Befestigung für die Lüfterhaube oder ähnlich gestaltete ringförmig geschlossene Teile von ElektromotorenAttachment for the fan cover or similarly designed ring-shaped closed parts of electric motors
Die Erfindung betrifft eine Befestigung für die Lüfterhaube oder ähnlich gestaltete ringförmig geschlossene Teile von Elektromotoren, 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. Bei bekannten Befestigungen dieser Art müssen die Ausnehmunoen 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 beträchtliehen Aufwand verbunden, den die Erfindung vermeiden will.The invention relates to a fastening for the fan cover or similarly designed ring-shaped closed parts of Electric motors, which are pushed on in the axial direction by a plurality of mounting brackets extending radially from the motor body are, in which recesses for receiving the part to be fastened penetrate radially on its circumference Self-tapping screws. In known fastenings of this type, the Ausnehmunoen the mounting bracket either Recessed during the injection molding of the engine body through the use of side slides or after the casting by subsequent drilling. Both options come with a considerable amount of money Cost associated with the invention wants to avoid.
Als Lösung der gestellten Aufgabe wird eine Weiterentwicklung der eingangs genannten Befestigung vorgeschlagen, die dadurch gekennzeichnet ist, daß die Ausnehmungen der Montageböckchen entgegen der Aufschubrichtung des zu befestigenden Teiles axial zu diesem geöffnet und auf ihrer Öffnungsseite von denAs a solution to the problem posed, a further development of the fastening mentioned above is proposed, which thereby is characterized in that the recesses of the mounting brackets counter to the pushing-on direction of the part to be fastened open axially to this and on its opening side of the

Innendurchmesser des zu befestigenden Teiles überschreitenden Nasen flankiert sind, an die das zu befestigende Teil in seiner Aufschubrichtung stirnseitig anstößt· Auf Grund dieser Merkmale ist es möglich, die Ausnehmungen aller Montageböck- chen in einer Richtung zu entformen und sotr. *t die Verwendung seitlicher Schieber bzw. das Anbringen von Bohrungen einzusparen. Infolgedessen wird der Herstellungsaufwand in der angestrebten Weise verringert. Noses exceeding the inner diameter of the part to be fastened are flanked against which the part to be fastened abuts on the front side in its push-on direction · Due to these features , it is possible to demold the recesses of all mounting brackets in one direction and thus * t to save the use of side slides or drilling holes. As a result, the manufacturing cost is reduced in the desired manner.
Ein Ausführungsbeispiel der Erfindung wird an Hand der Zeichnung beschrieben. Darin zeigen im einzelnen: Fig. 1 die teilweise Seitenansicht eines mit einer entsprechend den beanspruchten Merkmalen befestigten , Lüfterhaube ausgestatteten Elektromotors im Halbschnitt, An embodiment of the invention is described with reference to the drawing. They show in detail: Fig. 1 is a partial side view of a secured with a according to the claimed features, Fan cover equipped electric motor in half section,

The rear guidance of the rotor

welle 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 7 dient die mit AnSäugöffnungen 8 durchbrochene Lüfterhaube 9.Shaft 4 takes over the bearing plate 6 provided with the bearing 5, outside of which the rotor shaft 4 is fitted with the fan wheel 7 is. The fan cover 9, which is perforated with suction openings 8, serves as protection against contact for the fan wheel 7.
Die Befestigung der Lüfterhaube 9 besteht aus sich radial vom Lagerschild 6 aus erstreckenden, den Fig. 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 an welche die Lüfterhaube 9 in ihrer Aufschubrichtung 13 stirnseitig anstößt.The attachment of the fan cover 9 consists of radially from Bearing shield 6 from extending mounting brackets 10, which can be seen more clearly in FIGS. 2 to 4, to which the fan cover 9 is pushed in the axial direction. These mounting brackets 10 have the fan cover 9 on their circumference to accommodate the radially penetrating self-tapping screws 11, recesses 12, which axially close against the pushing-on direction 13 of the fan cover 9 these are open. On their opening side, the recesses 12 are flanked by lugs 14, which have the inner diameter exceed the fan cover 9, and against which the fan cover 9 abuts on the front side in its pushing-on direction 13.
Die Wirkungsweise der zur Beschreibung gelangenden Befestigung der Lüfterhaube 9 besteht gemäß Fig. 1 darin, daß die Nasen 14 der Montageböckchen 10 beim Aufschieben der Lüfterhaube 9 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 einoesenkt-en Blechschrauben 11 machen ein Abziehen der Lüfterhaube 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 action of the fastening used in the description 1 of the fan cover 9 consists in that the lugs 14 of the mounting brackets 10 open when the fan cover 9 is pushed on the mounting brackets 10 form a stop in the pushing-on direction 13. The then by the circumference of the fan cover 9 in the recesses 12 of the mounting brackets 10 Self-tapping screws 11 make a removal of the fan cover 9 against the pushing direction 13 impossible, so that this with the End shield 6 and is also firmly connected to the motor housing 1.

Wie Fig. 1 ferner erkennen läßt, sind die Ausnehmungen 12 der Montageböckchen 10 wie diese selbst in axialer Richtung des Lagerschildes 6 entformbar. Damit können seitliche Schieber bei der Herstellung des Lagerschildes 6 im Spritzgußverfahren bzw. das spätere Anbringen von radialen Bohrungen entfallen.As FIG. 1 also shows, the recesses 12 of the mounting brackets 10 are like these themselves in the axial direction of the Bearing shield 6 demoldable. This allows lateral slide in the manufacture of the end shield 6 in the injection molding process or there is no need to add radial bores later.
