Extracting precisely the vibration characteristics of typical gearbox faults is a key to its diagnosis.In the paper,by a lot of experiments nine typical faults in gearbox are analyzed,including profile error,tooth breaking,symmetrical tooth wear box resonance mild bending of shaft,serious bending of shaft,axial pulse of shaft,serious unbalance of shaft,and fatigue pitting of bearing.Their characteristics in time and frequency domain are summarized.On this base,the diagnosis plan by using two kinds of time domain analysis(original time domain signal and envelope signal) and three kinds of frequency domain analysis(frequency spectrum,zoom spectrum and selective zoom envelope spectrum) is introduced ,and it provides basement for designing of intelligent gearbox diagnosis system.

准确地提取各种典型故障的特征是进行齿轮箱故障诊断的关键。通过大量的实验 ,对齿轮箱中的齿形误差、齿轮均匀磨损、箱体共振、轴轻度弯曲、断齿、轴不平衡、轴严重弯曲、轴向窜动、轴承疲劳剥落和点蚀等九种典型故障进行分析 ,总结其振动信号的时频域特征 ,并在此基础上提出采用基于建档案的两时域 (原始时域和包络时域 )三频域 (频谱、细化谱、解调谱 )的诊断方法 ,为齿轮箱智能诊断系统的研制打下良好的基础。

The influence of phase reference estimation is addressed on the gearbox diagnosis . A method of phase estimation is developed based on Wigner distribution without tachometer. The objective is to supplement the current techniques of gearbox diagnosis based on time synchronous average. The proposed method focuses on the fact that gear local faults pro- duce periodic local components in vibration signals.

The influence of phase reference estimation is addressed on the gearbox diagnosis . A method of phase estimation is developed based on Wigner distribution without tachometer. The objective is to supplement the current techniques of gearbox diagnosis based on time synchronous average. The proposed method focuses on the fact that gear local faults pro- duce periodic local components in vibration signals. Based on a simplified vibration signal model, an analytic processing is proposed to describe the principle of the method. The technique is validated using dataset from a gearbox testbed. The results show that Wigner distribution is an effective tool for the phase estimation of gearbox vibration signal.

时域同步平均是齿轮箱诊断技术的基础,目前这种方法依赖于转速传感器提供相位同步信号。探讨了在没有转速传感器的前提下,由振动信号本身得到相位过零信号的方法。建立了齿轮箱振动信号的一种简化理论模型,通过理论分析得到了一种基于Wigner分布的相位估计方法。将这种方法应用于实际的齿轮箱振动数据,证明这种方法是有效的。
