摘　　要：四辊轧机工作辊轴承及支承辊止推轴承失效的主要原因是轴向力过大。辊系各轴线不平行引起辊子间有轴向相对运动的趋势 ,在轧制压力作用下该轴向相对运动趋势使辊子间产生轴向静摩擦力 ,这就是产生轴向力的主要原因。通过调整机架窗口衬板和轧辊轴承座衬板 ,保持辊系各轴线的平行度 ,可显著降低轴向力 。The axial overload is the main factor which causes work roll bearings and back up thrust bearings of four high mill invalid.Unparallel between axes of the roll system causes the tendency for rolls to have relative axial motion.This tendency can generate axial statical friction by the action of the rolling pressure, which is the main factor causing the axial load.By adjusting the slide plates in the window of the mill housings and the slide ptates of the roll bearing housings, the palallelism of the axes of the roll system can be kept with the result that the axial load can be strikingly reduced.The theoretical analysis and the experiments prove the above.
