Abstract

本实用新型涉及一种卧式水轮发电机组轴承端盖,它包括端盖本体、垫圈、斜孔、直孔、回流孔、羊毛毡,在端盖本体另端设有下端盖,端盖本体与下端盖通过螺栓、螺帽相连,端盖本体与下端盖之间设有空腔,在下端盖的另端设有迷宫。该轴承端盖结构简单,与传统结构相比更具科学性,能使轴承轴向达到零漏油状态。

Description

一种卧式水轮发电机组轴承端盖
技术领域
本实用新型涉及一种卧式水轮发电机组轴承端盖。
背景技术
卧式水轮发电机组中的滑动轴承两轴端是轴伸处,轴与端盖是动与静止的关系,老式轴承结构此处经常漏油,给电站的运行、维护,以及河流和周边环境的保护造成极大影响。
发明内容
本实用新型的目的就是提供一种彻底消除卧式水轮发电机组的滑动轴承轴伸处漏油现象的卧式水轮发电机组轴承端盖。
本实用新型的技术方案是这样实现的:它包括端盖本体、垫圈、斜孔、直孔、回流孔、羊毛毡,在端盖本体另端设有下端盖,端盖本体与下端盖通过螺栓、螺帽相连,端盖本体与下端盖之间设有空腔,在下端盖的另端设有迷宫。
本实用新型的优点是:1、结构简单,与传统结构相比更具科学性;2、能使轴承轴向达到零漏油状态。
附图说明
图1是本实用新型的结构示意图
图2是图1的左视剖面图
具体实施方式
如图1、图2所示,它包括端盖本体1、垫圈4、斜孔5、直孔6、回流孔8、羊毛毡9,在端盖本体1另端设有下端盖10,端盖本体1与下端盖10通过螺栓2、螺帽3相连,端盖本体1与下端盖10之间设有空腔11,在下端盖10的另端设有迷宫7。
这种轴承端盖有三道密封,两道迷宫一道羊毛毡。当漏油经过第一道迷宫后其速度和压力大大减小,第一道迷宫与第二道迷宫之间有一段较长距离(正由于此,称之为双层端盖)而形成一个空腔11,经过第一道迷宫后的漏油绝大部分落入空腔11并通过上半部分的斜孔5和下半部分的直孔6回到轴承箱内;有一部分漏油会沿主轴进入第二道迷宫,该道迷宫的作用于第一道相同,减小漏油的速度和压力并且使漏油通过迷宫槽内的竖孔排到空腔11内;如此大大减小了漏油量,为了做到零漏油,在外端设置了一道羊毛毡9。
