Description

Elektrische Kleinmaschine für Fahrzeugbeleuchtung o. dgl. Es ist bei Beleuchtungskleinmaschinen bereits vorgeschlagen worden, die permanenten Feldmagnete parallel zur Welle auf einem mit ihr 'gleichachsigen Halter zu lagern. In gewissen Ausführungen sind auch die Dauermagnete durch parallel zur Achse sich erstreckende Vorsprünge des Halters in ihrer Eigenlage gesichert.Small electric machine for vehicle lighting or the like. It is at Small lighting machines have already been proposed to use permanent field magnets parallel to the shaft on a holder coaxial with it. In certain Designs are also the permanent magnets by extending parallel to the axis Projections of the holder secured in their own position.

Gegenstand der Erfindung ist eine elektrische Kleinmaschine für Fahrzeugbeletichtung o. dg1. mit achsparallelen, permanenten Feldmagneten, welche dadurch gekennzeichnet ist, daß das innere, zur Stützung der Magnetschenkel dienende Ankerlager aus unmagnetisierbarem Material zwischen diese Magnetschenkel sich einschiebende, gleichfalls unmagnetisierbare Arme aufweist, deren Stirnenden durch Schrauben o. dgl. fest mit der das äußere Ankerlager enthaltenden Büchse verbunden sind, und daß durch Schrauben, welche in Löcher des inneren Lagers greifen, das die Magnete an letzteres anpressende Maschinengehäuse fest an die Büchse gedrückt wird.The invention relates to a small electrical machine for vehicle lighting O. dg1. with axially parallel, permanent field magnets, which are characterized by this is that the inner armature bearing serving to support the magnet legs is made of non-magnetizable Material sliding between these magnetic legs, likewise non-magnetizable Has arms, the ends of which by screws o. The like. Firmly with the outer Armature bearing containing bush are connected, and that by screws, which in Grab the holes in the inner bearing that presses the magnets against the machine housing is pressed firmly against the sleeve.

In beiliegender Zeichnung ist ein Ausführungsbeispiel einer Maschine gemäß der Erfindung dargestellt.In the accompanying drawing is an embodiment of a machine shown according to the invention.

Abb. i stellt einen Achsialschnitt dar und Abb.2 ein Schaubild eines ringförmigen Halters, wie er oben erwähnt wurde.Fig. I represents an axial section and Fig. 2 a diagram of a annular holder as mentioned above.

Abb.3 ist ein Schaubild eines der zur Verwendung gelangenden Magneten.Figure 3 is a diagram of one of the magnets that can be used.

In einer Verlängerung der Fußplatte 1 der Maschine ist ein Kugellager 2 angeordnet zur Unterstützung des einen Endes der Motorwelle 3. Auf dieser Welle sitzen die Stromabnehmerringe q. und 5 fest. Während Ring 5 mit dem Maschinenkörper leitend verbunden ist, ist der andere an einer isolierten Bürste 6 angeschlossen, von wo der Strom zu einem der Lampenpole geführt wird. Das innere Wellenende des Ankers 7 dreht sich in einem im ringförmigen Halter 9 gelagerten, aus nichtmagnetisierbarem Metall, wie z. B. Aluminium oder einer Legierung desselben, bestehenden Kugellager B. Dieser ringförmige Halter g besitzt seitliche, parallel zur Ankerwelle verlaufende Verlängerungen io, welche die Lage des Halters 9 bestimmen und ebenso auch den Abstand der leicht gewölbten Hufeisenmagnete i i, deren zwei vorhanden sind. Diese Magnete stützen sich, wie aus den Abb. 2 und 3 hervorgeht, auf den Halter 9, wobei eine der Verlängerungen io je die beiden Magnetschenkel voneinander trennt. In diesen Verlängerungen io befinden sich die mit Muttergewinde versehenen Löcher i2 für die Befestigungsschrauben 13, deren Köpfe auf der Vorderseite der Fußplatte eingelassen sind. Auf diese Weise ist die Fußplatte in kräftiger Weise mit dem Halter verbunden, und die beiden Ankerlager werden durch die Verlängerungen io auf einem bestimmten Abstand festgehalten.In an extension of the base plate 1 of the machine is a ball bearing 2 arranged to support one end of the motor shaft 3. On this shaft the current collector rings are seated q. and 5 fixed. While ring 5 with the machine body is conductively connected, the other is connected to an insulated brush 6, from where the current is led to one of the lamp poles. The inner shaft end of the Armature 7 rotates in a mounted in the ring-shaped holder 9, made of non-magnetizable Metal, such as B. aluminum or an alloy of the same, existing ball bearings B. This annular holder g has lateral, parallel to the armature shaft Extensions io, which determine the position of the holder 9 and also the distance the slightly curved horseshoe magnets i i, two of which are present. These magnets are based, as can be seen from Figs. 2 and 3, on the holder 9, with a the extensions io each separates the two magnetic legs from each other. In these Extensions io are the threaded holes i2 for the Fastening screws 13, the heads of which are embedded on the front of the footplate are. In this way, the footplate is firmly attached to the holder, and the two anchor bearings are on a given by the extensions io Distance kept.

Auf der den Verlängerungen io entgegengesetzten Seite des Halters 9 befinden sich die Löcher mit Muttergewinde für die langen Zugschrauben 1q., deren Köpfe von außen an der aus nichtmagnetisierbarem Metall bestehenden Stirnplatte 15 einer Verschalung anliegen, deren zylindrischer Teil den Durchmesser des um die beiden Magnetdicken vermehrten Durchmessers des Halters besitzt und sich gegen einen Ansatz 16 der Fußplatte i stützt. Werden die Schrauben 14 angezogen, so übt diese Platte einen Druck aus auf das den Polen 17 entgegengesetzte Ende der Magnete und hält diese Magnete im Gleichgewicht auf dem Halter 9, indem sie sie gegen die Fußplatte i anpreßt. Der Ansatz 16 verhindert die Magnete zu kippen und hält deren Pole auf dem richtigen Abstand vom Anker, indem er den Luftspalt bestimmt. - Diese Anordnung gestattet, nach der Härtung roh belassene Magnete zu verwenden und die der Magnetisierung nicht zuträgliche spätere Bearbeitung zu vermeiden. Es genügt, die Schrauben 14 auszuschrauben, um die Verschalung und die Magnete herauszunehmen und so den ganzen mechanischen und elektrischen Teil der Maschine freizulegen.On the opposite side of the holder to the extensions 9 are the holes with nut threads for the long lag screws 1q., Whose Heads from the outside on the end plate made of non-magnetizable metal 15 abut a formwork, the cylindrical part of which has the diameter of the has both magnet thicknesses increased diameter of the holder and against one Approach 16 of the footplate i supports. If the screws 14 are tightened, this exercises Plate exerts a pressure on the end of the magnets and opposite the poles 17 keeps these magnets in balance on the holder 9 by pressing them against the footplate i is pressing. The approach 16 prevents the magnets from tilting and holds their poles the correct distance from the anchor by determining the air gap. - This arrangement allows the use of magnets left raw after hardening and those of magnetization to avoid unsuitable later processing. Suffice it to remove the screws 14 unscrew to take out the casing and the magnets and so the whole thing to expose mechanical and electrical parts of the machine.
