Description

机油泵壳体的密封结构
技术领域
    本实用新型涉及柴油机零部件领域,具体的说是一种机油泵密封结构。
背景技术
    柴油机的机油泵的密封一般采用的是橡胶O型圈密封方式,柴油机的机油泵安装在柴油机机体的前端安装孔内,机油泵安装面要求与机体前端贴合,其通过O型圈密封要求不渗油、漏油。原机油泵壳体前端O型圈槽设计在前面为台阶槽,在装配时和机体的机油泵安装孔前端倒角干涉,安装后部分橡胶O型圈跻出,造成机油泵安装面与机体前端不能贴合,且部分橡胶O型圈损坏,导致

机油泵齿轮粘合精度下降;
Figure 2011202386041100002DEST_PATH_IMAGE004
机油泵和机体结合处因O型圈损坏,不能完全密封而导致漏油现象较多。
实用新型内容
    本实用新型提供一种结构简单,密封可靠,安装方便的机油泵密封结构。
本实用新型解决技术问题提供如下方案:
一种机油泵壳体的密封结构,包括机油泵壳本体,所述机油泵壳体两端分别设有两连接端口,所述两连接端口的外壁上分别设有凸缘,所述凸缘上设有密封槽,所述密封槽内嵌有密封槽。
所述密封圈的截面形状为U形。
本实用新型的优点为:
本实用新型通过提供一种柴油机机油泵U型槽密封设计;解决了机体安装孔前端倒角干涉,密封圈能有效地密封不会因为挤压而损坏,有效保证密封效果。本实用新型结构简单,密封可靠。
附图说明
    图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种机油泵壳体的密封结构,包括机油泵壳本体1,所述机油泵壳体两端分别设有两连接端口2、3,所述两连接端口2、3的外壁上分别设有凸缘4,所述凸缘4上设有密封槽5,所述密封槽5内嵌有密封圈6,所述密封槽6的截面形状为U形。
