【摘要】 行星齿轮泵是基于内外啮合齿轮泵理论和行星轮系理论基础上的新型齿轮泵,既传承了齿轮泵的结构紧凑、体积小、质量轻、工作可靠、价格便宜、对油液杂质不敏感、自吸能力强、维护方便等优点,又解决了流量脉动大、径向力不平衡、噪声大等难题,符合液压泵趋向高压化、大排量的现代设计理念。本文从以下几个方面对行星齿轮泵进行了研究：首先,在综合分析普通齿轮泵的工作特性之后,提出了行星齿轮泵的结构原理；基于啮合点位移及其交变规律的基础上对行星齿轮泵进行分类,并对其流量特性作了比较。其次,利用三维实体软件建立了行星齿轮泵的仿真模型,并对其各结构件进行了模态分析及齿轮运动仿真分析。此外,分析了行星齿轮泵的泄漏环节,提出了泄漏控制措施。为了捕捉行星齿轮泵的内部泄漏流场变化,利用有限元分析软件对其进行了仿真分析。最后,在已知载荷、工作条件并选定材料的基础上,建立了以流量脉动最小和体积最小为双目标的行星齿轮泵的优化数学模型,并利用优化工具箱得出了优化结果。更多还原

【Abstract】 Based on the theory of internal and external gear pump and planetary gear system, the planetary gear pump is invented. It not only inherit the gear pump’s benefits such as compact in structure, small size, lightly weight, works reliable, cheap, not sensitive to the oil impurities, strong self-absorption ability, maintain easily, etc., but also solve the flow ripple, radial force balance, strong noise and other difficulties. Planetary gear pump is in line with trend of high-pressure hydraulic pump oriented and large displacement of modern design. In this paper, the following aspects have been studied:Firstly, it analyzes the operating characteristics of common gear pump comprehensive and introduces the structural principle of the planetary gear pump. On the basis of the meshing point displacement and its alternating rules, the planetary gear pump is classified. What’s more, its flow characteristics are compared.Secondly, the solid planetary gear pump simulation model is established by tridimensional software. Then the modal analysis and gear motion simulation analysis about its structural components are given.In addition, it analyzes the leak links of planetary gear pump and provides the control measures about leakage. In order to capture the variation in the internal leakage flow field, finite element analysis software is used to do simulation analysis.Finally, in the case of the load and working conditions are known and the materials are selected, the mathematical model of planetary gear pump was established on the target of the smallest pulsating flow and minimal size.It employes optimization Toolbox for optimization design and gives the optimization results.更多还原
