Abstract
本公开涉及一种用于轴承组件(100)的聚合物接合环(150)。聚合物接合环被构造为将第一内圈(120A)和第二内圈(120B)一起保持到轴承组件。聚合物接合环包括外表面(152)和内表面(154),其中述外表面的整个表面包括W或E形几何形状(155)。W形几何形状包括在角部处从外表面在径向上向外延伸的一对凸缘(155A、155C)以及在聚合物接合环(150)的中间处延伸的半圆形凸起(155B)。一对凸缘被载置在第一内圈和第二内圈的锥形窄槽(G1、G2)中,并且半圆形凸起被载置于在第一内圈与第二内圈之间形成的三角形空间(600)中,以使第一内圈和第二内圈能够紧密地连接到彼此。接合环(150)由有利于使内圈(120A、120B)的组装和准确定位容易的聚合物材料制成。
Description
技术领域
本公开涉及一种用于将两个内圈结合到轴承组件的聚合物接合环。
背景技术
轴承是用于允许其运动元件进行旋转运动或线性运动的机械组件。轴承的一个示例应用是在汽车中。在汽车中,轴承位于车辆轮轴(运动元件)与车轮轮毂(静止元件)之间。
通常,两列成组的轴承组件包括外圈、运动元件(如球或滚子)、一对内圈、一对密封件以及保持件。外圈在其内侧表面上具有槽以形成用于运动元件(球/滚子)的路径(/通道)。类似地,内圈在其外表面上也具有槽以形成路径(/通道)。运动元件(球/滚子)在外圈与内圈之间放置在路径上。密封件沿着运动元件的侧部定位在外圈与内圈之间。保持件是用于将一对内圈一起接合/连接在轴承组件中的接合元件。
通常,金属保持件用于接合轴承的内圈。金属保持件在实现较小的角部半径从而以足够的接触面积与内圈充分配合方面具有制造约束。此外,金属保持件的制造也很昂贵。
美国专利8360653B2描述了具有分体式(split)内圈的双列角接触球轴承。这种轴承包括用于将内圈保持到轴承中的保持突片(retaining tab)。其中,保持突片是梳型保持架(comb cage)的一部分,其将轴向向内和径向向下的力提供到内圈上,从而将内圈保持到轴承中。然而,具有保持突片的梳型保持架的构造增加了制造工艺的复杂性。
中国专利203463491U描述了一种新型的双列圆锥滚子轴承。这种轴承包括具有用于连接圈的止动槽的环形连接件。然而,环形连接件无法与内圈建立柔性附接。
因此,需要一种用于接合轴承组件用的内圈的改进的保持件或接合元件,其不会增加制造的复杂性,易于附接并且具有成本效益。
发明内容
提供该发明内容从而以简单的方式介绍构思的选择,这在本公开的具体实施方式中进一步描述。该发明内容不意在确定主题的关键或必要发明构思,也不意在确定本公开的范围。
聚合物接合环被构造为将第一内圈和第二内圈一起保持到轴承组件。所述聚合物接合环包括外表面和内表面,其中,所述外表面的整个表面包括W或E形几何形状。所述W或E形几何形状包括在角部处从所述外表面在径向上(/沿径向/径向地)向外延伸的一对凸缘以及在所述聚合物接合环的中间处延伸的半圆形凸起。所述一对凸缘被载置在所述第一内圈和所述第二内圈的锥形窄槽中,并且所述半圆形凸起被载置于在所述第一内圈和所述第二内圈之间形成的三角形空间中,以使所述第一内圈和所述第二内圈能够紧密地连接到彼此。所述接合环由有利于使内圈的组装和准确定位容易的聚合物材料制成。

具体实施方式
为了促进对本公开的原理的理解,现在将参照附图中示出的实施方式,并且将使用特定语言来描述它们。然而,将理解的是,由此并不意图限制本公开的范围。对本公开的这种改变和进一步修改以及如在此描述的本公开的原理的被认为是本公开涉及的领域中的技术人员通常会想到的这种进一步的应用被认为是本公开的一部分。
本领域技术人员将理解,前面的总体描述和下面的具体描述是本公开的示例性和解释性的,而不意图对其进行限制。
在本公开中,诸如第一和第二等的相关术语可以用于区分一个实体与另一个实体,而不一定暗示这些实体之间的任何实际关系或顺序。
术语“包括”、“包含”或其任何其他变型旨在覆盖非排他性包含,使得包括步骤列表的过程或方法不是仅包括那些步骤,而是还可以包括未明确列出或这种过程或方法固有的其他步骤。类似地,在没有更多限制的情况下,以“包括...一个”开头的一个或多个元素(/元件)或结构或组件并不排除存在其他元件、其他结构、其他组件、附加装置、附加元件、附加结构或附加组件。在整个该说明书中,短语“在实施方式中”、“在另一实施方式中”以及类似语言的出现可以但不一定都指相同的实施方式。
