Description

Bei elektrischen Meßgeräten, beispielsweise Drehzahlgebern, die an einen Flugzeugmotor angeflanscht werden, steht ein äußerst beschränkter Raum zur Verfügung. Die Anbringung erfolgt mittels einer Anschlagplatte, und um beim Anbau und auch notfalls beim Auswechseln der elektrischen Maschine mit den Werkzeugen bequem zu den Befestigungsbolzen zu gelangen, besteht die Erfindung darin, daß das in an sich bekannter Weise einen kreuzförmigen Querschnitt aufweisende Gehäuse mit dem Ständer derart ausgebildet ist, daß zwischen den Kreuzschenkeln an der Anschlagplatte freie Winkelräume verbleiben, die zur Aufnahme der Befestigungsmittel dienen. Weiterhin ist die Erfindung darin zu erblicken, daß in den Kreuzschenkeln des Ständers parallel zu den Schenkelachsen liegende Nuten vorgesehen sind, in die die fertig gewickelten Spulen eingeführt werden.In electrical measuring devices, such as speed sensors, the Flanged to an aircraft engine, there is an extremely limited space available Disposal. The attachment is made by means of a stop plate, and around when mounting and also, if necessary, when changing the electrical machine with the tools easy to get to the fastening bolts, the invention consists in that the in a known manner with a cruciform cross-section having housing the stand is designed such that between the cross legs on the stop plate free angular spaces remain, which are used to accommodate the fastening means. Farther the invention can be seen in the fact that in the cross legs of the stand parallel Grooves lying on the leg axes are provided into which the finished wound Coils are introduced.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in Draufsicht auf einen Querschnitt durch die Maschine dargestellt.In the drawing, an embodiment of the invention is in plan view shown on a cross section through the machine.

Auf die Anschlagplatte a ist das topfförmige Gehäuse b aufgesetzt. Die Anschlagplatte, deren Umfang einer bestimmten Vorschrift entspricht, besitzt die Anschlaglöcher c in den vier Ecken der Platte. Das Gehäuse b hat einen kreuzförmigen Querschnitt und ist derart zur Anschlagplatte a angeordnet, daß die Löcher c in den Winkeln zwischen den Kreuzschenkeln frei zugänglich liegen. Dem OOnerschnitt des Gehäuses ist der Ständer d angepaßt. Die einzelnen Kreuzschenkel besitzen so viel Fleisch, daß die Ständernuten e parallel zur waagerechten bzw. senkrechten Mittelachse der Schenkel angebracht werden können. a Durch 'die erfindungsgemäße Anordnung wird erreicht, daß sich das Gehäuse unmittelbar an die Anschlagplatte anschließen kann. Es wird dadurch eine Raum- Und Materialerspariiis erzielt. Besonders wichtig ist es aber, daß die Ständerspulen mühelos in ihre Nuten eingeführt werden können. Bei den bisher bekannten Kleinmaschinen bedeutet das Einbringen der Spulen eine mühevolle und zeitraubende Arbeit, da immer nur wenig Drähte zugleich in die engen Eingänge der radialen Nuten eingeordnet werden können. Bei der Anordnung nach der Erfindung kann das Spulenpaket als Ganzes in die Nuten eingeschoben werden.The cup-shaped housing b is placed on the stop plate a. The stop plate, the scope of which corresponds to a certain regulation, has the stop holes c in the four corners of the plate. The housing b has a cross-shaped Cross-section and is arranged in such a way to the stop plate a that the holes c in the angles between the cross legs are freely accessible. The OOnschnitt the stand d is adapted to the housing. The individual cross legs have so a lot of meat that the stand slots e parallel to the horizontal or vertical Central axis of the legs can be attached. a By 'the invention Arrangement is achieved that the housing is directly on the stop plate can connect. Thereby a space and material saving is achieved. Particularly it is important, however, that the stator coils are easily inserted into their slots can. In the previously known small machines, this means bringing in the coils a laborious and time-consuming job, as there are always only a few wires in the narrow entrances of the radial grooves can be classified. When arranging according to According to the invention, the coil pack as a whole can be inserted into the grooves.
