Description

滚动轴承
技术领域
本实用新型涉及一种滚动轴承，尤其是旋转连接，它由轴承内环和轴承外环组成，滚动体在所述轴承内环和所述轴承外环之间滚动地设置在所属的滚道上，其中，在滚动轴承之内设有用来限制所述滚动轴承的转角的止动件。
背景技术
这种滚动轴承-旋转连接已经有所公开。根据专业书籍“Die
Figure Y20072030698600041
(滚动轴承的运用)”(Vereinigte Fachverlage GmbH，Mainz 1995)，这种滚动轴承-旋转连接作为用于支承挖土机、起重机的摆动轴承使用或者在汽车制造业中用于铰接式客车或有轨电车，也就是说是用在那些在构造空间受到限制的情况下具有高载荷并要求具有高的运转安全性的应用领域中。这种旋转连接能够吸收轴向力、径向力、以及扭矩。此外，在医疗工程、在机器人制造业或在防御技术中也需要这种旋转连接。
这种摆动轴承作为尤其适合用来在具有小截面的情况下吸收扭应力的四点接触式轴承构成。工业机器人的关节以及其它对球轴承的支承能力和刚性有所苛求的轴承位置上优选配备交叉滚动轴承。这种轴承拥有在滚动中具有近似正方形截面的边缘，它们交替地利用偏移的轴线在滚道上滚动。这种摆动轴承例如在FR 2549174和DE-OS 1525140中有所公开。
正如已经提到的那样，这种旋转连接也被用在医疗领域中。这种旋转连接例如在DE 3627517A1中所述的那样被用于所谓的三角顶架中。在这一关联下普遍已知的是，例如由于传递数据需要借助电子线路或者由于传递液体/气体需要通过管道，所以必须对两个旋转的零件之间的角度调节加以限制。这样做是有必要的，以便于避免旋转连接通过电子线路或管道的转动而受损。因此例如在FR 2 693 102中公开了一种三角顶架，从它的图2中可以看出，借助导管的用于医疗气体或液体的输入管路通过扭转不许损坏。
该申请文件在该技术领域上公开了刚性的止动件。它们例如按照下述方式实现，即，在两个轴承内环中设置停止件作为路径界限，该停止件彼此阻止轴承环通过接触而相对地根据确定的角位旋转。
其中的缺点在于，这种机械式转角限定装置不允许轴承环旋转超过360°以外，而这一点对于多数应用情况来说恰恰是必要的。
发明内容
出于现有技术中缺点的原因，本实用新型的任务在于，为滚动轴承提供一种对其转角进行限制的方案，该限制方案尤其可以让这两个元件相对转动超过360°。
按照本实用新型，该任务按照一种滚动轴承得以解决，该滚动轴承尤其是旋转连接，由轴承内环和轴承外环组成，滚动体在轴承内环和轴承外环之间滚动地设置在所属的滚道上，其中，在滚动轴承的内部设有用来限制滚动轴承的转角的止动件。其中，止动件为曲线控制装置。
其中，根据本实用新型的进一步发展，一个轴承环设有控制槽，所属的另一轴承环设有凹口，导向元件被设置在该控制槽和该凹口中。该导向元件根据另一特征为滑座，该滑座包括滑套和从滑套中伸出的销子。
根据本实用新型另一特征，控制槽螺线形地构成并且凹口作为径向定向的长孔构成，其中，滑套在在控制槽中引导并且销子在凹口中引导。其中进一步，为达目的，在轴承环之间形成一个将轴承环分隔的平面，在该平面区域中设有曲线控制装置。在这一关联下，如果把该平面设置在轴承环滚道区域之外，那么进一步具有优点。
其中，根据本实用新型的一个特别优选的实施例，滚动体通过两个反向设置的轴向倾斜滚针轴承的轴承针形成，这两个轴向倾斜滚针轴承拥有工作盘，并且，经延长的轴承针旋转轴的交点位于轴承内环或轴承外环中。相对于已知的、按照已公开方法优选被设为四点接触式轴承或交叉滚动轴承的旋转连接而言，在应用两个倾斜滚针轴承的情况下，在具有相同或更高承载量的同时大大地降低了制造成本。
