PATENTAMT.PATENT OFFICE.
Zur Erzielung von geräuschlos und spielfrei arbeitenden Zahngetrieben werden unter anderem in der Breite geteilte Räder verwendet, deren Teile durch in Richtung^der- Radebene eingebaute Federn derart gegeneinander verspannt werden, daß die Vorderflanken der einen Radhälfte und die Hinterflanken der anderen Radhälfte in der Zahnlücke des Gegenrades zur Anlage kommen.To achieve gear drives that work noiselessly and free of backlash, among other things Wheels divided in width are used, the parts of which go through in the direction of the wheel plane built-in springs are braced against each other in such a way that the leading edges of the one half of the wheel and the rear flanks of the other half of the wheel in the tooth gap of the mating wheel come to the plant.
ίο Erfindungsgemäß soll ein solcher spielfreier Gang dadurch erreicht werden, daß die beiden Radhälften mit ineinandergreifenden .Schrägflächen, kegeligen Stiften, Kugeln o. dgl. versehen sind und durch eine achsial angeordneteίο According to the invention, such should be play-free Gear can be achieved in that the two wheel halves with interlocking .Schlagflächen, Conical pins, balls o. The like. Are provided and axially arranged by an
1S Feder ineinander bzw. gegeneinander gedrückt werden. Auch hierbei braucht wie bei den eingangs erwähnten Rädern von einem Getriebepaar nur das eine Rad geteilt zu werden, oder es wird bei ungeteilten Rädern ein geteiltes Zwischenrad verwendet. Die Erfindung ist auf der Zeichnung dargestellt, und zwar zeigt Fig. ι ein Rad mit Zahnkupplung in Ansicht, teilweise im Schnitt, und im Grundriß und Fig. 2 ein solches mit Kugelkupplung. Das Rad besteht aus den beiden Teilen α und b. Das Teilrad b sitzt fest auf der Welle c und ist an der Teilfläche mit einer Verzahnung d versehen, während das Teilrad a mit einer auf der Welle radial und achsial verschiebbaren Buchse e regelbar verbunden ist. Die Buchsee trägt eine der Verzahnung d entsprechende Verzahnung f. Durch eine auf der Welle c angeordnete Schraubenfeder g werden die Verzahnungen d und f miteinander in Eingriff gehalten. Infolge seiner Verstellbarkeit auf der Buchse e kann dem Teilrad α die zur Behebung jeglichen Spiels erforderliche Verspannung gegeben werden. 1 S springs are pressed into each other or against each other. Here too, as with the wheels mentioned at the outset, only one wheel of a gear pair needs to be divided, or a divided intermediate wheel is used in the case of undivided wheels. The invention is shown in the drawing, namely FIG. 1 shows a wheel with a toothed coupling in a view, partly in section, and in plan and FIG. 2 such a wheel with a ball coupling. The wheel consists of the two parts α and b. The partial wheel b is firmly seated on the shaft c and is provided with a toothing d on the partial surface, while the partial wheel a is controllably connected to a bushing e which can be moved radially and axially on the shaft. The Buchsee carries a toothing f corresponding to the toothing d . The toothings d and f are held in engagement with one another by a helical spring g arranged on the shaft c. As a result of its adjustability on the socket e , the partial wheel α can be given the tension required to eliminate any play.
Beim Auftreten eines stärkeren Zahnes bzw. · beim Eintritt der wechselnden Drehrichtung gleitet dann die Verzahnung f auf der Verzahnung d um das zum Ausgleich nötige Maß aufwärts und geht nach Überwindung des Hindernisses selbsttätig in die Ursprungslage zurück. +5When a stronger tooth appears or when the direction of rotation occurs, the toothing f slides upwards on the toothing d by the amount necessary for compensation and automatically returns to its original position after overcoming the obstacle. +5
In dem Rad nach Fig. 2 ist die Zahnkupplung durchweine Kugelkupplung ersetzt.In the wheel according to Fig. 2, the tooth coupling is replaced by a ball coupling.
