摘要
针对某钢厂二十辊轧机用背衬轴承(双列圆柱滚子轴承)在使用中滚子端面与挡圈出现擦伤的情况,研究擦伤机理及原因,对挡边和滚子球基面进行改进,经使用证明:改进后能较好地减少滚子歪斜对轴承造成的损伤,提高了轴承的使用寿命。
Aiming at scratches in roller end face and retaining collar of backing bearings( double row cylindrical roller bearings) for 20- high roll mill in a steel plant,the mechanism and reason are studied about scratches. All ribs and spherical reference face of roller are improved. The practice proves that the damage of roller skewing to bearings is greatly reduced and the service life of bearings is improved after improvement.
