【摘要】：齿轮泵具有结构简单、工艺性好、价格低、工作可靠、对油液污染不敏感等特点,因此,应用广泛。齿轮泵有流量脉动大以及径向力不平衡的缺点,所以需要一种新的结构,在研究非圆行星齿轮传动时,发现它非常适合用作液压泵,于是,提出了内曲线行星齿轮泵。这种具有非圆齿轮传动的变容液压装置,由于有多个齿轮同时啮合,避免了单对齿轮啮合时的冲击和噪声,具有传动平稳,冲击小等特点。非圆中心轮外侧是与其啮合的行星齿轮,而行星轮又与内曲线齿圈啮合,前后是端盖,其间是密封空间。转轴使中心轮转动,并带动行星齿轮自转与公转,导致密封空间容积变化,产生吸液与排液,实现泵的功能。该泵具有排量大、对油液的污染敏感性低及噪音小等特点。本文首先介绍了内曲线行星齿轮泵的国内外的研究动态、水平、存在问题,研究的目的。其次,简明介绍了内曲线行星齿轮泵中非圆行星齿轮系节曲线的原理,由此根据所列方程式在Matlab中编程,得到中心轮和内齿圈的节曲线。在Proe中建立中心轮、内齿圈和行星轮的模型,并且进行装配。最后,根据模型研究腔的容积变化,由此来分析内曲线行星齿轮泵的排量和脉动情况,并设计配流盘。通过本论文的研究,可以为内曲线行星齿轮泵的设计提供依据,尤其在内曲线行星齿轮泵的排量方面,为后续研究了奠定基础。
[Abstract]:The gear pump has the characteristics of simple structure , good manufacturability , low price , reliable work and no sensitivity to oil - liquid pollution . Therefore , the gear pump has the disadvantages of large flow pulsation and unbalance of radial force , so it needs a new structure .

The invention relates to a variable - volume hydraulic device with a non - circular gear transmission , which has the characteristics of smooth transmission , small impact and the like due to the simultaneous engagement of a plurality of gears , and has the characteristics of smooth transmission and small impact . In this paper , the research progress , the level , the problems and the research purpose of the internal curve planetary gear pump are introduced . Secondly , the principle of the non - circular planetary gear train section curve of the internal curve planetary gear pump is introduced , and the section curve of the center wheel and the inner gear ring is obtained according to the listed equation in Matlab . The model of the center wheel , the inner gear ring and the planet wheel is established in Proe , and the assembly is carried out . Finally , according to the volume change of the model research chamber , the displacement and pulsation of the inner curve planetary gear pump are analyzed , and the distribution plate is designed . Through the research of this paper , we can provide the basis for the design of the inner curve planetary gear pump , especially the displacement of the inner curve planetary gear pump , which lays the foundation for the subsequent study .
