【摘要】：针对液压柱塞泵的3对主要运动副:柱塞-缸体副(柱塞副)、缸体-配流盘副(配流盘副)、斜盘-滑靴副(滑靴副),对国内外围绕3对运动副磨损特性相关的研究进行了汇总和总结。柱塞泵运动副间隙的润滑形式为粘弹性动力润滑(EHL),磨损特性与油膜、介质、污染、运动副材料及表面形貌等密切相关。主要介绍了柱塞泵运动副的润滑磨损理论研究,影响磨损特性的运动副油膜特性相关研究成果,以及适用于柱塞泵运动副的磨损模型。对比分析了柱塞泵磨损特性研究常用的解析方法、仿真方法、实验方法,介绍了每种方法的优势及局限性。最后对影响柱塞泵运动副磨损特性的关键因素进行了总结,给出了有待解决的问题及研究方案。
[Abstract]:Three pairs of main pairs of motion pairs of hydraulic piston pump: plunger-cylinder pair (plunger pair), cylinder block-flow distribution disc pair (flow plate pair), inclined disc-slipper pair (slipper pair). The research on wear characteristics of piston pump pair is summarized and summarized. The lubrication form of piston pump pair clearance is viscoelastic dynamic lubrication (EHL), wear characteristics and oil film, medium, pollution. The material and surface morphology of motion pair are closely related. This paper mainly introduces the lubrication and wear theory of piston pump motion pair, and the related research results of oil film characteristics affecting wear characteristics of piston pump motion pair. As well as the wear model suitable for piston pump motion pair. The commonly used analytical methods, simulation methods and experimental methods in the research of piston pump wear characteristics are compared and analyzed. The advantages and limitations of each method are introduced. Finally, the key factors affecting the wear characteristics of piston pump pair are summarized, and the problems to be solved and the research scheme are given.
