目前,在一些矿山仍存在提升机减速器漏油问题,不仅浪费大量的润滑油,而且污染环境,不利于文明生产,有待引起足够重视。 苏州阳西矿使用的一台XKT2×2×1B型矿井提升机(1972年产品),就长期存在轴瓦渗、漏油问题,其中高速轴尤为严重。据作解体分析,认为引起漏油的主要原因如下: (1)各轴承处没有回油槽(孔),致使润滑油无通路至油箱,只得从迷宫式端盖处向外渗漏; (2)由于上、下轴瓦剖分面存在间隙,润滑油除从端盖渗出外,还从剖分面沿联接螺栓向外流出; (3)减速器箱盖与箱座接合面加工粗糙,虽经螺栓联接仍有缝隙,润滑油可沿缝隙渗漏溢出。 At present, in some mines, there is still the problem of oil leaking of hoist reducer, which not only wastes a lot of lubricating oil, but also pollutes the environment and is not conducive to civilized production, awaiting sufficient attention. A XKT2 × 2 × 1B mine shaft hoist (1972 product) used by Yangxi Mine in Suzhou City has a long-term problem of shaft infiltration and oil leakage, in which the high-speed shaft is especially serious. According to the disintegration analysis, the main reasons causing oil leakage are as follows: (1) there is no oil return groove (hole) at each bearing, resulting in no oil passage to the oil tank and only leakage from the labyrinth end cap; (2) Due to the existence of the gap between the upper and lower bearing surface, lubricating oil in addition to exuding from the end cover, but also out from the split along the coupling bolt outward; (3) gear box cover and the box joint rough surface processing, though There are still gaps in the bolt connection, lubricating oil can leak through the gap.
