Description
Geschlossene elektrische Hochspannungsmaschine mit außenbelüftetem Rippengehäuse Die Erfindung bezieht sich auf eine geschlossene elektrische Hochspannungsmaschine mit außenbelüftetem, an das Ständerblechpaket unmittelbar anliegendem Rippengehäuse für größere Leistungen über 100 kW. Die Abführung der Wärme von der Lagerschale an die Außenluft bereitet bei solchen Maschinen erhebliche Schwierigkeiten. Die bekannte Wasser-oder Ölkühlung der Lager erfordert einen komplizierten Aufbau der Lager und verteuert die Maschine erheblich.Closed high voltage electric machine with externally ventilated Rib housing The invention relates to an enclosed high-voltage electrical machine with externally ventilated rib housing directly adjacent to the stator core for greater powers over 100 kW. The dissipation of heat from the bearing shell to the outside air causes considerable difficulties with such machines. the known water or oil cooling of the bearings requires a complicated structure of the Warehouse and makes the machine considerably more expensive.
Die Erfindung löst diese Aufgabe auf einfachere Weise. Erfindungsgemäß bestehen die Lagerkörper und vorzugsweise auch das Gehäuse aus Aluminium od. dgl. und haben die Lagerkörper axial gerichtete Kühlrippen und bei Gleitlagerausführung die Lagerschalen tragende und mit der Lagerkörperwand verbundene Stege.The invention solves this problem in a simpler way. According to the invention consist the bearing body and preferably also the housing made of aluminum or the like. and the bearing bodies have axially directed cooling fins and in the case of plain bearing designs webs carrying the bearing shells and connected to the bearing body wall.
Gehäuse aus Aluminium sind bei elektrischen Maschinen an sich bekannt, jedoch nur bei Maschinen mit kleineren Leistungen unter 100 kW und vorwiegend zu dem Zweck, das Maschinengewicht herabzusetzen. Auch für Umformer sind bereits Aluminiumgehäuse vorgeschlagen worden, um eine magnetische Kopplung zwischen den einzelnen Maschinen zu verhindern.Housings made of aluminum are known per se in electrical machines, however only for machines with smaller outputs below 100 kW and predominantly too the purpose of reducing the weight of the machine. Aluminum housings are also already available for converters has been proposed to create a magnetic coupling between each machine to prevent.
Die Erfindung soll an Hand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. Sie zeigt eine oberflächengekühlte elektrische Maschine teils im Längsschnitt, teils in Seitenansicht.The invention is based on the embodiment shown in the drawing are explained in more detail. It shows a surface-cooled electrical machine partly in longitudinal section, partly in side view.
Das das Ständerblechpaket 1 unmittelbar umgebende fußlose Rippengehäuse 2 besteht aus Aluminium und ist in bekannter Weise an den doppelwandigen Gehäuseschilden 3 aus Gußeisen befestigt, die mit den Konsolen 4 aus einem Stück bestehen. Auf den Konsolen sitzen die die Welle 5 mit dem Läuferblechpaket 6 und den Außenlüftern 7 mittels der Lagerschalen 8 tragenden zweiteiligen Lagerkörper 9. Die Lagerkörper 9 bestehen ebenfalls aus Aluminium und haben parallel gerichtete Außenrippen 10 und Innenstege 11 zur Aufnahme der Lagerschalen B. Die in bekannter Weise an den beiden Stirnseiten des Gehäuses angeordneten Außenlüfter 7 sind auf der Welle 5 je zwischen dem Lagerkörper 9 und dem einen Leitkanal 13 für den Außenkühlluftstrom bildenden Gehäuseschild 3 mit einer seitlich von den Schaufeln angeordneten Nabe 15 gelagert. Das Gehäuse hat in der Mitte in bekannter Weise eine radial gerichtete Umlenkwand 14 für die beiden Außenkühlluftströme.The footless rib housing immediately surrounding the stator core 1 2 consists of aluminum and is in a known manner on the double-walled housing shields 3 made of cast iron, which are made of one piece with the consoles 4. On the Consoles sit the shaft 5 with the laminated rotor core 6 and the external fans 7 by means of the bearing shells 8 supporting two-part bearing body 9. The bearing body 9 are also made of aluminum and have parallel outer ribs 10 and inner webs 11 for receiving the bearing shells B. The in a known manner to the External fans 7 arranged on both end faces of the housing are on the shaft 5 each between the bearing body 9 and the one guide channel 13 for the external cooling air flow forming casing shield 3 with a hub arranged laterally from the blades 15 stored. The housing has a radially directed center in a known manner Deflection wall 14 for the two outside cooling air flows.
Infolge der Ausführung des Lagerkörpers aus Leichtmetall und der starken Gliederung der Oberfläche des Lagerkörpers kann auf zusätzliche Kühlmittel im Lagerinneren und auf eine besondere Kühleinrichtung verzichtet werden. Durch den Wegfall einer solchen Kühleinrichtung ergibt sich eine erhebliche Vereinfachung des Aufbaues und des Betriebes der Maschine.As a result of the design of the bearing body made of light metal and the strong Outline of the surface of the bearing body can refer to additional coolant inside the bearing and a special cooling device can be dispensed with. By eliminating one Such a cooling device results in a considerable simplification of the structure and the operation of the machine.
