本文介绍了“可更换唇口橡胶油封”的设计，试制及试验结果。
This paper introduces the design, manufacture, and testing results of rubber seals with replaceable lip.
分析了唇型密封圈（油封）漏油机理，提出了解决问题的对策方案。
The oil leak mechanism of oil-seal is analyzed, and the countermeasures to solving the problems are put forward.
在没有失稳之前，油封唇口接触宽度随油封内腔压力有明显增大，而最大接触压力先是不断增大，后由于接触宽度增大的缘故，最大接触压力开始减小。
Before the break, the width of the contact field on the air side has a great increase, but the max contact pressure increase at first and then become smaller due to the increase of the contact width.
随着安装过盈量的增大，油封唇口接触宽度不断增加，唇口最大接触压力先是有所增加，后逐渐趋于一定值。
Thirdly, along with the increase of the interference the width of the contact field on the air side become larger, but the max contact pressure increase first and then come to a constant value.
此外，对农业工程机械中的密封提出反装油封产生微泄漏，以形成对唇口接触区域清洗作用的设想。
In addition, an imagination of using the reverse setting of oil seal to produce the microleakage inord er to make clean the lip contact region using in the agricultural construction Mach...
U型圈是液压缸中最常用的油封，它是一种典型的唇口密封件，无论用于活塞还是活塞杆都能获得良好的密封效果。
It's typical lip seal, which is able to gain good seal effect no matter in piston or piston rod.
