Abstract

本实用新型公开了一种浮动式油封,包括侧盖密封、密封环和回油孔,所述侧盖密封为浮动式,所述密封环上有沟槽,所述密封环外圈固定有弹簧,所述弹簧将密封环固定在铸件侧盖沟槽与主轴间。本实用新型提供一种浮动式油封,减少制作与安装上的精度要求,防止润滑油沿着主轴渗出,减少工作量,增加安装精度,有效弥补制作与安装的误差,提高现场工作效率。

Description

一种浮动式油封
技术领域
本实用新型专利涉及离心式真空机技术领域,具体涉及一种浮动式油封。
背景技术
由于风机加工误差和安装误差的存在,风机主轴与轴承座侧盖轴孔不能做到绝对的同心;安装后侧盖轴孔与主轴径向间隙圆周各向不一致,现场需要花费时间进行调节,因此对于现场的安装而言会更加复杂,对于经验不足者则不便于安装调整。
实用新型内容
实用新型的目的:本实用新型的目的是为了弥补现有技术的不足,提供一种提高工作效率的浮动式油封。
本实用新型采用的技术方案:一种浮动式油封,包括侧盖密封、密封环和回油孔,所述侧盖密封为浮动式,所述密封环上有沟槽,所述密封环外圈固定有弹簧,所述弹簧将密封环固定在铸件侧盖沟槽与主轴间。
作为优化,所述密封环采用哈夫间子口型式。
有益效果:本实用新型提供一种浮动式油封,减少制作与安装上的精度要求,防止润滑油沿着主轴渗出,减少工作量,增加安装精度,有效弥补制作与安装的误差,提高现场工作效率。
附图说明
图1是本实用新型的结构示意图;
图2是密封环的结构示意图。
具体实施方式
下面结合附图对本实用新型具体实施例进行详细阐述:
一种浮动式油封,包括侧盖密封1、密封环2和回油孔3,侧盖密封1为浮动式,密封环2上有沟槽,密封环2外圈固定有弹簧4,弹簧4将密封环2固定在铸件侧盖沟槽与主轴间,密封环2采用哈夫间子口型式;侧盖密封1采用具有自润滑特性的石墨材质,依靠弹簧4抱紧主轴,可以起到防止润滑油沿着主轴渗出的作用。
以上所述仅是本实用新型的优选实施方式,应当指出:对于本技术领域的普通技术人员来说,在不脱离本实用新型原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本实用新型的保护范围。
