Die Erfindung betrifft einen Getriebemotor fuer Schneckenextruder mit einem Elektromotor und einer zahngetrieblichen Übersetzung mit einer Abtriebswelle.The The invention relates to a geared motor for screw extruder with an electric motor and a gear ratio with an output shaft.
Derartige Getriebemotoren haben die Aufgabe, die Bewegung von Elektromotoren mit hoher Leistung so zu transformieren, dass die fuer Schneckenextruder notwendigen niedrigen Drehzahlen und hohen Drehmomente aus der zahngetrieblichen Übersetzung entstehen. Ergaenzend kommt die Forderung hinzu, die Baugroesse der Getriebemotoren zu reduzieren, damit die Extruderanlagen moeglichst wenig Produktionsflaeche einnehmen.such Geared motors are responsible for the movement of electric motors with high performance to transform that for screw extruder necessary low speeds and high torques from the gear ratio arise. In addition, the demand is added, the construction process reduce the gear motors, so that the extruder systems as little as possible Occupy production area.
Aus der EP-1182027 A1 ist ein Antrieb fuer einen Schneckenextruder der eingangs genannten Art bekannt. Dabei durchdringt die Abtriebswelle den hohl ausgebildeten Motor und schliesst an der der Extruderschnecke gegenueberliegenden Seite des Getriebemotors mit einem radial ausgreifenden Kragen, der drehfest mit der Abtriebswelle verbunden ist, an den Rotor des Elektromotors an. Dieser Vorschlag verzichtet dezidiert auf ein Übersetzungsgetriebe.Out EP-1182027 A1 is a drive for a screw extruder of known type. The output shaft penetrates the hollow engine and closes on the extruder screw opposite side of the geared motor with a radially ausgreifenden Collar, which is rotatably connected to the output shaft, to the Rotor of the electric motor on. This proposal decidedly waived on a transmission gear.
Die Praxis hat gezeigt, dass fuer eine grosse Zahl von Faellen eine ausreichend kleine Drehzahl und das erforderliche grosse Drehmoment auf dem gezeigten Wege nicht zu erzielen sind.The Practice has shown that for a large number of cases a sufficiently small speed and the required high torque can not be achieved on the way shown.
Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Antrieb der eingangs genannten Art so auszubilden, dass ein ausreichendes Drehmoment und eine ausreichend niedrige Drehzahl erreicht werden koennen.Of the The invention is therefore based on the object, a drive of The type mentioned above in such a way that sufficient torque and a sufficiently low speed can be achieved.
Die Loesung dieser Aufgabe ist im Anspruch 1 wiedergegeben. Die Auswahl eines Planetengetriebes zur Übersetzung der Motordrehzahl und zur Erzielung des erforderlichen Drehmomentes bietet die vorteilhafte Moeglichkeit einer ringfoermigen Ausbildung des Getriebes, so dass die Abtriebswelle durch das Planetengetriebe gesteckt werden kann. Durch die getriebliche Übersetzung koennen die geforderten Parameter Drehzahl und Drehmoment erreicht werden.The Solution of this problem is given in claim 1. The selection a planetary gear for translation the engine speed and to achieve the required torque offers the advantageous possibility of a ringfoermigen training of the transmission, so that the output shaft is inserted through the planetary gear can be. Due to the gear ratio, the required Parameters speed and torque can be achieved.
In Weiterbildung der Erfindung ist vorgesehen, dass als Elektromotor ein Motor mit einer Polzahl ueber sechs vorgesehen ist. Diese langsam laufenden Motoren kommen dem Erfordernis nach einer niedrigen Drehzahl an der Extruderschnecke sehr entgegen und ergaenzen die getriebliche Übersetzung.In Further development of the invention is provided that as an electric motor an engine with a pole number over six is provided. This slowly running engines come the requirement for a low speed on the extruder screw very contrary and complement the gear ratio.
In vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass der Motor als Torque-Motor ausgefuehrt ist. Torque-Motoren sind wegen ihrer moeglichen dreistelligen Polzahl extreme Langsamlaeufer mit grossem Drehmoment und deshalb fuer die erfindungsgemaesse Loesung eine optimale Ergaenzung. Der Torque-Motor ist mit einer Kuehleinrichtung versehen, da die hohe Leistungsdichte sonst zu einem Waermestau mit unzulaessigen Temperaturen im Bereich des Getriebemotors fuehren wuerde.In Advantageous embodiment of the invention is provided that the Motor as a torque motor is executed. Torque motors are because of their possible three-digit Polzahl extreme slow runners with high torque and therefore for the inventive solution an optimal supplement. Of the Torque motor is provided with a cooling device, since the high Power density otherwise to a heat accumulation with inadmissible temperatures in the Range of the gear motor would lead.
Fuer eine bessere Zugaenglichkeit des Planetengetriebes bei Wartung und Reparatur ist in weiterer Ausgestaltung der Erfindung vorgesehen, dass das Planetengetriebe auf der der Extruderseite gegenueberliegenden Seite des Motors angeordnet ist. Außerdem ist die Waermeabfuhr besser zu realisieren.For a better accessibility of the planetary gear in maintenance and Repair is provided in a further embodiment of the invention, that the planetary gear on the opposite side of the extruder Side of the engine is arranged. In addition, the heat removal better to realize.
Nach einer zusaetzlichen Weiterbildung der Erfindung ist vorgesehen, dass der Rotor des Elektromotors an einem Laengsende das Sonnenrad aufweist und der Stator das Hohlrad traegt, waehrend die Abtriebswelle mit dem Steg verbunden ist.To an additional development of the invention is provided that the rotor of the electric motor at a Laengsende the sun gear and the stator carries the ring gear, while the output shaft connected to the dock.
