Description

球面滚子轴承
技术领域
本发明涉及一种球面滚子轴承。
背景技术
球面滚子轴承具有两列对称滚子、一个共用的球面外圈滚道和与轴承轴线成一定角度倾斜的两个内圈滚道。外圈滚道的球体的中心点位于轴承轴线上。
球面滚子轴承包括一个或两个窗型(window type)或叉型(prong type)的保持架。
球面滚子轴承还可以包括浮动的引导环或中心固定的挡边(/凸缘)(flange)或肋，浮动的引导环或中心固定的挡边或肋引导未负载的滚子，以使它们以最佳的轴向位置进入负载区域。浮动的引导环的中心位于内圈上或(一个或多个)保持架上。
浮动的引导环防止未负载的滚子在轴向上朝向轴承的中心运动，以使它们在进入负载区域时不会在滚道之间被挤压。
改进是可能的。
发明内容
因此，本发明的特别目的是提供一种球面滚子轴承，所述球面滚子轴承具有内圈、外圈、用于在配置于所述内圈和所述外圈上的滚道上滚动的滚子以及用于将所述滚子保持为彼此间隔开的保持架。根据本发明，所述保持架包括环形芯和多个杆，所述环形芯和所述多个杆界定(/限定)用于所述滚子的多个腔格(/兜孔)(pockets)，所述环形芯包括两个侧面，所述杆从所述两个侧面在轴向上(/沿轴向)向外突出。
所述内圈和所述外圈能够绕着轴承轴线XX’相对于彼此旋转。
仍然根据本发明，所述环形芯还包括多个间隔元件，所述多个间隔元件从所述侧面突出并且被设计为与所述滚子的侧面接触，以防止所述滚子在轴向上朝向所述轴承的中心运动(/移动)。
由于本发明，防止未负载的滚子朝向轴承的中心过多运动，使得没有滚子的挤压或滚道的损坏。
由于本发明，所述球面滚子轴承比现有技术中的球面滚子轴承轻且便宜。
根据本发明的有利但非强制性的其他方面，这种球面滚子轴承可以包含以下特征中的一个或多个：
-所述保持架还包括两个环形边，所述环形边将所述杆的在轴向上位于同一侧的端部连接在一起；
-所述间隔元件与所述环形芯一体地形成，或者所述间隔元件是嵌(/埋设)在所述环形芯中的球(/球体)；
-所述间隔元件以相对于所述环形芯具有或不具有自由度的方式被保持在所述环形芯内；
-所述间隔元件由金属或陶瓷材料制成；
-所述环形芯的侧面是平坦的并且相对于所述轴承轴线XX’倾斜小于或等于90°的角度A；
-每个滚子能够与一个或两个间隔元件接触；
-所述保持架由合成材料制成。

具体实施方式
图1和图2示出了包括内圈4和外圈3的球面滚子轴承2，两个圈能够绕着纵向轴线XX′旋转，纵向轴线XX′是轴承的对称轴线。
在下文中，词语轴向或在轴向上是指平行于轴线XX’的方向，词语径向或在径向上是指垂直于轴线XX’的方向。
球面滚子轴承2还包括保持架1，用于将球面滚子5保持为彼此间隔开。滚子配置成在轴向上相邻的两列。
外圈3在其内径向圆周具有呈截球形的滚道，并且球面滚子可以在该滚道上滚动。
内圈4在其外径向圆周具有两个滚道，每个滚道呈截球形，并且两个滚道在轴向上相邻。同一列的滚子只能够在内圈的两个滚道中的一个滚道上滚动。
有利地，保持架由合成材料制成。例如，保持架由诸如PA66或PEEK的聚合物制成。根据另一实施方式，保持架由包括这种聚合物的复合材料制成。
作为一种选择，保持架由金属材料(诸如，钢、铸铁或黄铜)制成。
如在图3至图6上看得最清楚的，保持架1包括环形芯7和多个杆9，环形芯7在周向上延伸，多个杆9从环形芯7在轴向上延伸并且在周向上成间隔地定位。环形芯7和杆9限定用于接纳滚子5的多个腔格10。环形芯7在轴向上位于保持架的中心。
每个腔格10接纳一个滚子5。
为了简明和清楚起见，图3仅示出了一个滚子，而图4至图6没有示出滚子。
每个滚子5包括外球形表面，该外球形表面设计为在内圈和外圈的滚道上滚动并且与杆9的引导表面13、14接触。每个滚子5还包括两个侧面，优选地，两个侧面是平坦的并且垂直于滚子的旋转轴线。
每个杆具有用于引导球面滚子5旋转的两个引导面13、14。每个引导面13、14呈截球形。
保持架1的环形芯7包括在周向上延伸的两个侧面11、12。杆9从两个侧面11、12在轴向上向外延伸。
优选地，侧面11、12是平坦的，并且相对于轴承轴线XX’倾斜小于或等于90°的角度A。
在本发明的一些优选实施方式中，诸如图1和图2上示出的实施方式，角度A严格地小于90°，并且优选地在45°至85°之间。
作为一种选择，在其他优选实施方式中，诸如图3至图6上示出的实施方式，角度A等于90°。
作为一种选择，侧面11、12不是平坦的，而是替代地具有弧形表面，例如呈截球形。
在图1和图2上示出的保持架的优选实施方式，保持架还包括在周向上延伸的两个环形边(/边部)(border)8。
环形边8彼此平行并且还与环形芯7平行。环形芯7在轴向上位于两个环形边8之间。
每个环形边8将杆9的在轴向上位于同一侧的端部连接在一起。
环形边8有助于将滚子5保持在腔格10内。环形边8限制滚子在腔格内在轴向上朝向轴承外侧运动。
保持架1的环形芯7包括多个间隔元件6，多个间隔元件6从侧面11、12突出并且限制滚子的轴向运动。
间隔元件设计为与滚子的侧面接触。
间隔元件防止未负载(/加载)的滚子朝向轴承的中心过多运动。归因于此，防止滚子被挤压，该挤压会阻挡轴承旋转或损坏滚子或者圈的滚道。
根据本发明的间隔元件与现有技术的引导环执行相同的功能，但这种新的解决方案的重量和成本大幅降低。
优选地，滚子的侧面是平坦的并且间隔元件呈截球形，以使一个间隔元件和一个滚子之间的接触限制为点，并且使滚子和侧面之间的摩擦保持为低的。
优选地，间隔元件由金属制成。作为一种选择，间隔元件由陶瓷材料制成。
在示出的本发明的优选实施方式中，间隔元件是嵌在保持架的环形芯7中的球(/球体)。该球体位于环形芯的厚度中，以同时从两个侧面11、12突出。
间隔元件以相对于环形芯具有或不具有自由度的方式保持在环形芯7内。该自由度可以是旋转。
在未示出的本发明的优选实施方式中，间隔元件6与保持架的环形芯一体地形成。
作为一种选择，间隔元件中的一些或全部位于滚子的侧面上。
每个滚子能够与一个或多个间隔元件接触。
在图3和图4上示出的实施方式中，每个滚子能够与一个间隔元件接触。
在图5和图6上示出的实施方式中，每个滚子能够与两个间隔元件接触。
在未示出的实施方式中，每个滚子能够与至少三个间隔元件接触。
