Description

Bei Kleinlichtmaschinen, z. B. solchen für Fahr-und Motorräder, ist es gebräuchlich, den im rotierenden Anker erzeugten Strom über einen Schleifring zu führen, von wo ex durch eine federnd angepreßte Kohle zum isolierten Verbraucheranschluß geleitet wird. Der Rückstrom läuft über Masse. Diese Bauweise gibt durch die Abnutzung der Kohle, durch deren Druckempfindlichkeit, die Neigung zu Verschmutzung mit den dadurch verbundenen Störungen und Minderleistungen oft Anlaß zu Beanstandungen oder völligem Versagen.With small alternators, z. B. for bicycles and motorcycles it is common practice to use a slip ring to generate electricity in the rotating armature to lead from where ex by a resiliently pressed carbon to the isolated consumer connection is directed. The return current runs over ground. This construction gives due to the wear and tear the coal, due to its pressure sensitivity, the tendency to pollution with the malfunctions and underperformance associated with this often give rise to complaints or total failure.

Die vorliegende Erfindung beseitigt alle diese Nachteile, ohne einen größeren Kostenaufwand zu bedingen.The present invention overcomes all of these disadvantages, without one to require greater costs.

In der Zeichnung ist als Ausführungsbeispiel eine vierpolige Fahrradlichtmaschine im Axialschnitt gezeigt, bei der der rotierende Anker a mit seiner Welle b zweiseitig, einerseits im Halslagerkörper (Lagerschild) c, andererseits im Scheitel des Magneten d gelagert ist. Halslagerkörper c und Magnet d sind lösbar verbunden. Durch eine Federe wird mittels einer Kugel f die Ankerachse b nach oben gedrückt.In the drawing, a four-pole bicycle alternator is shown in axial section as an exemplary embodiment, in which the rotating armature a with its shaft b is mounted on two sides, on the one hand in the neck bearing body (end shield) c, on the other hand in the vertex of the magnet d. Neck bearing body c and magnet d are releasably connected. A spring e pushes the armature axis b upwards by means of a ball f.

Auf der anderen Seite des Ankers a sitzt auf der Ankerwelle b, von ihr isoliert, aber in. leitender Verhindung mit dem einen Wicklungsende des Ankers a, ein Tragkörper g für das Druckkugellager h, welches über eine Hülse i sich gegen eine aus Isolierstoff bestehende Scheibe k abstützt. Die Hülse i sowie die Scheibe k sind gegenüber dem Halslager ebenfalls elektrisch isoliert.On the other side of the armature a sits on the armature shaft b, isolated from it, but in a conductive connection with one end of the winding of the armature a, a support body g for the thrust ball bearing h, which via a sleeve i against a disk made of insulating material k is supported. The sleeve i and the disk k are also electrically insulated from the neck bearing.

Fürsorglich ist innerhalb der Hülse i eine Feder o untergebracht, welche die stromleitende Berührung sichert, auch für den Fall, daß bei axialem Spiel achsparallel sich auswirkende Stöße oder Erschütterungen die Verbindung zu unterbrechen bestrebt sind. Diese Feder o ist erheblich schwächer als die zentrale Druckfeder e in der Scheitellagerung.Carefully, a spring o is housed inside the sleeve i, which ensures conductive contact, even in the event that there is axial play axially parallel impacts or vibrations to interrupt the connection are striving. This spring o is considerably weaker than the central compression spring e in the vertex position.

Zwischen der Hülse i und der Scheibe k ist ein stromleitender Streifen l angebracht, der zur Stromabnehmerschraube m führt, die isoliert im Halslager c befestigt (eingeschraubt) ist. Der Stromrückfluß verläuft über die Masse bei ii zurück zum Anker a.A current-conducting strip l is attached between the sleeve i and the disk k and leads to the current collector screw m, which is secured (screwed) in an isolated manner in the neck bearing c. The current return flows through the mass at ii back to the armature a.

Auf diese Weise ist die sich rasch abnutzende und bruchempfindliche Kohlebürste vermieden und einwandfreie Stromabnahme erreicht.In this way, the quickly wears out and fragile Carbon brush avoided and perfect current consumption achieved.
