提出轴面微椭圆孔织构油封运行时的理论分析模型,通过仿真模拟得到微孔结构参数对其性能的影响规律。结果表明:微椭圆孔轴面织构的润滑减摩性主要体现在相对运动的过程中微织构会使液膜产生显著的动压润滑效应,致使界面间形成非接触式密封和润滑状态;在研究的工况条件下,密封可靠性在微椭圆孔的方向性方面有所体现,合适的方向性能使流体在孔区流程变长,且其受边界阻挠在孔区一侧动压增强另一侧形成空化区,低压的空化区会快速抽吸即将泄漏出的流体从而提高密封可靠性,故而通过改变织构结构尺寸可控制油封的性能。为提高油封的寿命并降低泄漏率,在研究范围内,选用半轴比

The theoretical analysis model of the axial micro-elliptical hole texture oil seal is proposed. The influence of micro-pore structure parameters on its performance is obtained by simulation. The results showed that the lubrication and anti-friction property of the micro-elliptical pores shaft texture are mainly reflected which will lead to significant dynamic pressure lubrication effect of the liquid film in the relative motion process
so non-contact sealing and lubrication are formed between the interfaces. And its seal reliability is reflected in the directivity of micro-ellipses
proper directional performance makes the flow of fluid longer in the pores area under the conditions studied
and it is blocked by the boundary to make dynamic pressure increase on one side of the pores and form cavitation zone on the other side of the pores
the low-pressure cavitation zone
will quickly suck the fluid that is about to leak out
which can improve sealing reliability. Therefore
the performance of oil seal is controlled by changing the texture size. In order to improve oil seal life and reduce leakage rate
the axial surface micro-ellipses pores textured of
