摘　　要：针对某引风机电机轴承外环与轴承座内孔之间存在较大紧力,导致减振器无法正常工作的故障,分析了故障的特点和原因,采取措施后消除了振动。In view of the fault that the vibration damper of a draft fan motor can not work normally due to too tight pressing force existing between the outer ring of its bearing and the inner bore of its bearing seat,causes leading to the problem are analyzed.The vibration is finally eliminated after some countermeasures are taken.
