Description

AT 000 343 Ul . Die Erfindung bezieht sich auf ein Getriebe in der Art eines Planetengetriebes mit einem Sonnenrad und Plane-tenrädern, die mit einem sie umgebenden Antriebsrad mit Innenverzahnung in Eingriff sind.AT 000 343 Ul. The invention relates to a transmission in the manner of a planetary gear with a sun gear and planetary gears, which are in engagement with a surrounding drive gear with internal teeth.

Aufgabe der Erfindung ist es, ein Getriebe zu schaffen, mit dem eine lineare Bewegung mit hoher Kraft und gleichzeitig hoher Geschwindigkeit gefahren werden kann.The object of the invention is to provide a transmission with which a linear movement can be carried out with high force and at the same time high speed.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, daß das Sonnenrad und die Planetenräder als Muttem ausgebildet sind, die auf Spindeln lagern.The object of the invention is achieved in that the sun gear and the planet gears are designed as mothers, which are mounted on spindles.

Die Verwendüng mehrerer Spindeln anstelle einer Spindel mit größerem Durchmesser bringt überraschenderweise auch einen ökonomischen Vorteil, da die Bearbeitung der Spindeln, insbesondere die Härtung, wesentlich einfacher und somit billiger ist.The use of several spindles instead of a spindle with a larger diameter surprisingly also brings an economic advantage, since the machining of the spindles, in particular the hardening, is much easier and therefore cheaper.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Figuren der Zeichnung eingehend beschrieben.An exemplary embodiment of the invention is described in detail below with reference to the figures in the drawing.

Die Figur der Zeichnung zeigt einen schematischen Radialschnitt durch ein erfindungsgemäßes Getriebe.The figure of the drawing shows a schematic radial section through a transmission according to the invention.

Das erfindungsgemäße Getriebe weist ein Sonnenrad 1 auf, das im Ausführungsbeispiel von vier Planetenrädern 2 umgeben und mit diesen in Eingriff ist. Erfindungsgemäß sind mindestens zwei Planetenräder 2 vorgesehen.The transmission according to the invention has a sun gear 1, which in the exemplary embodiment is surrounded by four planet gears 2 and engages with them. According to the invention, at least two planet gears 2 are provided.

Das Sonnenrad 1 und die Planetenräder 2 sind als Muttem ausgeführt, die auf Spindeln 3 lagern.The sun gear 1 and the planet gears 2 are designed as mutes, which are mounted on spindles 3.

Die Planetenräder 2 weisen wie das Sonnenrad 1 außen einen Zahnkranz 4 auf, mit denen sie mit der Innenver- AT 000 343 Ul zahnung 5 eines sie umgebenden Antriebsrades 6 in Eingriff sind.The planet gears 2, like the sun gear 1, have a ring gear 4 on the outside, with which they mesh with the inner toothing 5 of a drive wheel 6 surrounding them.

Das Antriebsrad 6 weist auch eine Außenverzahnung 7 auf, über die ein Zahnriemen 8 geführt ist, der das Antriebsrad 6 der Abtriebswelle 9 eines Servomotors 10 verbindet.The drive wheel 6 also has an external toothing 7, over which a toothed belt 8 is guided, which connects the drive wheel 6 of the output shaft 9 of a servo motor 10.

Durch Drehung des Antriebsrades 6 werden die Spindeln 3 mit gleicher Geschwindigkeit axial bewegt.By rotating the drive wheel 6, the spindles 3 are moved axially at the same speed.

Um die Reibungsverluste herabzusetzen, ist erfindungsgemäß vorgesehen, daß die Spindeln 3, das Sonnenrad 1 und die Planetenräder 2 als Rollen oder Kugelgewindetriebe ausgeführt sind.In order to reduce the friction losses, the invention provides that the spindles 3, the sun gear 1 and the planet gears 2 are designed as rollers or ball screws.

Das erfindungsgemäße Getriebe ist äußerst vorteilhaft bei Spritzgießmaschinen einsetzbar. So können sich die Spindeln 3 gemeinsam an der bewegbaren Formaufspann-platte abstützen. Die bewegbare Formaufspannplatte kann mittels der Spindeln 3 schnell in die Schließ- oder Offenstellung verfahren werden. Die Spindeln 3 können auch einen sehr hohen Schließdruck aufbringen.The transmission according to the invention can be used extremely advantageously in injection molding machines. So the spindles 3 can be supported together on the movable platen. The movable platen can be moved quickly into the closed or open position by means of the spindles 3. The spindles 3 can also apply a very high closing pressure.

Das Getriebe ist ebenso beim EinspritzZylinder einsetzbar. Die Spindeln 3 können über eine gemeinsame Druckplatte auf die Plastifizierschnecke einwirken und diese verfahren. \The gearbox can also be used with the injection cylinder. The spindles 3 can act on the plasticizing screw via a common pressure plate and move it. \
