Description

Die Erfindung bezieht sich auf einen insbesondere zum Antrieb eines Lüfters dienenden Elektromotor, bei dem ein mit einer Laufbuchse versehener Läufer auf einer in das Motorgehäuse einseitig eingesetzten Achse drehbar gelagert ist. Diese Ausführung hat sich als sehr- brauchbar erwiesen, erfordert jedoch noch einen verhältnismäßig großen Aufwand für die Herstellung und das genaue .zentrische Einsetzen der Achse. Die vorliegende Erfindung zeigt, wie dieser Aufbau des Lüfters noch weit vereinfacht und damit nicht unerheblich verbilligt werden kann.The invention relates to a particular one for driving a Fan serving electric motor, in which a rotor provided with a bushing is rotatably mounted on an axis inserted on one side in the motor housing. This implementation has proven very useful, but it requires one more relatively large effort for the production and the exact .zentrische insertion the axis. The present invention shows how this construction of the fan goes a long way can be simplified and thus not insignificantly cheaper.

Erfindungsgemäß sind zu diesem Zweck das Gehäuse, in idem einerseits das Ständerpaket und andererseits die den Läufer tragende -Achse eingebettet sind, und die Achse selbst "aus einem Sintermetall hergestellt. .Dadurch Ist die Möglichkeitgegeben, die Achse aus dem Motorgehäuse or--ganisch herauswachsen zu lassen, in dem sie erfindungsgemäß :zusammen mit dem Motorgehäuse gepreßt wird. Hierdurch ergibt sich eine besondere einfache und billige Herstellung fies Elcktroinotors.According to the invention are for this purpose the housing, in idem on the one hand the stator package and, on the other hand, the axis carrying the rotor are embedded, and the axle itself "made of a sintered metal. This gives the possibility of to allow the axle to grow organically out of the motor housing by using it according to the invention : is pressed together with the motor housing. This results in a special one simple and cheap production of nasty Elcktroinotors.

Eine weitere Verbesserung kann .gemäß der Erfindung ferner dadurch erzielt werden,. -daß- die Schmierung der Lagerstellen des Lüfters durch das Sintermetall hindurch erfolgt, wobei die übrige Gehäuseoberfläche insbesondere durch Aufspritzen eines ölnichtdurahlässigen Lackes oder durch ein anderes geeignetes Verfahren ölundurchlässig gemacht wird.A further improvement can .according to the invention also thereby be achieved,. -that- the lubrication of the fan bearings by the sintered metal takes place therethrough, the rest of the housing surface in particular by spraying an oil-non-permeable varnish or another suitable process that is oil-impermeable is made.

Besondere Querbohrungen für die Schmierung .der Lagerstellen, wie -sie bisher notwendig waren, können .dann erspart werden. Wenn die Preßformen so ausgebildet werden, daß die Achse maßhaltig gepreßt werden kann und die Befestigungsoberfläche senkrecht zur Achse steht, so erübrigt sich jede weitere Nacharbeit .des Motorgehäuses.Special cross bores for the lubrication of the bearing points, such as -They were previously necessary, can then be saved. If the molds like that be designed so that the axis can be pressed true to size and the mounting surface is perpendicular to the axis, no further reworking of the motor housing is necessary.

In der Figur ist ein Ausführungsbeispiel, des Erfindungsgegenstandes im Querschnitt dargestellt. i ist das :Gehä-use des Elektromotors, in dem das Ständerpalcet 2 gelagert ist. 3 ist .die Iden Läufer q tragende Achse, die in de Gehäuse i eingebettet ist. Das Gehäuse i und .die Achse 3 sind nun aus Sintereisen als ein einziges Werkstück hergestellt. Das in dem Schmiermittelbehälter 15 befindliche Öl kann nun durch die hohle Achse 3 unmittelbar nach den Lagerstellen .der Laufbuchse 16 des Läufers q. hindurchsickern. Die Gehäuseoberfläche ist durch Aufspritzen eines ö1.nichtdur,chlässigen Lackes öd. u (durchlässig gemacht, so @daß Klas von ,den Lagerstellen abströmende Öl wieder nachdem Ölbehälter 15 zurückfließt. Das Flügelrad io ist mittels der über den Motor gezogenen Haube ig an der Kappe i9 am Läufer 4 befestigt.The figure shows an exemplary embodiment of the subject matter of the invention shown in cross section. i is that: the housing of the electric motor in which the stand pallet 2 is stored. 3 is .the Iden rotor q bearing axis, which is embedded in de housing i is. The housing i and the axis 3 are now made of sintered iron as a single workpiece manufactured. The oil in the lubricant reservoir 15 can now through the hollow axis 3 immediately after the bearing points .der sleeve 16 of the rotor q. seep through. The surface of the housing is non-negligible due to the spraying of an oil Lackes öd. u (made permeable, so @ that class flowing off from the bearing points Oil again after oil tank 15 flows back. The impeller io is by means of the over the motor-drawn hood ig attached to the cap i9 on the rotor 4.
