Description

枢轴支架轴承及用于制造枢轴支架轴承的方法
技术领域
本发明涉及根据权利要求1的前序部分的枢轴支架轴承。本发明还涉及用于制造枢轴支架轴承的方法。
背景技术
例如，从DE 10 2005 034 739 A1已知一种通用的枢轴支架轴承。该枢轴支架轴承包括枢轴杆、即枢转元件以及安装有枢轴杆的壳体。轴承壳插入壳体中，在DE 10 2005 034739 A1的情况下，轴承壳被称为外环段。另一轴承壳保持在枢轴杆上。设计为滚针或滚子的滚动体在轴承壳之间滚动。保持在枢轴杆上并且基本上呈弯曲带状件的形式的内轴承壳在其端部处弯曲成呈朝向枢转轴线定向的凸出部的形式并且因此以形状配合的方式保持在枢轴杆上、即抵抗旋转地固定。
在EP 1 886 035 B1中描述了具有根据权利要求1的前序部分的特征的另一枢轴支架轴承。在这种情况下，斜盘被设置为枢转元件。斜盘是具有可变通过量的液压轴向活塞机的一部分。已知的设计为斜盘枢轴轴承的枢轴支架轴承包括在保持器中被引导的滚动体，其中，保持器控制器集成到枢轴轴承的滚动轴承段中。保持器控制器防止保持器滑出其在枢轴轴承中的最有利位置。
本发明基于与上述现有技术相比、特别是在制造方面进一步开发枢轴支架轴承的目的。
发明内容
根据本发明，该目的通过具有权利要求1的特征的枢轴支架轴承来实现。该目的还通过根据权利要求9的用于制造枢轴支架轴承的方法来实现。下面结合制造方法所说明的本发明的构造和优点也类似地适用于设备，也就是枢轴支架轴承，并且结合设备所说明的本发明的构造和优点也类似地适用于制造方法。
在本身已知的基本概念中，枢轴支架轴承包括：枢转元件，该枢转元件安装成在壳体中枢转；内轴承壳，滚动体在其上滚动的内轴承壳被保持在枢转元件上。根据本发明，内轴承壳沿轴承壳的周向方向、即沿枢转方向通过铆钉以形状配合的方式保持在枢转元件上。尽管给出了形状配合连接，但轴承壳可以在不造成损坏的情况下从枢转元件移除。在任何情况下，环段、即轴承壳设计为用于枢轴支架轴承的抗旋转元件。
即使在枢转元件与壳体之间传递非常大的力的应用中，铆接连接也适用于将内轴承壳永久地稳定保持在枢转元件上。例如，枢转元件是液压轴向活塞机、即液压马达或液压泵的枢轴杆或枢轴盘。
根据一个可能的实施方式，内轴承壳通过正好两个铆钉保持至枢转元件。铆钉优选地布置在内轴承壳的不被滚动体、特别是滚针或柱形滚子越过的区域中。铆钉优选地为钢铆钉。替代性地，青铜、黄铜或其他合金适用于制造铆钉。除了实心铆钉之外，还可以使用其他类型的铆钉、比如中空铆钉。铆钉的将轴承壳固定在枢转元件上抵抗旋转的头部优选地设计为埋头头部。埋头头部与轴承壳的表面齐平闭合原则上能够使滚动体滚过。
枢轴支架轴承可以按以下步骤制造：
-提供枢转元件、内轴承壳、壳体、外轴承壳和一组滚动体，该枢转元
件在弯曲表面中具有两个凹部；
-在内轴承壳中形成两个孔；
-将铆钉插入到每个孔中，即，在每种情况下制造铆钉连接；
-将内轴承壳——其包括牢固地连接至内轴承壳的铆钉——放置在枢
转元件上，使得铆钉接合在枢转元件中的凹部中；
-完成枢转元件和内轴承壳与滚动体、外轴承壳和壳体的布置，以形成枢轴支架轴承。
位于枢转元件中的凹部可以是通孔或是盲孔。在后一种情况下，铆钉优选地插入凹部中，使得尽管防止了轴承壳的移位，但是不存在防止铆钉从凹部拉出的固定功能。例如，当铆钉的相对于轴承壳突出的部分、即铆钉足部具有与枢转元件中的相关联的凹部相同的筒形形状时，就是这种情况。
一般而言，这意味着关于在位于枢转元件与内轴承壳之间的切向平面中、特别是在基本带状的轴承壳的周向方向上或在枢转轴线的纵向方向上作用的载荷，铆钉与枢转元件之间存在形状配合连接，而同时铆钉保持能够沿其纵向方向、即垂直于切向平面移位。因此，铆钉连接仅存在于铆钉与内轴承壳之间，而不存在于铆钉与枢转元件之间。
为了将内轴承壳紧固至枢转元件，内轴承壳必须与插入的铆钉一起稍微弹性变形。一旦铆钉足部卡入凹部中，内轴承壳就被固定成抵抗旋转及从枢转元件脱落，并且被精确定位。在枢轴支架轴承的组装状态下，内轴承壳相对于枢转元件的提升在任何情况下都被排除。通过铆钉、特别是钢铆钉防止了内轴承壳相对于枢转元件沿切线方向的任何移位。
