Wavelet Transform Algorithm and Its Application in Fault Diagnose of Gear and Rolling Axletree

小波分析算法研究及在齿轮与滚动轴承故障诊断中应用

Gear box is an important transmission part of rolling mills, but the design is always nonstandard.

轧机齿轮机座是轧制设备中的重要的传动部件, 而齿轮机座的设计往往是非标准的.

Vibration fault feature of gear and rolling axletree is analyzed. By using the decomposition and reconstruction algorithm of wavelet transform, the fault feature signal of gear and rolling axletree are extracted availably and the results of experimentation are obtained.

分析了齿轮与滚动轴承故障振动信号的特征，利用小波变换的分解和重构算法，有效地提取出齿轮与滚动轴承故障特征信号，得到实验结果。

Making use of the technology to monitor and diagnose the key equipment of high speed wire rod rolling mill, such as finish rolling unit, triple increase gear, gripping roller and wire spinning machine, the satisfied effect is reached.

运用该技术对高速线材轧机设备中的精轧机组、三重式增速箱、夹送辊及吐丝机等关键设备进行监测及诊断，取得较满意的效果。

The said k value calculated by using the current formulae is not very accurate somewhat, so that the accuracy of gear teeth would be reduced to two or three grades after cold rolling by having relatively large amount of errors.

而目前国内外所用的凸起系数K的计算公式所得出的K值误差较大，冷轧后齿轮精度下降2&3级。

This paper introduces the principle of fault diagnosis of gear, and explains the method of fault diagnosis of gear through the instance of fault diagnosis of uncoiler gear in Cold Rolling Plant and further elucidates the application of the technique of fault diagnosis of gear on-site.

简述了齿轮故障诊断的原理，并通过冷轧厂开卷机齿轮故障的诊断实例，阐述了齿轮故障诊断的方法，并进一步说明了齿轮故障诊断技术在现场中的应用。
