摘　　要：齿轮泵中轮齿啮合几何学上的原因所造成的流量脉动及其相应的压力脉动是产生噪声的主要原因之一。本文通过对齿轮泵产生流量(压力)脉动的主要原理和影响因素进行分析,从而得到减小齿轮泵流量(压力)脉动的方法。The operating noises of the gear pump are mainly from the perturbations of mass flow rate and the pressure, which result in the error of gear teeth geometry contact during the rotation. The main reason of these perturbations and its affecting factors were investigated and analysed, and a general methodology of perturbations reducing was developed.

关 键 词：齿轮泵 流量(压力)脉动 噪声
