城市轨道交通车辆齿轮箱油的检测与诊断

Detection and Diagnosis of Gear Box Oil of Urban Rail Transit Vehicle

针对城市轨道交通车辆齿轮箱油在运用过程中出现油色发黑、乳化或出现金属杂质等现象,以广州地铁某型车辆齿轮箱作为研究对象,通过对齿轮箱油的油液检测分析,研究齿轮箱油中的水分、酸值以及金属元素的质量分数随齿轮箱运用里程增大的变化情况。分析了各项检测指标与齿轮箱内部齿轮、轴承磨损的关系,从而提前判断齿轮箱内部零部件的磨损情况,从齿轮箱油运用状态的角度提出该型车辆齿轮箱的检修策略。

In view of the phenomenon of oil blackening,emulsification or metal impurities during the usage of urban rail transit vehicle gear box oil,taking the gear box of a certain type of vehicle in Guangzhou Metro as the research object,through the detection and analysis of the gear box oil,the relationship that how water content,acid value and metal element content of the gear box oil change with the increase of the gear box operating mileage is studied.The relationship between each detection index and gear box internal gear wheel wear and bearing wear is analyzed,so as to judge the wear of the gear box internal parts in advance.The maintenance strategy of the gear box of this type of vehicle is put forward from the perspective of the usage condition of gearbox oil.
