【摘要】：以某1 580 mm热轧精轧工作辊推力轴承为例,通过分析PDA曲线初步推断推力轴承的失效是由异常轴向力造成。通过对轴向力来源进行分析,得出轧辊交叉是造成推力轴承失效的主要原因;进一步分析轧机平衡块和轴承座结构对轴承偏载的影响,提出轧机弯窜系统和轴承座的改造方案,并提出在推力轴承上增加隔圈以提高推力轴承的承载能力,防止滚动体被挤压变形。经验证,改进方案满足工程应用需求。
[Abstract]:Taking a 1 580mm hot rolling work roll thrust bearing as an example, the failure of the thrust bearing is preliminarily inferred by analyzing the PDA curve because of the abnormal axial force. Through the analysis of axial force source, it is concluded that roll crossing is the main reason for the failure of thrust bearing, and the influence of balance block and bearing seat structure on bearing bias load is further analyzed, and the transformation scheme of rolling mill bending and channeling system and bearing seat is put forward. The bearing capacity of thrust bearing is improved by adding spacer to the thrust bearing to prevent the rolling body from being extruded and deformed. It is proved that the improved scheme can meet the requirement of engineering application.
