Description

Es ist bekannt, den Gleichlauf zweier entfernter Achsen, insbesondere von Typendruckern, Bildtelegraphenapparaten u. dgl., dadurch zu erreichen, daß man an den fernen Ort je einen, auf die ungefähre richtige Drehzahl eingeregelten Antriebsmotor vorsieht, welcher durch eine Rutschkupplung mit einer Synchronmaschine verbunden ist.It is known to synchronize two distant axes, in particular type printers, Telegraph apparatus and the like, to be achieved by going to the distant place one Provides drive motor regulated to the approximate correct speed, which is controlled by a Slipping clutch is connected to a synchronous machine.

Diese Synchronmaschinen haben den Zweck,These synchronous machines have the purpose

ίο etwaige Abweichungen von der Solldrehzahl abzugleichen und dadurch die beiden fernen Achsen in dauerndem Gleichlauf zu erhalten.ίο any deviations from the target speed and to keep the two remote axes in constant synchronization.

Um eine gute Synchronisierwirkung beiTo ensure a good synchronizing effect

möglichst kleinem Stromverbrauch zu erzielen, ist es notwendig, die auf die Synchronmaschine fallende Verlustleistung, insbesondere die Reibungsarbeit, gering zu halten; abgesehen von den unvermeidlichen Lagerreibungen und der Kupplungsreibung bei Drehzahlabweichungen ist es vor allem die Reibung der Zuführungsschleifbürsten, die bei den für Fernmeldezwecke verwendeten Maschinen sehr kleiner elektrischer Leistung erhebliche Bedeutung besitzt.To achieve the lowest possible power consumption, it is necessary to use the synchronous machine to keep falling power loss, in particular the work of friction, low; apart from the inevitable bearing friction and clutch friction in the event of speed deviations it is mainly the friction of the feeder brushes that are used for telecommunication purposes The machines used with very low electrical power are of considerable importance.

Zweck der Erfindung ist es, diese schädliche Reibung zu beseitigen; dies geschieht nach der Erfindung beispielsweise dadurch, daß man die Schleifringe AB der Synchronmaschine S statt zwischen Synchronmaschine S und Kupplung R zwischen Antriebsmotor M und Kupplung R anordnet und den Strom der Synchronmaschine S über die Kupplung R zuführt, welche mit zwei isolierten Leitern IK ausgestattet wird; die Anordnung kann z. B. derart getroffen werden, daß auf der treibenden Achse E ein Bürstenträger· mit zwei achsparallelen Schleifbürsten FG angeordnet ist, die mit je einem der beiden Schleifringe A B verbunden sind und auf in eine auf der getriebenen Welle H aufsitzende Kupplungsscheibe eingelassenen, z. B. ringförmigen Leitern IK unter Druck aufliegen; der Kontaktdruck der Bürstenfedern wirkt gleichzeitig als Kupplungsdruck; die ringförmigen Leiter IK in der Kupplungsscheibe sind mit den Wicklungsenden des Synchronmaschinenrotors S leitend verbunden, z. B. durch Drähte, die innerhalb der hohlen getriebenen Achse geführt sind.The purpose of the invention is to eliminate this harmful friction; This is done according to the invention, for example, by arranging the slip rings AB of the synchronous machine S between the drive motor M and the clutch R instead of between the synchronous machine S and the clutch R and supplying the current to the synchronous machine S via the clutch R , which is equipped with two insulated conductors IK ; the arrangement can e.g. B. be made in such a way that a brush holder with two axially parallel grinding brushes FG is arranged on the driving axis E , which are each connected to one of the two slip rings AB and embedded in a clutch disc seated on the driven shaft H, e.g. B. resting ring-shaped conductors IK under pressure; the contact pressure of the brush springs also acts as clutch pressure; the ring-shaped conductors IK in the clutch disc are conductively connected to the winding ends of the synchronous machine rotor S, e.g. B. by wires which are guided within the hollow driven axle.

Durch die erfindungsgemäße Anordnung kann die elektrische Synchronisierleistung wesentlich, bis auf die Hälfte, herabgedrückt werden; dies ist dann besonders wichtig, wenn der Synchronisierstrom, wie üblich, über eine Verstärkeranordnung gewonnen wird, da die notwendige Endleistung für den Preis der Verstärkeranordnung entscheidend ist.Due to the arrangement according to the invention, the electrical synchronizing power can be significantly down to halfway; this is particularly important when the synchronizing current, as usual, via an amplifier arrangement is gained because the necessary final power for the price of the amplifier arrangement is crucial.
