摘　　要：采煤机截割部末级行星机构的支承轴承游隙影响浮动油封的工作可靠性,通过ANSYS软件分析得到了采煤机截割部双列圆锥滚子轴承内外圈相对位移与游隙的关系,并以此为基础进一步分析了游隙对浮动油封密封间隙的影响,得到量化结果,为采煤机截割部中双列圆锥滚子轴承游隙的选择提供了参考依据。The bearing clearance of the last stage planetary mechanism of the shearer cutting part affects the working reliability of the floating oil seal.Through the analysis of ANSYS software,the relationship between the relative displacement of the inner and outer rings of the double row tapered roller bearing in the shearer cutting part and the clearance was obtained.Based on this,the influence of the clearance on the sealing clearance of the floating oil seal was further analyzed,and the quantitative results were obtained.It provided a reference basis for the selection of clearance of double row tapered roller bearing in the cutting part of shearer.
