Description

Patentansprüche: 1. Lagerschild für eine oberflächenbelüftete elektrische Maschine mit geschlossenem Gehäuse, dessen mit dem Gehäuse abschließend verbundene Tragscheibe einen Lagerkopf umgibt, d a d u r c h g e k e n n z e i c h n e t, daß die Tragscheibe eine in Achsrichtung nach außen vorgewölbte Außenringzone (8) mit radialen Innenrippen (9) und radial an diese anschließend eine in Achsrichtung nach innen vorgewölbte Innenringzone (11) mit an dem Lagerkopf (7) angrenzenden radialen Außenrippen (12) aufweist, so daß die Innenrippen (9) vor den benachbarten Ständerwickelköpfen (10), die glatte Innenfläche der Innenringzone (11) vor der benachbarten Stirnseite (13) der Läuferwicklung liegen. Claims: 1. End shield for a surface-ventilated electrical Machine with closed housing, its connected with the housing finally Support washer surrounds a bearing head, which means that the support disk has an outer ring zone (8) bulging outwards in the axial direction radial inner ribs (9) and radially adjoining this one in the axial direction inwardly bulging inner ring zone (11) with radial ones adjoining the bearing head (7) Has outer ribs (12), so that the inner ribs (9) in front of the adjacent stator winding heads (10), the smooth inner surface of the inner ring zone (11) in front of the adjacent end face (13) of the rotor winding.

2. Lagerschild nach Anspruch 1 für die B-Seite der Maschine. vor dem ein Lüfter innerhalb einer Lüfterhaube angeordnet ist, dadurch gekennzeichnet, daß der Lüfter (4) die Außenkühlluft oberhalb der Außenrippen (12) nur über die glatte Außenringzone (8) dem verrippten Umfang des Gehäuses (1) zuführt. 2. End shield according to claim 1 for the B-side of the machine. before which a fan is arranged within a fan cover, characterized in that, that the fan (4) the outside cooling air above the outer ribs (12) only via the smooth outer ring zone (8) feeds the ribbed circumference of the housing (1).

Die Erfindung betrifft ein Lagerschild nach dem Oberbegriff des Patentanspruchs 1. The invention relates to a bearing plate according to the preamble of the patent claim 1.

Die üblichen Lagerschilde dieser Art sind scheiben-oder haubenförmig ausgebildet und hinsichtlich der mechanischen Steifigkeit, der Kühlluftführung auf der Innen- und Außenseite und der Wärmeabfuhr von den Lagerköpfen verbesserungsbedürftig. The usual end shields of this type are disk-shaped or hood-shaped formed and in terms of mechanical rigidity, the cooling air duct the inside and outside and the heat dissipation from the bearing heads in need of improvement.

Der Erfindung liegt die Aufgabe zugrunde, das Strömungsverhalten der Außenkühlluft zu den axialen Gehäuserippen am Umfang des Gehäuses zu verbessern sowie die Entwärmung der Lager über die Lagerköpfe und die sie umgebenden Tragscheiben der Lagerschilde zu intensivieren und die Wärmeaufnahmefähigkeit im Bereich der Ständerwickelköpfe zu erhöhen und die Lagerschilde leicht und formsteif auszubilden. The invention is based on the problem of the flow behavior to improve the outside cooling air to the axial housing ribs on the circumference of the housing as well as the cooling of the bearings via the bearing heads and the supporting disks surrounding them intensify the end shields and the heat absorption capacity in the area of the To increase stator winding heads and to make the end shields light and dimensionally stable.

Die Lösung der Aufgabe gelingt durch die Maßnahmen nach dem Kennzeichen des Patentanspruchs 1. The task is solved by the measures according to the label of claim 1.

Ein Ausführungsbeispiel der Erfindung ist an Hand eines in der Zeichnung teilweise dargestellten Längsschnitts für eine solche Maschine nachfolgend näher erläutert. An embodiment of the invention is based on one in the drawing Partially shown longitudinal section for such a machine in more detail below explained.

Das Gehäuse 1 ist an beiden Stirnseiten durch gleiche Lagerschilde 2 abgeschlossen. Vor dem B-seitigen Lagerschild sitzt am Wellenstumpf 3 ein Lüfter 4 innerhalb einer zu den Gehäuserippen 15 hin offenen Lüfterhaube 5. Das Ständerblechpaket 6 grenzt umfangsseitig unmittelbar an das Gehäuse 1 an. Die Lagerschilde 2 bestehen jeweils aus einer die Lagerköpfe 7 umfassenden Tragscheibe mit einer in Achsrichtung nach außen vorgewölbten Außenringzone 8 mit radialen Innenrippen 9 vor den Ständerwickelköpfen 10 sowie einer radial an die Außenringzone anschließenden, in Achsrichtung nach innen vorgewölbten Innenringzone 11 mit radialen Außenrippen 12, die an die Lagerköpfe 7 angrenzen. Die glatte Innenfläche der Innenringzone liegt jeweils vor der Stirnseite 13 der Läuferwicklung im Läuferblechpaket 14. The housing 1 is supported by the same end shields on both ends 2 completed. A fan is located on the stub shaft 3 in front of the B-side end shield 4 within a fan cover open to the housing ribs 15 5. The stator core 6 directly adjoins the housing 1 on the circumferential side. The end shields 2 exist each of a support disk encompassing the bearing heads 7 with one in the axial direction outwardly bulging outer ring zone 8 with radial inner ribs 9 in front of the stator winding heads 10 and a radially adjoining the outer ring zone, in the axial direction inwardly bulging inner ring zone 11 with radial outer ribs 12, which are attached to the bearing heads 7 adjoin. The smooth inner surface of the inner ring zone lies in front of the end face 13 of the rotor winding in the laminated rotor core 14.

Claims (1)

Der Lüfter 4 bläst die Außenluft ungestört über die glatte Fläche der Außenringzone 8 auf die axialen Gehäuserippen 15 am Gehäuseumfang. Die Außenrippen 12 liegen zwar nicht direkt im Kühlluftstrom, vergrößern aber die wärmeabgebende Oberfläche im Bereich der Lagerköpfe 7 und führen somit zu einer verbesserten Lagerkühlung. Die glatte Innenfläche der Innenringzone 11 nimmt wegen der relativ kleinen Oberfläche die Wärme der Läuferwicklung nur in sehr geringem Maße auf. Dagegen entziehen die Innenrippen 9 die Wärme der Ständerwickelköpfe in hohem Maße. The fan 4 blows the outside air undisturbed over the smooth surface the outer ring zone 8 on the axial housing ribs 15 on the housing circumference. The outer ribs 12 are not directly in the cooling air flow, but increase the heat emitting Surface in the area of the bearing heads 7 and thus lead to improved bearing cooling. The smooth inner surface of the inner ring zone 11 increases because of the relatively small surface the heat of the rotor winding only to a very small extent. On the other hand, they withdraw Inner fins 9 the heat of the stator winding heads to a great extent.
