四明山煤矿皮带机齿轮箱故障诊断技术与应用

摘要

This paper describes the type and characteristics of gear box fault of coal mine , according to the operation condition of the selected point and decided to collect and record the measured gear box of each measuring point signal, data processing and analysis of vibration signal demodulation spectrum and power spectrum, introduced the gearbox fault type. Practical application in Siming coal mine belt gear box, through the analysis of test data, found that two instances of the gearbox fault, dismantling the results verify the reliability of the results of the analysis.%阐述了煤矿皮带机齿轮箱故障的类型和振动信号特征，根据选定的测点和决定的工况，采集和记录被测齿轮箱的各测点信号，进行数据处理，分析振动信号解调谱图和功率频谱，推出齿轮箱故障类型。在四明矿皮带齿轮箱实际应用，通过对测试数据的分析，发现2个齿轮箱故障实例，拆解结果验证了分析结果的可靠性。
