Description

Wechselstrommaschine zum Anbau an Verbrennungsmotoren o. dgl. Es ist bereits bekannt, elektrische Maschinen, deren Welle mit der Kurbelwelle eines Verbrennungsmotors gekuppelt wird, mittels langer, parallel zur Maschinenachse verlaufender Schraubenbolzen an dem Verbrennungsmotor zu befestigen. Bei diesen bekannten Ausführungen handelt es sich um metallene Gehäuse für die Elektromotoren, die eine ausreichende Festigkeit besitzen, um den beim Anziehen der Schraubenbolzen auftretenden Druck aufzunehmen. Es ist zwar auch bekannt, das Gehäuse elektrischer Maschinen, z. B. elektrischer Kleinmotoren, wie sie beispielsweise an Flugzeugmotoren angebracht werden, um Anzeigegeräte zu betätigen, aus Preßstoff herzustellen. Derartige Gehäuse würden beim festen Anziehen der genannten Schraubenbolzen zerplatzen.AC machine for mounting on internal combustion engines or the like. It is already known, electrical machines whose shaft is connected to the crankshaft of an internal combustion engine is coupled by means of long screw bolts that run parallel to the machine axis to attach to the internal combustion engine. In these known designs is These are metal housings for the electric motors that have sufficient strength have to absorb the pressure occurring when tightening the screw bolts. Although it is also known to use the housing of electrical machines, e.g. B. electrical Small engines, such as those attached to aircraft engines, for display devices to operate, made of molded material. Such housings would if tightened firmly of the aforementioned screw bolts burst.

Die Erfindung bezieht sich auf eine Vorrichtung zum Befestigen von Wechselstromerzeugern mit Preßstoffgehäuse und besteht darin, daß die Schraubenbolzen der obengenannten Art von Metallhülsen umgeben sind, die ihrerseits den beim Befestigen der Maschine auftretenden Schraubendruck aufnehmen und vom Gehäuse fernhahen.The invention relates to a device for fastening Alternators with molded casing and consists in that the screw bolts of the type mentioned above are surrounded by metal sleeves, which in turn help when fastening Record the screw pressure occurring on the machine and keep it away from the housing.

In der Zeichnungb ist die Erfindung beispielsweise in einer Ausführungsform veranschaulicht.In the drawing b the invention is for example in one embodiment illustrated.

Sie zeigt einen Längsschnitt durch einen Wechselstromerzeuger, der an einen Verbrennungsmotor, z. B. einem Flugzeugmotor, angeschlossen ist. Darin bezeichnet a das Gehäuse des Verbrennungsmotors. Dieses enthält vier Gewindebohrungen, die zur Aufnahme von Gewindebolzen b dienen. c ist das Gehäuse des Wechselstromerzeugers mit den Deckeln bzw. Lagerschildernd und e; es besteht aus Preßstoff. Letzteres hat bekanntlich den Vorzug, daß das Gehäuse keiner Nachbearbeitung bedarf. Zwischen die Bolzenköpfe f und den Deckehe ist ein Eisenring g gelegt, der das Gehäuse c umfaßt. Die Gewindebolzen b liegen in Metallhülsen h, die an ihren Enden aufgebördelt sind und das Maschinengehäuse c, d mit dem Ring g zusammenhalten. Die Hülsen h' bilden zusammen mit dem Deckelring g ein stabiles Gerippe für den Gehäusekörper und schützen diesen vor Zerstörung, wenn die Bolzen b ins Gehäuse a des Verbrennungsmotors eingeschraubt bzw. fest angezogen werden.It shows a longitudinal section through an alternator connected to an internal combustion engine, e.g. B. an aircraft engine connected. In it, a denotes the housing of the internal combustion engine. This contains four threaded holes that are used to accommodate threaded bolts b. c is the housing of the alternator with the covers or end shields and e; it consists of molded material. The latter is known to have the advantage that the housing does not require any post-processing. Between the bolt heads f and the ceiling an iron ring g is placed, which includes the housing c. The threaded bolts b lie in metal sleeves h, which are flanged at their ends and hold the machine housing c, d together with the ring g. The sleeves h 'together with the cover ring g form a stable framework for the housing body and protect it from destruction when the bolts b are screwed or tightened into the housing a of the internal combustion engine.