除非另有定义,否则在此使用的所有技术和科学术语具有与本公开所属领域的普通技术人员通常所理解的含义相同的含义。在此提供的组件、方法和示例仅是说明性的,而并不意在限制。
本公开涉及聚合物接合环(/聚合物结合环)。聚合物接合环被构造为将第一内圈和第二内圈一起保持到轴承组件。接合环由有利于使内圈的组装和准确定位容易的聚合物材料制成。在以下部分中,可变换地使用内圈代替第一内圈和第二内圈。聚合物接合环通过注射成型制造工艺制造。特别地,聚合物接合环有助于制造过程处理以及运输,并且进一步支撑在处理自动和手动通道形成***期间施加的一个或多个力。此外,聚合物接合环还支撑与各种运输模式相关的加速载荷。
下面将参照附图详细描述本公开的实施方式。
参照图1,轴承组件100包括向内限定中空圆形区域的环形外圈110、在外圈110的中空圆形区域中在轴向上彼此相邻布置的一对内圈120(诸如,第一内圈120A和第二内圈120B)以及在圈110与120之间滚动的多个滚动体130。滚动体130可以是球形、圆形、椭圆形或锥形的。环形外圈110包括侧向表面(/外侧表面)112和内侧表面(medial surface)114,其中,整个侧向表面112包括均匀的表面,并且内侧表面114中包括两个面向内部的锥形滚道114A和114B。第一内圈120A和第二内圈120B在设计上是对称的并且分别具有面向外部的锥形滚道120A-1和120B-1,其中,面向外部的锥形滚道120A-1和120B-1用作轴承滚道(/轴承座圈)(bearing race)。面向内部的锥形滚道114A和114B与面向外部的锥形滚道120A-1和120B-1一起形成多个腔,以支撑滚动体130绕轴承组件100的轴线滚动。多个腔在圈110和120之间形成两个环形列。多个滚动体130布置在形成于环形外圈110与内圈120之间的腔(具有锥形滚道)中、在滚道上彼此相邻(一个与另一个相邻),并且其中滚动体130借助轴承保持架而相对于彼此保持均匀的距离。
另外,轴承组件100包括在轴向上彼此间隔开布置并且分别邻近于锥形滚道的一对环形密封件140(诸如,第一环形密封件140A和第二环形密封件140B)。例如,第一环形密封件140A邻近于外圈110与第一内圈120A之间的第一锥形滚道布置,而第二环形密封件140B邻近于外圈110与第二内圈120B之间的第二锥形滚道布置。轴承组件100还包括用于将第一内圈120A和第二内圈120B接合到轴承组件100的聚合物接合环150。
参照图2,聚合物接合环150包括外表面152,外表面152的整个表面具有W形或E形几何形状155,其中,W形几何形状155包括在角部处从外表面152在径向上向外延伸的一对凸缘155A、155C以及在聚合物接合环150的中间处延伸以形成两个通道156、157的半圆形凸起155B。两个通道156、157在整个外表面152上环向地(环形地)延伸。聚合物接合环150还包括内表面154,整个内表面154具有均匀的表面。聚合物接合环150由聚合物材料或弹塑性材料(elasto-plastic material)(诸如塑料、橡胶、合成树脂等)制成。另外,聚合物接合环150包括用于允许将聚合物接合环150组装到轴承组件100中的间隙158。如图2和图3中示出的,聚合物接合环150由于间隙158而不是360度圆形的(不是完全圆形的)。间隙158包括对应(subtending)一定角度的弧度。例如,如图3中所描绘的,对于聚合物接合环150的间隙158,该角度可以在26度至56度的范围。
参照图4,描绘了聚合物接合环150的截面。通过注射成型工艺制造的聚合物接合环150有助于实现用于聚合物接合环150的期望的角部半径R1、R2、R3、R4、R5、R5、R6、R7、R8、R9和R10。角部半径R1、R2、R3和R4有利于第一内圈120A和第二内圈120B与聚合物接合环150的准确定位(/准确载置/准确放置)(accurate placement),而角部半径R7、R8、R9和R10有利于使聚合物接合环150的组装容易,并且角部半径R5和R6有利于使与周围部件的组装容易。一对凸缘155A、155C的长度L与半圆形凸起155B的半径成比例。因此,半圆形凸起155B的减小的长度使在第一内圈120A和第二内圈120B中产生的对轴承组件100的径向保持力增大。
