| 摘 要： | 由于对旋轴流式风机电动机轴承要承受大的轴向负荷和径向负荷，实际使用过程中常发生电动机轴承损坏的现象。这里针对此问题，通过对比对旋风机电动机输出轴安装叶轮前后的受力情况，对电动机轴承进行受力分析，查明电动机轴承损坏的机理。并在对电动机轴承组进行结构分析的基础上，给出两种有效的轴承组结构。

| Abstract: | Due to the strong axial and radial load to the bearing of electromotor in counter- rotating axial fan, it is always occurred that the bearing was damaged in use. This paper aims to investigate the reason of the damage through comparing the stress the output axis endured after installing impeller and the situation before to analyze the intensity of bearing in electromotor. Two types of effective structure of bearings were given based on the structure analysis of the bearing. |
