【摘要】 本文以宝钢 2 0 50热连轧机工作辊轴承座热变形故障为研究对象 ,详细分析了轴承系统的内热源 ,确认轴承内部的摩擦热是轴承升温的主要热源。本文提出一种通用的计算思路 :建立由工件→轧辊→轴承→轴承座的热传导模型 ,用有限元方法和三维有限元温度场程序 ,研究分析了轴承座的温度场分布规律。更多还原

【Abstract】 In this paper,the failure form of work roll bearing chock of 2050mm hot strip mill in bao steel is studied using Finite Element Method(FEM) the internal heat resources of bearing system is analyzed. The results show that the internal friction heat in the bearing is the major factor that inoluces temperature raise.A general calculatiog idea is presented. A pattern of heat conduction from strip to roll to bearing to bearing chock is esfablished. The rule of temperature distribution of bearing chock is discussed .更多还原
