摘要
从分析直齿外啮合齿轮泵的流量特性入手,采用扫过容积的方法,以主动齿轮的啮合半径为变量,建立异齿数下齿轮泵单齿流量脉动的平均流量、流量不均匀系数和流量脉动频率的公式。实例分析异齿数对流量特性的影响,并得出一些重要结论。
The paper expounds how to establish the formula for average flow of single tooth meshing pulsation flow, flow non - uniformity coefficient and flow pulsation frequency in external gear pump with different numbers of teeth indrive and driven gears by means of sweep volume method and taking meshing radius of drive gear as variable. The influencc of dilfferent numbers of teeth in drive and driven gears on flow characteristics is analyzed and some important conclusion is given.
