Abstract

本实用新型所述的机构密封的密封环组合件由密封环、环套和密封垫组成,设置在密封环同环套之间的密封垫不仅吸收了三者压配过程中所产生的应力,使密封环端面的平面度得以确保,同时也保证了沿密封圆周方向的密封,此外设置在密封环、环套和密封垫圆周方向且互相配合的凹槽则防止了密封环的转动,上述结构还使环套可以采用薄壁冲制工艺来制作,从而节省材料,提高工效,因此,本实用新型具有装配简单,降低成本,确保精度的特点。

Description

机械密封的密封环组合件
本实用新型涉及一种机械密封的密封环组合件。
机械密封的密封环是机械密封的核心构件,有动密封环和静密封环之分,在轴向力的作用下,动密封环同静密封环的端面接触后即形成端面密封,因此,对密封环的端面的平面度有很高的要求,公知的密封环组合件由密封环和环套组成,密封环嵌装在环套的内孔中,并形成紧配,因为环套是车制件,其内孔尺寸偏差的一致性一般来说比较难控制,当用热配法同密封环形成过盈配合对,往往出现过盈过度而使密封环端面的平面度超差,并导致端面密封破坏的情况。
本实用新型的目的是提供一种装配简单,并能确保端面平面度的机械密封的密封环组合件。
这种机械密封的密封环组合件由密封环、环套和密封垫组成,其中密封垫设置在密封环同环套之间,且密封环、环套和密封垫的圆周方向均设有互相衔合的凹槽。
下面结合附图和实施例来阐明本实用新型的具体内容。
图1:静密封环组合件的结构图;
图2:A-A剖面图;
图3:动密封环组合件的结构图;
图4:B-B剖面图。
如图所示,不论是动密封环组合件可是静密封环组合件,均由密封环1、环套2和密封垫3组成,其中密封垫3设置在密封环1同环套2之间,且密封环1、环套2和密封垫3的圆周方向均设有互相衔合的凹槽4。根据上述结均,从工艺方面考虑,环套2可采用薄壁冲制件来形成,环套2上的凹槽4则在密封垫3和密封环1压入环套2的内孔中后,再用压力加工的方法来形成。所述的密封环一般采用硬质合金或碳化硅或95瓷或石墨制作,制作密封垫3的材料可根据需要分别选用丁晴橡胶、氟橡胶、三元乙丙胶和硅橡胶。
上述结构的机构密封的密封环组合件,虽然密封环、密封垫和环套三者之间是紧配,但因密封垫的弹性吸收,在密封环上就不会产生导致平面度超差的应力,此外密封垫还保证了沿密封环圆周方向的密封,凹槽则防止了密封环的转动,因此,本实用新型所述的机械密封的密封环组合件装配简单,同时能确保端面的平面度,对环套来说还提供了一种可采用冲制工艺加工的机会,该工艺既节省材料,又保证加工精度,且生产率高。
