摘要
齿轮箱润滑油液中的磨粒携带了大量磨损状态的信息,通过在线监测传感器能监测出油液中磨粒的相关参数(尺寸、数量、生成率等),可判断或推测出齿轮箱的磨损状态。然而,目前在线监测的磨粒相关特征参数与齿轮箱磨损状态的准确对应关系还未得到深入研究。本研究首先采用离线检测的方法验证了在线监测传感器的可靠性,然后通过自主研制的试验台进行了齿轮箱全寿命加速试验,根据不同尺寸磨粒数量、磨粒生成率等的变化趋势对齿轮箱磨损程度做出了预判;最后采用铁谱分析法进一步验证了在线监测齿轮箱故障的准确性。结果表明:基于油液在线监测的磨粒信息(尺寸、数量、生成率)能很好地对齿轮箱磨损状态进行判定和预测。
The wear debris in the lubricating oil carried a large amount of wear information of gearbox.Through the on-line monitoring sensor of wear debris,some important parameters of the wear debris(including size,quantity,production rate,etc)can be monitored,which can judge and speculate the wear state of gear box.At present,the accurate corresponding relation between the relative characteristic parameters of on-line monitoring wear debris and the wear state of the gear box had not been studied in depth.In this paper,firstly,the reliability of the wear debris sensor was verified by method of off-line detection,and then through the full life test of gear box carried out by independently developed test bench,the trend of wear debris quantity and production rate in diffe-rent sizes could judge the wear degree and development trend.Finally,the iron spectrum analysis and other means were used to further verify the predictive accuracy of gearbox failure made by on-line monitoring.The results showed that the wear debris information(including size,quantity,production rate)based on oil on-line monitoring can commendably judge and forecast the wear state of gear box.
