Abstract

本实用新型公开了一种用于高速列车的向心关节轴承,包括外圈、内圈、密封圈及与内圈固定连接并从内圈两端伸出的内孔销,所述内圈与内孔销为整体式的单元结构,由于改进了轴承内圈的结构从而达到取消内孔销的效果,结构简单可靠,安装方便。

Description

向心关节轴承
所属技术领域
本实用新型涉及一种向心关节轴承,尤其涉及用于高速列车的向心关节轴承。
背景技术
现有的高速列车用向心关节轴承,包括外圈、内圈及与内圈固定连接着的用于安装轴承的内孔销,内孔销从内圈的两端伸出,在内外圈间安装有密封圈,该结构的轴承虽然能够承载高速列车的冲击,但结构复杂,使用寿命不长。
发明内容
本实用新型为克服现有技术的不足,提供了一种结构简单,可靠耐用的向心关节轴承。
本实用新型采用的技术方案是:包括外圈、内圈、密封圈及与内圈固定连接并从内圈两端伸出的内孔销,所述内圈与内孔销为整体式的单元结构。
本实用新型由于改进了轴承内圈的结构从而达到取消内孔销的效果,结构简单可靠,安装方便。
具体实施方式
如图1所示的向心关节轴承包括外圈1、内圈2及安装在内外圈之间的密封圈3,将内圈2与内孔销4分体式结构改进为整体式的单元结构,改进内圈2的结构,取消了原来的内孔销4,这样使产品的结构简单,安装简洁方便。
将密封圈3与外圈1粘接在一起,将其接触部分设计为曲面状,增大与内圈2的接触面积,这样可以有效地阻止了异物的进入并且增强了轴承的密封效果。
在轴承外圈1沟道的表面粘接了一层自润滑材料5,实现自润滑功能,该材料中含有特氟隆,轴承的内圈2采用20CrMnTi表面渗碳方法,使心部有良好的韧性,能提高速冲击载荷,既实现了免维护功能,又提高了轴承的使用寿命。

Claims (3)

1、一种向心关节轴承,包括外圈(1)、内圈(2)、密封圈(3)及与内圈(2)固定连接并从内圈两端伸出的内孔销(4),其特征是:所述内圈(2)与内孔销(4)为整体式的单元结构。
2、根据权利要求1所述的向心关节轴承,其特征是:所述密封圈(3)的接触部分为曲面状。
3、根据权利要求2所述的向心关节轴承,其特征是:在所述外圈(1)沟道表面粘接一层自润滑材料(5)。
