煤矿机械,由于工作环境的限制,不仅具备良好的防尘装置还必须严禁有渗漏油的现象,为此对于密封的要求是相当高的。一、存在的问题17型刮板输送机上的减速器是一个三级展开式的减速器,过去经常出现渗漏油的地方有五处:箱体的合口面处;第一轴的轴承盖及高速旋转的轴头处;其余则发生在中、低速旋转轴的密封处。图1以 ABCDE 表示漏油的地方。 Coal mining machinery, due to the limitations of the working environment, not only have a good dust-proof device must also be strictly prohibited the phenomenon of leakage of oil, for which the requirements of the seal is quite high. First, the existing problems 17-type scraper conveyor reducer is a three-stage explosion-proof reducer, the past often leak oil where there are five: the mouth of the box at the mouth; the first axis of the bearing cap and High-speed rotation of the shaft at the head; the rest occurred in the low-speed rotating shaft seal. Figure 1 ABCDE said oil spill place.
