本文概述了南京航空学院与南京钢铁厂共同开发的轧钢机系列轴承在线故障诊断技术所取得的突破性进展。详细地叙述了轧钢机轴承在线监测和诊断的方法。从现场监测的结果,作者提出了同一个滚动轴承内多个同类故障的诊断方法。 This article outlines the breakthroughs made in online fault diagnosis of rolling mill bearings developed jointly by Nanjing Aeronautical Institute and Nanjing Steel Works. Described in detail the rolling mill bearing on-line monitoring and diagnosis methods. From the results of on-site monitoring, the authors propose a number of similar fault diagnosis methods within the same rolling bearing.
