Abstract
Description
Die Erfindung betrifft eine Lagerung eines Rotors für eine Elektromaschine und ein Verfahren zur Herstellung der Lagerung.The The invention relates to a bearing of a rotor for an electric machine and a method for producing the storage.
Beispielsweise bei Elektromotoren ist es bekannt, dass man danach strebt, einen Spalt zwischen Anker und Stator zur Erzielung eines hohen Wirkungsgrades gleichmäßig möglichst klein zu halten.For example in electric motors, it is known that one strives for, one Gap between armature and stator to achieve high efficiency evenly as possible to keep small.

Aus der WO 98/44619 A1 ist weiterhin ein Verfahren zur Herstellung eines Mikromotors bekannt, das folgende Schritte umfasst: Aufschieben von Statorkomponenten auf einen starren Dorn, Einbringen des Dornes mit den Statorkomponenten in eine Spritzgussform, Injizieren eines Polymermaterials in die Spritzgussform zur Bildung eines Motorgehäuses, Entfernen der Spritzgussform und des Dornes von dem Motorgehäuse und Einschieben eines Rotors in das Motorgehäuse, wobei der Außendurchmesser des Stators geringfügig kleiner ist als derjenige des Dornes.Out WO 98/44619 A1 is also a process for producing a Micromotor known, comprising the following steps: sliding on Stator components on a rigid mandrel, inserting the mandrel with the stator components in an injection mold, injecting a Polymer material in the injection mold to form a motor housing, removing the injection mold and the mandrel of the motor housing and Inserting a rotor into the motor housing, the outer diameter of the stator slightly smaller than that of the thorn.
Die Aufgabe der Erfindung ist es dabei, eine Lagerung eines Rotors für eine Elektromaschine sowie ein Verfahren zur Herstellung der Lagerung zu schaffen, so dass sich ein gleichmäßiger, besonders geringer Spalt zwischen dem Rotor und einem Statorteil der Elektromaschine erzielen lässt und zugleich ein Deckelelement mit einem Lager für den Rotor im Statorteil einfach und exakt positioniert werden kann.The The object of the invention is to provide a bearing of a rotor for an electric machine as well as to provide a method of manufacturing the storage, so that is a uniform, especially low Gap between the rotor and a stator of the electric machine achieve and at the same time a lid member with a bearing for the rotor in the stator easily and can be positioned exactly.
Die Aufgabe wird hinsichtlich der Vorrichtung durch den Gegenstand des Patentanspruchs 1 und hinsichtlich dem Verfahren durch den Gegenstand des Patentanspruchs 19 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The The object is with respect to the device by the subject of the Patent claim 1 and in terms of the method by the subject matter of Patent claim 19 solved. Advantageous embodiments are described in the subclaims.
Gemäß Anspruch 1 beinhaltet eine Lagerung eines Rotors für eine Elektromaschine folgende Merkmale:
- – Ein Statorkörper ist in einem Statorgehäuse befestigt,
- – ein erster axialer Abschnitt des Statorgehäuses ist mit einem ersten Lager für den Rotor über einen zwischen dem Abschnitt und dem Lager angeordneten ersten Kunststoffkörper verbunden,
- – das Statorgehäuse ist in einem zweiten axialen Abschnitt mit einem zweiten Kunststoffkörper mit einer Mantelfläche als Anlagefläche für ein dazu passend geformtes Deckelelement mit einem zweiten Lager für den Rotor ausgebildet, und
- – das Deckelement umfasst einen dritten Kunststoffkörper mit einer zum Anliegen an der Mantelfläche des zweiten Kunststoffkörpers vorgesehenen Mantelfläche.
- A stator body is mounted in a stator housing,
- A first axial section of the stator housing is connected to a first bearing for the rotor via a first plastic body arranged between the section and the bearing,
- - The stator housing is formed in a second axial portion with a second plastic body having a lateral surface as a contact surface for a matingly shaped lid member with a second bearing for the rotor, and
- - The cover member comprises a third plastic body with a provided for abutment on the lateral surface of the second plastic body lateral surface.
Die Erfindung beruht dabei auf der Erkenntnis, dass durch den Einsatz der Kunststoffkörper bei gleichzeitiger, vergleichsweise einfacher und kostengünstiger Herstellbarkeit die den Rotor lagernden Lager derart im Stator befestigbar sind, dass die Mittenachsen der Öffnungen von Innenringen der Lager mit einer Mittenachse einer den Rotor aufnehmenden Höhlung des Stators exakt übereinstimmen, so dass letztendlich der Rotor mit einem gleichmäßigen, minimalen Spalt zum Stator hin betreibbar ist, was sich unter anderem positiv auf den Wirkungsgrad der Elektromaschine auswirkt.The invention is based on the finding that by using the plastic body at the same time, relatively simple and cost favorable manufacturability of the rotor bearing bearings are mounted in the stator so that the center axes of the openings of inner rings of the bearing with a center axis of the rotor receiving cavity of the stator exactly match, so that ultimately the rotor with a uniform, minimum gap to the stator operable out is what has a positive effect on the efficiency of the electric machine.
