Description

Schmiervorrichtung für das Lager der Ankerwelle magnetelektrischer Kleinmaschinen mit Glockenmagnet, insbesondere Fahrradlichtmaschinen Um das Lager für die Ankerwelle von magnetelektrischen Kleinmaschinen mit Glokkenmagnet zu schmieren, hat man das. Joch des Magneten durchbohrt oder man setzte in dasselbe ein Röhrchen ein, das zum Lager geführt -wurde. Bei Fahrradlichtmaschinen ist zu beachten, daß das einmal geschlossene Maschinengehäuse vom Benutzer der Maschine nicht mehr geöffnet wird. Bei langem Gebrauch macht sich daher ein Mangel all Schmiermitteln im Wellenlager bemerkbar, der nicht behoben werden kann.Lubricating device for the armature shaft bearing magnet-electric Small machines with bell magnets, especially bicycle alternators. Around the warehouse to lubricate the armature shaft of small magneto-electric machines with bell magnet, you have pierced the yoke of the magnet or you put a tube in it one that was led to the camp. With bicycle alternators it should be noted that the machine housing, once closed, can no longer be opened by the user of the machine will. Therefore, if it is used for a long time, there will be a lack of all lubricants in the shaft bearing noticeable that cannot be fixed.

Die Erfindung hat eine Schmiervorrichtung bei solchen magnetelektrischen Kleinmaschinen zum Gegenstand, bei denen ein Glockenmagnet mit aus einzelnen Scheiben bestehendem Joch Anwendung findet. Die Erfindung ist darin zu erblicken, daß aus einer oder mehreren der inneren Jochscheiben Rinnen ausgestanzt sind, die als Vorratsschmierkammer dienen und die zwischen dem Schmierloch in der Lagerbuchse und dem Schmierloch im Jochring einen Verbindungskanal bilden.The invention has a lubricating device in such magneto-electric Small machines on the subject, in which a bell magnet with from individual disks existing yoke is used. The invention can be seen in the fact that from one or more of the inner yoke washers grooves are punched out, which serve as a storage lubrication chamber serve and between the lubrication hole in the bearing bush and the lubrication hole in the Yoke ring form a connecting channel.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel veranschaulicht. Abb. i zeigt einen Längsschnitt durch den Magneten mit einbesetzter Lagerbuchse, Abb. 2 ist ein Schnitt nach der Linie x-x der Abb. i.In the drawing, the invention is illustrated in one embodiment. Fig. I shows a longitudinal section through the magnet with inserted bearing bush, Fig. 2 is a section along the line x-x in Fig. I.

Der Glockenmagnet besteht in bekannter Weise aus den Magnetstäben a, die mit dem aus den Scheiben b, c, d gebildeten Joch durch einen Ring e zusammengehalten werden. In das Joch ist die Lagerbuchse i eingesetzt, die ein seitliches Schmierloch g besitzt. Im Ring e ist ebenfalls ein Schmierloch lt vorgesehen. Die mittlere Jochscheibe c bzw. mehrere innere Scheiben besitzen eine Ausnehmung k, die sich durch den Ansatz! fortsetzt und die beiden Schmierlöcher g und lt verbindet. Die Ausnehmung k kann als enger Kanal vorgesehen sein, der an die Stelle der bisher vorgesehenen Bohrung bzw. eines eingesetzten Röhrchens tritt. Man kann aber auch die Aus.nehmung so verbreitern und unter Umständen durch mehrere Scheiben gehen lassen, so daß ein Vorratsraum für das Schmiermittel geschaffen ist, der für die Lebensdauer der Maschine ausreicht. In diesem Fall wird man das Schmierloch ft im Jochring in bekannter Weise durch Kugelventil oder Schraube o. dgl. abschließen und den Vorratsraum durch einen Saugkörper (Docht, Filz o. dgl.) ausfüllen, von, dem nach und nach eine Abgabe des Schmiermittels an das Lager erfolgt.The bell magnet consists in a known manner of the magnetic bars a, which are held together with the yoke formed from the disks b, c, d by a ring e. The bearing bush i, which has a lateral lubrication hole g, is inserted into the yoke. A lubrication hole is also provided in ring e. The middle yoke disk c or several inner disks have a recess k, which extends through the approach! continues and connects the two lubrication holes g and lt. The recess k can be provided as a narrow channel which takes the place of the previously provided bore or an inserted tube. But you can also widen the recess in this way and, under certain circumstances, allow it to pass through several disks, so that a storage space for the lubricant is created which is sufficient for the service life of the machine. In this case, you will close the lubrication hole ft in the yoke ring in a known manner by means of a ball valve or screw or the like and fill the storage space with an absorbent body (wick, felt or the like), from which the lubricant is gradually dispensed the camp takes place.
