be thrown to a layer of oil. This oil is how it leak out? They repeatedly observed from the table and in many tests finally found that the gap between the oil cover and the oil retaining wall is too small, resulting in capillary phenomenon, so that the oil crawl across the block wall leakage. Enlarge the gap, to prevent the oil spill.
