高速线材轧机由于转速较高,其机械传动系统易出现突发故障。由于该类齿轮箱的结构特点及故障类型的差异性,采用时域分析和频谱分析的适应性有所差异。通过实测数据的分析表明,轴承类故障对于高阶的时域分析指标异常敏感,而在常见的齿轮箱故障中,转轴类零部件故障的识别和判断难度相对较高。 High-speed wire rod mill due to high speed, the mechanical transmission system prone to sudden failure. Due to the structural characteristics of the gearbox and the type of fault, the adaptability of time-domain analysis and spectrum analysis are different. The analysis of measured data shows that bearing fault is sensitive to high-order time-domain analysis. However, in the common gearbox fault, it is more difficult to identify and judge the failure of the spindles.
