Abstract

本发明公开了一种密封圈,包括橡胶圈,该橡胶圈的内部设有弹簧圈。本发明具有以下优点:在传统密封圈内埋设有弹簧圈,增强了密封圈的强度,方便在小缝隙中进行更换;结构简单,使用方便。

Description

密封圈
技术领域
本发明涉及密封圈技术领域,尤其是一种密封圈。
背景技术
密封圈由一个或几个零件组成的环形罩,固定在轴承的一个套圈或垫圈上并与另一套圈或垫圈接触或形成窄的迷宫间隙,防止润滑油漏出及外物侵入。密封圈是一种截面为圆形的橡胶圈,因其截面为O型,故称其为O型密封圈。是液压与气压传动系统中使用最广泛的一种。一般采用丁腈橡胶、天然橡胶、氯丁橡胶、乙丙橡胶、氟橡胶、硅橡胶以及共混胶制造。
发明内容
本发明针对现有技术的不足,提出一种密封圈,结构巧妙,使用方便。
为了实现上述发明目的,本发明提供以下技术方案:一种密封圈,包括橡胶圈,该橡胶圈的内部设有弹簧圈。
进一步地,该密封圈的径向截面为圆形,该弹簧圈的直径为该圆形直径的四分之一。
与现有技术相比,本发明具有以下优点:在传统密封圈内埋设有弹簧圈,增强了密封圈的强度,方便在小缝隙中进行更换;结构简单,使用方便。
附图说明
图1为本发明密封圈的结构示意图。
具体实施方式
下面结合附图对本发明进行详细描述,本部分的描述仅是示范性和解释性,不应对本发明的保护范围有任何的限制作用。
如图1所示的一种密封圈1,包括橡胶圈2和弹簧圈3,该弹簧圈3埋设在橡胶圈2内,该密封圈1为环状结构,其径向横截面为圆形,其直径为弹簧圈3的直径的四倍。
由于在橡胶圈2的内部设有弹簧圈3,增强了密封圈1的强度,尤其是在狭小空间内更换密封圈1,容易操作。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。

Claims (2)
