技术领域technical field
本发明涉及轴向柱塞泵织构化滑靴副油膜厚度测试装置。The invention relates to a device for testing the thickness of an oil film on a textured sliding shoe pair of an axial plunger pump.
背景技术Background technique
轴向柱塞泵作为液压系统的核心动力元件之一，因其具有结构紧凑、单位体积输出功率大、额定压力高、流量大等诸多优势，在各种机械装备中得到广泛的应用。滑靴副作为轴向柱塞泵的关键摩擦副之一，是决定轴向柱塞泵使用寿命和效率的主要因素。研究高速重载工况下滑靴副的润滑机理对于分析整个轴向柱塞泵的可靠性、运转精度、寿命等至关重要。轴向柱塞泵的能量损失来源于摩擦副，而滑靴副因磨损导致的机械零部件失效大约占40%以上。传统控制摩擦的方法是：润滑油的选择、摩擦副材料的配对以及表面涂层技术的应用。As one of the core power components of the hydraulic system, the axial piston pump is widely used in various mechanical equipment because of its compact structure, large output power per unit volume, high rated pressure, and large flow rate. As one of the key friction pairs of the axial piston pump, the sliding shoe pair is the main factor determining the service life and efficiency of the axial piston pump. Studying the lubrication mechanism of the sliding shoe pair under high-speed and heavy-load conditions is very important for analyzing the reliability, running accuracy, and life of the entire axial piston pump. The energy loss of the axial piston pump comes from the friction pair, and the failure of the mechanical parts caused by the wear of the slipper pair accounts for more than 40%. The traditional methods of controlling friction are: the selection of lubricating oil, the matching of friction pair materials and the application of surface coating technology.
目前，大多数学者对织构化滑靴副润滑特性研究范围仍局限于采用数值模拟的方法，这种方法的缺点是只能以理论公式为依据，没有实际的实验验证，理论结论不具有完全的说服性，而且容易出现误差。随着高精度油膜厚度位移传感器等测试手段的引入，国内外研究人员提出了许多微米级润滑油膜厚度的测量方法。在实际工况下，由于滑靴与斜盘间的油膜厚度只有几个微米，且测量区域存在高压、高温以及油液污染等恶劣环境，所以油膜厚度的测量要求比较高。为了提高油膜厚度测量的准确性和精度，国内外针对滑靴副油膜厚度测试的相关试验台展开研究，主要采用简化或改制柱塞泵的结构，仍然存在较大的局限性，主要体现在滑靴的运动状态比较复杂，很难与实际泵中滑靴的运动状况相吻合，不能真实地模拟滑靴副的润滑状态，导致滑靴副油膜厚度测试结果存在较大误差。At present, the research scope of most scholars on the lubrication characteristics of textured sliding shoe pairings is still limited to the method of numerical simulation. The disadvantage of this method is that it can only be based on theoretical formulas without actual experimental verification, and the theoretical conclusions are not complete convincing and prone to errors. With the introduction of high-precision oil film thickness displacement sensors and other testing methods, researchers at home and abroad have proposed many measurement methods for micron-scale lubricating oil film thickness. In actual working conditions, since the thickness of the oil film between the sliding shoe and the swash plate is only a few microns, and there are harsh environments such as high pressure, high temperature, and oil pollution in the measurement area, the measurement requirements for the thickness of the oil film are relatively high. In order to improve the accuracy and precision of the oil film thickness measurement, domestic and foreign researches have been carried out on the related test benches for the oil film thickness measurement of the sliding shoe pair. The structure of the simplified or modified plunger pump is mainly used. The motion state of the shoe is relatively complicated, and it is difficult to match the motion state of the slipper shoe in the actual pump, and the lubrication state of the slipper pair cannot be truly simulated, resulting in large errors in the test results of the oil film thickness of the slipper pair.
