Abstract

本实用新型公开了一种可将轴承内圈固定在轴上的圆柱滚子轴承,包括具有圆柱孔的内圈、外圈、保持架、圆柱滚子,所述内圈外侧具有限制圆柱滚子轴向移动的双挡边,所述内圈一端具有轴向延伸段,轴向延伸段周向均布有四个径向螺纹通孔,径向螺纹通孔近轴向延伸段外侧处具有导向锥孔。

Description

可将轴承内圈固定在轴上的圆柱滚子轴承
技术领域
本实用新型涉及一种可将轴承内圈固定在轴上的圆柱滚子轴承。 
背景技术
普通轴承内圈在轴上定位一般依靠轴肩、挡圈等,在光轴上不便开设环形凹槽的情况下定位轴承比较麻烦。 
实用新型内容
本实用新型要解决的技术问题是:克服现有技术中之不足,提供一种可将轴承内圈固定在轴上的圆柱滚子轴承。 
本实用新型解决其技术问题所采用的技术方案是:一种可将轴承内圈固定在轴上的圆柱滚子轴承,包括具有圆柱孔的内圈、外圈、保持架、圆柱滚子,所述内圈外侧具有限制圆柱滚子轴向移动的双挡边,所述内圈一端具有轴向延伸段,轴向延伸段周向均布有四个径向螺纹通孔,径向螺纹通孔外端具有导向锥孔。安装轴承前,先在轴表面上加工好与紧定螺钉相配的凹坑,然后将紧定螺钉依次通过轴向延伸段上的导向锥孔和螺纹通孔旋入轴上预先加工好的凹坑中即可在轴上固定轴承内圈。 
本实用新型的有益效果是:本实用新型提供的一种可将轴承内圈固定在轴上的圆柱滚子轴承,其内圈在轴上固定简单易行。 
附图说明
下面结合附图和实施方式对本实用新型进一步说明。 
图1是本实用新型的结构示意图。 
图中:1.导向锥孔;2.径向螺纹通孔;3.轴向延伸段。 
具体实施方式
现在结合附图对本实用新型作进一步的说明。这些附图均为简化的示意图,仅以示意方式说明本实用新型的基本结构,因此其仅显示与本实用新型有关的构成。 
如图1所示的一种可将轴承内圈固定在轴上的圆柱滚子轴承,包括具有圆柱孔的内圈、外圈、保持架、圆柱滚子,所述内圈外侧具有限制圆柱滚子轴向移动的双挡边,所述内圈一端具有轴向延伸段3,轴向延伸段3周向均布有四个径向螺纹通孔2,径向螺纹通孔2外端具有导向锥孔1。 
上述实施方式只为说明本实用新型的技术构思及特点,其目的在于让熟悉此项技术的人士能够了解本实用新型的内容并加以实施,并不能以此限制本实用新型的保护范围,凡根据本实用新型精神实质所作的等效变化或修饰,都应涵盖在本实用新型的保护范围内。