根据本实用新型另一特征，轴承外环应该在其内表面上拥有指向轴承内环的凸起部分，该凸起部分形成用于两个轴向倾斜滚针轴承的支承面。由于该几何结构的缘故，该轴承外环可以利用特别简单的方法制造。
最后，根据滚动轴承的另一特征，轴承内环在其外表面上拥有用来容纳轴向倾斜滚针轴承的凹口，螺纹环可以拧入该凹口中。通过该螺纹环可以以简单的方式和方法调节所期望的、这种旋转连接的预加载。
根据本实用新型另一特征，轴承环应该由铝制成。从中可以确保获得具有轻型结构的滚动轴承-旋转连接。
本实用新型的有益效果是，通过把已知的曲线控制装置集成到滚动轴承中可以实现为转角＞360°的情况提供止动***。其中，控制槽的长被定义为旋转连接能够在其中运动的角区。其中存在两个止动件，在它们之间可以进行摆动，其中，第一和第二止动件分别通过控制槽的起始和结束确定。两个轴承环通过导向元件彼此连接，导向元件一方面在一个轴承环的控制槽中、另一方面在另一轴承环的所述凹口中引导。利用这种方法实现两个轴承环彼此形状封闭的强制分布，其中，这两个轴承环的摆动角度彼此通过导向槽的空间扩张得到确定并且可以根据具体的个别情况而独特地配合。

具体实施方式
图1与2中展示的并以1标识的旋转连接由轴承内环2和轴承外环3组成，在它们之间设有两个彼此反向的轴向倾斜滚针轴承4。轴向倾斜滚针轴承4各自拥有一个工作轮5、6，在这两个工作轮5、6之间，在各个保持架7上引导的轴承针8在所属的未详细示出的滚道上围绕轴承轴线9滚动。在当前的实施例中，轴向倾斜滚针轴承4按照下述内容定向，即，经延长的轴承滚针8旋转轴10在轴承内环2内在点21上相交。轴承外环3拥有V形的凸起部分11，凸起部分11作为工作盘6的支承面使用。另外还有一个螺纹环12也属于旋转连接1，它可以以它的未示出的内螺纹在轴承内环2上旋拧，从而可以利用简单的方法将这两个轴向倾斜滚针轴承4处于预加载状态。显而易见，对应于轴承外环3的凸起部分11，轴承内环2的未详细示出的用来容纳这两个轴向倾斜滚针轴承4和螺纹环12的凹口必须被设置成，它们彼此相配。
正如尤其在图1、1a和2中看到的那样，轴承内环2和轴承外环3在两个倾斜滚针轴承4的区域之外按照下述内容上下校准，即，在它们之间设有一个将它们分隔的平面13，该平面13在该实施例中作为与轴承轴线9成90°分布的径向间隙构成。在该区域中设有已知的曲线控制装置，其中，在轴承外环3中设置了控制槽14。如从图3中可以看到的那样，控制槽14螺线形地构成并从轴承外环3的中心点由内向外地分布。属于曲线控制装置的凹口15被设置在轴承内环2中并且作为向着径向定向的长孔构成。正如进一步可从图1a和2中看到的那样，在螺线形控制槽14和凹口15中设有一个被描述为滑座并设有附图标记16的导向元件，它由滑套17以及从滑套17中伸出的销子18组成。其中，滑套17被安置在控制槽14中，而销子18则分布在所述的凹口15中。利用这种方法可以让轴承内环2与轴承外环3借助导向元件16形状封闭地彼此连接，从而使得转动角度通过两个止点得到限制。止点限制控制槽14的开始和结束并具有附图标记20、19。其中，导向元件16与控制槽14或凹口15按照下述内容上下校准，即，滑套17和销子18在直径方面略微相差，从而减小摩擦。如果现在将轴承外环3视为固定，那么轴承内环2按照图2所示箭头以顺时针方向旋转，并且，它的开始位置一方面通过滑套17在止点19处的定位来确定，另一方面通过销子18在长孔式凹口15的左侧末端的定位来确定。随着轴承内环2沿顺时针的继续旋转，导向元件16的销子18在凹口15内由左向右地运动，其中，轴承内环2的最终位置通过滑套17在螺线形控制槽14的止点20处的定位来确定。
