Abstract

一种具有开放式泻油槽的止推轴承,它包括带进油口和泻油槽的止推轴承,其特征是:泻油槽贯通两侧工作面。本实用新型保证了润滑油的进油流量始终不大于回油流量,并且进油压力始终大于回油压力,确保润滑油单方向性流动,同时提高了润滑油在止推面的流动润滑效果。

Description

具有开放式泻油槽的止推轴承
技术领域
 本实用新型涉及一种涡轮增压器部件,具体说是一种具有开放式泻油槽的止推轴承。
背景技术
见图2,止推轴承是涡轮增压器中压气机端的一个部件,止推轴承在涡轮增压器中的作用是,防止由于增压器工作时转子所产生的轴向力造成轴系零件相互摩擦而损坏。见图2,现有的止推轴承设计有进油油路和回油油路,工作时润滑油从进油口1进入止推轴承,并在其两侧工作面2和5形成油膜,流经止推轴承的润滑油最后从泻油槽4流出。由于润滑油的压力和流量会随着转子的转速提高而加大,当进油流量和压力大于回油流量和压力时,润滑油就会从压气机端的间隙渗出。压气机端漏油会造成涡轮增压器的早期损坏,严重时甚至会导致发动机的损毁。通常压气机端漏油现象的程度会随着转子转速的提高而变得越来越严重。经分析,机芯内部的止推轴承泻油槽浅(0.6mm),造成回油不畅是导致这一现象的主要原因之一。
发明内容
本实用新型的目的是提供一种具有开放式泻油槽的止推轴承,保证润滑油的进油流量始终不大于回油流量,并且进油压力始终大于回油压力,确保润滑油在机体内的单方向性流动,同时提高润滑油在止推面的流动润滑效果。
本实用新型的目的是通过如下技术方案实现的:它包括带进油口和泻油槽的止推轴承,其特征是:泻油槽贯通两侧工作面。
本实用新型的有益效果是:保证了润滑油的进油流量始终不大于回油流量,并且进油压力始终大于回油压力,确保润滑油在机体内的单方向性流动,同时提高了润滑油在止推面的流动润滑效果。
附图说明
图1是本实用新型的结构示意图。
图2是现有止推轴承的结构示意图。
具体实施方式
见图1,本实用新型具体结构如下:止推轴承设置左、右工作面5、2和中心轴孔3,止推轴承上同时设置润滑油进油口1和泻油槽4,泻油槽4贯通两侧工作面5、2。
