Abstract

在按照现有技术将一个部件压配合地装在一个轴上时,在安装完的部件中保留有可能损坏部件的应力。按照本发明的电枢(15)具有一个待安装到轴(10)上的部件(1),它具有内径缩细部(7),该缩细部啮合到轴(10)上的滚花(11)内,在这里,随着时间的推移,最初的应力至少可以部分地减小。

Description

用于电机的电枢
现有技术
本发明涉及按照权利要求1所述类型的用于电机的电枢。
由US-PS4,886,392已经公开了具有一个轴的转子，这个轴在轴的表面上具有一个滚花结构和一些光滑区域，在这里，轴在滚花区域和光滑区域中具有大约相同的外径。然而，推置到轴上的转子没有设置在滚花区域内的内径缩小结构。
从US-PS5,625,511中已经知道了具有一个其中心设有滚花结构的轴的定子。在轴上滚花结构的那一面有一个光滑区域，它具有与滚花结构一样的外径并且可以用于固定在轴上的定子导向。然而定子没有设置在滚花结构区域内的内径缩小。
从慕尼黑Carl Hanser出版社出版的S.Hidebrandt博士教授的“精密机械部件”一书221页中知道了使用具有滚花的轴，在这里，滚花具有比在滚花区域内推置到轴上并且在那里固定的部件内径大的外径。所述部件在机械上比所述轴软并且压入轴的滚花里，结果是获得形状吻合的支持。滚花之外的轴外径比部件内径小。
US-PS4,339,873示出了一个转子轴，它具有一个凹槽，滚花配置在凹槽内。推置到转子轴上的部件在安装状态以其缩细部分安置在滚花区域内。然而，这个缩细是在部件推置到轴上之后由于部件塑性变形而产生的。
本发明优点
相比而言，具有权利要求1所述特征的本发明电枢的优点是，可以采用简单的方式方法将一个部件固定到一个轴上并且可靠地固定。另外，由于部件内径上的缩细部会使部件材料在缩细部区域内塑性变形和流入滚花内并且这样构成形状吻合连接。
采用有利的方式可以使用一个喷塑的磁铁用作这个部件，因为它在机械上比所述轴软。
另外有利的是，缩细部设置在部件中心，因为通过此可以使应力围绕着滚花结构均匀地减小。
附图
附图中简单地示出了本发明的一个实施例，并且在下面的说明中进行了详细说明。图中示出：
图1为用于本发明电枢的一个部件，
图2a、b和c示出了一个轴如何用于本发明的电枢和如何被制造，
图3为在组装状态下的本发明电枢。
实施例说明
图1示出了一个部件1，这个部件例如是一个机械式球轴承或者是一个注塑的磁铁，与轴10相比(图2)由相对更软的材料制成。
部件1具有一个中心轴线3，它例如也可以是对称轴线，并且具有一个在轴向方向在部件1内部延伸的槽4。在部件1的槽4里，在轴向方向例如在中间设置了一个缩细部7，也就是说，部件1在槽4的靠外区域内具有一个内径Di，而在缩细部7区域内具有一个较小的内径di。
图2c示出了按照本发明电枢的具有一个外径d’a的轴10。
轴10例如被如下制造。在具有一个外径Da的轴10中，在以后滚花11的区域13内进行切槽，它然后具有一个更小的外径da(图2a)。在这个区域内加工上滚花11，如在图2b中所示出的那样。滚花11具有一个外径d’a。滚花种类可以是任意的。它可以由纵槽、横槽或者十字槽组成。
在滚花11之外的轴10的外径Da如果需要的话被这样磨削或者车削，使它与滚花11的外径相同，也就是说，轴10具有一个不变的外径d’a。必要时，外径大于直径Da的滚花11变径到Da。
轴10也可以分段淬火。
图3示出了部件1怎样固定到轴10上。部件1具有一个比滚花11长的轴向长度。
部件1的内径Di例如大约等于图2c中轴10的外径d’a，也就是说，在部件1最初套到轴10上时，部件1由轴10导向。也可以有轻微的压配合。如果部件1继续向轴10上推动，则会在部件1内出现或者提高应力，因为缩细部7被移到滚花11之外的轴10上。如果部件1继续在轴10上推动，一直到缩细部7安置到滚花11的区域内，则部件1由于压配合在缩细部7的区域内变形，因为部件1的材料挤入滚花11的凹槽里。
如果在滚花11周围的区域内部件1由轴10穿过(fuehren)，则在滚花11的边棱(Kanten)上没有出现缺口应力，而是示出了在图3中示出的应力曲线，它示出了向两个轴向方向上围绕着滚花11在部件1中的应力均匀下降。随着时间的推移，甚至在以前的缩细部7的区域内会出现无应力状态，并且部件1只是通过形状吻合连接固定在轴10上。
这样的电枢15可以用于电机或者发电机并且还具有一个没有示出的用于至少一个线圈或者永久磁铁和例如一个换向器的支承体。
