Description

Es sind Laufwerke für lbaiidförmige Aufzeichnungsträger bekannt, in denen der konstante Bandvorschub durch ein Rollenpaar bewirkt wird, welches aus einer konstant (z. B. durch Synchroninotor) angetriebenen Rolle und einer Andruckrolle gebildet wird. Zum Einlegen des Bandes wird die Andruckrolle von- der treibenden Rolle abgeschwenkt. Das bedingt wenigstens einen Freiheitsgrad für die Welle der Andruckrolle, damit sie achsparallel zu sich selbst bewegt werden kann. Die Folge davon ist die Gefahr, daß die Achse der Andruckrolle nicht genau parallel zu der der Treibrolle liegt, wodurch ein Winkel zwischen den Mantelflächen der beiden Rollen und damit ein ungleichmäßiger Andruck des Aufzeichnungsbanden bewirkt wird; dadurch wird (las Baud zu einem schrägen Ablauf mit allen seinen nachteiligen Folgen veranlaßt.Drives for lbaiid-shaped recording media are known in which the constant tape feed is effected by a pair of rollers, which consists of a constant (e.g. by synchronous motor) driven roller and a pressure roller is formed. To insert the tape, the pressure roller is released from the driving force Roll swiveled away. That requires at least one degree of freedom for the wave of Pressure roller so that it can be moved axially parallel to itself. The consequence there is the risk that the axis of the pressure roller is not exactly parallel to the the drive roller, creating an angle between the outer surfaces of the two rollers and thus an uneven pressure of the recording tape is effected; through this is (read Baud caused to a sloping process with all its disadvantageous consequences.

Dieser Mangel machte sich in der Praxis sehr störend bemerkbar; er wird erfindungsgeinäli dadurch beseitigt, daß ein oder beide Lager der Rollenwelle so ausgebildet sind, daß die Rollenachse parallel zu einer vorgegebenen Richtung eingestellt werden kann. Dies kann dadurch bewerkstelligt werden, daß ein oder beide Lager der Rollenwelle exzentrisch gefaßt werden. Dadurch wird der Achse der Andruckrolle die Möglichkeit gegeben, alle Stellungen auf einem Kegelmantel einzunehmen, dessen Höhe durch den Abstand der beiden Lager und dessen Basisdurchmesser durch die Exzentrizität bestimmt ist. Diese immerhin noch beschränkten 1VIögliclikeiten werden durch exzentrische Fassung beider Lager in dem Sinne vermehrt, daß die Achse auf den Mantelflächen einer großen Zahl 'verschieden geneigter Kegel liegen kann. Diese erwünschte Vermehrung der Einstellmöglichkeiten stößt in der Praxis aber auf die Schwierigkeit, daß im allgemeinen nur eines der beiden Lager bequem zugänglich ist, während das andere erst nach weitgehender Demontage des Laufwerkes erreicht werden kann. Nach einem weiteren Erfindungsgedanken wird deshalb nur eines der beiden Lager exzentrisch gelagert, wobei aber der Exzenter aus zwei ineinanderliegenden Exzentern besteht. =\ucli hierdurch schafft man sich die Möglichkeit, die Andruckrollenachse auf den Nlantellächen einer Kegelschar wandern zu lassen. Iin allgemeinen wird das jei\eils andere Lager genügend Freiheit bieten, (laß die Achse ihre Taumelbewegung ungehemmt ausführen kann; u. U. kann es aber zweckmäßig sein, die Welle der Rolle nicht durchgehend auszubilden, sondern in zwei Wellenstümpfe zu zerlegen.This deficiency made itself very annoying in practice; he is erfindungsgeinäli eliminated that one or both bearings of the roller shaft are designed so that the roller axis is parallel to a predetermined direction can be adjusted. This can be done by having either or both Bearings of the roller shaft are taken eccentrically. This becomes the axis of the pinch roller given the opportunity to occupy all positions on a cone shell, its Height due to the distance between the two bearings and its base diameter due to the eccentricity is determined. These still limited possibilities are replaced by eccentric ones Version of both camps increased in the sense that the axis on the lateral surfaces a large number of differently inclined cones. This desired increase the setting options encountered in practice on the difficulty that im generally only one of the two camps is conveniently accessible while the other can only be achieved after extensive dismantling of the drive. After a Therefore only one of the two bearings is eccentric stored, but the eccentric consists of two nested eccentrics. = \ ucli this creates the opportunity to move the pressure roller axis to the To let the nlantel surfaces of a cone family wander. In general this will be the case other bearings offer sufficient freedom, (let the axis unrestrained its wobbling motion can perform; Under certain circumstances, however, it can be useful not to go through the shaft of the roll to train, but to dismantle into two stub shafts.
