Description
Kleinmaschine für elektrische Taschenlampen. Die Erfindung betrifft eine Kleinmaschine für elektrische Taschenlampen, deren kreisender Dauermagnet aus aneinanderliegenden, durch Federn zusammengehaltenen Teilen besteht. Letztere haben Schlitze, in die mit einem gewissen Spiel feste Führungsdaumen einer auf der Welle sitzenden Scheibe eingreifen. Zufolge dieser Anordnung spreizt die Fliehkraft entgegen der Wirkung der Federn die beweglichen Teile des Magneten auseinander, so daß der Luftraum zwischen den Feld- und Ankerpolen entsprechend der Drehzahl geändert wird. Es zeigen Abb. i und 2 eine Vorder- und Seitenansicht eines zweipoligen, Abb.3 eine Vorderansicht eines vierpoligen Magneten gemäß der Erfindung.Small machine for electric flashlights. The invention relates to a small machine for electric flashlights, whose circling permanent magnet is made contiguous parts held together by springs. The latter have Slots in which, with a certain amount of play, fixed guide thumbs on the shaft the seated disc. As a result of this arrangement, the centrifugal force spreads in the opposite direction the action of the springs separates the moving parts of the magnet, so that the Air space between the field and armature poles is changed according to the speed. It shows Fig. I and 2 a front and side view of a two-pole, Fig.3 a Front view of a four-pole magnet according to the invention.
Nach Abb. i und 2 besteht der Magnet aus zwei Teilen i und ja, deren Pole 2 und 2a parallel der Drehachse 3 umgebogen sind. Diese Teile i und ja liegen längs einer Linie .l aneinander, die durch die Drehachse 3 geht, und sind seitlich zwischen zwei auf Welle 3 aufgekeilten Scheiben 5 und 5° geführt. Die Scheibe 5 hat zwei Daumen 6, welche in Schlitze 7 und 7a eingreifen, die in den Teilen i und ja parallel zu deren Trennungslinie d. angeordnet sind. Federn 8, die in den Punkten 9 und 9a an den Teilen i und ja befestigt sind, halten letztere in der gezeichneten Ruhestellung. Wenn die Drehgeschwindigkeit über ein bestimmtes Maß steigt, spreizt die Fliehkraft die Teile i und ja auseinander, so daß sich der Abstand zwischen den Magnetpolen 2 und 2a und den festen Enden der Ankerkerne selbsttätig in solchem Sinne ändert, daß die induzierte elektromotorische Kraft nachläßt.According to Fig. I and 2, the magnet consists of two parts i and yes, theirs Poles 2 and 2a are bent parallel to the axis of rotation 3. These parts i and yes lie along a line .l to each other, which goes through the axis of rotation 3, and are laterally guided between two disks 5 and 5 ° wedged on shaft 3. The disc 5 has two thumbs 6 which engage in slots 7 and 7a in parts i and yes parallel to their dividing line d. are arranged. Feathers 8 in the points 9 and 9a are attached to parts i and ja, the latter hold in the drawn Rest position. If the turning speed rises above a certain level, it spreads the centrifugal force separates the parts i and yes, so that the distance between the magnetic poles 2 and 2a and the fixed ends of the armature cores automatically in such Meaning changes that the induced electromotive force decreases.
Abb.3 zeigt einen vierpoligen Magneten in Kreuzform. Die Trennungslinie 4 der Teile i und ja geht gleichfalls durch die Achse 3 und teilt den Feldmagneten in zwei Teile, deren Pole entgegengesetzte Polarität haben. Die Schlitze 7 und 7` sind senkrecht zu der Verbindungslinie 4. angeordnet, auf einem der Durchmesser der Triebachse 3. Die Wirkungsweise ist dieselbe, wie vorhin beschrieben.Fig.3 shows a four-pole magnet in a cross shape. The dividing line 4 of the parts i and ja also goes through the axis 3 and divides the field magnet into two parts, the poles of which have opposite polarity. The slots 7 and 7 ' are arranged perpendicular to the connecting line 4., on one of the diameter of the drive axis 3. The mode of operation is the same as described above.
