Abstract

本实用新型公开了一种轴用油封,包括油封本体,所述油封本体的内部具有金属骨架,所述金属骨架外硫化成型有橡胶层,所述油封的中部设有轴孔,所述轴孔的口部设有PTFE油封唇片,所述PTFE油封唇片与轴的接触面和背面分别设有螺旋回油线,所述轴孔的内壁上设有防尘唇,所述防尘唇的侧壁上粘结有无纺布。本实用新型解决传统PTFE高速油封唇片跟随性差,抱紧力大的缺陷。

Description

轴用油封
技术领域
本实用新型属于旋转轴用油封技术领域,涉及一种轴用油封。
背景技术
目前,在传统PTFE高速旋转油封的应用中,为了提高油封唇口泵油能力,一般在PTFE片与轴接触的一面加工螺旋回油线。虽然密封性能优良,PTFE片跟随性较差,与轴的抱紧力较大,增大了轴与唇片的磨损,提高了额外的功力损失。
实用新型内容
    本实用新型提供一种为了解决传统PTFE高速油封唇片跟随性差,抱紧力大的缺陷的轴用油封。
本实用新型解决技术问题提供如下方案:
一种轴用油封,包括油封本体,所述油封本体的内部具有金属骨架,所述金属骨架外硫化成型有橡胶层,其特征在于:所述油封的中部设有轴孔,所述轴孔的口部设有PTFE油封唇片,所述PTFE油封唇片与轴的接触面和背面分别设有螺旋回油线,所述轴孔的内壁上设有防尘唇,所述防尘唇的侧壁上粘结有无纺布。
本实用新型解决其技术问题所采用的技术方案是:在传统的PTFE油封唇片的反面增加螺旋回油线,回油线位置与正面回油线的位置相互等距错开。
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,一种轴用油封,包括油封本体1,所述油封本体1的内部具有金属骨架2,所述金属骨架2外硫化成型有橡胶层3,所述油封1的中部设有轴孔4,所述轴孔4的口部设有PTFE油封唇片5,所述PTFE油封唇片5与轴的接触面和背面分别设有螺旋回油线6,所述轴孔4的内壁上设有防尘唇7,所述防尘唇7的侧壁上粘结有无纺布8。
