Description
Bei Kleinmotoren, insbesondere Synchronmotoren zum Antrieb von Uhren, Zeitschaltern und Zählern, bietet die Befestigung des Ankers auf der Ankerwelle verschiedene Schwierigkeiten, insbesondere ist die Verschraubung beider mit Rücksicht auf die verhältnismäßig· sehr dünne Welle nur schwer durchzuführen und gibt auch, bei Verwendung keine zuverlässige Verbindung. Gemäß der Erfindung erfolgt die Befestigung der mit der Welle umlaufenden Teile dadurch, daß eine die Welle fest 'umgreifende, d. h. mit geringer Vorspannung aufgezogene Schraubenfeder vorgesehen ist, die mit ihren beiden Enden mit dem auf die Welle aufgesteckten zu befestigenden Teil verbunden und durch Reibung gegen Verdrehung gegenüber der Welle gesichert ist.. Die Feder kann sich, dabei einfach mit ihren Enden in passende Aussparungen des zu befestigenden Teiles einlegen. Bei den Ankern von Kleinmotoren ist es besonders zweckmäßig, die Spiralfeder im Innern der Ankerbuchse anzuordnen. Die Stirnseiten der Buchse dienen dann zur Zentrierung1 des Ankers, während die die Welle fest umgreifende Spiralfeder zur Befestigung der Buchse auf der Welle dient. Eine weitere Verbesserung dieser Anordnung kann dadurch erzielt werden, daß in der Buchse zwischen die Buchsenwandung und die Spiralfeder ein Hohlzylinder eingefügt wird, der das Aufwickeln der Spiralfeder verhindert.In the case of small motors, especially synchronous motors for driving clocks, timers and counters, fastening the armature to the armature shaft presents various difficulties, in particular the screwing of the two is difficult to carry out in view of the relatively very thin shaft and is also not reliable when used Link. According to the invention, the parts rotating with the shaft are fastened in that a helical spring is provided which firmly encompasses the shaft, ie which is pulled up with a slight bias and which is connected at its two ends to the part to be fastened on the shaft and counteracted by friction Rotation with respect to the shaft is secured. The spring can simply insert itself with its ends into suitable recesses in the part to be fastened. In the case of the armatures of small motors, it is particularly useful to arrange the spiral spring inside the armature bushing. The end faces of the bushing then serve to center 1 of the armature, while the spiral spring firmly encompassing the shaft is used to fasten the bushing on the shaft. A further improvement of this arrangement can be achieved in that a hollow cylinder is inserted in the socket between the socket wall and the spiral spring, which cylinder prevents the spiral spring from being wound up.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung schematisch dargestellt. Mit α ist die Ankerwelle bezeichnet; b ist eine Buchse, an der die Ankerscheibe c befestigt ist. Die Buchse δ ist hohl ausgebildet und dient zur Aufnahme der Schraubenfeder d, deren Innendurchmesser etwas Meiner als der Außendurchmesser der Welle α ist, derart, daß sie nach dem Aufschieben die Welle β fest umgreift. Das eine Federende te Hegt in einer Aussparung der Buchse δ, wodurch eine Verdrehung· der Buchse bzw. des Ankers gegenüber der Welle verhindert wird. Die Seitenteile der Buchse dienen zur Zentrierung des Ankers auf der Welle. Bei der Ausführung nach Abb. 1 ist die Schraubenfeder d' mit ihren beiden Enden an der Buchse befestigt, während bei der Ausführung nach Abb. 2 nur ein Ende der Feder im Anker befestigt ist; das andere Ende ist lose. Die Feder ist so gewickelt, daß die Welle α bei Einführung in die Feder d diese etwas auseinanderspreizt, so daß die Welle fest' von der Feder erfaßt wird.Two exemplary embodiments of the invention are shown schematically in the drawing. The armature shaft is denoted by α; b is a bushing to which the armature disk c is attached. The socket δ is hollow and serves to receive the helical spring d, the inside diameter of which is somewhat smaller than the outside diameter of the shaft α , in such a way that it firmly engages around the shaft β after it is pushed on. The one spring end te Hegt δ in a recess of the socket, whereby a rotation of the sleeve · and the anchor prevents relative to the shaft. The side parts of the bushing are used to center the armature on the shaft. In the embodiment according to Fig. 1, the helical spring d 'is fastened with its two ends to the bushing, while in the embodiment according to Fig. 2 only one end of the spring is fastened in the armature; the other end is loose. The spring is wound in such a way that the shaft α spreads it apart when it is inserted into the spring d , so that the shaft is firmly gripped by the spring.
Zur Erleichterung der Montage ist die Ankerbuchse b nach einer Seite offen und wird nach Einführung der Federn vermittels des Stopfens/ verschlossen.To facilitate assembly, the anchor bushing b is open on one side and is closed by means of the plug / after the springs have been inserted.
Um ein Aufwickeln oder ein seitliches Ausbiegen der Spiralfeder zu verhindern, kann entsprechend Abb. 2 zwischen die Buchsenwandung und die Feder ein Hohlkörper £ eingefügt werden.In order to prevent the spiral spring from winding up or bending out to the side, According to Fig. 2, a hollow body £ is inserted between the socket wall and the spring will.
Durch die erfindungsgemäße Anordnung erhält man eine einfache Montage, da jegliche" Verschraubung fortfallen kann, und dabei eine 'elastische, aber feste Verbindung zwischen Anker und Ankerwelle.The arrangement according to the invention results in a simple assembly, since any " Screw connection can be omitted, and thereby an 'elastic, but firm connection between armature and armature shaft.
