摘　　要：对某悬臂离心风机用调心滚子轴承的失效进行了分析,认为由于电动机轴在运转过程中发热膨胀使联轴器两端面接触或停机时异物进入联轴器的两端面之间,使得电动机端调心滚子轴承无轴向游隙,出现偏载,最终导致过早失效,并提出了改进措施。The failure causes of self - aligning roller bearing are analyzed for a suspension arm mode centrifugal blower. The failure causes are considered as ： motor axles hot expand during operation and the foreign matter getting into terminal faces of the coupling when stop make the self - aligning roller bearing of motor have no axial clearance, which result in unbalance loading and early failure. And the improvement measures are put forward.
