摘　　要：提出了一种傅里叶非圆齿轮驱动的四叶片差速泵,并在叶片上安装与转动方向相同的单向阀。建立了傅里叶非圆齿轮传动模型和差速泵瞬时流量模型,采用Matlab编写了分析设计软件。利用该软件分析了相同泵结构参数下的3组典型节曲线参数对节曲线形状、差速泵瞬时流量、排量、单双泵和单向阀对脉动率的影响,并与偏心圆-非圆齿轮驱动的四叶片差速泵比较,得到双泵并联的傅里叶非圆齿轮驱动的差速泵相比偏心圆-非圆齿轮驱动的差速泵在排量相当的情况下能使脉动率降低10.3%,在叶片上安装与转动方向相同的单向阀有效地解决了困液问题。A differential velocity vane pump driven by Fourier noncircular gear was designed and the blades of pump were equipped the check valves in the same direction of rotation. Through the establishment of non-circular gears Fourier model and instantaneous flow models and design of the simulation software,we analyzed the influence of the three typical parameters on the shape of the section curve,the flow rate,displacement,pump structure and single or double pump,check valve on the blades to the pulsation rate. Dual pumps in parallel driven by the Fourier non-circular gear were compared with that driven by the eccentric gear to reduce pulsation rate 10. 3%. And the installation of the check valve can solve the problem that the liquid trapped in closed chamber.
