摘　　要：为分析某热轧厂R2轧机传动轴断裂的原因,对该轧机在典型工况下传动轴受力状况进行了现场试验研究,采用现代设计方法对传动轴进行分析,结果表明,平衡力产生的弯矩造成轴的应力集中而导致断裂。根据此结果对轴的结构进行了改进。To determine the reasons of failure of the driving shaft of the R2 rougher mill in a certain hot-strip plant, force status of the rolling mill under typical work conditions is studied by field test and the failure reason is analyzed by modern mechanical design method. The results indicate that the flexural torque produced by the balance force of the rolling mill leads to stress concentration, which further results in the shaft failure. According to the analysis, the improvement of the driving shaft is proposed.
