Description

Anordnung zur winkelrechten Befestigung eines Ständerblechpaketes an dem tragenden Gehäuseteil Der Erfindung liegt die Aufgabe zugrunde, ein einfaches, aber sicheres Mittel zu finden, das es ermöglicht, das Ständerblechpaket eines Elektromotors ohne Zentrierung möglichst genau winkelrecht auf dein tragenden Gehäuseteil, z. B. einem Lagerschild, zu befestigen, so daß die Achse des Ständerblechpaketes bzw. dessen Bohrung mit der Achse des in dem Gehäuseteil. also insbesondere einem Lagerschild, gelagerten Läufers genau fluchtet. Dadurch soll die Möglichkeit geschaffen werden. einen sehr kleinen Luftspalt genau einzuhalten, was z. B. bei nur einseitig gelagerten Anbaumotoren für Kühlschränke u. dgl. von großer Wichtigkeit ist.Arrangement for angled fastening of a stator core on the supporting housing part The invention is based on the object of providing a simple, but to find sure means that makes it possible to use the stator core of an electric motor without centering as precisely as possible at right angles to your supporting housing part, e.g. B. a bearing plate, so that the axis of the stator core or its bore with the axis of the in the housing part. so in particular a bearing plate, mounted rotor is exactly aligned. This is to create the possibility. to adhere to a very small air gap exactly what z. B. with only one-sided Attachment motors for refrigerators and the like is of great importance.

Man hat bereits vorgeschlagen, an dem Ständerblechpaket besondere Vorsprünge anzubringen. die aus den Endblechen herausgedrückt werden können, und auf ihrer Oberfläche so zu bearbeiten, daß hierdurch bei der Befestigung des Ständerblechpaketes an dem tragenden Gehäuseteil eine zur Achse des Gehäuseteiles bzw. des Blechpaketes genaue winkelrechte Lage gewährleistet ist. So hat man z. B. das Endblech mit einem Rand versehen, dessen Stirnfläche nach dem Annieten an das Blechpaket planparallel bearbeitet wird. Diese Ausführung ist in der Fertigteig verhältnismäßig umständlich und teuer, und es besteht außerdem die Möglichkeit, daß sich in manchen Fällen der Rand an den zwischen den das Blechpaket zusammenhaltenden Bolzen gelegenen Stellen etwas aufwerfen kann, so daß hierdurch bei der Befestigung des Ständerblechpaketes an dem Lagerungsmittel sich gewisse Ungenauigkeiten ergeben, welche leicht störend wirken können. Die vorliegende Erfindung zeigt nun eine demgegenüber verbesserte Anordnung zur winkelrechten Befestigung eines Ständerblechpaketes.It has already been suggested that the stator core be special To attach projections. which can be pushed out of the end plates, and to process on their surface so that this results in the attachment of the stator core on the supporting housing part one to the axis of the housing part or the laminated core exact angular position is guaranteed. So one has z. B. the end plate with a Provided the edge, the end face of which is plane-parallel after riveting to the laminated core is processed. This version is relatively cumbersome in the ready-made dough and expensive, and there is also a possibility that the Edge at the points located between the bolts holding the laminated core together can raise something, so that this results in the attachment of the stator core there are certain inaccuracies in the bearing means, which are easily disruptive can work. The present invention now shows an improved one Arrangement for angled fastening of a stator core.

Bei der erfindungsgemäßen Anordnung sind die Vorsprünge auf dem Endblech so ausgebildet, daß sie aus die Löcher für die Befestigungsbolzen des Paketes ringförmig umgebenden, aus dem Endblech herausgedrückten Warzen bestehen. Die Fertigung solcher Endbleche ist besonders einfach und billig, und die Bearbeitung der Warzenoberflächen erfordert nur sehr wenig spanabhebende Arbeit. Außerdem wird dadurch, daß nur die verhältnismäßig kleinen Warzen auf dem Lagermittel aufliegen, ein sicherer winkelrechter Sitz gewährleistet.In the arrangement according to the invention, the projections are on the end plate designed so that they are annular from the holes for the fastening bolts of the package surrounding warts that are pressed out of the end plate. The manufacture of such End plates is particularly simple and cheap, and the machining of the wart surfaces requires very little machining. In addition, the fact that only the relatively small warts rest on the bearing means, a more secure right angle Seat guaranteed.

Die Fig. 1 und 2 der Zeichnung zeigen im Grund-und Aufriß ein Ständerblechpaket, das ein Ausführungsbeispiel einer solchen Anordnung zu seiner winkelrechten Befestigung erkennen läßt. 1 ist das Ständerblechpaket eines z. B. zum Antrieb eines Kältekompressors dienenden Elektromotors, das mit seinen beiden Endblechen 2 und 3 durch Schweißraupen 4, 5, 6 und 7 zu einem starren Körper verbunden ist. Diese Schweißraupen sind - wie aus der Fig. 1 ersichtlich ist - an den vier abgestumpften Ecken des einen quadratischen Grundriß besitzenden Blechpaketes angebracht. Jede der vier Ecken des Blechpaketes ist mit einer Bohrung 8 versehen, durch die ein Schraubbolzen 9 hindurchgesteckt ist. Durch die Bolzen 9 ist das Blechpaket einseitig mit dem Lagerschild 10 fest verbunden, in dem der hier der Einfachheit halber fortgelassene Läufer gelagert ist. Das dem Lagerschild 10 anliegende Endblech 3 des Ständerpaketes ist nun mit aus ihm herausgedrückten Warzen 11 versehen, deren jede ein Loch 8 für den Befestigungsbolzen 9 ringsförmig umgibt. Vor der Befestigung des Blechpaketes 1 an dem Lagerschild 10 ist die Oberfläche der warzenförmigen Vorsprünge z. B. durch Abdrehen so bearbeitet, daß die bearbeiteten Flächen in einer zur Paketachse senkrechten Ebene liegen.Figs. 1 and 2 of the drawing show in plan and elevation a stator core, this is an embodiment of such an arrangement for its angled mounting reveals. 1 is the stator core of a z. B. to drive a refrigeration compressor Serving electric motor, which with its two end plates 2 and 3 by welding beads 4, 5, 6 and 7 is connected to form a rigid body. These weld beads are - as can be seen from Fig. 1 - at the four truncated corners of a square Sheet metal package attached to the floor plan. Each of the four corners of the laminated core is provided with a bore 8 through which a screw bolt 9 is inserted is. The laminated core is fixed to the end shield 10 on one side by the bolts 9 connected, in which the runner, left out here for the sake of simplicity, is stored is. The end plate 3 of the stator assembly resting on the end plate 10 is now with lugs 11 pressed out of it, each of which has a hole 8 for the fastening bolt 9 surrounds in a ring. Before attaching the laminated core 1 to the end shield 10 is the surface of the wart-shaped projections e.g. B. machined by turning so that that the machined surfaces lie in a plane perpendicular to the package axis.

Auf diese Weise wird erreicht, daß bei der Befestigung des Ständerblechpaketes an dem Lagerschild der erforderliche sehr kleine Luftspalt ohne weitere Maßnahmen genau eingestellt ist.In this way it is achieved that when attaching the stator core the required very small air gap on the end shield without further measures is precisely set.
