基本情况唇型密封件尽管已经不断大量发表有关机械密封件的文献,这可能使没有经验的观察家有所误解,但毫无疑问,旋转轴应用最广泛的密封件是唇型密封件。本论文论述唇型密封件性能的一个特别重要的方面,即密封唇与旋转轴间接触荷载的测量问题。这是一个现在还没有令人满意地解决的困难问题,与机械密封件相比,有关唇型密封件接触荷载和压力的问题确实还知得非常少,特别是旋转条件下更是这样。 Basic facts Lip seals Although there has been an ongoing publication of extensive literature on mechanical seals, which may give misunderstandings to inexperienced observers, there is no doubt that the most widely used seal on rotary shafts is the lip seal. This paper addresses a particularly important aspect of the performance of lip seals, the problem of measuring the contact load between the lip and the rotating shaft. This is a difficult problem that has not been satisfactorily solved yet. The problem with the lip seals in terms of contact load and pressure, compared with mechanical seals, is indeed still very little known, especially under rotating conditions.
