Description

Die Erfindung bezieht sich auf eine Anordnung zum Befestigen haubenähnlicher, ringförmig geschlossener Teile, insbesondere von Lüfterhauben, am Gehäuse eines Elektromotors, die in axialer Richtung mehreren sich radial vom Motorkörper aus erstreckenden Montageböckchen aufgeschoben sind, in denen sich Ausnehmungen zur Aufnahme von das zu befestigende Teil an seinem Umfang radial durchsetzenden Blechschrauben befinden.The invention relates to an arrangement for fastening hood-like, ring-shaped closed ones Parts, in particular of fan covers, on the housing of an electric motor, which several in the axial direction are pushed up radially from the engine body extending mounting brackets, in which there are recesses for receiving the part to be fastened on its circumference radially penetrating self-tapping screws are located.

Bei bekannten Befestigungen dieser Art (DT-PS 8 39 225 sowie DT-Gbm 72 42 257) müssen die Ausnehmungen der Montageböckchen entweder während der im Spritzgußverfahren erfolgenden Herstellung des Motorkörpers durch die Verwendung seitlicher Schieber ausgespart oder nach dem Guß durch nachträgliches Bohren angebracht werden. Beide Möglichkeiten sind mit einem beträchtlichen Bearbeitungsaufwand verbunden, den die Erfindung vermeiden will.With known fastenings of this type (DT-PS 8 39 225 and DT-Gbm 72 42 257) the recesses the mounting bracket either during the injection molding production of the Motor body cut out by using side slides or after the casting by subsequent Drilling to be attached. Both options involve a considerable amount of editing connected, which the invention seeks to avoid.

Als Lösung der gestellten Aufgabe wird bei der eingangs genannten Befestigung erfindungsgemäß vorgeschlagen, daß die Ausnehmungen der Montageböckchen entgegen der Aufschubrichtung des zu befestigenden Teiles axial geöffnet und auf ihrer Öffnungsseite von den Innendurchmesser des zu befestigenden Teiles in seiner Aufschubrichtung stirnseitig anstößt.As a solution to the problem, it is proposed according to the invention for the fastening mentioned at the outset that that the recesses of the mounting brackets counter to the pushing direction of the to be fastened Part opened axially and on its opening side of the inner diameter of the part to be fastened abuts on the front side in its pushing-on direction.

Auf Grund dieser Merkmale ist es möglich, die Ausnehmungen aller Montageböckchen in einer Richtung zu entformen und somit die Verwendung seitlicher Schieber beim Spritzguß bzw. das nachträgliche Anbringen von Bohrungen einzusparen. Infolgedessen wird der Herstellungsaufwand in der angestrebtenDue to these features, it is possible to make the recesses of all mounting brackets in one direction to demold and thus the use of side slides for injection molding or subsequent attachment to save on drilling. As a result, the manufacturing cost is aimed at

Weise verringert.Way reduced.

Ein Ausführungsbeispiel der Erfindung wird ap Hand der Zeichnung näher beschrieben. Es zeigtAn embodiment of the invention is described in more detail ap hand of the drawing. It shows

F i g. 1 die teilweise Seitenansicht eines mit einer entsprechend den beanspruchten Merkmalen befestigten Lüfterhaube ausgestatteten Elektromotors im Halbschnitt, F i g. Fig. 1 is a partial side view of one attached with one according to the claimed features Fan cover equipped electric motor in half section,

F i g. 2 die vergrößert dargestellte Befestigung der Lüfterhaube aus F i g. 1,F i g. 2 shows the enlarged view of the fastening of the fan cover from FIG. 1,

F i g. 3 die Ansicht dieser Befestigung in Richtung des Pfeiles A in F i g. 2 undF i g. 3 shows the view of this attachment in the direction of arrow A in FIG. 2 and

Fig.4 die Ansicht dieser Befestigung in Richtung des Pfeiles Bin F i g. 3 bei abgenommener Lüfterhaube.4 shows the view of this attachment in the direction of the arrow Bin F i g. 3 with the fan cover removed.

