摘　　要：利用三维软件Solidworks对电主轴进行建模,研究在不同转速下油气润滑流体流经电主轴时的速度场分布情况;分析电主轴转速、电主轴定转子间隙对润滑流场的影响。结果表明:随着电主轴转速增加,润滑流体流出电主轴的速度不断增大,当转速超过一定值后润滑流体流场变化剧烈,且出口处流场的最大速度区域出现位置一般呈90°夹角分布;流体流经定转子间隙时,速度场在轴向上呈现先增加后减小的趋势,在径向上呈现由转子表面向定子表面递减的趋势;通过增加出口长度的方法,可以提高回流现象出现的临界转速。The model of motorized spindle was built using three-dimensional software Solidworks,the velocity distribu-tion was researched when lubricating fluid flows through the motorized spindle at different speeds,and the effect of the spindle speed and the gap between the stator and rotor of motorized spindle on the lubrication flow field was analyzed.The results show that,along with the spindle speed increasing,the lubricating fluid flow speed is increased,when the spindle speed exceeds a certain value,the lubrication fluid flow field changes dramatically and the area of maximum speed of outlet flow is generally 90 angle distribution.When fluid flows through the rotor stator gap,the velocity field in the axial direction shows first increase then decrease trend,and it presents decrease trend from the rotor surface to the stator surface in the ra-dial direction.Increasing the length of the outlet can increase the critical speed of reflux phenomenon.
