- “静压平衡组合式高压旋转轴油封”,为一种采用了组合式结构以实现油封体的静压平衡以及良好的偏心追随性的新型旋转轴用油封。油封主要由径向定位环(1),轴向承压板(2),径向补偿环(3),密封体(4),“0”型密封圈(5)等零件组成,其权利要求如下:1、密封体为一个分离式零件,可与径向定位环一起随轴表面的偏心摆动而摆动或径向移动。
- 2、根据权利要求“1”所述的油封,其特征是作用在密封体径向的流体静压力可完全平衡。
- 3、在密封体的外圆面与径向补偿环的内圆面之间,安设了一个“O”型密封圈。
- 4、在径向定位环(1)的内圆面与径向补偿环(3)的外圆面之间,设有足够的径向间隙,以满足密封体及径向补偿环在径向的移动。
- 5、油封工作时,共有两个动密封面:一个是密封唇口与轴表面的高速密封面,一个是径向定位环底部与轴向承压板之间的低速摆动密封面。
- 6、对于高速油封,密封唇口为一个椭圆环形面,其轴线相对于转动轴轴线有一个夹角“A”。
