Description

滚动轴承单元和安装方法
技术领域
本发明涉及一种按照权利要求1前序部分所述的滚动轴承单元。
背景技术
已知一种车轮轴承单元，其具有外环和两个内环。
发明内容
本发明要解决的技术问题尤其在于，以高效的构造方式提供这种滚动轴承单元。按照本发明，上述技术问题通过权利要求1的特征解决，由从属权利要求得到本发明的有利设计方案和改进设计。
本发明的基础是一种滚动轴承单元，尤其圆锥滚子轴承单元，其具有至少一个第一内环和至少一个外环。
按照本发明建议的是，滚动轴承单元具有至少一个布置在所述外环的轴向端部区域上的结构单元，该结构单元防止第一内环从外环的布置在轴向端部区域上的开口掉出。以此可以实现高效的构造方式。尤其可以以节省重量的方式实现第一内环防丢失的固定。
优选的是，结构单元参照从结构单元出发远离外环的轴向将内环形状配合地固定在外环上。由此可以尤其在双列圆锥滚子轴承的情况中实现很小的重量。
有利的是，滚动轴承单元具有第二内环，其中，滚动轴承单元不具有将第二内环的面向第一内环的轴向端部固定在第一内环的面向第二内环的轴向端部上的部件。以此可以实现将内环相互固定的部件的很小的重量。尤其可以省掉将两个内环在它们的径向内表面上相互固定的金属环。
在本发明的改进设计方案中，所述结构单元具有至少一个弹性体元件，该弹性体元件相对滚动轴承单元的旋转轴线具有的最大距离小于外环的滚道相对所述旋转轴线的最大距离，并且优选小于滚动轴承单元的滚动体的端侧的凹部相对所述旋转轴线的最大距离。所述旋转轴线是在滚动轴承工作运行时外环和第一内环相对彼此转动的轴线。物体相对所述旋转轴线的最大距离是该物体的各个点相对于旋转轴线的距离中的最大值。由此可以实现密封装置的特别紧凑的结构，该密封装置是所述结构单元的一部分。
优选的是，所述结构单元的(使得第一内环相对于确定的方向形状配合地固定在外环上的元件)同时是内环与外环之间的间隙的唯一的密封装置。以此可以实现结构上简单的构造。
有利的是，结构单元不具有弹性体构成的元件。以此可以节省构件。
此外建议的是，所述滚动轴承单元具有至少一个第二结构单元，所述第二结构单元与所述第一结构单元轴向向对地布置并且将滚动轴承单元的第二内环形状配合地固定在外环上。以此可以在滚动轴承单元的轴向端部上布置相同构造的部件，这导致低成本的构造。
此外建议一种车轮轴承，尤其用于载重货车的车轮轴承，所述车轮轴承具有如上所述的滚动轴承单元。
此外建议一种用于安装尤其如上所述的滚动轴承单元的安装方法，其中，内环至少部分地被带入外环中并且所述内环相对于至少一个轴向通过布置在滚动轴承单元的轴向端部上的结构单元固定在外环上。以此可以实现高的效率。
附图说明
其他优点从下面的附图说明得出。在附图中示出本发明的实施例。附图、说明书和权利要求包含很多特征组合。本领域技术人员适宜地也可以单个地考虑这些特征并且组合成合理的其他组合。
图1示出剖切按照本发明的滚动轴承单元的轴向剖面的立体视图，
图2示出剖切滚动轴承单元的轴向剖面的上半部分，
图3示出图2的放大图。
具体实施方式
图1示出剖切按照本发明的滚动轴承单元的轴向剖面的立体视图，所述滚动轴承单元具有第一内环10和外环12。滚动轴承单元的结构单元14布置在外环12的轴向端部区域上并且固定在外环12上。轴向地与内环10相邻地布置有滚动轴承单元的另外的内环20，另外的内环20具有用于滚动体列的滚道，在内环20相对于外环12转动时所述滚动体列在内环20上和外环12的滚道上滚动。外环具有另外的滚道30，在内环10相对于外环12转动时第二组滚动体在另外的滚道30上滚动，其中，第二组滚动体在此当然也在内环10上滚动。外环12是一体式构造的。该滚动轴承单元是车轮轴承并且构造成双列圆锥滚子轴承单元。由于构造成圆锥滚子轴承单元，所以内环10不能向另外的内环20的方向从外环掉出。结构单元14防止内环10从外环的布置在轴向端部区域上的开口16掉出。为此，结构单元14具有环形的区域44，环形的区域44径向向内突伸并且贴靠在内环10的端侧的区域46上，并且以此形状配合地保护内环10以不会沿远离另外的内环20延伸的轴向18掉出，并且防止沿远离另外的内环20延伸的轴向18掉出(图1至图3)。
另外的内环20的轴向端部18贴靠在内环10的轴向端部50上。两个端部48、50相互面对。滚动轴承单元不具有将端部48固定在端部50上的部件。例如没有这样的金属环，所述金属环贴靠在端部48、50上并且例如从后方咬合两个内环20、10的可以布置在内环的径向内侧上的凹槽并且以此将内环形状配合地相互固定。
结构单元14由盖帽元件58和密封单元52构成，密封单元52压到盖帽元件58中。盖帽元件58具有区域44。此外，盖帽元件实现将结构单元14形状配合地固定在外环12上。为此，有凸出部咬合到外环12的槽中，所述凸出部沿径向向外延伸并且是盖帽元件的一部分。密封单元具有板片元件54，板片元件54压入盖帽元件中并且构成用于密封单元52的弹性体元件22的支架。密封单元还包括弹簧元件56，弹簧元件56构造成螺旋弹簧并且将弹性体元件22的密封唇边压紧内环10。弹性体元件22的另外的密封唇边同时径向向内和轴向向内突伸，其中，该密封唇边不贴靠在内环上。
弹性体元件22具有相对滚动轴承单元的旋转轴线24的最大距离26，该最大距离26小于外环的滚道30相对旋转轴线的最大距离28(图2)。此外，距离26小于滚动轴承单元的布置在内环10和外环12之间的滚动体34的端侧的凹部32的最大距离。
此外，滚动轴承单元包括元件36，元件36与盖帽元件58结构相同，并且构成第二结构单元40。元件36与盖帽元件58相似地形状配合地固定在外环12上并且将内环20形状配合地固定在外环12上，确切而言同样以与盖帽元件58将内环10固定在外环12上相似的方式。元件36防止内环20沿与方向18相反指向的方向从外环12移出或者说沿与方向18相反指向的方向掉出。然而没有与密封单元52类似的密封单元被压入元件36中。元件36和尤其贴靠在内环20的端侧上的环形的区域60构成唯一的密封装置，该密封装置将内环20和外环12之间的间隙38密封。
滚动轴承单元可以是载重货车的车轮轴承。
在安装滚动轴承单元时，内环10部分地带入外环12中并且通过安置在结构单元14上，即尤其通过盖帽元件58的凸出部固定在外环12的凹槽中，内环10固定在外环12上，确切而言相对于轴向18固定。
在端侧，盖帽元件58具有多个凹部，该凹部延轴向延伸并且沿周向相互间隔开。以此不仅节省材料也节省了重量。
