摘　　要：针对邯钢中板线2800mm轧机支承辊油膜轴承运行不稳定,多次出现漏油、进水、密封损坏、轴承巴士合金严重脱落等问题进行原因分析,通过对锁紧螺母背紧量尺寸和联接梁尺寸的修正,解决了轴承在轧辊上的准确定位问题,通过DF油封材质和结构的改进和密封压盖的改进,改善了密封状况,达到了油膜轴承长周期稳定运行的目的。Aiming at the problems of the oil film bearing of the 2 800 mm medium-plate mill backing roll in Handan Steel,such as instability in operation,oil leakage,water penetration,seals failure and the Babbitt bearing drop-out,this article analyzed the reasons.By correcting of the preloading amount of locknut and the dimension of connection beam,the accurate location of the bearing in the roll was enhanced.The seal status was improved by ameliorating the material and constructer of the DF oil-seal and the gland,making the oil film bearing have a longer and steady action cycle.
