Description

带有多件式保持架的滚动轴承
技术领域
本发明涉及一种带有保持架的滚动轴承、尤其是滚子轴承/滚针轴承，保持架具有至少一个内部保持架和至少一个外部支承保持架，所述内部保持架和外部支承保持架具有与滚动体相配适的窗口，该窗口带有将多个窗口相连接的侧向边缘和横梁，滚动体被引入所述窗口中并且防止滚动体掉落。
背景技术
通过同类文献WO2009/127191A1公开了，为保持架配设有完整环形构造的内部支承架和整环形地实施的外部支承保持架，内部支承架和外部支承保持架被成型和构造结合地用于引导和支承滚动轴承。所述环形的保持架在此处被相互固定。
不利的是，由环形内部保持架和环形外部支承保持架组装的保持架如整体材料保持架一样被处理，并且例如不能被任意安装在轴颈上。由于不仅内部保持架而且支承保持架都必须作为闭合的圈而存在，所以其制造也是相对昂贵的。
发明内容
因此，基于已知的现有技术的缺点，本发明所基于的任务是，进一步改进用于滚动轴承的保持架，节省重量，简化制造并且在困难的安装状况下也使装配容易。
根据本发明，该任务在根据权利要求1的前序部分的滚动轴承方面通过如下方式来解决，内部保持架和支承保持架被构造为带槽的内部保持架圈和/或带槽的支承保持架圈，并且这些圈可以在端侧彼此固定。可替选地，本发明的任务也通过如下方式来解决，内部保持架和支承保持架被构造为内部保持架壳件和/或支承保持架壳件，并且壳件可以在端侧彼此固定。
如果内部保持架和支承保持架被构造为带槽的圈，则其应可被更简单地制造并且比完整的圈更便于操作。如果壳件在有利的构型中被构造为半壳件，则四个半壳件形成完整的保持架。然而这还可以被设置为更小的单元、例如四分之一壳件，其在端侧彼此固定，使得例如八个四分之一壳件形成一个完整的壳件，因为四分之一壳件比半壳件更易于制造。通过所说明的内部和支承保持架圈和壳件的构造得到了非常高的灵活性，从而使得保持架可以容易地适应于各种使用条件。
在固定的特别构造中提出了一种夹紧部，其中带槽的内部圈或内部支承壳件、尤其是半壳件相对于带槽的支承保持架圈或支承保持架壳件/半壳件相互在周向方向上相对转动一个窗口地布置。在此，圈或壳件/半壳件具有端部横梁，并且所述端部横梁构建为与其余横梁相比窄其周向长度的一半。因此，得出了以下可能性，即，所述安装在端部窗口中的滚动体保证了半壳件彼此间的连接，并且用作夹持体。由于端侧的横梁窄了一半，所以在其中一个圈端部或其中一个壳件/半壳件上的缩窄的横梁与在另一个圈端部或另一个壳件/半壳件上的缩窄的横梁共同又形成一个横梁，该横梁与横梁的通常的宽度相对应。滚动体于是通过窗口和横梁使圈或壳件/半壳件在夹在一起之后彼此卡锁。圈或壳件/半壳件的端部横梁的宽度也可以比通常的横梁更大。这导致了，最后的横梁必须具有与端部横梁宽度之和相同的宽度。这不仅必须在内部保持架中实现，而且必须在支承保持架中实现。
在本发明的其他扩展方案中提出了，内部保持架圈和支承保持架圈或内部保持架壳件/半壳件和支承保持架壳件/半壳件彼此固定，例如通过焊接、钎焊、卷边和/或类似方式固定。然而，其可以在彼此无直接固定的情况下仅松散地插接。圈或壳件在此有利地由钢板材料通过成型、冲裁/拉长、弯圆或滚圆而有利地制造。
