Abstract

本实用新型涉及一种密封件,尤其是一种根部包胶外露骨架油封。该油封包括骨架,骨架的外圆采用全露式结构,其中,在骨架的根部拐角处设置橡胶凸起。通过在骨架根部设置橡胶凸起,使全露式骨架具备了半露骨架的效果,提高了骨架的密封可靠性,同时使油封具有较好的散热性。

Description

根部包胶外露骨架油封 
技术领域
本实用新型涉及一种密封件,尤其是一种根部包胶外露骨架油封。 
背景技术
目前,外露骨架式油封的外圆结构一般采用如图1所示的全露骨架结构,或者如图2所示的半露骨架结构。图1中的全露骨架结构虽然散热性好,但是油封的密封效果容易受到骨架1外圆表面质量的影响;图2中半路骨架式油封的密封可靠性相比全露骨架式油封有较大提高,但半露式骨架1’及其模具加工较困难。 
实用新型内容
本实用新型的目的在于提出了一种根部包胶外露骨架油封。 
本实用新型是采用以下的技术方案实现的:一种根部包胶外露骨架油封,包括骨架,骨架的外圆采用全露式结构,其中,在骨架的根部拐角处设置橡胶凸起。 
所述橡胶凸起的截面形状可以为圆弧形。 
本实用新型的有益效果是:通过在骨架根部设置橡胶凸起,使全露式骨架具备了半露骨架的效果,提高了骨架的密封可靠性,同时使油封具有较好的散热性。 
附图说明
图1为现有技术中全露骨架式油封的半剖视图; 
图2为现有技术中半露骨架式油封的半剖视图; 
图3为本实用新型的半剖视图。 
具体实施方式
下面结合附图对本实用新型做进一步说明。 
图3为本实用新型所述的根部包胶外露骨架油封。该油封包括骨架1、弹簧2和密封唇口3,弹簧2为密封唇口3提供径向力,使密封唇口3起密封作用。骨架1的外圆采用全露式结构,保证了油封较好的散热性;同时在骨架1的根部拐角处设置橡胶凸起4,该橡胶凸起4可以起到半露骨架的效果,提高了全露式骨架1的密封可靠性。所述橡胶凸起4的截面形状可以为如图3所示的圆弧形,或其它不规则形状。 

Claims (2)

1.一种根部包胶外露骨架油封,包括骨架(1),骨架(1)的外圆采用全露式结构,其特征在于:在骨架(1)的根部拐角处设置橡胶凸起(4)。
2.根据权利要求1所述的根部包胶外露骨架油封,其特征在于:所述橡胶凸起(4)的截面形状为圆弧形。
