Description
技术领域
本发明涉及具有滚动体的成对径向凸缘轴承。
背景技术
具有滚动体的凸缘径向轴承是公知的。它们包括同轴的外圈和内圈,夹在两圈之间的滚动体环,从而使得两个圈之间可以相对旋转,以及凸缘,该凸缘与外圈是集成的,并且一体且采用与外圈自身相同的材料制成。由于上述凸缘与外圈是集成的,使用上更好,但轴承使用的灵活性受到限制,因为在一些不同的应用中会根据形状或材料而需要不同特性的凸缘,但是外圈和内圈具有相同的性能和技术特征。
因此,为了能够使用相同的轴承,然而对于很多的应用其需要不同的凸缘时,需要根据应用的类型生产至少外圈和凸缘的方式配备轴承的生产渠道。
考虑到较大数量的部件其标准化、生产中的节约、以及这些产品的灵活性及其生产渠道的需求渐增,相似的方法手段不能正确工作。
相同的问题在成对凸缘轴承上出现,这种轴承的典型应用是变速器(比如,汽车变速器)且更特别地在具有平行轴线的轴的情况下。
发明内容
本发明的目的在于实现具有滚动体的成对径向凸缘轴承,其可以广泛使用并克服上述的不便。
这个和其他目的及优势,根据实施例的具有滚动体的成对径向凸缘轴承而获得,会在下文更好地得到理解,这些滚动体具有如附随的独立权利要求书中的特征。
本发明的其他实施方式,优选的和/或特别有利的实施方式,根据附随的从属权利要求中的特征而说明。
附图说明
本发明现在将参考附图进行说明,其显示出了一些非限定性的实施方式,即:
-图1为具有滚动体的成对凸缘径向轴承的优选实施方式的分解透视图;
-图2为图1中成对轴承的透视截面图。
具体实施方式
参考图1和2,成对径向凸缘轴承整体用附图标记1表示。该轴承提供有滚动体41,在该例中为球。
成对轴承1包括具有旋转轴线X的第一轴承10,以及具有旋转轴线X’的第二轴承10’。轴承10、10’可具有相同或不同的尺寸。图1和2中的示例显示了具有相同尺寸的一对轴承。因此,从现在开始将要描述的特征在每一轴承采用相同的附图标记。每一个轴承10、10’包括:
-外圈20,通过外表面21径向界定并提供有内滚道22;
-内圈30,与外圈20同轴安装并位于其内部,并提供有外滚道32;
-成排的滚动体41,设置在滚道22,32内侧,以使得外圈20和对应的内圈30之间可以相对旋转。
为了将成对轴承1安装到外部的机械元件上,比如,安装到传动单元的壳体上,成对轴承1还包括凸缘50,其与外圈20集成并向着外表面21的外侧且横向于轴线X,X’径向延伸。凸缘50并非与外圈20集成的凸缘,即其与外圈非一体制成,也不与外圈20的材质相同,但其以非啮合方式与外圈20对应于组装槽23装配,组装槽通过外表面21及其等同物形成在每一个外圈20的相同外表面21、环形组装边缘24上。环形安装边缘24的轴向尺寸大体上等于,但不小于槽23的轴向尺寸,并且在每一外圈20的轴向内端上通过槽23自身而受到限制,以及在外圈20的轴向外部上通过外圈20的前表面25,横向于轴线X,X’而受到限制。
如我们可在以下说明中更好地看到,由于凸缘50以可分离的方式通过外圈20组装,针对需要不同尺寸凸缘50的不同应用来说,能够一起使用相同的外圈20以及相关的内圈30,仅仅通过将外圈20和更适于应用类型的凸缘50组装起来就可以了。换句话说,轴承10、10’的生产渠道可以总是相同的,而不管轴承自身是否具有特别的应用,且在加工的最后足以将成对轴承1和针对特定应用的凸缘50组装起来:这不仅仅带来显著的经济节约,也使得生产过程更流畅,且产品自身也获得更宽的标准化。
凸缘50包括:
-啮合装置51、51’,包括两个半环形板51、51’,分别提供有凸缘53,径向向内,并包括两个大体上半圆形的部分,比如半环形板51、51’相互独立并且部分地插入到组装槽53中,用以将凸缘50锚定在外圈20中,及
