Description
Um die Doppelschnecken in eine gegenläufig drehende Bewegung zuTo close the twin screws in a counter-rotating motion versetzen, verden dem Antriebsmotor Untersetzungsgetriebe vorge-move, the drive motor is provided with a reduction gear
- Behaltet.- Hold on.
Außerdem reduzieren diese Getriebe die Motordrehzahl und erhöhen das Abtriebsmoment. Während des Betriebes ist mit großen Kräften an den Abtriebswellen zu rechnen.In addition, these gears reduce and increase the engine speed the output torque. During operation, great forces can be expected on the output shafts.
Es sind mehrere Ausführungsformen bekannt, die diese Kräfte in der Verzahnung vermeiden sollen. Bei bereits ausgeführten Extrudergetrieben kämmen die Abtriebsverzahnungen miteinander. Nachteilig bei dieser Ausführung wirkt sich die erforderliche große Zahnbreite hinsichtlich der Durchbiegung der Wellen aus· Da der Achsabstand der Verzahnung vom Schneckendurchmesser abhängig ist, muß in fast allen Fällen mit Hindestzähnezahlen gearbeitet werden.There are several known embodiments that these forces in the Should avoid interlocking. In the case of extruder gears that have already been implemented, the output gears mesh with one another. Disadvantageous with With this design, the required large face width affects the deflection of the shafts · Since the center distance of the Toothing depends on the screw diameter, you have to work with a minimum number of teeth in almost all cases.
Aufgabe der Erfindung ist es, die Lagerung, sowie die Verzahnung so vorteilhaft zu gestalten, daß die vorstehend erwähnten Nachteile bekannter Ausführungsformen vermieden werden.The object of the invention is the storage, as well as the toothing so to make advantageous that the above-mentioned disadvantages of known embodiments are avoided.
Anhand der Zeichnung wird nachstehend ein Ausfuhrungsbeispiel der Erfindung beschrieben.Based on the drawing, an exemplary embodiment of the Invention described.
Von dem Kegelritzel 1, verteilt sich das Drehmoment gegenläufig auf die baiden innenverzahnten Tellerräder 2, durch diese Innenverzahnung werden die Antriebswellen 3, der Schnecken angetrieben. Durch die Drehmomentenverteilung kann die Zahnbreite relativ gering gehalten werden.From the bevel pinion 1, the torque is distributed in opposite directions the inner toothed ring gears 2, the drive shafts 3 of the worms are driven by this internal toothing. By the torque distribution, the tooth width can be kept relatively small.
Die Abtriebswellen 3 sind versetzt angeordnet und duroh Deokel 4 im Gehäuse 5 abgelagert«The output shafts 3 are arranged offset and duroh Deokel 4 deposited in housing 5 "
Auf Grund der versetzten Anordnung kann die Verzahnung im Durchmesser größer ausgeführt werden, die Zahnbreite verringert sich und die Vellendurchbiegung kaun in Grenzen gehalten werden.Due to the offset arrangement, the toothing can be made larger in diameter, the tooth width is reduced and the wave deflection can be kept within limits.
