Description
Antrieb der Aufspulrolle von Tonbandgeräten.
Zum Antrieb der Aufspulrolle dient eine auf ihrer Achse sitzende Schnur-oder Riemenscheibe$ die über einen Schnur-oder Riementrieb vom Antriebsmotor des Gerätes mit gleichbleibender Geschwindigkeit angetrieben wird und mit der Aufspulrolle mittels einer zwischengeschalteten Kupplung in W8irkverbindung steht. Hierbei übersteigt die Drehzahl der Schnur- oder riemenscheibe die der Abspielgeschwindigkeit des Tonbandes bei leerer Rolle entsprechende Drehzahl der Abspulrolle um ein solches Maß, daß die Mitnahme der Abspulrolle bei jeder Geschwindigkeit gesichert ist.A cord or cord seated on its axis is used to drive the winding roller Belt pulley $ which is driven by a cord or belt from the drive motor of the device is driven at a constant speed and with the winding roller means an intermediate coupling is in active connection. This exceeds the speed of the cord or pulley that of the playback speed of the tape with an empty roll corresponding speed of the unwinding roll to such an extent that the unwinding roll can be taken along at any speed.
Es ist bekannt, die Kupplung zwischen der Abspulrolle und der Schnur-
oder Riemenscheibe als Rutschkupplung auszubilden. Auch wurde bereits vorgeschlagen,
sie als Planetenradkupplung auszugestalten.
Um eine gute und dabei völlig geräuschfreie Reibung zu er-
Nachstehend wird ein Ausführungsbeispiel der Neuerung anhand der Zeichnung beschrieben. In dieser zeigen Fig. 1 einen LängaschnLtt und Fig. 2 eine Draufsicht auf die Neuerung.An exemplary embodiment of the innovation is shown below with reference to the drawing described. 1 shows a longitudinal section and FIG. 2 shows a plan view on the innovation.
Mittels der Halteschraube 1 ist eine, als Bandteller ausgebildete Aufspulrolle 2 drehbar auf einer gerätfesten Drehachse 3 abnehmbar befestigt. Auf dem unteren Wellenstumpf der Aufspulrolle 2 ist eine Riemenscheibe 4 drehbar angeordnet, auf deren mittlerem. ebenen Teil eine Filzscheibe 5 befestigt, z.B. aufgeklebt ist.By means of the retaining screw 1 is a, designed as a band plate Take-up roller 2 rotatably attached to a rotational axis 3 fixed to the device and detachable. on a pulley 4 is rotatably arranged on the lower stub shaft of the winding roller 2, on their middle. flat part a felt disk 5 is attached, e.g. glued on.
Zwischen dem Teller der Aufspulrolle 2, der mit drei Madenschrauben 6 und einem Mitnehmerstift 7 ausgerüstet ist, und der Riemenscheibe 4 ist eine Tellerfeder 8 mit breitem wärte gerichteten Rand eingelegt. In diese greift der Otift ein so daß sie drehfest mit der Aufspulrolle 2 verbunden ist.Between the plate of the take-up reel 2, the one with three grub screws 6 and a driving pin 7, and the pulley 4 is a plate spring 8 inlaid with a wide, pointed edge. The Otift intervenes in this that it is rotatably connected to the winding roller 2.
Mittels der drei auf sie drückenden Madenschrauben 6 kann ihr Federdruck nach Belieben eingestellt werden. Die mit gleichbleibender Geschwindigkeit in nicht dargeatellter Weine vem Antriebsmotor angetriebene Riemenscheibe 4 nimmt mit ihrer Filzscheibe 5 die Tellerfeder 8 und damit die mit dieser drehfest veerbundfene Aufspulrolle 2 sanft und unter sicherem Ausgleich der unterschiedlichen Geschwindigkeit mit. Der Anpreßt druck der Feder 8 ist ohne Abnehmen irgendwelcher Deckplatten, Verschraubungen u. dgl. mittels der von oben leicht zugänglichen Madenschrauben 6 jederzeit leicht regelbar.By means of the three grub screws 6 pressing on them, their spring pressure can be adjusted at will. The constant speed in not dargeatellter Weine vem drive motor driven pulley 4 takes with her Felt washer 5, the plate spring 8 and thus the winding roller that is non-rotatably connected to it 2 gently and safely compensating for the different speeds. The contact pressure of the spring 8 is without removing any cover plates, screw connections and the like easily at any time by means of the grub screws 6, which are easily accessible from above adjustable.
