Abstract
Description
Die
Erfindung betrifft einen Kommutatormotor, mit einem elektrisch leitenden
Lagerschild (
Aus
der
Daher ist es Aufgabe der vorliegenden Erfindung bei hohen zu fertigenden Stückzahlen eine sehr geringe Fehlerrate zu erreichen, wobei eine einfache Montage der Bauteile gegeben und nur eine geringe Teileanzahl nötig ist.Therefore It is an object of the present invention at high to be produced numbers to achieve a very low error rate, with a simple assembly given the components and only a small number of parts is necessary.
Diese
Aufgabe wird erfindungsgemäß dadurch
gelöst,
dass der Lagerschild (
Wie an sich aus dem Stand der Technik bekannt ist, können Leitbleche auch mit Steckkontakten einstückig ausgebildet sein, so dass weiter die Teileanzahl reduzierbar ist. Durch die unmittelbare Befestigung des Leitblechs am Lagerschild ist hierdurch eine hohe mechanische Festigkeit, wie sie beim Steckvorgang erforderlich ist, gewährleistet.As is known per se from the prior art, baffles can also be integrally formed with plug contacts be, so that further the number of parts is reducible. By the direct attachment of the baffle on the bearing plate is thus a high mechanical strength, as required during the insertion process is guaranteed.
Als elektronische Bauteile kommen insbesondere Kondensatoren oder Drosselspulen in Betracht, die mit der Motormasse in Form einer Entstörbeschaltung des Kommutatormotors elektrisch zu verbinden sind.When Electronic components come in particular capacitors or inductors into consideration, with the engine mass in the form of a suppression circuit of the commutator motor are to be electrically connected.
Vorteilhafterweise
ist vorgesehen, dass sich der Vorsprung (
Zweckmäßig ist
es den Vorsprung zylindrisch auszugestalten und das Leitblech im
Verbindungsbereich mit dem Vorsprung (
Um die Verbindung noch sicherer zu machen wählt man einen ausgeprägten Vorsprung, der sich im montierten Zustand noch deutlich über das Leitblech hinaus erstreckt. Daher ist eine Freisparung im Bürstenträger in Form einer Ausnehmung oder eines Durchbruchs erforderlich, um eine sichere Montage auch unter Toleranzgesichtspunkten sicherzustellen.Around make the connection even more secure you choose a distinct advantage in the mounted state still extends well beyond the baffle out. Therefore, a cutout in the brush holder is in shape a recess or a breakthrough required to secure Ensure assembly even under tolerance aspects.
Je nach Ausgestaltung und Auslegung kann die elektrische Verbindung zwischen dem Leitblech und dem Lagerschild auch zur mechanischen Befestigung des Bürstenträgers verwendet werden. Dadurch wird entprechender Bauraum für gesonderte Befestigungspunkte eingespart.ever according to design and interpretation, the electrical connection between the baffle and the bearing plate also for mechanical Attaching the brush holder used become. This entprechender space for separate attachment points saved.
Der
Bürstenträger (
Das
Leitblech kann mit dem Bürstenträger auf
unterschiedliche Weise verbunden sein. Eine Möglichkeit besteht darin, dass
das Leitblech (
Das Leitblech enthält eine Reihe von Bereichen, die im endmontierten Zustand unterschiedliche Knotenpunkte der Entstörbeschaltung und der Spannungsversorgung des Motors bilden. Dementsprechend müssen vorhandene mechanische Hilfsbrücken nach der Befestigung am Bürstenträger oder nach dem Umspritzen unterbrochen werden um eine funktionsfähige Motorbeschaltung darzustellen.The Contains baffle a number of areas that in the final assembled state different nodes the suppression circuit and the power supply of the motor. Accordingly, existing mechanical auxiliary bridges after attachment to the brush holder or after the overmolding be interrupted by a functional engine circuit display.
Zur Spannungsversorgung des Kommutatormotors können Litzen vorgesehen sein, die mit dem Leitblech verschweißt sind. Da der Schweißvorgang jedoch vor der Endmontage durchgeführt werden muss wäre eine elegantere Methode dadurch möglich, dass die Litzen mit Crimpkontakten versehen sind wodurch die Litzen erst nach der Endmontage des Motors aufgesteckt werden können. Dadurch wird vermieden dass die unhandlichen Litzen durch sämtliche Montageprozesse „hindurchgeschleift" werden müssen.to Power supply of the commutator motor can be provided strands, welded to the baffle are. However, the welding process performed before the final assembly would have to be a more elegant method possible in that the strands with Crimp contacts are provided whereby the strands only after the final assembly of Motors can be plugged. This avoids that the unwieldy strands through all Assembly processes must be "looped through".
Als alternative Möglichkeit für die Verbindung zwischen Lagerschild und Leitblech wird vorgeschlagen statt eines Vorsprungs am Lagerschild eine Ausnehmung vorzusehen in der sich radial nach außen vorspringende Klemmzungen eines daran adaptierten Leitblechs verkrallen können.When alternative possibility for the Connection between bearing plate and baffle is proposed Instead of a projection on the bearing plate to provide a recess in the radially outwardly projecting Clamping tongues of an adapted baffle can dig into it.
Die Montage von Leitblech, Bürstenträger und des elektronischen Bauteils kann auf unterschiedliche Weise geschehen. Entweder wird das Leitblech zunächst mit dem Bürstenträger verbunden, das elektronische Bauteil zugeführt und am Leitblech festgeschweißt und anschließend Aufsetzen dieser vormontierten Baugruppe auf den Lagerschild und Festklemmen am Vorsprung oder es wird zuerst der Bürstenträger auf den Lagerschild aufgesetzt dann das Leitblech zugeführt und schließlich das elektronische Bauteil verschweißt.The Assembly of baffle, brush holder and The electronic component can be done in different ways. Either the baffle first connected to the brush holder, supplied to the electronic component and welded to the baffle and subsequently Placing this preassembled module on the bearing plate and Clamp on the projection or it will first on the brush holder put on the end shield then fed the baffle and after all the electronic component welded.
Falls mehrere Bauteile mit dem Leitblech zu verschweien sind, werden diese vorzugsweise mit nur einer Schweißvorrichtung in einem Arbeitsgang vorzugsweise durch Widerstandsschweißen gefügt.If several components with the baffle are verschweien, these are preferably with only one welding device in one operation preferably by resistance welding together.
