摘　　要：外啮合齿轮泵为一种常用的定量泵,它的主要优点是:结构简单,重量轻,体积小,耐冲击,耐磨损,产生真空能力非常强,对恶劣工况的适应性强,抗污染能力强,工作可靠等。其缺点为流量脉动和困油现象突出,噪声大,径向力大等。该文通过Fluent流场仿真分析以及理论分析总结了径向力的计算方法以及减小径向力的措施。External gear pump is a kind of common used fixed delivery pump,its main advantages are as follows:simple structure,light weight,small size,impact resistance,wear resistance,strong ability to produce a vacuum,good adaptability to bad working condition,strong anti-pollution ability,reliable work,etc.The disadvantages are that the phenomena of flow pulsation and oil trapping are outstanding,also it has the problem of high noise and big radial force.Flow field simulation and theoretical analysis are carried out by using Fluent code,as a result,the method of calculating the radial force and the measures of reducing the radial force are summarized.
