Description

连体轴承式涡轮增压器结构
技术领域
    本发明涉及涡轮增压器的结构领域，具体为连体轴承式涡轮增压器结构。
背景技术
现有的赛车的涡轮增压器，其压气机转轮和涡轮通过主轴连接，所述主轴靠近压气机转轮、涡轮的部分分别装有浮动轴承，两个浮动轴承相互独立运转，主轴在转动过程中会受到两个浮动轴承的扭力，两个浮动轴承的转动不同步，导致主轴在转动过程中所受到的阻力大，导致主轴转速小，进而浮动轴承所受到的磨损大。 
发明内容
针对上述问题，本发明提供了连体轴承式涡轮增压器结构，主轴转动过程中，受到的轴承的阻力小，转速高，转动时轴承耐磨。
连体轴承式涡轮增压器结构，其技术方案是这样的：其包括压气机转轮、涡轮、中间体、主轴，所述主轴连接所述压气机转轮、涡轮，所述主轴靠近所述压气机转轮、涡轮的部分分别装有轴承，其特征在于：所述轴承具体为高速陶瓷滚珠轴承，所述主轴外圆套有壳套，所述壳套靠近所述压气机转轮、涡轮的部分开有轴承座孔，所述壳套套有外壳，所述外壳的内壁对应于所述轴承座孔的位置对应开有外轴承座孔，陶瓷滚珠塞装于所述对应的轴承座孔、外轴承座孔所形成的空腔内。
其进一步特征在于：所述中间体开有销轴孔，所述销轴孔的侧部开有通向所述高速陶瓷滚珠轴承的油路，所述外壳对应所述销轴孔的位置开有定位孔，销轴贯穿所述销轴孔后插装于所述定位孔内。
采用本发明的结构后，由于内壳的轴承座孔、外壳的外轴承座孔之间对应塞装有陶瓷滚珠，使得涡轮增压器的主轴两端安装了连体的两个高速陶瓷滚珠轴承，主轴转动过程中，两个高速陶瓷滚珠轴承的转动同步，受到的轴承的阻力小，转速高，且转动时高速陶瓷滚珠轴承耐磨。
附图说明
图1为本发明的主视图结构示意图。
具体实施方式
见图1，其包括压气机转轮1、涡轮2、中间体3、主轴4，主轴4连接压气机转轮1、涡轮2，主轴4靠近压气机转轮1、涡轮2的部分分别装有轴承，轴承具体为高速陶瓷滚珠轴承，主轴4外圆套有壳套5，壳套5靠近压气机转轮1、涡轮2的部分开有轴承座孔6，壳套5套有外壳7，外壳7的内壁对应于轴承座孔6的位置对应开有外轴承座孔8，陶瓷滚珠13塞装于对应的轴承座孔6、外轴承座孔8所形成的空腔内。中间体3开有销轴孔9，销轴孔9的侧部开有通向高速陶瓷滚珠轴承的油路10，外壳7对应销轴孔9的位置开有定位孔11，销轴12贯穿销轴孔9后插装于定位孔11内。
