通过对轴承振动信号的测试和分析 ,可以较准确地判断轴承损伤类故障。根据此原理 ,研制了THZJ1铁路货车轴承故障诊断机 ,它可自动连续地将受检轴承进行不拆卸、不分解作出故障诊断 ,效果良好。附图 2幅 Through the bearing vibration signal testing and analysis, you can more accurately determine the bearing damage damage. According to this principle, THZJ1 railway freight car bearing fault diagnosis machine has been developed, which can automatically and continuously take the bearing under inspection without disassembly and make fault diagnosis without decomposition, and the effect is good.
