【 摘 要 】

Aiming at the problem that it is difficult to extract the characteristics of the spectroscopy group and the characteristics of the granules cannot be fully judged, based on the gear wear test, this paper proposes to extract the multi-feature parameters of the abrasive grain group and comprehensively analyze the gear wear state. Firstly, the obtained abrasive grain image is pretreated to remove the influence of the shadow area on the characteristics of the extracted abrasive grain group. Then, the abrasive grain coverage area index (IPCA), the abrasive grain length, the abrasive grain width and the abrasive grain area distribution are extracted. Finally, the characteristic parameter data values are obtained and the trend graph is drawn to determine the state of the different wear stages of the gears, this method is suitable for condition monitoring under gear wear conditions.
