摘　　要：对外啮合齿轮泵的流量脉动进行研究,着重研究齿轮泵主动轮齿数和从动轮齿数相同、不相同的情况下,齿数增多对其流量脉动的影响。结果表明:在排量相同的情况下(齿轮参数中齿数和齿宽除外,其余相同),流量脉动随齿数增多而减小。The flow pulsation of external gear pump was studied. Under different circumstances of the teeth number of active ＆ driven gear of the gear pump with same ＆ different number, the influence of increased number of teeth on its flow pulsation was emphasized. The results show that ： in the case of the same displacement （ except number of teeth and tooth width in the gear parameters, others are same）, flow fluctuation decreases with the increase in the number of teeth.

关 键 词：齿数 流量脉动 外啮合齿轮泵
