油封的结构形式很多,如何提高油封的密封质量,对机械工业来说是很重要的。由于生产需要,我们对油封进行了试验研究。现就减震器双唇口骨架油封与传统多唇油封的性能比较以及减震器双唇油封的设计制造等方面的问题作一简单介绍。一、双唇口骨架式油封与多唇油封的性能对比双唇口骨架油封(以下称之为骨架油封),作为一种新型的密封元件,不但被用于旋转轴运动的密封系统,而且国外越来越广泛地将它使用于往复轴运动的密封系统中,例如:汽车、摩托车等减振(悬挂)系统大多采用了这种结构的油封。油封的结构形式很多,现就选三种结构(见图1)作些比较,其中图1a为多唇油封,图1b、c为双唇油封。图2是在润滑油的压力为零,而轴的移动速度为
The structure of the oil seal in many ways, how to improve the seal quality of the oil seal, the mechanical industry is very important. Due to the production needs, we conducted a pilot study on the oil seal. Now on the shock absorber lip lip seal with the performance of the traditional multi-lip seals and shock absorber lip seal design and manufacture of other aspects of the problem for a brief introduction. First, the lip lip seal and multi-lip lip seal performance comparison lip lip seal (hereinafter referred to as the skeleton seal), as a new type of sealing element, not only used for rotating shaft sealing system movement, and foreign It is increasingly used in reciprocating shaft motion sealing systems, such as automotive, motorcycle and other damping (suspension) systems are mostly used in this structure of the oil seal. The structure of the oil seal is many, now choose the three structures (see Figure 1) for some comparison, in which Figure 1a multi-lip seal, Figure 1b, c lip seal. Figure 2 is the pressure in the oil is zero, while the speed of the shaft is
