摘　　要：综合采用理化性能分析、铁谱分析和原子光谱分析技术等多种油液监测分析技术,对SD16型推土机变速箱润滑油的油品状态、油液中磨粒的大小、形貌及元素种类、含量等进行分析。确定变速箱合理的换油时间,并判断变速箱的磨损部位及磨损状态,为研究变速箱关键零部件的磨损规律打下基础。Several kinds of oil monitoring technologies were used for the state monitoring gearbox in the SD16 bulldo- zer including the oil chemical-physics analysis, ferrography analysis, spectrometric analysis and so on. By analyzing the Lu- bricants＇ oil state and the size, morphology and element types, content of the abrasive grains, the reasonable time to change the new lubricating oil and judge the wear parts and wear state of the gearbox is determined to is lay the foundation for the study of gearbox＇ s key parts wear rules.
