摘　　要：针对齿轮泵存在振动与噪声的问题,提出了一种新型结构多齿轮变量齿轮泵。依据流量特性理论分析,采用MATLAB软件编写程序对瞬时流量特性进行仿真分析。结果表明:与普通外啮合齿轮泵相比,该变量泵不仅可以改变排量,使瞬时流量显著增加、流量脉动大幅降低,而且实现了对泵体振动与噪声的有效控制,具有良好的流量特性品质。Aimed at the presence of vibration and noise problems in gear pumps,a new structure of multi-gear variable gear pump was proposed. According to theoretical analysis on flow characteristics,the MATLAB software was used to program the instantaneous flow characteristic for simulation analysis. The results show that as compared with normal external gear pump,not only the displacement can be changed by the variable pump,with which the instantaneous flow increased significantly and flow pulsation enormously reduced,but also the effective control is realized of the pump vibration and noise,with good flow characteristics quality.
