【摘要】：针对齿轮泵周向泵油路径以及螺杆泵螺旋状的油路易产生泄漏的问题,设计出以莱洛三角形为截面的莱洛斜转子,大大简化了复杂的齿廓型线设计参数,提出一种直线式泵油的新型莱洛三角泵。阐述了莱洛三角泵的结构和工作原理,确定莱洛泵一个工作周期内吸排腔的对称变化。通过构建莱洛三角形模型,根据坐标变换公式计算推导并举例验证了该泵的理论排量,结合Creo和MATLAB软件研究单周期莱洛泵进出油口的流量变化。通过分析液压力,结合受力分析和有限元模拟,对转子在工况下的干涉进行检验,为该泵的进一步研究奠定基础。

[Abstract]:In order to solve the problem that the circumferential pump oil path of gear pump and the spiral oil path of screw pump are easy to leak, a Lailo oblique rotor with Lailo triangle as cross section is designed, which greatly simplifies the design parameters of complex tooth profile, and puts forward a new type of Lailo triangle pump with straight line pump oil. The structure and working principle of Lailo triangular pump are described, and the symmetrical change of suction and drainage cavity in one working cycle of Lailo pump is determined. By constructing the Lailo triangle model, the theoretical displacement of the pump is calculated and deduced according to the coordinate transformation formula and an example is given to verify the theoretical displacement of the pump. Combined with Creo and MATLAB software, the flow change of the inlet and outlet of the single cycle Lailo pump is studied. Through the analysis of liquid pressure, combined with force analysis and finite element simulation, the interference of rotor under working conditions is tested, which lays a foundation for the further study of the pump.
