摘要

摘要: 斜盘-滑靴副(滑靴副)的磨损会导致泵泄漏增加、效率降低,进而影响寿命.提出了一种基于弹性流体动力润滑(EHL,Elasto Hydrodynamic Lubrication)磨损模型的轴向柱塞泵滑靴副加速寿命试验方法.该方法以滑靴副的油膜分析结果为基础,综合考虑工况参数(温度/转速/压力)对滑靴副磨损的影响,揭示了影响滑靴副磨损过程的内在因素.研究以某型轴向柱塞泵为对象,首先基于提出方法,对2组不同工况下的滑靴副磨损量进行了分析,并将分析结果与长周期的磨损试验结果进行了对比,验证了磨损量分析结果的准确性,也表明本文提出的方法与模型具有可用性.然后,基于本文提出方法和磨损分析模型,对比分析了介质温度(黏度)、输出压力、转速与滑靴副磨损率的相对关系.最后,探讨了柱塞泵的磨损加速寿命试验的加速手段,以及工况对于加速比率的影响.研究结果能够用于制定柱塞泵加速磨损试验的载荷谱,以及为降低泵磨损为目的的设计优化.

Abstract: Wear of swash plate-slipper moving pair (slipper pair) of hydraulic axial piston pump results in increasing leakage, declining efficiency, and finally shorting the lifetime. An accelerated lifetime test method was presented based on the elasto hydrodynamic lubrication (EHL) wear model. As the most important factor effecting on wear process, oil film thickness of slipper pair was primarily analyzed. Running parameters (temperature/rotation speed/pressure) were integrated and considered when analyzing the wear, and the intrinsic factors affecting the wear process of sliding pair were revealed. An axial piston pump is selected as the study case. Firstly, under two different running conditions, wear amounts of slipper pair were analyzed and the analysis results were compared with long term test results, which verify the accuracy of analysis results of wear amounts and the feasibility of the method and mode. Then, based on the proposed method and wear analysis model, the relative relationship between medium temperature (viscosity), output pressure, rotate speed and wear ratio of slipper pair were analyzed comparatively. Finally, discussions about the accelerated means of piston pump when executing an wear accelerated lifetime test and the effects of working condition on acceleration ratio were given. Research result can be utilized to create the load spectrum of accelerated wear test of piston pump, and is also useful to do optimization for reducing wear of piston pump.
