Abstract

本实用新型带定位环油封骨架,具油封骨架,油封骨架的前端弯折有定位环,本实用新型结构简单,密封性强,在骨架油封硫化成型时可以通过定位环定位,保证油封的密封唇胶料均匀,定位环可以在油封安装时与油封座同心,易于装配,提高了油封的使用寿命。

Description

带定位环油封骨架 
(一)技术领域:本实用新型涉及一种密封装置,具体是一种带定位环油封骨架。 
(二)背景技术:目前现有油封骨架(如图1、图2),在装配时由于油封外圈的橡胶很难保证油封与油封座同心,正因为在安装时与油封座不同心,造成骨架油封轴心线不垂直,油封的密封唇会把润滑油从轴上排干,密封唇与轴之间没有油膜,导致密封唇的过度磨损,造成骨架油封早期失效和密封系统的泄露。目前市场大部分骨架油封的失效,就是因为油封在安装时与油封座不同心造成的。 
(三)发明内容:本实用新型的目的就是对以上缺点进行改进。提出一种结构简单,密封性强,可以保证骨架油封在装配时与油封座同心的带定位环油封骨架。 
本实用新型带定位环油封骨架,具油封骨架,其特征在于:油封骨架的前端弯折有定位环。 
本实用新型结构简单,密封性强,在骨架油封硫化成型时可以通过定位环定位,保证油封的密封唇胶料均匀,定位环可以在油封安装时与油封座同心,易于装配,提高了油封的使用寿命。 
(四)附图说明
图1是现有油封骨架结构示意图 
图2是现有油封骨架工作结构示意图
图3是本实用新型结构示意图 
图4本实用新型工作结构示意图 
图中,1-油封骨架,2-定位环,3-油封座,4-轴。 
(五)具体实施方式:
参见图3、图4,采用薄钢板制作油封骨架1,油封骨架1的前端弯折有定位环2。安装时,定位环2与油封座3钢性接触装配,使得在工作过程中骨架油封与油封座3同心,与轴4的轴心线垂直,易于装配,提高了油封的使用寿命。
