1450热精轧机万向接轴断裂研究

Research on Breakage of Rolling Mill Universal Coupling

根据部分实测数据 ,从力学分析、扭振测试分析、断口检验等方面对 1 45 0热精轧机万向接轴断裂原因进行分析 ,得出导致万向接轴断裂的主要原因是系统设计、材质和扭振 ,针对断裂原因提出避免断裂的措施 ,对保护轧机主传动系统 ,减少事故发生 。

Based on part of the measured data, the breakage from the influence of mechanics and torsional vibration,and by the break inspection and fracture evaluation is analysised . The result shows that system design, torsional vibration and material are the main reasons for the breakage, it is important theoretic sense and high engineering practical value for reducing accident, the result offer a practical reference to the study else rolling mill.
