Description
Häfiganker und Verfuhren zur Herstellung desselben. Gegenstand vorlieriender Erfindung ist ein Käfiganker, dessen Kurzschlussringe an gegossen sind.
Die Erfindung betrifft gleichzeitig ein Verfahren zur Herstellung von solchen Kä figankern. Zweckmässigerweise werden die seitlichen Enden von im Blechkörper ein gelegten Kupferleitern zugleich umgossen. Gleichzeitig mit den Kurzschlussringen kön nen auch die Ankerleiter gegossen werden.
In beiliegender Zeichnung sind zwei Aus führungsbeispiele des Erfindungsgegenstan des dargestellt, und zwar zeigt: Fig. 1 einen Axialschnitt durch einen Käfiganker, als Aussenanker und Rotor aus gebildet, Fig. 2 einen Schnitt durch den Anker nach der Linie a-a der Fig. 1, Fig. 3 einen Axialschnitt durch eine an dere Ausführungsform des Käfigankers als Innenanker ausgebildet, und Fig. 4 einen Schnitt durch diesen Anker nach der Linie b-b der Fig. 3.
Bei der Ausführungsform gemäss Fig. 1 und 2 wird das zusammengenietete Blech- paket 1, das mit durchgehenden Querlöchern 2 für Ankerleiter 3 versehen ist, in die Sand- oder Kokillenform, die entsprechend geformt ist, gelegt und mit einem elektrisch gut lei tenden Metall, beispielsweise Aluminium, beidseitig derart umgossen, dass zwei Kurz- sehlussringe 4 entstehen, die untereinander mittelst der Ankerleiter 3 leitend verbunden sind. Das umgossene Blechpaket wird an sind. Das umgossene Blechpaket wird an einem Armstern oder einer glockenförmig ausgebildeten Radscheibe 5 starr angebracht, welcher mit Bohrung 6 für die Welle ver sehen ist.
Bei der Ausführungsform gemäss Fig.3 und 4 ist das zusammengenietete Blechpaket 1 mit Querlöchern versehen, in welche An kerleiter 3 mit abgesetzten Enden 7 ange bracht sind. Ähnlich wie bei der ersten Aus führungsform wird das Blechpaket mit den Ankerleitern in eine Gussform gelegt und beidseitig mit einem elektrisch gut leitenden Metall ungossen, so dass zwei Kurzschluss ringe 4 entstehen, die aber in diesem Falle Mittelst der vorher angebrachten Ankerleiter 3 leitend verbunden sind.
Das umgossene Blechpaket wird in it einer zweiteiligen -Nabe 8 starr verbunden, die mit Bohrung 6 für die Welle verseben ist.
Der Käfiganker kann ebenfalls bei Aus- fübrung als Aussenanker als Stator ausgebil det werden, wobei das umgossene Blechpaket an dem Gehäuse des Motors starr angebracht wird.
Framing anchors and methods of manufacturing the same. The subject of the present invention is a cage armature whose short-circuit rings are cast on.
The invention also relates to a method for producing such cages. Conveniently, the lateral ends of a copper conductors laid in the sheet metal body are encapsulated at the same time. The armature conductors can also be cast at the same time as the short-circuit rings.
In the accompanying drawings, two exemplary embodiments of the subject matter of the invention are shown, namely: FIG. 1 shows an axial section through a cage anchor, formed as an outer anchor and rotor, FIG. 2 shows a section through the anchor along the line aa in FIG. 1, FIG 3 shows an axial section through another embodiment of the cage anchor designed as an inner anchor, and FIG. 4 shows a section through this anchor along the line bb of FIG.
In the embodiment according to FIGS. 1 and 2, the riveted sheet-metal package 1, which is provided with through transverse holes 2 for armature conductors 3, is placed in the sand or chill mold, which is shaped accordingly, and covered with a metal with good electrical conductivity, for example aluminum, encapsulated on both sides in such a way that two short-circuit rings 4 are created, which are conductively connected to one another by means of the armature conductor 3. The encapsulated sheet metal package will be on. The cast laminated core is rigidly attached to an arm star or a bell-shaped wheel disc 5, which is seen ver with hole 6 for the shaft.
In the embodiment according to FIGS. 3 and 4, the riveted laminated core 1 is provided with transverse holes, in which to kerleiter 3 with stepped ends 7 are introduced. Similar to the first embodiment, the laminated core with the armature conductors is placed in a mold and cast on both sides with an electrically conductive metal, so that two short-circuit rings 4 are created, but in this case they are conductively connected to the previously attached armature conductors 3.
The cast laminated core is rigidly connected in it with a two-part hub 8, which is offset with a hole 6 for the shaft.
The cage armature can also be designed as an external armature as a stator, with the encapsulated laminated core being rigidly attached to the housing of the motor.
