Abstract

本实用新型公开了一种轴承密封圈,包括密封件和钢骨架,密封件的外侧缘为圆弧状,密封件的内侧缘上设有三个密封齿,密封齿为斜齿。本实用新型通过三个斜齿式的密封齿与齿形槽配合密封且在其间隙中填充有少量油脂,密封效果好。

Description

一种轴承密封圈
技术领域
本实用新型涉及一种密封圈,尤其是一种轴承密封圈。
背景技术
目前轴承行业密封结构分为两种,一种是非接触密封,另一种是接触式密封,接触式密封不适用于需要降低摩擦和力矩的工况,而非接触密封对防水和防尘要求比较高的环境不能适应,而用户对轴承的防水和防尘的性能要求越来越高,同时采用圆角形齿的密封泄露大,密封性能差。
实用新型内容
本实用新型的目的在于克服上述现有技术的不足,提供一种密封效果好的轴承密封圈。
为达到上述目的,本实用新型的技术方案是:一种轴承密封圈,包括密封件和钢骨架,所述的密封件的外侧缘为圆弧状,所述的密封件的内侧缘上设有三个密封齿,所述的密封齿为斜齿。
所述的密封齿的前倾角α为450~600
本实用新型的有益效果是:通过三个斜齿式的密封齿与齿形槽配合密封且在其间隙中填充有少量油脂,密封效果好。
附图说明
图1为本实用新型安装在轴承上的示意图;
图2为本实用新型的示意图;
图3为图1中A处的放大图;
图4为轴承外圈示意图。
图中:密封件1、外侧缘11、内侧缘12、密封齿13、钢骨架2、轴承外圈3、密封凹槽31、轴承内圈4、齿形槽41。
具体实施方式
下面通过实施例,并结合附图,对本实用新型的技术方案作进一步具体的说明。
如图1、图2、图3、图4所示,一种轴承密封圈,包括密封件1和钢骨架2,所述的密封件1的外侧缘11为圆弧状,所述的密封件1的内侧缘12上设有三个密封齿13,所述的密封齿13为斜齿。
所述的密封齿13的前倾角α为450~600
密封件1的外侧缘11卡设在轴承外圈3内表面的密封凹槽31内,安装牢固,三个密封齿13与轴承内圈4外表面上的齿形槽41为非接触式配合,形成迷宫密封,在密封齿13和齿形槽41的间隙中填充有少量油脂,既减小了密封齿13的磨损,又起到了良好的密封和防尘作用。

Claims (2)
