Description
Antriebsvorrichtung für Sprechmaschinen. Die Erfindung bezieht sich auf eine Antriebsvorrichtung für Sprechmaschinen, bei welcher der Plattenteller durch einen Elektromotor unter Vermittlung von ständig in Eingriff gehaltenen Reibrädern auf der Achse des Motors und der Plattentellerachse bewegt wird. Das Wesen der Erfindung besteht darin, daB die Ankerwelle des Elektromotors vermöge ihrer durch Federwirkung herbeigeführten achsialen Verschiebbarkeit den ständigen Eingriff zwischen den Reibrädern aufrechterhält. Auf diese Weise w=ird die Verschiebbarkeit der Ankerwelle des Elektromotors in ihrem festen Gehäuse für den Reibradeingriff nutzbar gemacht.Driving device for speaking machines. The invention relates to on a drive device for speaking machines, in which the turntable by an electric motor with the help of friction wheels that are constantly engaged is moved on the axis of the motor and the turntable axis. The essence of the invention consists in the fact that the armature shaft of the electric motor is due to its spring action brought about axial displaceability the constant engagement between the friction wheels maintains. In this way, the displaceability of the armature shaft of the electric motor becomes made usable in its solid housing for friction engagement.
Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht.The subject matter of the invention is illustrated in the drawing, for example.
Der Elektromotor a besitzt eine achsial verschiebbare Welle b, die von einer Druckfeder c beeinfluBt wird. Das andere Ende der Welle b trägt ein Reibrad d, das durch den Druck der Feder auf die Welle b in Eingriff mit dem Reibrad e auf der Spindel f des Plattentellers gehalten wird.The electric motor a has an axially displaceable shaft b which is influenced by a compression spring c. The other end of the shaft b carries a friction wheel d, which engages with the friction wheel e due to the pressure of the spring on the shaft b the spindle f of the turntable is held.