在内轴承壳具有一个边沿或两个边沿的实施方式中，内轴承壳在组装期间所需的弹性变形也是可能的。枢轴支架轴承的滚动体、特别是滚针或滚子优选地在保持器中被引导。就滚动体组和保持器与枢转元件的枢转运动的同步而言，可以应用原则上已知的多种同步方法。在该方面，例如参照公布DE 10 2009 013 094 B4和DE 34 42 391 C1。
除了内轴承壳之外，枢轴支架轴承通常具有插入到壳体中的外轴承壳。原则上，还可以使滚动体直接在壳体的表面上滚动。外轴承壳也可以通过铆接或其他方式附接至壳体。
待插入铆钉的内轴承壳中的孔优选地在内轴承壳的未硬化状态下制成。在已经制造出孔之后，可以对内轴承壳进行硬化和研磨。只有那时，才将铆钉插入到内轴承壳中，从而在铆钉与轴承壳之间形成刚性连接，该刚性连接可以在不破坏的情况下不再松开。与铆钉和内轴承壳之间的连接相反，铆钉与枢转元件之间的连接是可拆卸的，如结合铆钉足部的几何形状所描述的。可以手动或自动地将铆钉应用至内轴承壳。
附图说明
下面借助于附图更详细地对本发明的若干示例性实施方式进行说明。在附图中：
图1和图2示出了枢轴支架轴承的第一示例性实施方式的剖视图；
图3示出了另一枢轴支架轴承的截面；
图4示出了根据图3的布置的各个部件；
图5示出了根据图4的布置的细节图；
图6以另一视图示出了根据图4的布置。
具体实施方式
除非另有说明，否则以下说明均涉及两个示例性实施方式。在所有图中，彼此对应或具有基本相同作用的部件用相同的附图标记表示。
整体上用附图标记1标识的枢轴支架轴承包括枢转元件2，该枢转元件安装成借助于滚动体4、即滚针或柱形滚子在壳体3中枢转。枢轴支架轴承1安装在液压轴向活塞泵或轴向活塞马达中。通过改变枢转元件2相对于壳体3的角位置，可以以本身已知的方式改变液压泵或液压马达的输送量。还被称为枢轴支架的枢转元件2的枢转轴线用SW表示。
用于滚动体4的内滚动表面5由保持在枢转元件2上的内轴承壳7提供。用6表示的相关联的外滚动表面由插入到壳体3中的外轴承壳8提供。在示例性实施方式中，两个轴承壳7、8具有均匀的壁厚W。内滚动表面5的半径由R1表示，外滚动表面6的半径由R2表示。
滚动体4在保持器9中被引导。保持器杆由11表示。滚动表面5、6沿周向方向延伸了角度α，该角度α大于保持器9延伸的由β表示的角度。
铆钉10位于具有弯曲带状件的总体基本形状的内轴承壳7的每个端部附近，并且用于将内轴承壳保持在枢转元件2上，使得内轴承壳不能沿轴承壳7的周向方向、即不能沿枢转方向移位。
铆钉10为钢铆钉，每个铆钉具有用13表示的筒形铆钉足部。铆钉足部13接合在枢转元件2中的盲孔12中，该盲孔也是筒形的并且通常被称为凹部。
在内轴承壳7附接至枢转元件2之前，两个铆钉10牢固地连接、即铆接至内轴承壳7。为此，内轴承壳7具有两个孔14，这两个孔在内轴承壳7的未硬化状态下已经形成。每个孔14具有筒形部分15，该筒形部分在外侧被锥形部分16连接。锥形部分16设计成接纳铆钉10的埋头头部17。在将铆钉10插入到孔14中同时使埋头头部17变形之前，对内环元件7进行热处理、即硬化和研磨。
包括内轴承壳7和两个铆钉10的组件在枢轴支架轴承1配装至枢转元件2时弹性向上弯曲，直到铆钉足部13卡入凹部12中为止。以类似的方式，所述组件从枢转元件2的后续移除也将是可能的。由于内轴承壳7的曲率，内轴承壳借助于铆钉10足够紧地保持在枢转元件2上以用于组装目的并且还用于轴向活塞机的后续操作。在这种情况下，铆钉足部13与枢转元件2之间不存在铆钉连接。
在根据图1和图2的示例性实施方式中，内轴承壳7具有两个边沿18。在这种情况下，外轴承壳8的两个边沿19定形状成使得这两个边沿部分地包围内轴承壳7，使得由轴承壳7、8形成捕获单元。在图2所示的布置中，滚动体4在铆钉10上是直接可见的。实际上，在优选实施方式中，避免了铆钉10被滚动体4滚过。
同样在根据图3至图6的示例性实施方式中，内轴承壳7的布置有铆钉10的部分优选地不用于被滚动体4滚过。与根据图1和图2的示例性实施方式相比，根据图3至图6的示例性实施方式中的内轴承壳7仅具有单个边沿18，其中，在滚动表面5与边沿18之间设置有具有过渡半径的槽形凹部。在这两个示例性实施方式中，在枢轴支架轴承1的操作期间保持器9的运动通过未示出且本身已知的方式与枢转元件2的枢转运动同步。
