Abstract

The unit has a housing in which an external rotor motor is arranged and is integrated in reduction gears, where the external rotor motor has a stator (1) and a rotor (2). Gear wheels (3) of the reduction gears are provided in the housing. One of the gear wheels together with the rotor is arranged on a drive shaft (5), and the other gear wheel is arranged on an output shaft (4).

Description

Die Erfindung betrifft eine Antriebseinheit für einen Regelantrieb. Derartige Regelantriebe werden in der Mess-, Steuer- und Regelungstechnik zur Betätigung von Ventilen, Klappen und dergleichen verwendet.The The invention relates to a drive unit for a variable speed drive. such Variable speed drives are used in measurement and control technology for operation used by valves, flaps and the like.

Ein derartiger Regelantrieb besteht im wesentlichen aus einem Elektromotor und einem Getriebe. Der Elektromotor, im wesentlichen aus einem Stator und einem Rotor bestehend, ist regelmäßig außen am Getriebe angeflanscht. Das Getriebe dient zur Untersetzung der Motordrehzahl und weist mindestens eine Antriebswelle und eine Abtriebswelle, sowie Getriebeelemente, wie Zahnräder, die zur Übertragung eines Drehmoments von der Antriebswelle zur Abtriebswelle geeignet sind. Die Abtriebswelle kann in besonderer Ausführung mit einem Hebelarm verbunden sein, dessen Drehbewegung höchstens eine Umdrehung ist und an dem ein hohes Drehmoment abgreifbar ist.One Such control drive consists essentially of an electric motor and a gearbox. The electric motor, essentially a stator and a rotor, is flanged regularly outside the gearbox. The gearbox serves to reduce the engine speed and points at least one drive shaft and an output shaft, and transmission elements, like gears, those for transfer a torque from the drive shaft to the output shaft suitable are. The output shaft can be connected in a special embodiment with a lever arm be whose rotation at most is a turn and on which a high torque can be tapped.

Nachteilig an derartigen bekannten Anordnungen ist, insbesondere bei hohen Untersetzungsverhältnissen, die Vielteiligkeit der Anordnung, der daraus resultierende Raumbedarf und schließlich den Aufwand in der Fertigung und in der Unterhaltung.adversely in such known arrangements, especially at high Reduction ratios, the multiple nature of the arrangement, the resulting space requirements and finally the Effort in manufacturing and entertainment.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Antriebseinheit anzugeben, die bei gleicher Leistung mit weniger Bauteilen auskommt.Of the Invention is therefore the object of a drive unit be specified, which manages with the same power with fewer components.

Erfindungsgemäß wird diese Aufgabe mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den rückbezogenen Ansprüchen angegeben.According to the invention this Task solved with the features of claim 1. advantageous Embodiments of the invention are given in the dependent claims.

Das Wesen der Erfindung besteht in der Verwendung eines Außenläufermotors anstelle des bekannten Elektromotors mit innenliegendem Läufer. Derartige Außenläufermotoren weisen ein hohes Drehmoment bei geringen Drehzahlen auf. Vorteilhafterweise kommt die erfindungsgemäße Antriebseinheit mit einem geringeren Untersetzungsverhältnis zwischen der Antriebswelle und der Abtriebswelle des Getriebes aus. Dementsprechend ist die Anzahl der Bauteile verringert und die Antriebseinheit kommt mit einem geringeren Bauvolumen aus.The Essence of the invention is the use of an external rotor motor instead of the known electric motor with internal rotor. such External rotor motors have a high torque at low speeds. advantageously, comes the drive unit according to the invention with a lower reduction ratio between the drive shaft and the output shaft of the transmission. Accordingly, the Number of components reduced and the drive unit comes with a smaller volume of construction.

Nach einem weiteren Merkmal der Erfindung ist der Außenläufermotor in das Getriebe integriert. Damit ist der außen liegende Läufer gegen unabsichtliche Berührung geschützt.To a further feature of the invention, the external rotor motor is integrated in the transmission. In order to is the outside lying runners against unintentional contact protected.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. In der einzigen Figur ist eine teilweise geschnitten dargestellte Antriebseinheit gezeigt. In einem Gehäuse 6 ist ein Außenläufermotor, bestehend aus einem innenliegendem Stator 1 und einem außenliegenden Läufer 2, angeordnet. In dem Gehäuse 6 sind darüber hinaus Zahnräder 3 eines Untersetzungsgetriebes vorgesehen. Dabei ist ein Zahnrad 3 gemeinsam mit dem Läufer 2 auf einer Antriebswelle 5 angeordnet. Auf einer Abtriebswelle 4 ist ein weiteres Zahnrad angeordnet, das mit dem Zahnrad auf der Antriebswelle 5 in Eingriff stehlt.The invention will be explained in more detail below with reference to an embodiment. In the single figure, a partially cut drive unit is shown. In a housing 6 is an external rotor motor consisting of an internal stator 1 and an outside runner 2 arranged. In the case 6 are also gears 3 a reduction gear provided. There is a gear 3 together with the runner 2 on a drive shaft 5 arranged. On an output shaft 4 Another gear is arranged with the gear on the drive shaft 5 in stealing.
