我厂三台550轧机人字齿轮座轴伸端长期漏油(见图1)。漏油的主要原因是: 1.回油线路设计不佳。由图可见,回油由上轴承腔径上中盖孔(φ15毫米)回到中轴上,再经下中盖孔(φ25毫米)回到下轴上,最后经箱体底座的总回油孔(φ35毫米)回到油池。这种回油线路有大量的油直接流在轴上,轴端虽然设有档油环,但也常因轧制冲击力,油环不能定位,大量的油流到油环外侧,沿转轴向外泄漏。

My factory three 550 rolling mill herringbone seat shaft extended long-term oil leakage (see Figure 1). The main reason for the oil spill is: 1. The oil return line is poorly designed. It can be seen from the figure that the oil is returned to the central shaft through the upper cover hole (φ15 mm) on the bore of the upper bearing and then returned to the lower shaft through the lower middle cover hole (φ25 mm). Finally, Hole (φ35 mm) back to the sump. This oil return line has a lot of oil directly on the shaft, although the shaft end with a gear ring, but also often due to rolling impact, oil ring can not be positioned, a large amount of oil flow to the outside of the oil ring along the shaft Leak outside.
