在线振动监测、诊断系统在行星减速机机组中的应用

Application of on-line vibration monitoring and diagnosis system in planetary reducer unit

行星减速机在运行中出现的故障前兆是隐性的,不易判断,一旦发生故障,往往即是恶性故障,将直接导致生产线停车,严重时造成行星减速机报废。在线振动监测、诊断系统的应用,通过转动部件的振动信号和特征频谱对比,为设备的故障原因分析提供了可靠的依据,为设备的大修指明了检修方向,降低风险,同时腾出了零件采购周期,减少企业设备运行维护成本,提高经济效益。

The fault precursor of planetary reducer in operation is recessive and hard to judge.Once the fault occurs,it is often malignant fault,which will directly lead to the production line shutdown and even cause the planetary reducer to be scrapped.The application of on-line vibration monitoring and diagnosis system,through the comparison of vibration signals and characteristic spectrum of rotating parts,provides a reliable basis for the analysis of equipment failure causes,points out the direction of maintenance for the overhaul of equipment,reduces the risk,frees up the procurement cycle,reduces the maintenance cost of equipment operation enterprises,and improves the economic benefits.
