Description
Die -Erfindung bezieht sich. auf Läufer --von Motoren öder auch Generatoren, insbesondere auch solche, die starken mechanischen Erschütterungen ausgesetzt sind und bei denen -Vorsorge getroffen werden mußi, daß! die Wicklungen .durch die Erschütterungen nicht beschädigt werden und. auch z. B. die Verbindungsleitungen zwischen Wicklung-und Kommutator nicht zerstört werden. Zu diesem Zweck ist in bekannter Weise zwischen dem Blechpaket des Ankers und dem Kommutator oder auch an der entgegengesetzten Seite des Läufers eine Füllmasse angebracht, in die die Wicklungsenden bzw.. die Verbindungen zum Kommutator fest eingebettet sind.. Die Füllmasse kann außen in an sich bekannter Weise mit einer Metallkappe, -umgeberrsein, welche die mechanische Festigkeit der Füllung steigert.The invention relates. on rotors - from motors or generators, especially those that are exposed to strong mechanical vibrations and where -provisions must be taken that! the windings .by the vibrations not be damaged and. also z. B. the connecting lines between winding and Commutator cannot be destroyed. For this purpose is in a known manner between the laminated core of the armature and the commutator or on the opposite one Side of the rotor attached a filling compound into which the winding ends or .. the Connections to the commutator are firmly embedded. The filling compound can be outside in in a known manner with a metal cap, -umgeberrsein, which the mechanical Increases the strength of the filling.
Gemäß der Erfindung werden in die- Füllmasse, Rippen eingesetzt, !die die Festigkeit erhöhen. Außerdem macht sich bei derartigen Läufern mit Füllmassen der Nachteil bemerkbar, däß die Wärmeabgabe der Wicklungen an die Außenluft herabgesetzt isst, so daß eine stärkere Ervvärmüng im Läufer eintritt, als dies @sonst der Fall ist. Die gemälß: der Erfindung in die Isoliermasse eieingesetzten Rippen führen, wenn .sie- aus gut wärmeleitenden Stoffen bestehen, die im Innern auftretende Wärme nach außen ab. Um die Wärmeabgabe an die Außenluft zu erhöhen, können die Rippen gemäß der Erfindung aus :der Isoliermasse nach außen hinausragen.According to the invention, ribs are used in the filling compound,! increase strength. In addition, such runners with filling compounds make themselves felt the disadvantage noticeable that the heat dissipation of the windings to the outside air is reduced eats, so that a stronger warming occurs in the runner than @ otherwise the case is. According to the invention, the ribs inserted into the insulating compound lead, if .they consist of materials that conduct heat well, the heat generated inside outwards. To increase the heat dissipation to the outside air, the fins according to the invention from: the insulating compound protrude to the outside.
In der Fig. i und 2 sind zwei Ausführungsbeispiele der Erfindung dargestellt. Auf der Welle e sitzt das Läuferpaket 2. Die Wicklungsenden sind in die Füllmasse 3 eingebettet, die außen eine aus Metall bestehende Kappe 4 hat. Unter der Metallkappe kann in an sich bekannter Weise eine Faserschicht 5 angeordnet sein.. Gemäß der Erfindung sind nun nach Fig. i Rippen 6 in -die Füllmasse eingebaut. Die Rippen durchsetzen die-Füllmasse und -ragen nach außen hervor, wodurch neben Erhöhung der Festigkeit der Füllmasse eine gute Wärmeabgabe an. die Außenluft erreicht wird. Die Rippen können mit der Metallkappe 4 metallisch verbunden seid.Two exemplary embodiments of the invention are shown in FIGS. The rotor core 2 sits on shaft e. The winding ends are in the filling compound 3 embedded, which has a metal cap 4 on the outside. Under the metal cap a fiber layer 5 can be arranged in a manner known per se .. According to FIG Invention are now built into the filling compound according to Fig. I ribs 6. Ribs enforce the filling compound and protrude outwards, which in addition to increasing the Strength of the filler a good heat dissipation. the outside air is reached. The ribs can be metallically connected to the metal cap 4.
Fig.2 zeigt eine Anordnung der Rippen, in axialer. Richtung. Die Rippen lassen sich mit dem Metallkörper aus einem Stück herstellen, und zwar zweckmäßig aus Spritzguß. Die Anordnung der Kühlrippen nach Fig. 2 hat gleichzeitig eine Lüfterwirkung. Um diese zu unterstützen, können natur-@gemäß- die Rippen nach Fig. i oder 2 außen entsprechend geschränkt ausgeführt werden.Fig.2 shows an arrangement of the ribs, in an axial. Direction. Ribs can be made in one piece with the metal body, and in fact expediently from injection molding. The arrangement of the cooling fins according to FIG. 2 also has a fan effect. In order to support this, the ribs according to FIG. 1 or 2 can naturally- @ according to the outside be executed accordingly restricted.
