Description

向心关节轴承
技术领域
本实用新型涉及一种向心关节轴承，特别涉及一种地铁车辆扭杆用向心关节轴承。
背景技术
向心关节轴承是一种特殊结构的滑动轴承，能承受较大的负荷，广泛应用于工程液压油缸、锻压机床、工程机械、自动化设备、汽车减震器、水利机械、摆动设备、震动设备等行业；传统的向心关节轴承结构复杂，使用寿命不长。
实用新型内容
本实用新型所要解决的问题是提供一种结构简单、可靠耐用的向心关节轴承。
为了解决上述问题，本实用新型提供了一种向心关节轴承，包括：中央部为球形体的内圈，与内圈的球形体配合的外圈，设于外圈两侧的密封圈。内圈的延伸出外圈的两端为方形体，各方形体与所述球形体的连接部具有环形槽，所述密封圈的外端与该环形槽密封配合。
所述方形体上设有圆形通孔，且内圈的表面具有采用镀硬铬处理形成的镀层。各圆形通孔的中心轴线平行且与所述外圈的中心轴线垂直。
所述外圈为一次压制成型，且外圈的内表面涂有自润滑材料。
所述密封圈采用曲面结构，增大了与内圈的接触面积，增强了轴承的密封效果。
本实用新型相对于现有技术具有积极的效果：本实用新型的向心关节轴承结构简单，采用在内圈上镀硬铬处理，外圈一次挤压成型工艺和表面涂自润滑材料处理，极大的提高了向心关节轴承的使用寿命。
附图说明
为了使本实用新型的内容更容易被清楚的理解，下面根据的具体实施例并结合附图，对本实用新型作进一步详细的说明，其中：
图1为本实用新型的向心关节轴承的结构图；
图2为图1的俯视图。
具体实施方式
见图1，本实施例提供的向心关节轴承，包括：中央部为球形体的内圈1，与内圈1的球形体配合的外圈2，设于外圈两侧的密封圈3。内圈1的延伸出外圈2的两端为方形体，各方形体与所述球形体的连接部具有环形槽，所述密封圈3的外端与该环形槽密封配合。
所述方形体上设有圆形通孔11，且内圈1的表面具有采用镀硬铬处理形成的镀层。各圆形通孔11的中心轴线平行且与所述外圈2的中心轴线垂直。
所述外圈2为一次压制成型，且外圈2的内表面涂有自润滑材料（一般为石墨或聚四氟）。
所述密封圈3采用曲面结构，增大了与内圈1的接触面积，增强了轴承的密封效果。
显然，上述实施例仅仅是为清楚地说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而这些属于本实用新型的精神所引伸出的显而易见的变化或变动仍处于本实用新型的保护范围之中。
