Die Aufgabe wird auch gelöst durch eine rotierende Maschine, insbesondere Elektromotor, aufweisend ein Gehäuse, einen Ro tor und ein innerhalb des Gehäuses angeordnetes Bauteil mit einer wenigstens einer Vertiefung aufweisenden Außenfläche, wobei das Bauteil am Gehäuse fixiert ist, indem das Gehäuse im Bereich der Vertiefung insbesondere mittels Pulsfügen oder mittels eines Pressstempels formschlüssig in die Vertiefung eingebettet ist.The Task is also solved by a rotating machine, in particular electric motor, comprising a housing, a ro tor and a disposed within the housing component with an at least one recess having outer surface, wherein the component on the housing is fixed by the housing in the region of the recess, in particular by means of pulse joining or by means of a press ram form-fitting embedded in the depression is.
Die erfindungsgemäße rotierende Maschine, bei der es sich insbesondere um einen Elektromotor handelt, umfasst demnach das innerhalb des Gehäuses angeordnete Bauteil. Die Außenfläche dieses Bauteils umfasst wenigstens eine Vertiefung, d. h. die Außenkontur des Bauteils weist eine vertiefte Geometrie auf. Das Bauteil ist z. B. ein Kunststoffspritzgussteil und ist innerhalb des Gehäuses angeordnet und an diesem fixiert, indem Gehäusematerial im Bereich der Vertiefung formschlüssig in die Vertiefung eingebettet ist. Diese formschlüssige Verbindung erhält man erfindungsgemäß insbesondere mittels Pulsfügen oder unter Verwendung eines Pressstempels, der verwendet wird, das Gehäuse im Bereich der Vertiefung formschlüssig in die Vertiefung hinein zu pressen. Pulsfügen ist eine Technik, die auch unter dem Begriff ”EMPT” (Elektromagnetische Puls Technologie) bekannt ist und die Kraftwirkung eines impulsförmigen Magnetfeldes direkt zur Beschleunigung insbesondere flacher oder zylindrischer Strukturen aus elektrisch leitfähigem Material ausnutzt. Durch Anlegen des Magnetfeldes wird das Gehäuse im Bereich der Vertiefung in diese formschlüssig hinein gepresst.The rotating invention Machine, which is in particular an electric motor, therefore comprises the component disposed within the housing. The Outer surface of this component includes at least one well, d. H. the outer contour of the component has a recessed geometry. The component is z. B. a plastic injection molded part and is inside the case arranged and fixed to this by housing material in the area of Recess positive fit embedded in the depression. This positive connection receives in particular according to the invention by pulse joining or using a ram that is used casing in the recess in the form of a positive fit into the recess press. pulse welding is a technique also known as EMPT (Electromagnetic Pulse Technology) is known and the power of a pulsed magnetic field directly for acceleration especially flat or cylindrical structures made of electrically conductive Material exploits. By applying the magnetic field, the housing is in the range the depression in this form-fitting pressed into it.
Ein Vorteil des erfindungsgemäßen Verfahrens kann sein, dass mit relativ geringem Passungsaufwand oder mittels zusätzlicher Bearbeitung oder Befestigungsaufwand eine ausreichend feste Verbindung zwischen dem Gehäuse und dem Bauteil erzeugt werden kann. Das Gehäuse kann beispielsweise aus Metall, z. B. Aluminium oder Stahl, gefertigt sein.One Advantage of the method according to the invention may be that with relatively little fit or by means of additional Machining or mounting effort a sufficiently strong connection between the case and the component can be produced. The case may be made, for example Metal, e.g. As aluminum or steel, be made.
Das Bauteil ist gemäß Varianten der erfindungsgemäßen rotierenden Maschine als eine Kontaktiervorrichtung, die eingerichtet ist, die rotierende Maschine elektrisch zu kontaktieren, als eine Rotorlagerung, mittels der der Rotor drehbar innerhalb des Gehäuses gelagert ist, oder als eine Kontaktiervorrichtung mit integrierter Rotorlagerung ausgebildet sein. Die Rotorlagerung kann beispielsweise als eine Scheibe ausgeführt sein.The Component is in accordance with variants the rotating invention Machine as a contacting device, which is set up Contact rotating machine electrically, as a rotor bearing, by means of which the rotor is rotatably mounted within the housing, or as be formed a contacting with integrated rotor bearing. The rotor bearing can for example be designed as a disc.
Die Außenfläche des Bauteils kann wenigstens einen insbesondere einstückig am Bauteil angeformten Zentrierfinger aufweisen, mittels dem das Bauteil an einem Stator der rotierenden Maschine zentriert angeordnet ist. Das Bauteil kann vorgesehen sein, am Stator angeordnet, insbesondere befestigt zu werden. Um eine genaue Anordnung zu erleichtern, kann die erfindungsgemäße rotierende Maschine den Zentrierfinger aufweisen.The Outside surface of the Component can at least one in particular integrally on Component integrally formed centering finger, by means of which the component is centered on a stator of the rotating machine. The component can be provided, arranged on the stator, in particular to be attached. To facilitate an accurate arrangement, can the rotating invention Machine have the centering finger.
Für eine erleichterte Montage kann der Stator an seiner Mantelfläche eine insbesondere als Nut ausgebildete Ausnehmung aufweisen, in der der Zentrierfinger geführt ist.For a relief Assembly, the stator on its lateral surface formed in particular as a groove Have recess in which the centering finger is guided.
Die Vertiefung kann insbesondere im Bereich des Zentrierfingers an der Außenfläche des Bauteils angeordnet sein. Der Zentrierfinger, der beispielsweise spritztechnisch am Bauteil erzeugt wurde, ist gemäß diesen Varianten vorgesehen, in die Statoraußengeometrie einzugreifen. Somit liegt der Zentrierfinger radial zwischen dem Stator und dem Gehäuse. Der Stator bildet somit eine radiale Abstützung, die ein Ausweichen des Zentrierfingers insbesondere beim Pulsfügen oder Verpressen verhindert.The Deepening can, in particular in the area of the centering finger on the Outer surface of the component be arranged. The centering finger, for example, by injection molding has been generated on the component is provided according to these variants, in the stator outer geometry intervene. Thus, the centering finger is located radially between the Stator and the housing. The stator thus forms a radial support, which is a deflection of the Zentrierfingers especially during pulse joining or pressing prevented.
Der Zentrierfinger kann den zusätzlichen Effekt aufweisen, dass der Stator im Gehäuse rotationssymmetrisch zentriert wird, was z. B. das Pulsfügeergebnis in Richtung Symmetrie positiv beeinflusst.The centering finger may have the additional effect that the stator is rotationally symmetrical centered in the housing, which z. B. the Pulse result in the direction of symmetry positively influenced.
Auch bei unterschiedlichen Materialkombinationen, z. B. Kunststoff-Bauteil und Stahl-Gehäuse kann die formschlüssige Verbindung ihre Festigkeit beibehalten, da der Zentrierfinger relativ dünn ausgebildet sein kann und von daher, wenn, dann nur eine unwesendliche Ausdehnung bei Temperatusschwankungen zu erwarten ist und die Vertiefung unterschiedliche Materialausdehnenungen ausgleichen kann.Also at different material combinations, eg. B. plastic component and steel housing can the form-fitting Compound maintain their strength, since the centering finger relative thinly formed and therefore, if so, then only an inconceivable extension is expected in Temperatusschwankungen and the deepening different Balancing Materialausdehnenungen can compensate.
