复合外齿轮泵齿数的选择

Gear Number Select of Compound External Gear Pump

简要介绍了复合外齿轮泵的结构原理 ,着重分析了主动轮齿数的变化对泵流量均匀性的影响。并得出了Z1=3k + 1>5N时具有较好的流量均匀性 ,供设计参考。

This paper introduces the structure principles of a compound external gear pump.Emphasis is laid on the change in number of driving gears as a function of flow homogeneity.In the discussion,the optimum flow homogeneity is deduced when z=3k+1>5N.The conclusion can offer references for the pump design.