Der in F i g. 1 in der teilweisen Seitenansicht im Halbschnitt abgebildete Elektromotor setzt sich aus dem Motorgehäuse 1 mit dem darin angeordneten Stator 2 sowie dem in diesem umlaufenden Rotor 3 zusammen. Die rückwärtige Führung der Rotorwelle 4 übernimmt das mit dem Lager 5 versehene Lagerschild 6, außerhalb dessen der Rotorwelle 4 das Lüfterrad 7 aufgesetzt ist Als Berührungsschutz für das Lüfterrad dient die mit Ansaugöffnungen 8 durchbrochene Lüfterhaube 9.The in F i g. 1 electric motor shown in the partial side view in half section is suspended the motor housing 1 with the stator 2 arranged therein and the rotor 3 rotating in it. The rear guidance of the rotor shaft 4 takes over the bearing plate 6 provided with the bearing 5, outside of which the rotor shaft 4, the fan wheel 7 is placed. As a protection against contact for the fan wheel The fan cover 9, which is perforated with suction openings 8, is used.

Die Befestigung der Lüfterhaube 9 besteht aus sich radial vom Lagerschild 6 aus erstreckenden, den F i g. 2 bis 4 deutlicher zu entnehmenden Montageböckchen 10, denen die Lüfterhaube 9 in axialer Richtung aufgeschoben ist. Diese Montageböckchen 10 besitzen zur Aufnahme der die Lüfterhaube 9 an ihrem Umfang radial durchsetzenden Blechschrauben 11 Ausnehmungen 12, die entgegen der Aufschubrichtung 13 der Lüfterhaube 9 axial zu dieser geöffnet sind. Auf ihrer Öffnungsseite sind die Ausnehmungen 12 von Nasen 14 flankiert, die den Innendurchmesser der Lüfterhaube 9 überschreiten, und welche an die Lüfterhaube 9 in ihrer Aufschubrichtung 13 stirnseitig anstößt.The fastening of the fan cover 9 consists of radially extending from the bearing plate 6, the F i g. 2 through 4 mounting brackets 10, which can be seen more clearly, to which the fan cover 9 is pushed in the axial direction is. These mounting brackets 10 have the fan shroud 9 radially on their circumference for receiving the penetrating self-tapping screws 11, recesses 12, which counter to the pushing-on direction 13 of the fan cover 9 are open axially to this. The recesses 12 of lugs 14 are on their opening side flanked, which exceed the inner diameter of the fan cover 9, and which to the fan cover 9 in their Push-on direction 13 abuts the front side.

Die Wirkungsweise der erfindungsgemäßen Befestigung der Lüfterhaube 9 besteht gemäß F i g. 1 darin, daß die Nasen 14 der Montageböckchen 10 beim Aufschieben der Lüfterhaube auf die Montageböckchen 10 in der Aufschubrichtung 13 einen Anschlag bilden. Die daraufhin durch den Umfang der Lüfterhaube 9 in die "Ausnehmungen 12 der Montageböckchen 10 eingesenkten Blechschrauben 11 machen ein Abziehen der Lüfterschraube 9 entgegen der Aufschubrichtung 13 unmöglich, so daß diese mit dem Lagerschild 6 und ebenso mit dem Motorgehäuse 1 fest verbunden ist.The mode of operation of the fastening according to the invention of the fan cover 9 is shown in FIG. 1 in that the lugs 14 of the mounting brackets 10 when the fan cover is pushed onto the mounting brackets 10 Form a stop in the pushing-on direction 13. The then through the circumference of the fan cover 9 in the "Recesses 12 of the mounting brackets 10 countersunk self-tapping screws 11 make a removal of the Fan screw 9 against the pushing-on direction 13 impossible, so that this with the end shield 6 and is also firmly connected to the motor housing 1.

Wie F i g. 1 ferner erkennen läßt, sind die Ausnehmungen 12 der Montageböckchen 10 wie diese selbst in axialer Richtung des Lagerschildes 6 aus den Gußformen entformbar. Damit können seitliche Schieber bei der Herstellung des Lagerschildes 6 im Spritzgußverfahren bzw. das spätere Anbringen von radialen Bohrungen in den Montageböckchen entfallen.Like F i g. 1 also reveals, the recesses 12 of the mounting brackets 10 are like these themselves in axial direction of the end shield 6 demoldable from the molds. This allows side slides for the production of the end shield 6 by injection molding or the subsequent attachment of radial bores omitted in the mounting brackets.
