摘　　要：根据流体的粘弹性 ,分析了CFRP (碳纤维增强聚四氟乙烯 )螺旋回流槽油封的密封机理 ,合理解释了该骨架油封既能满足静密封要求 ,又能满足高线速度。Based on the work mechanism of the dynamic lubrication of the viscoelastic elastic fluid, the sealing mechanism of the CFRP rotary seal with helical groove was analyzed, which reasonably explains that the seal can meet the demand of the static and dynamic sealing with high rotary speed and radical vibration.
