Abstract

在用于汽车供油的G-转子泵中,在外转子(14)内设置多个切口(19)。可以将燃料的污垢颗粒收集在切口(19)内。由此,可以使外转子(14)和内转子(9)的相互滚动区域的磨损保持特别小。

Description

G-转子泵
技术领域
本发明涉及特别是用作汽车供油泵的G-转子泵,它有一外转子和一可相对外转子运动的内转子,其中,在外转子和内转子之间限定出一供油室。
背景技术
这种G-转子泵通常也称为齿轮泵或者偏心泵并在实际应用中公开了。在这种实际已知的转子泵中,外转子具有内齿,内转子具有对应于内齿的外齿。外齿比内齿少一个齿,由此构成供油室。当内转子或者外转子传动时,内转子的外齿在外转子的内齿上滚动。供油泵用G-转子泵中的常见问题是:污垢颗粒进入转子之间,导致其磨损并因此降低了G-转子泵的使用寿命。因此,G-转子泵大都预接一个网眼特别细的过滤器。然而,由于污垢颗粒会很快堵塞过滤器,所以这种构造导致G-转子泵维护费用很高。
这种已知的G-转子泵的缺陷是,它对油流中的污垢颗粒非常敏感。
发明内容
依据本发明,这一问题可由此得以解决,即在外转子和/或内转子内设置多个切口。
通过这种构造,可以将污垢颗粒收集在切口内并因而不会到达转子的相互间滚动的齿面。随后,污垢颗粒从切口中被洗掉,或者切口长能时间地收集污垢颗粒。在这种情况,切口需要至少有与在油流中的污垢颗粒的数量相应的尺寸。本发明的G-转子泵由此在所供液体很脏的情况下仍然具有特别长的使用寿命。因此,G-转子泵不再需要网眼特别细的过滤器。因此,依据本发明的G-转子泵特别适合供油泵使用。
依据本发明的另一个有利的改进方案,若切口为设置在外转子齿根内的凹槽,则污垢颗粒通过油流会聚在切口里并可以留在那里。
依据本发明的另一个有利的改进方案,若切口为设置在内转子齿根内的凹槽,则污垢颗粒在离心力作用下易于从切口中甩出。
若将切口设置在外转子的全部齿根内或者内转子的全部齿根内,依据本发明的G-转子泵具有很强的污垢颗粒接受能力。
依据本发明的另一个有利的改进方案,若切口在外转子和/或内转子的整个高度上延伸,则内转子和外转子的边缘的磨损极小。
依据本发明的另一个有利的改进方案,若切口为槽形,则加工特别简便。
切口底部可呈锐角形或者角形。依据本发明的另一个有利的改进方案,若切口在其底部区域里有一半径,则可使污垢收集变得简单并有助于排出污垢颗粒。在这种情况下,切口的缺口应力集中同样极小。
若外转子和/或内转子由金属制成,有助于进一步延长本发明的G-转子泵的使用寿命。
若外转子和/或内转子由塑料制成,则有助于降低本发明的G-转子泵的制造成本。
在另一个改进方案中,根据切口的设置,底部和顶部可以由塑料和/或金属烧结体制成。
附图说明
本发明可以有很多实施方式。为进一步说明其基本原理,下面借助附图对其中两个实施方式进行说明。其中:
图1为带有依据本发明所述G-转子泵的供油单元纵剖面;
图2为沿图1的II-II线段G-转子泵的剖面放大图;
图3为另一实施方式的G-转子泵的剖面图。
具体实施方式
图1示出一供油单元1,它有一用于容纳电动机4和G-转子泵2的外壳3。G-转子泵2具有底部5和与底部5通过隔离架6保持规定距离的顶盖7。隔离架6和顶盖7在此是一体制成的。在顶盖7和底部5之间,布置一固定在电动机4的轴8上的内转子9。轴8具有平面10和凸台11,以便带动内转子9运动。内转子9由此只能在图中所示的位置上与轴8连接。内转子9具有图2所示的外齿12,所述外齿与外转子14的内齿13啮合。
顶盖7和底部5分别具有G-转子泵2的进口15和出口16。燃料由此通过顶盖7吸入并轴向流过G-转子泵2。供油单元1的外壳3具有连接管17,它用于连接图中未示出的管路。为清楚说明起见,在附图中,燃料流向用箭头标示。
图2示出沿图1的II-II线的G-转子泵2的剖面放大图。为简化附图,没有示出G-转子泵2的外壳3和隔离架6。内转子9的外齿12比外转子14的内齿少一个齿。由此形成供油室18,要供给的液体从图1所示的进口15输送到出口16。在图2中,用箭头表示内转子9和外转子14的转向。在外转子14的内齿13的齿根内,设有沿外转子14的整个高度延伸的切口19。在该切口19内收集在所供液体中的污垢颗粒,由此防止污垢颗粒在内齿13和外齿12的齿面上相互摩擦。
图3示出根据另一实施方式的G-转子泵的剖面图,如图2一样,G-转子泵具有带外齿21的内转子20和带内齿23的外转子22。这个实施方式与图2的区别在于,用于收集污垢颗粒的切口24设置在内转子20的外齿21的齿根内。而外转子22的内齿23的齿根是光滑的。通过这种结构,在供给液体时,污垢颗粒被收入内转子20的切口24内并通过离心力重新甩出。
