Abstract
Elektromotor (1) mit einem einen Flansch (9) aufweisenden topfförmigen Gehäuse (2), einem Bürstenträger (3), einem Rotor (4), der in einem Lager (5) gelagert ist, das in einem Lagertragteil (6) aufgenommen ist und einem O-Ring (7), der als Dichtung zwischen dem Gehäuse (2) und dem Lagertragteil (6) dient, wobei der O-Ring (7) in einen Aufnahmeraum (8) eingelegt ist, der durch das Gehäuse (2), den Bürstenträger (3) und das Lagertragteil (6) begrenzt ist, und wobei der Bürstenträger axial vom Lagertragteil (6) abgestützt wird, dadurch gekennzeichnet, dass der Flansch (9) als axiale Begrenzung des Aufnahmeraums (8) dient, das Lagertragteil (6) eine stufenförmige Vertiefung (11) mit einer inneren Zylindermantelfläche (13) als äußere radiale Begrenzungsfläche und einer axialen Ringfläche (14) als axiale Begrenzungsfläche des Aufnahmeraums (8) aufweist und der Bürstenträger (3) axial an dem Flansch (9) und radial an einer Innenfläche (12) des Lagertragteils (6) anliegt.electric motor (1) with a cup-shaped housing (2) having a flange (9), a brush holder (3), a rotor (4) which is mounted in a bearing (5), which in a Lagertragteil (6) is received and an O-ring (7), as Seal between the housing (2) and the bearing support member (6), wherein the O-ring (7) in a Receiving space (8) is inserted through the housing (2), the brush holder (3) and the bearing support member (6) is limited, and wherein the brush support is axially supported by the bearing support part (6) is characterized in that the flange (9) as the axial boundary of Receiving space (8), the bearing support member (6) is a stepped recess (11) with an inner cylinder jacket surface (13) as outer radial Boundary surface and an axial annular surface (14) as an axial boundary surface the receiving space (8) and the brush holder (3) axially on the flange (9) and radially on an inner surface (12) of the bearing support member (6) is applied.
Description
Die
Erfindung betrifft einen Elektromotor (
Bei bekannten Elektromotoren sind die O-Ringe in Nuten eingelegt, die in der Stirnseite entweder des Lagertragteils oder des Gehäuses eingebracht sind. Bei tiefgezogenen Gehäusen ist es jedoch kaum möglich, ohne ein aufwändiges spanendes Verfahren zu verwenden, eine Nut einzubringen. Bei Lagertragteilen, die aufgrund ihrer Größe oder Komplexität spanend hergestellt werden müssen, insbesondere wenn ein Stufenbohrer für die Herstellung von Lager- und Bürstenträgeraufnahme etc. verwendet wird, wäre das spanende Herstellen einer Nut mit zusätzlichem Aufwand durch Umspannen etc. verbunden, so dass keine wirtschaftliche Herstellung möglich ist.at known electric motors, the O-rings are inserted in grooves, the introduced in the front side of either the Lagertragteils or the housing are. For deep-drawn housings However, it is hardly possible without a complex To use cutting method to introduce a groove. For bearing part, which are cutting because of their size or complexity must be made, in particular if a step drill for the production of bearing and brush holder holder etc. would be used the machining producing a groove with additional effort by re-clamping etc., so that no economical production is possible.

der vorliegenden Erfindung am nächsten
liegender Elektromotor ist aus der
Bei
der
Daher ist es Aufgabe der vorliegenden Erfindung bei einem Elektromotor der eingangs genannten Gattung dafür zu sorgen, dass ein O-Ring auch bei Verwendung eines tiefgezogenen Gehäuses und eines gebohrten Lagerträgers einwandfrei und prozesssicher montiert werden kann.Therefore It is the object of the present invention with an electric motor the genus mentioned above to ensure that an O-ring even when using a deep-drawn housing and a drilled bearing support properly and can be mounted reliably.
Diese
Aufgabe wird erfindungsgemäß dadurch

dass der Flansch (
Eine Weiterbildung der Erfindung wird im Anspruch 2 dargestellt, wonach eine vierte Begrenzungsfläche des Aufnahmeraums erfindungsgemäß durch eine Zylindermantelfläche des Bürstenträgers gebildet wird.A Development of the invention is shown in claim 2, which a fourth boundary surface the receiving space according to the invention by a cylindrical surface formed of the brush holder becomes.
Um eine sichere Montage des O-Rings zu gewährleisten wird zunächst das Gehäuse mit Statorteilen und dem Rotor vormontiert, wobei der Rotor bereits mit dem Bürstenträger und dem Lager versehen ist, dann der O-Ring über den zylinderringförmigen Bereich des an dem Flansch des Gehäuses anliegenden Bürstenträgers montiert und schließlich das Lagertragteil auf den vormontierten Bürstenträger und den Flansch des Gehäuses zur Anlage gebracht und verschraubt.Around To ensure a secure assembly of the O-ring is the first casing premounted with stator parts and the rotor, the rotor already with the brush holder and the bearing is provided, then the O-ring on the cylindrical annular area of the voltage applied to the flange of the housing Brush holder mounted and finally that Lagertragteil on the preassembled brush holder and the flange of the housing to Attached and screwed.
