摘　　要：齿轮摩擦副产生的磨粒携带多种磨损机理产生的特征,这些特征随磨损过程不断变化,最终表现为磨粒演变行为,反映齿轮磨损的所有信息。研究磨粒在磨损过程中的演变规律有助于揭示磨损机理的交互作用,对提高齿轮磨损状态诊断结果准确性具有重要作用。通过小型齿轮传动系统实验平台,模拟工业机组运行工况,在齿轮系统全寿命周期内利用油液分析技术获取润滑油中磨粒和理化数据,对获取的磨粒进行分类并统计各类型磨粒在各监测阶段中所占的数量百分比,分析各类型磨粒的变化趋势。结果表明:疲劳磨损机理是齿轮传动系统的主要磨损机理,产生的疲劳磨粒和疲劳剥块占较大比例;疲劳磨损具有促进磨料磨损和腐蚀磨损的作用;滑动磨损磨粒的产生表明齿面磨损已趋严重;氧化物磨粒主要来源于其他磨损机理产生的磨粒,油中水分的增加是促使其他类型磨粒转变为氧化物磨粒的主因;黑色氧化物来源于润滑不良条件下齿面疲劳区域脱落材料,可认为是疲劳磨粒转变而成,反映了齿轮传动系统磨损严重。There are many features, which are produced by many types of wear mechanism, on the wear debris created in the wear operation. And these features ,which are shown as the evolution rules of wear debris in the final, can be changed follow the wear operation at the same time. According to the research of the evolution of wear debris, the interaction of wear mechanism can be revealed effectively, and the accuracy of result of motion for wear condition of gear transmission system can be improved. By the help of the small gear transmission system test platform, the working condition of the industrial units are simulated. Within the whole life cycle of the gear transmission system, the wear debris and the physicochemical data are obtained by the oil analysis technology. The obtained wear debris are classified, and the percentage of each type wear debris in motion stage are accounted, and the change tendency of each wear debris are analyzed. The results show that： fatigue wear mechanism is the main wear mechanism, and the large proportion of wear debris are fatigue wear debris and fatigue spalling particles. The abrasive wear mechanism and the corrosion wear mechanism are promoted by the help of fatigue wear mechanism. The appearance of sliding wear debris show the wear situation of gear surface become more and more serious. Oxide abrasive debris are converted mainly from the other wear debris, and the high water content in oil can explain the reason. In the poor lubrication, the spalling material from the fatigue area on the surface of gear tooth can convert to black oxide wear debris. It also can be regarded that this type debris are transformed from fatigue wear debris. And it shows the serious wear in the gear transmission system.
