摘　　要：滚动轴承早期故障存在特征不明显、信号微弱、信噪比低、故障难以识别等特点。根据轴承振动机理和频率特性,从发展现状和常用方法 2个方面阐述了滚动轴承早期故障诊断的基本情况,并对基于量纲一化指标的滚动轴承早期故障诊断方法进行了详细论述。最后总结了滚动轴承早期故障诊断所面临的问题,并对其发展趋势进行了展望。The early fault of rolling bearings are characterized with unobvious feature,weak signal,low signal-to-noise ratio and difficult fault identification.According to vibration mechanism and frequency characteristics of bearings, the basic information about early fault diagnosis for rolling bearings are described from two aspects of development status and common methods,the early fault diagnosis method for rolling bearings are discussed in detail based on dimension-less indicators.Finally,the problems about early fault diagnosis for rolling bearings are summarized,and its develop-ment tendency is prospected.
