Abstract

本实用新型公开一种甩油轴封结构,包括内孔、内孔的一端设置止口;内孔壁的外侧设置密封环槽,还包括进油道,所述进油道和甩油孔连通,所述甩油孔为多组,沿径向端面均布;所述进油道的端部设置储油部;所述进油道为环型;所述储油部为环形段,每个甩油孔均对应一个环形段。本实用新型的优点是:由于设置了储油部,润滑油首先进入储油部,然后从甩油孔的两侧向外运动,克服了偏心现象,因此,克服了润滑不均匀的缺陷。

Description

一种甩油轴封结构
技术领域
本实用新型涉及涡轮增压器技术领域,具体说是一种轴封结构。
背景技术
涡轮增压器的工作环境较为恶劣,需要很好的润滑才能保证增压器的工作。现有的甩油轴封如图2所示,进油通道与甩油孔连接,由于在高速旋转的情况下,润滑油右进油道向甩油孔运动过程中,会偏向一侧甩出,如箭头所示,这造成了润滑不均匀。
实用新型内容
为解决上述技术问题,本实用新型的目的是提供一种润滑均匀的甩油轴封结构,具体技术方案如下:
一种甩油轴封结构,包括内孔、内孔的一端设置止口;内孔壁的外侧设置密封环槽,还包括进油道,所述进油道和甩油孔连通,所述甩油孔为多组,沿径向端面均布;所述进油道的端部设置储油部;所述进油道为环型;所述储油部为环形段,每个甩油孔均对应一个环形段。
本实用新型的优点是:由于设置了储油部,润滑油首先进入储油部,然后从甩油孔的两侧向外运动,克服了偏心现象,因此,克服了润滑不均匀的缺陷。
附图说明
图1为本实用新型的结构示意图;
图2为现有技术示意图;
图3为储油部形状示意图。
具体实施方式
下面结合附图具体说明本实用新型,如图1和图3所示,本实用新型包括内孔5、内孔的一端设置止口3;内孔壁的外侧设置密封环槽6,还包括进油道2,所述进油道2和甩油孔1连通,所述甩油孔为多组,沿径向端面均布;所述进油道2的端部设置储油部7;所述进油道2为环型;所述储油部为环形段,每个甩油孔均对应一个环形段。
