Description

内螺纹式双球沟型关节轴承 
(一)技术领域
本实用新型涉及一种关节轴承,尤其是涉及一种内螺纹式双球沟型关节轴承。 
(二)背景技术
目前,关节轴承使用于有规律的倾斜运动、摆动运动及低下的旋转运动,广泛应用于汽车、汽轮机、印刷、纺织机械等领域。然而常规的关节轴承直接将关节球嵌置于壳体内,并在关节球和壳体之间加入润滑油以减少摩擦,然而由于关节轴承在工作时,关节球转速高时,摩擦加剧,关节轴承的工作面经常出现磨损、点蚀甚至脱落导致轴承无法正常工作。 
(三)发明内容
本实用新型的目的在于克服上述不足,提供一种运动速度高、可靠性高、耐磨性好且使用寿命长的内螺纹式双球沟型关节轴承。 
本实用新型的目的是这样实现的:一种内螺纹式双球沟型关节轴承,包含有关节球和壳体,所述关节球为中心开孔的球体,所述壳体中心开有一与关节球相匹配的通孔,所述关节球通过该通孔嵌置于壳体内,所述壳体内壁开有凹槽,所述关节球外壁上开有环形球沟,所述球沟与壳体的凹槽之间设有若干钢珠,所述壳体上连接有一伸出杆,所述伸出杆中心开有 螺孔。 
本实用新型内螺纹式双球沟型关节轴承,所述关节球材质为轴承钢,壳体材质为合金钢。 
本实用新型的有益效果是: 
本实用新型内螺纹式双球沟型关节轴承,在关节球和壳体利用钢珠的滚动摩擦替代传统的滑动摩擦,大大降低了关节轴承在工作时的摩擦力,克服了关节轴承只能低速运动的弊病,延长了关节轴承的使用寿命,且保证了关节轴承在工作中不会而摩擦力过大而出现脱落等问题,大大增加了整个关节轴承的安全可靠性。 
(四)附图说明
图1为本实用新型结构示意图。 
图中: 
关节球1、壳体2、伸出杆3、凹槽4、球沟5、钢珠6、螺孔7。 
(五)具体实施方式
参见图1,本实用新型涉及一种内螺纹式双球沟型关节轴承,包含有关节球1和壳体2,所述关节球1为中心开孔的球体,所述壳体2中心开有一与关节球1相匹配的通孔,所述关节球1通过该通孔嵌置于壳体2内,所述壳体2内壁开有凹槽4,所述关节球1外壁上开有两道环形球沟5,所述球沟5与壳体2的凹槽4之间设有若干钢珠6,所述壳体2上连接有一伸出杆3,所述伸出杆3中心开有螺孔7,所述关节球1材质为轴承钢,壳体2材质为合金钢。
