Description

叶片泵
技术领域
本发明涉及一种叶片泵，其包括外转子、内转子和多个叶片，所述多个叶片沿径向可移动地安装于内转子内的基本上径向的狭槽内，并以可枢转方式固定到外转子，其中外转子由导块构成，导块沿定子的内圆周表面滑动并且通过它们的轴向端面在导轨内被导引。
背景技术
从DE 100 40 711 A1中已知一种具有环形内转子的叶片泵，其中多个沿径向向外延伸的叶片元件以能够沿径向移动的方式容纳在所述内转子中。叶片元件的径向内端部搁置在抗扭的中央部件上，且径向外端部搁置在抗扭的外环上。转子能够绕相对于中央部件和外环的中心轴线偏移的旋转轴线旋转。以此方式，当转子在叶片元件之间旋转时，形成输送单元或工作空间，输送单元或工作空间首先扩大然后又缩小。通过改变输送单元的体积，将流体吸入输送单元内并随后排出。叶片元件的端部分别在中央部件和外环上滑动。此种叶片泵结构简单并且制造成本低廉。
为了提高效率，从DE 195 32 703 C1中已知一种摆式滑阀泵形式的叶片机。在这种泵中，叶片元件以可移动方式位于内转子内，然而它们在环形外转子内以可枢转方式受到支撑。内转子的旋转轴线相对于外转子的旋转轴线偏移，使得在操作过程中，形成类似地扩大随后又缩小的传输单元。但从DE 195 32 703 C1中已知的摆式滑阀泵结构复杂，因此制造成本高昂。
发明内容
本发明的任务是提供一种高效、简单同时制造成本低廉的叶片机。
这个任务依据本发明来完成，其中导轨设置在开头所提及的叶片泵内的导环内。
依据本发明的具有带导轨的导环的这种叶片泵构造，具有如下基本的优点：叶片泵基本上构造得较为简单，因为它一方面具有较少的零件，另一方面零件构造得较为简单。因此，也能够较容易地安装。导环用于导引导块，使得导块总是即在叶片泵各个操作情形下置于定子的内圆周表面上，并且实际上与叶片泵的转速无关。因此，该导轨是导块的强制导引，其保证它们永久和流体密封地置于内圆周表面上。
导环的这种强制导引构造具有如下基本优点，即叶片泵的工作空间总是能沿轴向进入，并且不会由控制元件或者导引元件关闭。不需要设置特定的穿孔，这另外会扰乱工作流体的流动。
在本发明的另一改进中，导环在端面侧放置于定子和导块上。因为仅必须将导环夹到导块的轴向端面上，所以使得这种构造的组装可以变得简单。此外，能够将导块安装到定子的内圆周表面，直到例如使用特定的安装工具将导环固定到位
依据本发明，导环具有基本C形的横截面，即带有两个自由区段和沿周向延伸的凹陷——尤其是环形凹槽——的侧向敞开的横截面。因为此种导环不具有底切，且将该环构造成用于前面以及后面——这就表示对于泵的两个端面而言完全相同——所以此种导环能够简单制造并容易安装。
通过对凹槽的精确加工，能够无间隙地容纳定子和导块。此外，导环的两个自由区段沿轴向指向内部。导环具有形成环的外部的平坦基体，该平坦基体例如置于密封盖上。
导环的两个自由区段围绕定子的端面，并且因此限定环相对于定子的位置并因此位于叶片泵的内部。以此方式，定子也固定于泵内的合适位置。
依据优选实施方式，导环的两个自由区段之一，尤其是径向内区段，接合进导块的端面凹陷内。该端面凹陷是形成部分环的凹槽。导环的自由区段插入导块的凹槽内，形成咬合，并保证导块固定安装到定子的内圆周表面上，即使例如在抽吸阶段中工作空间内为真空亦是如此。
在优选实施方式中，导块的端面区域的横截面为C形，也就是说侧向敞开，且两个轴向向外突出的区段构成所述凹陷的侧面。因此，导环和导块都构造为C形并且互相咬合地接合，通过将两个具有凹槽的侧面面对。
优选地，导块的径向内区段置于导环的径向内圆周表面上。以此方式，获得附加导引，使得不仅保证导块不会从定子的内圆周表面脱离，而且在高速时，导块的接触压力的一部分被导环吸收。此外，由于导块和导环的这种构造，在叶片泵沿较大或较小输出效率方向的致动过程中，导块沿着导环由导环有效地携带并导引。这意味着导块不仅沿周向而且也沿径向被导引。
在一特别优选的构造中，导块的径向内区段的轴向端面和导环的轴向外端面位于同一平面上。此外，在本发明的另一改进中，导环的轴向外端面和叶片的轴向端面位于同一平面内。以此方式，对各工作空间而言，都可以由位于导块和导环的两个轴向端面上的盖的平坦表面以简单的方式封闭。此外，通过加工导环、导块的端面和叶片的端面，能够保证流体密闭地设置。
从从属权利要求和下列描述将清楚本发明的其他优点、特点和细节并且将参照附图中的一个特别优选的示例性实施方式更加详细地说明本发明的其他优点、特点和细节。附图中所示的特点以及权利要求和说明书中所描述的特征能够分别地或任意组合地构成本发明的基础。
附图说明
在附图中，
图1示出本发明的叶片泵的侧视图；
图2示出沿图1的线II-II的截面；
图3示出沿图2的线III-III的截面；和
图4是叶片泵的立体视图，其中示出导环的局部内部图。
具体实施方式
为了更好地理解本发明，参照DE 10 2005 048 602的全文内容，其内容在此引入本文作为参考。
图1示出总体标识为10的叶片泵的侧视图，叶片泵10具有由驱动轴14驱动的内转子12。内转子12具有径向狭槽16，叶片18沿径向可移动地安装于各径向狭槽16内。叶片18具有厚的外端20，导块22可枢转地安装于外端20上。可从图3中清楚看到，这个导块22置于定子26的内圆周表面24上。这些导块22形成外转子28，其与内转子12一起沿周向相对于定子26旋转。叶片18、内转子12和导块22，与定子26一起形成工作空间30，当内转子12旋转时，该工作空间的容量扩大又缩小。
能够从图4中推知，导环36设置于定子的端面32和以及导块22的端面34上，在下文对此进行更详细地描述。
可从图2和图4中清楚看到，导环具有C形横截面，由此两个区段38和40彼此相对平行地定向，并沿轴向指向内侧。区段38围绕定子26的位于其径向外部42上的边缘侧面，内区段40接合进位于导块22的端面34上的凹陷46内，凹陷46构造成为凹槽44。这可从图2和图4中清晰看出。以此方式，导块22保持于定子26的内圆周表面24上。因此，导环36具有位于其两个区段38和40之间的导向凹槽48，如前所述，在导向凹槽48内接合进定子26的端面32和导块22的构造为C形的端面34的径向外区段50。其中可枢转地安装有叶片18的自由端的另一区段52，置于导环36的内圆周表面54上。以此方式，产生对导块22沿周向以及沿径向的强制导引。
此外，从图2中清楚看到，导块22的区段52的端面56和导环36的沿轴向外部的前表面58位于共同平面60上。此外，各叶片18的轴向端面62位于这个平面上。最后，内转子12的轴向端面64也位于这个平面上。这使得通过简单地放上一平面盖，即可以简单地方式封闭工作空间30。此外，容易看出，本发明的叶片泵10能够被容易地安装，并且仅由几个部件构成。
