Description
<Desc/Clms Page number 1>
Die Erfindung bezieht sich auf Ständer für elektrische Maschinen, mit einem aus Blechen geschichteten Kern, der mittels zweier, je an einer Ständerstirnseite angeordneter Druckplatten aus magnetisierbarem Stahl zusammengehalten ist, die mit in Achsrichtung offenen, im wesentlichen radial verlaufenden Nuten und mit in diesen befestigten Druckfingern aus unmagnetisierbarem Stahl versehen sind.
Ziel der Erfindung ist ein Ständer dieses Aufbaues, bei dem die zu der Ständerstirnseite senkrechte Abmessung der aus jeweils einer Druckplatte und den an ihr befestigten Druckfingern bestehenden Einheiten die
EMI1.1
herstellbar sind.
Zur Erreichung dieses Zieles sind erfindungsgemäss die Nuten als durchgehende Schlitze ausgebildet und die in je einen Schlitz eingesetzten, stabförmigen Druckfinger an die Druckplatte im Bereich des Schlitzes angeschweisst. Die Herstellung von Schlitzen ist einfacher als die von Nuten, bei welchen darauf geachtet werden muss, dass sämtliche Nutensohlen in einer gemeinsamen Ebene liegen. Bei Druckplatten mit Schlitzen und in
EMI1.2
manchen Maschinen um 100 bis 120 mm ; was zu einer merklichen Verringerung des Kupfergewichtes und der Kupferverluste führt, die nicht mit Nachteilen verbunden ist.
Die Erfindung ist im folgenden an Hand einer beispielsweisen Ausführungsform näher erläutert, die in den Zeichnungen veranschaulicht ist. In den Zeichnungen zeigt Fig. 1 einen Teil eines erfindungsgemässen Ständers in
EMI1.3
Druckeinrichtungen sind die Ständerbleche aneinandergepresst. Diese Druckeinrichtungen, die an den beiden Stirnseiten des Ständers angeordnet sind, bestehen je aus einer Druckplatte --5-- und aus an dieser befestigten Druckfingern--6--. In den aus üblichem magnetisierbarem Stahl hergestellten Druckplatten sind in bezug auf die Ständerachse radiale Schlitze --7-- ausgebildet, und in jedem Schlitz ist ein Druckfinger --6-- aus unmagnetisierbarem Stahl eingesetzt. Platten und Finger sind im Bereich des Schlitzes miteinander verschweisst.
An den beiden Ständerstirnseiten einander gegenüberliegender Druckplatten sind mittels Gewindestangen--8-und Muttern--9--zusammengespannt. In den Druckplatten sind ferner Gewindebohrungen vorgesehen, in die Justierschrauben --9-- eingeschraubt sind. Diese gegen einen festen Teil des Ständer-oder Maschinengestelles abstützbaren Schrauben ermöglichen eine Ausrichtung der Druckplatten gegenüber dem Kern.
Die einzelnen Druckfinger sind in denselben Abständen ausgeteilt wie die Zähne des Kernes, von welchen
EMI1.4
und untereinander gleichen Druckfinger dient unmagnetisierbarer Flachstahl, der einfach zerschnitten wird. Die üblichen Toleranzen und die Oberflächenbeschaffenheit der stabförmigen Abschnitte erlauben deren Verwendung als Druckfinger ohne irgendwelche Bearbeitung. Auch die saubere Durchführung der notwendigen Schweissverbindungen stösst auf keine Schwierigkeiten. Von dem Abstand der Druckplatten von dem zusammengepressten Eisenkern hängt die Erwärmung der Platten ab. Dieser Abstand ist davon bestimmt, wie weit die Schmalseiten der hochkant gestellten Druckfingerstäbe über die Plattenseite vorstehen, die dem Kern
EMI1.5
schmal sein können, so dass der Verbrauch von teurem unmagnetisierbarem Stahl weitestgehend herabgesetzt ist.
Aus diesem Grund und vor allem wegen des geringen Arbeitsaufwandes bei ihrer Herstellung erweisen sich erfindungsgemässe Ständer als sehr wirtschaftlich.

The invention relates to stator for electrical machines, with a core layered from sheet metal, which is held together by means of two pressure plates made of magnetizable steel, each arranged on a stator end face, with essentially radial grooves that are open in the axial direction and with pressure fingers fastened in them are made of non-magnetizable steel.
The aim of the invention is a stand of this structure, in which the dimension perpendicular to the stand face of the units consisting of a pressure plate and the pressure fingers attached to it
EMI1.1
can be produced.
To achieve this goal, according to the invention, the grooves are designed as continuous slots and the rod-shaped pressure fingers inserted into each slot are welded to the pressure plate in the area of the slot. The production of slots is easier than that of grooves, in which it must be ensured that all the groove bottoms are in a common plane. For printing plates with slots and in
EMI1.2
some machines by 100 to 120 mm; which leads to a noticeable reduction in the copper weight and the copper losses, which are not associated with disadvantages.
The invention is explained in more detail below using an exemplary embodiment which is illustrated in the drawings. In the drawings, FIG. 1 shows part of a stand according to the invention in FIG
EMI1.3
The stator plates are pressed together with pressure devices. These pressure devices, which are arranged on the two end faces of the stand, each consist of a pressure plate --5-- and pressure fingers - 6-- attached to it. In the pressure plates made of conventional magnetizable steel, radial slots --7-- are formed in relation to the stator axis, and a pressure finger --6-- made of non-magnetizable steel is inserted in each slot. The plates and fingers are welded together in the area of the slot.
On the two stand end faces of opposite pressure plates are clamped together by means of threaded rods - 8 - and nuts - 9. There are also threaded holes in the pressure plates, into which adjusting screws --9-- are screwed. These screws, which can be supported against a fixed part of the stand or machine frame, enable the pressure plates to be aligned with respect to the core.
The individual pressure fingers are distributed at the same intervals as the teeth of the core, from which
EMI1.4
and the same pressure finger is used for non-magnetizable flat steel that is simply cut up. The usual tolerances and the surface properties of the rod-shaped sections allow them to be used as pressure fingers without any processing. Even the clean execution of the necessary welded connections does not encounter any difficulties. The heating of the plates depends on the distance between the pressure plates and the pressed iron core. This distance is determined by how far the narrow sides of the pressure finger rods placed on edge protrude beyond the side of the plate, which is the core
EMI1.5
can be narrow, so that the consumption of expensive, non-magnetizable steel is largely reduced.
For this reason, and above all because of the low amount of work involved in their manufacture, stands according to the invention have proven to be very economical.
