Abstract

一种防止内弹簧脱落的油封,属于机械密封件,包括外壳、密封胶圈、内弹簧,密封胶圈里端周边有弹簧卡槽,内弹簧卡套在弹簧卡槽内,其特征是弹簧卡槽开口处粘接有U形防护胶圈。在拆卸轴的相对运动过程中,由于防护胶圈的牵引作用防止内弹簧脱落,使用安全可靠。

Description

一种防止内弹簧脱落的油封
技术领域
本实用新型涉及一种机械密封件,特别是一种防止内弹簧脱落的油封。
背景技术
目前,如汽车等行业使用的机械密封件橡胶油封一般由铁皮外壳、油封主体和弹簧组成,当与其配合的轴拆卸时,由于油封唇口收缩,弹簧容易脱落,造成油封漏油。
发明内容
本实用新型的目的是为了克服上述不足之处,而提供一种使用安全可靠的防止内弹簧脱落的油封。
本实用新型的目的是这样实现的:一种防止内弹簧脱落的油封,包括外壳、密封胶圈、内弹簧,密封胶圈里端周边有弹簧卡槽,内弹簧卡套在弹簧卡槽内,其特征是弹簧卡槽开口处粘接有U形防护胶圈。
本实用新型由于采用以上结构改进,在拆卸轴的相对运动过程中,由于防护胶圈的牵引作用防止内弹簧脱落,使用安全可靠。
附图说明
图1为本实用新型结构示意图。
具体实施方式
现结合附图所示实施例对本实用新型作出详细说明。
如图1所示,一种防止内弹簧脱落的油封,包括外壳1、密封胶圈2、内弹簧3,密封胶圈2里端周边有弹簧卡槽4,内弹簧3卡套在弹簧卡槽4内,弹簧卡槽4开口处粘接有U形防护胶圈5。
