大型磨机齿轮箱常见故障振动的频域特征与故障诊断

Frequency-domain Characterization of Common Fault Vibration of Heavy Mill Gearbox and Fault Diagnosis

大型磨机齿轮减速箱是粉磨生产过程的重要设备。文中重点讨论其常见的齿轮磨损和滚动轴承疲劳剥落、点蚀等故障振动的频域特征及诊断,并用实例加以说明。

The reduction gearbox of heavy mill is key to powder milling. The paper illustrates the frequencydomain characteristics of fault vibration caused by frequent gear abrasion, the fatigue spalling of rolling bearing and pitting corrosion, based on which it discusses the diagnosis of the faults.