现在参照图5,描绘了聚合物接合环150的成比例的尺寸。如图所示,角部半径R1、R2、R3、R4、R5、R6、R7、R8、R9和R10小于聚合物接合环150的厚度T。角部半径R1、R2、R3、R4、R5、R6、R7、R8、R9和R10被构造为与聚合物接合环150的厚度T的比例在例如R0.1T至0.8T的范围(即,角部半径R1、R2、R3、R4、R5、R6、R7、R8、R9和R10与聚合物接合环150的厚度T的比在0.1至0.8的范围内)。一对凸缘155A、155C的长度L与半圆形凸起155B的半径R成比例。一对凸缘155A、155C的长度L被构造为与厚度T的比例在例如1.6T至4T的范围,而半圆形凸起155B的半径R被构造为与厚度T的比例在例如R1T至3.8T的范围。半圆形凸起155B的长度L被构造为与厚度T的比例在例如1.2T至4T的范围内。聚合物接合环150的宽度W被构造为在例如8T至16T的范围,而一对凸缘155A、155C的宽度W在例如0.8T至2T的范围。
现在参照图6和图7中示出的轴承组件,第一内圈120A和第二内圈120B分别包括近端401、403和远端402、404,其中,与第一内圈120A和第二内圈120B的近端401、403相比,远端402、404的尺寸较大。第一内圈120A和第二内圈120B包括分别位于第一内圈120A和第二内圈120B的近端401、403处的钩状轮廓H1和H2。其中,钩形轮廓H1和H2包括锥形窄槽G1和G2。
参照图8,要注意的是,当第一内圈120A和第二内圈120B在轴承组件中彼此相邻布置时,第一内圈120A和第二内圈120B的钩形轮廓H1和H2形成三角形空间600。换句话说,当第一内圈120A和第二内圈120B彼此相邻地布置到轴承组件100时,第一内圈120A和第二内圈120B的轴向近端边缘彼此结合,使得它们之间形成三角形空间600。
为了有利于第一内圈120A和第二内圈120B的紧密接合,聚合物接合环150在轴承中空圆形区域(如图1中示出的)中定位在第一内圈120A和第二内圈120B的正下方。因此,在第一内圈120A和第二内圈120B在轴承组件100中彼此相邻布置时,一对凸缘155A、155C载置且紧密地配合到第一内圈120A和第二内圈120B的锥形窄槽G1和G2中,并且半圆形凸起155B载置在形成在第一内圈120A与第二内圈120B之间的三角形空间600中。半圆形凸起155B使聚合物接合环150朝向保持第一内圈120A和第二内圈120B的轴向保持能力增大。为了实现使聚合物接合环150与内圈120A和120B紧密附接,凸缘155A被载置到锥形窄槽G1中,使得第一内圈120A的钩形轮廓H1沿着聚合物接合环150的通道156定位,并且凸缘155B被载置到锥形窄槽G2中,使得第二内圈120B的钩形轮廓H2沿着聚合物接合环150的通道157定位。
图9示出了根据本公开的一个示例性实施方式的具有聚合物接合环150的轴承组件100。在图9中,示出了描绘具有聚合物接合环150的轴承组件100的高度、宽度和深度的立体图。
在此公开的聚合物接合环在制造工艺、处理和运输期间为轴承提供了柔性功能。与凸缘和锥形窄槽的接合防止第一内圈和第二内圈分离。位于第一内圈与第二内圈之间的三角形空间处的半圆形凸起有助于增大在第一内圈和第二内圈中产生的径向保持力。聚合物环由聚合物材料制成,结果,与现有的制造方法相比,降低了总制造成本。另外,聚合物环有利于使内圈的组装和精确定位容易,并且相应地有利于使对准容易。
虽然已经使用特定的语言来描述本公开,但不意在由于相同的语言而引起任何限制。对于本领域技术人员将显而易见的是,可以对该方法进行各种作业修改,以实现如本文教导的发明构思。
附图和前面的描述给出了实施方式的示例。本领域技术人员将理解,所描述的元件的一个或多个可以很好地组合成单个功能元件。作为一种选择,某些元件可以被分成多个功能元件。来自一个实施方式的元件可以被添加到另一实施方式。例如,本文描述的过程的顺序可以改变,并且不限于本文描述的方式。此外,任何流程图的动作无需按照所示的顺序实现,也无需必须执行所有动作。而且,不依赖于其他动作的那些动作可以与其他动作并行地执行。实施方式的范围绝不受这些具体示例的限制。可以进行各种变型,无论说明书中是否明确给出,诸如结构、尺寸和材料使用上的差异。实施方式的范围至少与所附权利要求书所给的范围一样宽。
