摘　　要：该文针对某钢铁公司棒材生产线中轧机减速器的轴承失效问题,从应力数据和工作环境进行分析,得出其失效的原因。重点从轴承的选型、游隙的调整、润滑、减速器伞箱的轴承压盖改进、运行与监测等方面,提出预防轧机减速器中滚动轴承过早失效的改进措施,进而消除了减速器滚动轴承失效的隐患。改造后的生产运行结果表明,改进后的轴承使用寿命明显增加,使减速器的正常工作时间大大提高,达到降本增效的目的。Based on the analysis of stress data and working environment,the reason of bearing failure of rolling mill reducer in bar production line of an iron and Steel Company is obtained.From the aspects of bearing type selection,clearance adjustment,lubrication,improvement of bearing gland of gearbox,operation and monitoring,the improvement measures to prevent premature failure of rolling bearing in rolling mill reducer are put forward,thereby the hidden trouble of the failure of the rolling bearing of the reducer is eliminated.The operation results show that the service life of the improved bearing is obviously increased,and the normal working time of the reducer is greatly increased.
