Abstract

本实用新型涉及一种涡轮增压器浮动轴承，包括浮动轴承本体，浮动轴承本体上设有贯穿浮动轴承本体的进油口，浮动轴承本体与所承载的转子轴之间设有轴腔，进油口的直径为φ4.5mm，减小进油口的直径，提高了浮动轴承的存油时间，提高了涡轮增压器的性能，螺旋润滑槽可以提高润滑油的通过性，增强了浮动轴承本体与转子轴之间的润滑效果。

Description

一种涡轮增压器浮动轴承
技术领域
本实用新型涉及一种涡轮增压器，具体地说，涉及一种涡轮增压器浮动轴承，属于机械技术领域。
背景技术
车用涡轮增压器普遍采用浮动轴承支撑转子轴。目前，浮动轴承进油口的直径一般为6mm，在停车状态时，浮动轴承的油腔内的润滑油存留时间太短，影响涡轮增压器的使用寿命。
实用新型内容
本实用新型要解决的问题是针对以上问题，提供一种能够提高存油时间的一种涡轮增压器浮动轴承。
为解决以上问题，本实用新型所采用的技术方案是：一种涡轮增压器浮动轴承，包括浮动轴承本体，浮动轴承本体上设有贯穿浮动轴承本体的进油口，其特征在于：所述浮动轴承本体与所承载的转子轴之间设有油腔。
作为上述技术方案的进一步改进：
所述浮动轴承本体两端部的内壁设有螺旋润滑槽。
所述进油口的直径为φ4.5mm。
本实用新型采取以上技术方案，具有以下优点：减小进油口的直径，提高了浮动轴承的存油时间，延长了涡轮增压器的寿命，螺旋润滑槽可以提高润滑油的通过性，增强了浮动轴承本体与转子轴之间的润滑效果。
下面结合附图和实施例对本实用新型作进一步说明。
附图说明
附图1为本实用新型实施例中浮动轴承的结构示意图；
附图2为附图1中浮动轴承的局部剖视图。
图中，
1-浮动轴承本体，2-进油口，3-转子轴，4-油腔，5-螺旋润滑槽。
具体实施方式
实施例，如图1、图2所示，一种涡轮增压器浮动轴承，包括浮动轴承本体1，在浮动轴承本体1上设有贯穿浮动轴承本体1的进油口2，进油口2的直径为φ4.5mm，浮动轴承本体1与转子轴3之间设有油腔4，油腔4内储存有润滑油，浮动轴承本体1两端部的内壁设有螺旋润滑槽5，通过进油口2向浮动轴承本体1的油腔4内供油，并进入螺旋润滑槽5内，使浮动轴承本体1与转子轴3之间产生油膜，避免高速运转时发生干摩擦。
