摘要
为探究润滑油黏度对齿轮振动特性的影响,运用传动系统仿真软件Romax建立齿轮啮合润滑模型,分析了两种不同黏度润滑油时齿轮啮合润滑油膜厚度;在齿轮运转试验台架上对使用不同黏度润滑油的两对齿轮分别进行振动试验,采集振动信号数据;利用MATLAB对振动数据进行频域处理,对比结果并从齿面润滑状态以及微凸体相互作用的角度,对两对齿轮振动结果进行分析。分析结果表明:润滑油黏度对齿轮振动有较大影响,润滑油黏度越大,齿轮啮合时齿面间的润滑油油膜越厚,齿面间不易发生干摩擦,且微凸体碰撞就越弱,从而齿轮的振动频幅越小。
To study the effect of lubricant viscosity on gear vibration,the Romax gear model was built,and the relation between lubricant viscosity and oil thickness was studied.The vibrtion tests on two pairs of gears with two different viscosity lubricant were undertaken respectively on the gear test rig,and gears vibration signal was obtained.MATLAB was applied to process the vibration signal data in frequency domain,and by comparing the lubrication state of gear with the interaction of micro convex body,the analysis on the result of lubricant viscosity on gear vibration was carried out.The conclusion indsicates that lubricant viscosity has evident effect on gear vibration.As viscosity incrases,oil film gets thicker,which leads to less oil wear,rare micro collision and less vibration amplitude.
