【摘要】：随着液压技术的发展,高压、高速、低噪声、集成化和长寿命已经成为液压技术发展的方向。‘为了适应低碳社会国家经济发展的要求,节能环保成为了社会发展的一大主题,因此对液压元件的能耗、噪声必然提出更高的要求。轴向柱塞泵被广泛的应用在高压及其大流量的液压系统中,它具有较紧凑的结构、较高的工作效率和工作压力以及容易改变流量等特性。随着轴向柱塞泵的高压化和高速化,由于轴向柱塞泵本身的流量脉动和由此引发的压力脉动使振动和噪声问题更加引起人们的关注。因此,设计和制作一种低噪声、低能耗、大功率的新型轴向柱塞泵必然具有广阔的市场前景。本论文总结了国内外柱塞泵的研究现状,对传统及经典轴向柱塞泵的设计理论及方法进行了研究；综合分析了均流量轴向柱塞泵的基本理念、配流副结构、导轨曲线及变量原理,为平衡式均流量柱塞泵的研究提供了理论基础；对平衡式均流量轴向柱塞泵的结构原理、基本条件、运动曲线方程等理论进行了分析和推导；对柱塞泵的主要零部件如柱塞、缸体、螺旋斜盘及配流盘等进行了结构设计,并对关键零件配流盘进行了仿真分析；螺旋斜盘的表面导轨是平缓过渡的四段螺旋曲面的综合,打破了传统斜盘泵平滑斜盘导轨的思想。本论文对平衡式均流量轴向柱塞泵的结构形式作了探讨性研究,确定了泵的关键部位结构,为平衡式均流量泵的研制奠定了基础。随着新工艺和新材料的发展,低噪音低振动的平衡式均流量泵的研制将成为现实,这对推动液压技术的发展有着非常重要的意义。
[Abstract]:With the development of hydraulic technology, high pressure, high speed, low noise, integration and long life have become the direction of hydraulic technology development. Therefore, the energy consumption and noise of hydraulic components must be higher. Axial piston pump is widely used in high pressure and large flow hydraulic system, it has a more compact structure. Higher working efficiency and pressure, and easy to change the flow rate. With the axial piston pump high pressure and high speed, Because the flow pulsation of axial piston pump itself and the pressure pulsation caused by it make people pay more attention to the problem of vibration and noise, therefore, design and manufacture a kind of low noise, low energy consumption, High power new axial piston pump must have broad market prospect. In this paper, the research status of piston pump at home and abroad is summarized, the design theory and method of traditional and classical axial piston pump are studied, the basic concept of axial piston pump with average flow rate and the structure of flow distribution pair are analyzed synthetically. The guide track curve and variable principle provide the theoretical basis for the research of the balanced average flow piston pump, and analyze and deduce the structural principle, basic conditions, motion curve equation of the balanced average flow axial piston pump. The main parts of the piston pump, such as plunger, cylinder block, helical skew disk and flow distribution disk, are designed and simulated. The idea of smoothing the sloping disk guideway of the traditional tilted disc pump is broken. In this paper, the structure of the balanced average flow axial piston pump is studied, and the structure of the pump is determined, which lays a foundation for the development of the balanced average flow pump. With the development of new technology and new materials, The development of balanced flow equalizing pump with low noise and low vibration will become a reality, which is of great significance to promote the development of hydraulic technology.
