摘　　要：通过对平流泵工作原理的分析,可知降低流量脉动的最终目标就是降低双柱塞推程合成速度波动。现用平流泵主传动机构采用非圆齿轮串联曲柄滑块机构,其中非圆齿轮副是影响双柱塞合成速度的关键因素。基于预期柱塞运动速度特性反解非圆齿轮副的节曲线,在综合考虑非圆齿轮传动特性和力学特性的前提下,对非圆齿轮副节曲线进行优化设计,基于范成法原理进行非圆齿轮齿廓设计,通过虚拟样机仿真验证了理论设计的正确性。实验结果显示,非圆齿轮副的优化设计有效抑制了双柱塞推程合成速度波动,可显著降低流量输出脉动。Through analyzing the principles of a constant flow pump,the output speed pulsations might be reduced in order to reduce the output flow pulsations.The serial mechanism of the non-circular gears and slider-crank mechanism was used in the pump,so the non-circular gears were the important factors to impact the composite speeds of the two plungers.Based on the expected speeds of the two plungers,the pitch curves were resolved.And then on the premise of overall consideration of the transmission characteristics and the mechanics characteristics,the pitch curves were optimized.Then the non-circular gears＇profile were designed by the generating cutting principles.At last,virtual machine simulations and actual machine tests verify that the theoretical design is correct.And the results confirm that the optimization design is very effective to reduce the output speed pulsations.