应用于支承保持架圈和支承保持架壳件的材料比应用于内部保持架壳件的材料更厚，用以在外部引导的保持架中实现更好的支撑，并且在小的内部保持架圈或壳件中可以吸收力。当存在轴承滚子的重量在较大保持架的情况下使内圈变形的危险时，内部保持架圈或内部保持架壳件在其材料强度上被选择得更厚。圈和壳件也可以由管段通过利用可延展的塑料芯扩宽来制造，其中，随后对窗口进行冲裁。最后，圈和壳件可以以切削方式来制造。圈或壳件也可以进一步由塑料或铝制成，这导致离心力和重量的降低。内部保持架或支承保持架也可以被涂层，用以降低摩擦并且提高耐磨性。
为了滚动体的更好的引导，圈或壳件的横梁在其与边缘相邻的端部上具有朝向彼此的突起，滚动体可以被可靠地引导进所述突起中。优选地，内部保持架壳件的横梁在中部配备有大致上U形或M形的朝向内部的成型部，从而得到相对于支承保持架的间距，滚动轴承可以以所述间距被更好地保持。在此，较之具有突起的横梁，所述横梁有利地在突起之间被实施得更窄，使得滚动体、尤其是滚子或滚针被良好地对中地引导。支承保持架圈或支承圈壳件可以具有向内拱曲的边缘，用以更好地引导内部保持架圈或内部保持架壳件，使得形成向内拱曲的U形形状。还要指出的是，支承保持架的滑行面（Anlaufflaeche）可以构建得比内圈的滑行面更大。
附图说明
以下参照所附的附图更为详细地阐述了根据本发明构造的滚动轴承的优选实施形式。其中：
图1示出了支承保持架半壳件的透视图；
图1a示出了根据图1的支承半壳件的侧视图；
图2示出了带有安装好的滚动体的内部保持架半壳件的透视图；
图2a示出了根据图2的内部保持架半壳件的侧视图；
图3示出了相互接合的内部保持架半壳件和支承保持架半壳件的透视图，在内部保持架半壳件和支承保持架半壳件中安装了滚动体；
图3a示出了根据图3的组装好的内部保持架半壳件和支承保持架半壳件的侧视图；
图4示出了即将绕轴接合在一起的各两个相互接合的内部保持架半壳件和支承保持架半壳件的透视图；
图4a示出了根据图4的半壳件的侧视图；
图5示出了由四个半壳件所组装的完整保持架的透视图；
图5a示出了根据图5的完整保持架的侧视图；
图5b示出了根据图5的完整保持架的剖面。
具体实施方式
就详细所示而言，在图1至图5b中用1标记内部保持架半壳件，内部保持架半壳件布置在支承保持架半壳件2内。两个半壳件都具有窗口3，窗口3侧向由边缘4限定而彼此间通过横梁5限定。边缘4沿内部保持架半壳件1和支承保持架半壳件2呈半环形地侧向延伸。在横梁5的与边缘4相邻的端部处设置有突起6，突起6使窗口3在其朝着边缘4的角部处变窄。横梁5不仅在内部保持架半壳件1中而且在支承保持架半壳件2中在突起6之间被构建得更窄，其中，在内部保持架半壳件2上的横梁5在突起6之间具有朝向内部的U形变形部7。
此外，从图1至图5b清楚地得知，在半壳件的端部上的端部横梁5a被实施为窄了正常横梁5的按周向长度的一半，使得两个端部横梁5a彼此接合，形成通常横梁5的宽度。壳件/端部横梁5a朝向彼此的端面被平整地实施，因为端部横梁5a在此处不需要具有突起6。
滚动体8安装到通过内部保持架半壳件1和支承保持架半壳件2形成的窗口3的凹部中，滚动体构造为滚子。
尤其如在图4至图5b中所示，在半壳件夹在一起之后，在半壳件的端侧的窗口3中所安装的滚动体8形成半壳件彼此卡锁，使得如在图5至图5b中所示，形成环形保持架，该保持架由四个半壳件组装。
