Description

Geigenstand der Erfindung ist die Ausbil dung 'eines Elektromotors, insbesondere Tauichmotors, die unter Verwendung eines einfachen Mantels aus schmiedbarem Rohr, 5 ohne damit eine Vergrößerung des Durchmessers des Motorgehäuses erforderlich zu machen, die Befestigung der Lagerschilide in der richtigen Lage gegenüber dem Ständer ermöglicht.The fiddle of the invention is education dung 'an electric motor, in particular Dew motor, which, using a simple casing made of malleable tubing, 5 without having to increase the diameter of the motor housing make the attachment of the bearing shields in the correct position in relation to the stand enables.

.Tauichmotoren, deren Mantel aus einem schmiedbaren Rohr hergestellt ist, sind zwar bekannt, doch ist letzteres in mehrere Teile unterteilt, um den Ständer in den Mantel einsetzten und auf einen Innenbund des Mantels aufsetzen zu können, da ein ungeteilter Mantel leine beträchtlic'hie und nutzlose Vergrößerung des Manteldurchmessers um mindestens sio viel erfordern würde, -wie nötig ist, um den Ständer durch die lichte Weite der in den Endteilen des Mantels vorgesehenen Fians'chen, an denen die Lagerschilde abgestützt werden, hindurchzustecken. Diese bekannte Bauart bedingt eine ganze Reihe von HerstellungsoperatLonen und eine komplizierte Montage..Tauichmotoren, whose jacket consists of a malleable pipe is known, but the latter is in several parts divided to insert the stand into the coat and to be able to place it on an inner collar of the jacket, as an undivided jacket no considerable and useless magnification the jacket diameter would require at least sio much, -as necessary is to the stand by the inside width of the provided in the end parts of the jacket Fians, on which the end shields are supported, to put through. This well-known Design requires a whole series of manufacturing operations and a complicated one Assembly.

Durch, die erfindungsgemäße Ausführung wird die Herstellung und Montage des Elektromotors wesentlich, vereinfacht. Die Erfindung beruht darin, daß die Lagersrihilde, die mittels ihrer zylindrischen Anaätze im Innern des Gehäusemantels zentriert sind, in der erforderlichen axialen Lage gegenüber dem Ständerblechpaket durch eine innerhalb dies Mantels gelagerte Distanzhülse gehalten und an diese mittels einer in den Mantel eingeschraubten Ringschraube angepreßt werden. Damit wird 'erzielt, daß die Lage der Lagerstohilder gegenüber dem Ständer, die äußerst -wichtig ist, durch die Distanzhülsen genaui begrenzt ist, da sie durch deren Länge allein bestimmt ist. Dabei wird das Festhalten der richtigen Lage sämtlichier Besitandteile des Elektromotors zueinander durch bloß zwei Ringmuittern 'erzielt, so daß die Anzahl der auf großem Durchmesser mit Gewinde versehenen .Teile auf ein Minimum. herabgesetzt ist.By, the embodiment of the invention the manufacture and assembly of the electric motor is significantly simplified. The invention is based on the fact that the Lagersrihilde, which by means of their cylindrical indentations inside of the housing shell are centered in the required axial position relative to the Stator core held by a spacer sleeve mounted within this jacket and be pressed against this by means of an eyebolt screwed into the jacket. This is achieved 'that the position of the bearing stalls relative to the stand, the It is extremely important to be limited by the spacer sleeves, as they are due to their length is determined alone. It is important to keep the correct position of all items of the electric motor to each other by just two ring muittern 'achieved so that the number large diameter threaded parts to a minimum. degraded is.

In der Zeichnung ist die Erfindung in den Abb. i, 2 und 3 beispielsweise veranschaulicht. Die Abb. 1 ist ein teilweiser Längsschnitt durch den Motor, die Abb. 2 ein. Querschnitt durch den Motor mit zwei bekannten Ausführungsarten der Zentrierrippen, und die Abb. 3 zeigt eine Einzelheit der Mantelauisbildung in einem Teüliängsschnitt.In the drawing, the invention is illustrated in FIGS. 1, 2 and 3 by way of example. Fig. 1 is a partial longitudinal section through the engine, Fig. 2 a. Cross-section through the engine with two known types of centering ribs, and Fig. 3 shows a detail of the shell formation in a partial longitudinal section.

Der Elektromotor, sonst von bekannter Bauart, besteht aus dem in einem Mantel 2 gelagerten Ständerblechpaket 1 und aus den die Welle nebst dem Läufer tragenden Lager Schilden 3. In dem Mantel 2 sind hierbei innen ;niedrige Zentrierrippen 4 vorgesehen, welche in der Nähe der Mantelsiirnen enden. Diese Rippen dienen in bekannter Weise zum Zentrieren des Ständerblechpaketes 1 und zum Zentrieren der Lagerschilde 3 sowie in bekannter Weise zur Bildung Bacher Kanäle 5 zwisichen dem Ständerblechpaket und dem Mantel, durch welche ein Kühlmittel strömen und so das Ständerblechpaket außen kühlen kann.The electric motor, otherwise of a known type, consists of the one in a jacket 2 supported stator core 1 and from the bearing carrying the shaft and the rotor Shields 3. In the jacket 2, low centering ribs 4 are provided on the inside, which end near the cloak sirnen. These ribs are used in a known manner for centering the stator core 1 and for centering the end shields 3 as well as in known way to form Bacher channels 5 between the stator core and the jacket, through which a coolant flows and so the stator core on the outside can cool.

Die LagiersChilde sind mittels eines zylinderfÖMuigen Ansatzes 6 an den Rippen 4 geführt, und ihre erforderliche Lage zum Ständerblechpaket· ist durch Distanzhülsen 7 festgelegt, welche sich an den Stirnflächen des Ständerblechpaketes abstützen und gegen diese mit Ringschrauben 8 verspannt werden.The LagiersChilde are by means of a cylindrical Extension 6 is guided on the ribs 4, and their required position relative to the stator core is through spacer sleeves 7 determined which are supported on the end faces of the stator core and against these are clamped with eye bolts 8.
