Description

燃料泵
技术领域
本发明涉及一种燃料泵，包括电机和叶轮，所述电机具有定子、轴、设置在所述轴上的转子，叶轮由轴驱动，其中所述转子被设计成磁转子，所述叶轮可旋转的安置在泵壳体中。
背景技术
此类燃料泵在机动车的燃料储器中使用并因此为公知的。利用燃料泵将燃料从燃料储器中通过进给管路输送至机动车的内燃机。被设计成磁转子的转子可以是以不同方式设计的磁性材料并且与轴连接。将磁性材料作为小颗粒与塑料混合并且借助注塑形成相应的形状，这是已知的。由塑料粘结的磁性材料构成的转子的缺点在于：为建立与注塑材料的稳固的紧密配合，必需预先对轴进行机械加工。为实现形锁合，在轴上加工出滚花或者类似形状的相应结构。然后必需使转子重量平衡。为此要有针对性地去除材料。在这时所产生的磁性颗粒由于会造成积聚和污染，所以是非常有害的，特别是在自动化的生产时。另外已知的是：将磁性材料这样注塑到之前已压装到光轴上的铁芯上，使得磁性材料完全包围铁芯。除了在重量平衡时所产生的磁性颗粒的问题外，另一个缺点在于：在将铁芯压装至轴上时产生降低轴承使用寿命的沟纹。
发明内容
因此本发明的目的在于，提供一种燃料泵，它的转子能够被安全可靠地自动化制造。
该目的通过如下方法得以实现：转子由叠片组构成，在所述叠片组上注塑形成塑料粘合的磁性材料，叠片组在至少一侧上具有与塑料粘合的磁性材料相比较大的轴向长度。
通过使用冲压叠置的叠片组能够使该叠片组被压装到轴上，而不会因此影响轴的轴承使用时间。利用叠片组的比磁性材料更大的轴向长度使得能够在叠片组上进行重量平衡，因此避免影响制造过程的磁性颗粒的产生。由此使自动化的生产简单化。
当叠片组的较大轴向长度在至少一侧上为最大2cm，优选为0.5cm至1cm时，在未过于提高燃料泵的结构长度的情况下实现了用于平衡区域的足够的长度。
在另一方案中，塑料是聚苯硫醚(PPS)。聚苯硫醚(PPS)使磁性材料能够在塑料中均匀的分布并且可以被很好地注塑。
根据其他有利的实施方案，在使用钕铁硼(Neobdymeisenbor)、铁酸盐粉末或者由钕铁硼/铁酸盐构成的混合材料作为磁性材料时，达到在注塑过程中很好的可加工性和很好的磁性特征。
此外，燃料泵的特别低成本的实现方案是：使用在定子的叠片组制造时被剩下的材料用于转子的叠片组的制造。
附图说明
借助一实施例对本发明进一步阐述。附图中：
图1示出燃料泵的示意图；
图2示出在截面图中根据图1所述的转子。
具体实施方式
在图1中示出燃料泵，其包括电机1和叶轮5，电机包括定子2、轴3、设置在所述轴3上的转子4，叶轮由轴3驱动，其中所述转子被设计成磁转子，所述叶轮可旋转地安置在泵壳体6中。在叶轮5旋转时燃料被从燃料储器通过泵入口7抽入并经由在泵壳体6中的泵出口8通过电机1输送至燃料泵的排出口9。燃料从那儿通过进给管路10到达未示出的机动车的内燃机中。
在图2中所示的转子4包括轴3，叠片组11被压装在所述轴上。在叠片组11的一部分上注射成型有带聚苯硫醚连同钕铁硼材料作为塑料粘合的磁性材料12，其中在叠片组的每一侧上都大约有1cm没有被磁性材料12覆盖。这些未覆盖的区域为平衡区域13，在这些区域中对叠片组11进行材料去除来平衡转子4。
