为研究转速、空气流量、蜂窝孔长度、对边距及空气温度对蜂窝式轴心通风器油气分离性能的影响，建立了基于质点运动学的蜂窝孔内滑油颗粒运动方程，采用龙格-库塔法求解得到颗粒运动轨迹，结合蜂窝结构几何特点给出颗粒分离判据，在给定颗粒直径分布的条件下求得蜂窝孔的分离效率，分析了各项参数对蜂窝孔分离效率的影响，并给出了分离效率与各参数之间拟合关系式。结果表明：孔长和对边距一定时，分离效率随着转速提高和通风流量减小而增加；转速和流量一定时，增大蜂窝孔长度和减小对边距均使分离效率提高；降低空气温度使分离效率提高，但影响微弱。

To study the influence of rotation speed,mass flow rate,length,edge distance of honeycomb hole and air temperature on the oil/gas separation performance of axial breather with honeycomb,the particle motion equation in honeycomb hole was established based on particle kinematics.The particle trajectory is obtained by RungeKutta methods,combined with the separation criterion,under the condition of given particle diameter distribution.The separation efficiency of the whole honeycomb was obtained.The effects of various parameters on the separation efficiency of honeycomb holes were analyzed,and the relationship between separation efficiency and parameters was given.The results show that the separation efficiency increases with the increase of rotational speed and the decrease of ventilation flow rate when the length and edge distance are fixed,while it increases with the increase of honeycomb hole length and the decrease of edge distance when the speed and mass flow are fixed.The separation efficiency increases with the decrease of air temperature,but the influence is weak.