-锁定装置52,包括环形板52,通过成对的基本上圆形的轮廓限定在轴向向内的方向上,并轴向地设置在两个半环形板51、51’的后面以将相同的半环形板51、51’锁定在组装槽23中。
两个半环形板51设置在轴线X,X’的相反侧上,且外圈20,如图1和2中示例,可基于特定的应用而相同或者不同,并通过各个径向内边缘53插入到组装槽23内侧。每一个半环形板51、51’具有与组装槽23轴向厚度尺寸相等的轴向尺寸厚度,并提供有各个支撑端表面54和55。端表面54和55支撑每一个半环形板51、51’,沿着横向于表面25的相同直径平面设置,并面对着支撑其他半环形板51、51’的端表面54和55并与它们接触,从而保证了两个半环形板51、51’在槽23中组装的稳定性。
特别地,每一个半环形板51、51’的边缘53被插入到槽23之中,该槽防止了两个半环形板51、51’的轴向移动。分别设置在中心和其半环形板51、51’的相反端部上,并被设置为与另一个板的端表面54,和55接触,端表面54和55防止了每一个半环形板51、51’相对于另一个半环形板的任意相对圆周向移动。边缘53,以及槽23的底部表面为柱状,并使得半环形板51、51’旋转,但是同时一起,绕着轴线X,X’旋转,从而在组装期间可以调整半环形板51、51’的位置。
环形板52提供有成对的中心通孔57,并被锁定在外圈20的外表面21上,也即将其锁定在轴向靠近两个半环形板51、51’的位置上的边缘24上。
此外,两个边缘24,两个中心孔57都提供有各自的平整部24a和57a,抵抗旋转,平整部相互啮合从而防止环形板52相对于外圈20发生旋转,也即,防止半环形板51、51’相对于外圈20旋转。
换句话说,由于槽23中两个半环形板51、51’的啮合,两个半环形板51、51’与环形板52的锁定以及两个平整部分24a和57a的相互啮合,凸缘50完全被卡在外圈20中,不管是沿着X轴线或者绕着轴线X自身都不具有任意角度的自由度。
依然如图2所示,为了利用上述的外部机械元件来组装轴承10、10’,两个半环形板51、51’和环形板52提供有各自的通孔51a和52a,其中半环形板51的通孔51a与环形板52的通孔52a对齐。孔51a和52a绕着轴线X,X’均匀分布,且孔51a和孔52a的总数量随着应用的不同而有所不同:举例来说,在附图所示的实施方式中,每一半环形板51、51’提供有三个孔51a,而板52提供有六个孔52a。
环形板52的轴向厚度尺寸等于边缘24的轴向厚度尺寸,这样,当靠近两个半环形板51、51’放置的时候,其自由侧表面之一52b,或者相反于靠近半环形板51、51’的那个面,设置在与外圈20的前表面25共面的位置中。
关于半环形板51、51’以及环形板52的材料,可以自由选择,不管是否是轴承用的钢铁,其可用于制造外圈20和内圈30。特别地,根据凸缘50和轴承10、10’所能承受的机械应力,可以选择金属材料和塑料材料或其组合。
从上面可以清楚得知,如上所述组装的凸缘50的应用大大拓宽了成对轴承1的使用,且不管轴承10、10’的用途为何,都使得圈20和30的生产得以标准化,在时间和生产成本上都大大节约。
同样,半环形板51、51’和环形板52的轴向尺寸,在本实施方式中都是基本上相似的,其可以基于上述成对凸缘轴承1的用途而改变。如已经指出,将凸缘50组装到外圈20的可能性,以及凸缘50自身的特定技术执行使得成对轴承1的构造具有较宽的范围。
除了本发明的实施方式以外,如上所述,可以理解的是,存在大量的变形。也应该可以理解的是,示例实施方式或者多个示例实施方式仅仅是示例,并非以任意方式来限定范围、应用性或者构造。而是,前述发明内容和具体实施方式部分将为本领域技术人员提供了方便的线路图来执行至少一个示例实施方式,可以理解的是可以在示例实施方式中所述的功能和元件布置中作出各种改进,而不会偏离在附随权利要求书及其法律等同物所述的范围。
