Description

一种圆锥滚子轴承
技术领域
本实用新型涉及轴承领域,特别涉及一种圆锥滚子轴承。
背景技术
现有的圆锥滚子轴承,一般包括有外圈、内圈,所述的外圈、内圈之间设有圆锥滚子以及用于安装圆锥滚子的保持架,圆锥滚子轴承安装时,套设在轴上,圆锥滚子直径较小的一端位于内侧,但是,这种结构的圆锥滚子轴承,其密封性差,使用时,外界杂质容易从轴承位于圆锥滚子直径较大一端进入轴承内部,而且,轴承内涂设的润滑油容易流出,从而使得圆锥滚子与外圈、内圈之间的磨损大,使用寿命短。
发明内容
本实用新型的目的:为了克服现有技术的缺陷,本实用新型提供了一种圆锥滚子轴承,其密封性好,能很好地防止外界杂质进入轴承内部的同时还能防止润滑油外泄,从而能减少圆锥滚子与外圈、内圈之间的磨损,延长使用寿命。
本实用新型的技术方案:一种圆锥滚子轴承,包括有外圈、内圈,所述的外圈、内圈之间设有圆锥滚子以及用于安装圆锥滚子的保持架,其特征在于:所述的内圈位于圆锥滚子直径较大一端延伸至外圈外,延伸至外圈外的内圈上套设有密封圈,所述的密封圈上设有密封唇,所述的密封唇与外圈端面抵触。
采用上述技术方案,通过在内圈位于圆锥滚子直径较大一端设置的密封圈,使得这种结构的圆锥滚子轴承,其密封性好,能很好地防止外界杂质进入轴承内部的同时还能防止润滑油外泄,从而能减少圆锥滚子与外圈、内圈之间的磨损,延长使用寿命。
本实用新型的进一步设置:所述的密封圈包括有环状骨架以及包覆在骨架上的密封体,所述的骨架套设在内圈上,骨架与内圈过盈配合,所述的密封唇设置在密封体内侧。
采用上述进一步设置,通过设置的骨架,使得密封圈的强度好,通过骨架与内圈过盈配合,使得密封圈的定位牢靠,而且,在安装、拆卸时不会损坏骨架上的密封体,保证密封圈的密封性能可靠。
本实用新型的再进一步设置:所述的内圈上设有肩阶,所述的骨架截面包括有与肩阶相匹配的“L”字形定位边,所述的定位边套设在肩阶上,所述的定位边外侧端向外倾斜设有弹性边,所述的弹性边的外侧端向外延伸有直边。
采用上述再进一步设置,通过设置的肩阶与定位边配合,可以方便对密封圈安装时进行定位,安装更加方便;设置的弹性边使得其与定位边之间具有一定的弹力,从而使得密封唇与外圈端面之间密封性好,定位边与内圈之间定位更加稳定;设置的直边可以使得外侧的密封体不容易产生变形,保证其密封可靠。
本实用新型的再更进一步设置:所述的密封唇的唇口向内侧弯设有翻边。
采用上述再更进一步设置,唇口弯设的翻边,既能减少唇口与外圈端面之间的磨损,又能使得唇口具有一定的弹力,使得其与外圈端面抵触更加紧密,密封性更好。
附图说明
图1为本实用新型具体实施例的结构示意图;
图2为本实用新型具体实施例中密封圈的结构示意图。
具体实施方式
如图1、2所示,一种圆锥滚子轴承,包括有外圈1、内圈2,所述的外圈1、内圈2之间设有圆锥滚子3以及用于安装圆锥滚子3的保持架6,所述的内圈2位于圆锥滚子3直径较大一端延伸至外圈1外,延伸至外圈1外的内圈2上套设有密封圈4,所述的密封圈4上设有密封唇5,所述的密封唇5与外圈1端面抵触。通过在内圈2位于圆锥滚子3直径较大一端设置的密封圈4,使得这种结构的圆锥滚子3轴承,其密封性好,能很好地防止外界杂质进入轴承内部的同时还能防止润滑油外泄,从而能减少圆锥滚子3与外圈1、内圈2之间的磨损,延长使用寿命。
本实用新型具体实施例中,所述的密封圈4包括有环状骨架41以及包覆在骨架41上的密封体42,所述的骨架41套设在内圈2上,骨架41与内圈2过盈配合,所述的密封唇5设置在密封体42内侧。通过设置的骨架41,使得密封圈4的强度好,通过骨架41与内圈2过盈配合,使得密封圈4的定位牢靠,而且,在安装、拆卸时不会损坏骨架41上的密封体42,保证密封圈4的密封性能可靠。
本实用新型具体实施例中,所述的内圈2上设有肩阶21,所述的骨架41截面包括有与肩阶相匹配的“L”字形定位边411,所述的定位边411套设在肩阶21上,所述的定位边411外侧端向外倾斜设有弹性边412,所述的弹性边412的外侧端向外延伸有直边413。通过设置的肩阶21与定位边411配合,可以方便对密封圈4安装时进行定位,安装更加方便;设置的弹性边412使得其与定位边411之间具有一定的弹力,从而使得密封唇5与外圈1端面之间密封性好,定位边411与内圈2之间定位更加稳定;设置的直边413可以使得外侧的密封体42不容易产生变形,保证其密封可靠。
本实用新型具体实施例中,所述的密封唇5的唇口向内侧弯设有翻边51,唇口弯设的翻边51,既能减少唇口与外圈1端面之间的磨损,又能使得唇口具有一定的弹力,使得其与外圈1端面抵触更加紧密,密封性更好。
