【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。
[Abstract]:The abrasive particles produced by the gear friction pair carry the characteristics of various wear mechanisms which change with the wear process and finally show the evolution behavior of the abrasive particles which reflects all the information of gear wear. The study of the evolution of abrasive particles in the process of wear is helpful to reveal the interaction of wear mechanism and improve the accuracy of gear wear diagnosis results. Through the experimental platform of small gear transmission system, the operating conditions of industrial units are simulated, and the abrasive particles and physicochemical data in lubricating oil are obtained by oil analysis technology in the whole life cycle of gear system. The obtained wear particles were classified and the percentage of each type of wear particles in each monitoring stage was counted and the changing trend of each type of wear particles was analyzed. The results show that the fatigue wear mechanism is the main wear mechanism of gear transmission system, and the fatigue abrasive particles and fatigue peeling occupy a large proportion, and fatigue wear can promote abrasive wear and corrosion wear. The production of sliding wear particles indicates that the tooth surface wear has become more serious, the oxide abrasive particles mainly come from the abrasive particles produced by other wear mechanisms, and the increase of oil moisture is the main reason for the transformation of other types of abrasive particles into oxide abrasive particles. The black oxide is derived from the shedding material of tooth surface fatigue region under poor lubrication conditions, which can be considered as a result of the transformation of fatigue abrasive particles, which reflects the serious wear of gear transmission system.