Motor und Getriebe sind auf diese Weise raumsparend ineinander integriert.engine and gearboxes are integrated into each other in a space-saving way.
Eine vorteilhafte Ausgestaltung der Erfindung ist darin zu sehen, dass der Rotor im Bereich seiner Drehachse hohl ausgebildet ist. Im Zusammenwirken mit dem ringfoermig ausgebildeten Planetengetriebe ergibt sich die Moeglichkeit, die Abtriebswelle durch Motor und Getriebe durchzustecken und dadurch an der Abtriebswelle eine ausreichende Stuetzlaenge fuer die Lager einzustellen.A advantageous embodiment of the invention is the fact that the rotor is hollow in the region of its axis of rotation. In cooperation with the ring-shaped planetary gear results in the Possibility to push the output shaft through the engine and transmission and thereby at the output shaft a sufficient Stuetzlaenge to adjust for the bearings.
Ergaenzend wird fuer die konkrete Ausgestaltung der Erfindung vorgeschlagen, dass der Stator des Motors zwei rohrstueckfoermige, konzentrische, ineinander gesteckte Schalen aufweist, von denen die innere die Lager fuer den hohl ausgebildeten Rotor traegt und die aeussere an ihrem Laengsende das Hohlrad des Planetengetriebes traegt, waehrend der Rotor zwischen beiden Schalen dreht. Diese Ausführung des Motors wird auch als „Außenläufer" bezeichnet. Sie zeichnen sich durch ein besonders hohes Drehmoment aus.additional is proposed for the specific embodiment of the invention, that the stator of the engine has two tubular, concentric, has nested bowls, of which the inner the Bearings for the hollow trained rotor carries and the outer at the end of its length the ring gear of the planetary gear is supported, while the Rotor rotates between both shells. This version of the engine will too referred to as "external rotor" are characterized by a particularly high torque.
Kostenmäßig günstiger ist ein sogenannter „Innenlaeufer", bei dem die Lager, die den Rotor tragen, außen auf diesen aufgesetzt sind bzw. diesen einschließen. Das ist der grundsätzliche Aufbau der gebraeuchlichen Elektro-Motoren.Cost-effective cheaper is a so-called "Innenlaeufer", in which the camps, that carry the rotor, outside are attached to this or include this. That's the basic one Construction of customary electric motors.
Bei Torque-Motoren koennen beide Arten, Außenlaeufer und Innenlaeufer in Abhaengigkeit von den Erfordernissen des Anwendungsfalles zum Einsatz kommen. Innenlaeufer werden dann bevorzugt, wenn das geforderte Drehmoment nicht extrem hoch sein muß.For torque motors, both types, outsiders and inner runners can be used depending on the requirements of the application. Inner runners are preferred when the required torque is not extremely high have to be.
Als vorteilhaft erweist sich im Sinne einer Optimierung der Lagerung der Abtriebswelle, dass die Schalen des Stators stirnseitig einen gemeinsamen ringfoermigen Deckel aufweisen, in dem konzentrisch mit den Schalen und dem Rotor ein vorderes Radiallager der Abtriebswelle aufgenommen ist. Damit rueckt das dem Extruder zugewandte vordere Lager der Abtriebswelle an die aeusserste Begrenzung des Getriebemotors.When advantageous proves in terms of optimization of storage the output shaft that the shells of the stator frontally one have common ring-shaped lid, concentric in the with the shells and the rotor a front radial bearing of the output shaft is included. This turns the front facing the extruder Bearing of the output shaft to the outermost limit of the geared motor.
Ein weiterer Vorzug bezueglich der Optimierung der Lagerung der Abtriebswelle wird darin gesehen, dass die hintere Lagerbaugruppe der Abtriebswelle in einem auf das getriebeseitige Ende des Stators aufgesetzten Gehaeuse angeordnet ist. Damit sind die, im wesentlichen zwei, Lagerstellen zur Gestaltung der Lagerung der Abtriebswelle an den Enden des Getriebemotors angeordnet und erlauben so eine optimale Beabstandung der Lagerstellen. Dabei sind in Laengsrichtung der Abtriebswelle der Motor und das Planetengetriebe zwischen deren Lagern angeordnet.One Another advantage with regard to the optimization of the bearing of the output shaft is seen in that the rear bearing assembly of the output shaft in a mounted on the transmission-side end of the stator housing is arranged. These are the, essentially two, bearings for the design of the bearing of the output shaft at the ends of the geared motor arranged and thus allow optimal spacing of the bearings. In this case, in the longitudinal direction of the output shaft of the engine and the Planetary gear arranged between the camps.
Eine Ausgestaltung des erfindungsgemaessen Getriebemotors dergestalt, dass der Motor und die hintere Lagerbaugruppe das Planetengetriebe zwischen sich einschliessen, erlaubt eine Integragtion von Motor und Planetengetriebe.A Embodiment of the invention geared motor such, that the engine and the rear bearing assembly between the planetary gear Include, allows a Integragtion of the engine and planetary gear.
Die gute Zugaenglichkeit der hinteren Lagerbaugruppe der Abtriebswelle erlaubt die Verwendung bewaehrter Lagerelemente, wobei die hintere Lagerbaugruppe ein Axiallager mit Waelzkoerpern mit schraeger Drehachse aufweist, dem Mittel zum Vorspannen des Axiallagers zugeordnet sind.The good accessibility of the rear bearing assembly of the output shaft allows the use of proven bearing elements, with the rear Bearing assembly a thrust bearing with rolling elements with schraeger axis of rotation has, are associated with the means for biasing the thrust bearing.
