23 5 0铝箔轧机工作辊止推轴承频繁发生短寿烧损事故 ,轧机被迫降速运行 ,严重困扰着企业生产。采用全新直接测量轴向力方案 ,对 2 3 5 0铝箔轧机工作辊轴向力大小、作用方向及其周向分布进行全面测量 ,并对测试结果和轴承短寿问题进行分析 ,指出轴向力产生原因及其组成部分 ,轴承短寿烧损的主要原因在于轴向力严重偏载和超载。本测试为研究 2 3 5 0铝箔轧机止推轴承延寿治烧问题提供重要实践依据 23 5 0 Aluminum foil rolling mill work roll thrust bearing frequent short-lived burning accident, the mill was forced to run at a speed, seriously troubling the production of enterprises. A new direct measurement of axial force scheme was used to measure the axial force, the action direction and the circumferential distribution of work roll of 2350 aluminum foil mill comprehensively. The test results and bearing short life were analyzed. It was pointed out that the axial force The reason and its components, the main reason for bearing short-lived burning is the partial axial load and overload. This test provides an important practical basis for the study of extending the life of 2330 aluminum foil rolling mill thrust bearing
