Stand der TechnikState of technology
Die Erfindung geht aus von einem elektrohydrodynamischen Aggregat nach dem Oberbegriff des Anpsruchs 1.The invention is based on one electrohydrodynamic unit according to the generic term of the claim 1.
Ein solches elektrohydrodynamisches Aggregat ist z.B. eine Fluidpumpe, wie Kühlwasserpumpe, Heizungspumpe, Teichpumpe, Aquariumpumpe, Ölpumpe und dgl., bei der der Fluiddruckerzeuger von einem Pumpenrad gebildet ist, das in einem einen Pumpenraum einschließenden fluidgefüllten Gehäuse angeordnet ist. Bei dieser bekannten Fluidpumpe ist der Elektromotor von dem im Pumpenraum drehenden Pumpenrad getrennt angeordnet. Die Übertragung des Antriebsmoments vom Elektromotor auf das Pumpenrad erfolgt durch ein magnetisches Koppelsystem, das einen gegenüber dem Elektromotor völlig abgeschlossenen Pumpenraum ermöglicht. Diese Pumpenbauweise ist sehr kostenträchtig und erreicht aufgrund der magnetischen Kopplung einen nur relativ geringen Wirkungsgrad.Such an electro-hydrodynamic The aggregate is e.g. a fluid pump, such as a cooling water pump, heating pump, Pond pump, aquarium pump, oil pump and the like, in which the fluid pressure generator is formed by an impeller is arranged in a fluid-filled housing enclosing a pump chamber is. In this known fluid pump, the electric motor is one of those in the pump chamber rotating pump wheel arranged separately. The transfer of the drive torque from the electric motor to the impeller is carried out by a magnetic coupling system that completely closes off the electric motor Pump room enables. This pump design is very expensive and achieved due to the magnetic coupling has a relatively low efficiency.
Ein solches elektrohydrodynamisches Aggregat ist auch ein hydraulischer Aktor oder Steller mit einem hydraulischen Arbeitszylinder, in dem ein den Fluiddruckerzeuger bildender Arbeitskolben axial verschieblich geführt ist. Der Arbeitskolben begrenzt im Arbeitszylinder einen mit einem Einlaß und einem Auslaß versehenen fluidgefüllten Arbeitsraum. Der axiale Hub des Arbeitskolbens wird von dem Elektromotor über ein entsprechendes Getriebe herbeigeführt.Such an electro-hydrodynamic The unit is also a hydraulic actuator or actuator with one hydraulic working cylinder in which the fluid pressure generator forming piston is axially displaceably guided. The working piston delimits one with one inlet and one in the working cylinder Outlet provided fluid-filled Working space. The axial stroke of the working piston is controlled by the electric motor appropriate gear brought about.
Das erfindungsgemäße elektrohydrodynamische Aggregat mit den Merkmalen des Anspruchs 1 hat den Vorteil, daß der Elektromotor und der Fluiddruckerzeuger in einem gemeinsamen, fluidgefüllten Gehäuse untergebracht sind und der Fluiddruckerzeuger ohne nennenswerten Mehraufwand integraler Bestandteil des Elektromotors ist. Der gesamte Wirkungsgrad des Aggregats wird durch Wegfall des üblichen Koppelsystems zwischen Fluiddruckerzeuger und Elektromotor erheblich gesteigert. Die Zahl der benötigten Einzelteile ist drastisch reduziert, was sich vorteilhaft in der Senkung sowohl der Herstellungskosten als auch der Montagekosten niederschlägt.The electrohydrodynamic unit according to the invention with the features of claim 1 has the advantage that the electric motor and the fluid pressure generator housed in a common, fluid-filled housing are an integral part of the fluid pressure generator without any significant additional effort of the electric motor. The overall efficiency of the unit is by eliminating the usual Coupling system between fluid pressure generator and electric motor considerably increased. The number of needed Items is drastically reduced, which is beneficial in the Reduction of both manufacturing costs and assembly costs reflected.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen elektrohydrodynamischen Aggregats möglich.By the measures listed in the other claims are advantageous developments and improvements in the claim 1 specified electrohydrodynamic unit possible.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist das elektrohydrodynamische Aggregat als Fluidpumpe ausgebildet, wobei das Gehäuse mit einem Zulauf und einem Ablauf versehen ist, die auf voneinander abgekehrten Seiten der das Pumpenrad der Fluidpumpe bildenden, schaufelförmigen Radialstreben angeordnet sind, und zwar im Bereich zwischen Rotorkörper und Rotorwelle. Wie bei den bekannten Pumpen ist der zwischen Rotorkörper und Rotorwelle liegende Pumpenraum elektrisch und mechanisch entkoppelt. Koppelelemente zum Ankoppeln des Pumpenrads an den Rotor entfallen. Der Bauraum der erfindungsgemäßen Fluidpumpe ist im Vergleich zu herkömmlichen Fluidpumpen gleicher Leistung drastisch gesenkt und der Wirkungsgrad wesentlich verbessert.According to a preferred embodiment of the Invention is the electrohydrodynamic unit as a fluid pump formed, the housing with an inlet and an outlet is provided on each other opposite sides of the blade-shaped radial struts forming the pump wheel of the fluid pump are arranged, in the area between the rotor body and Rotor shaft. As with the known pumps, that is between the rotor body and the rotor shaft horizontal pump room electrically and mechanically decoupled. coupling elements for coupling the pump wheel to the rotor are not required. The installation space the fluid pump according to the invention is compared to conventional Fluid pumps of the same power are drastically reduced and the efficiency is significant improved.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist das elektrohydrodynamische Aggregat als Aktuator oder Steller zur Erzeugung einer in Achsrichtung gerichteten Stellkraft ausgebildet, wobei die Gehäuseteile des zweiteiligen Gehäuse relativ zueinander axial verschieblich ausgebildet und gegeneinander abgedichtet sind. Bei diesem erfindungsgemäßen Aktuator oder Steller wird die axiale Stellkraft zentral im vollständig fluidgefüllten Gehäuse erzeugt, indem die hydrodynamischen Kräfte und deren Reaktionen an dem von den schaufelförmigen Radialstreben gebildeten Pumpenrad genutzt werden.According to an advantageous embodiment of the Invention is the electrohydrodynamic unit as an actuator or Actuator for generating a positioning force directed in the axial direction formed, the housing parts of the two-part housing axially displaceable relative to each other and against each other are sealed. In this actuator or actuator according to the invention the axial positioning force is generated centrally in the completely fluid-filled housing, by the hydrodynamic forces and their reactions to that formed by the blade-shaped radial struts Pump wheel can be used.
Gemäß einer vorteilhaften Ausführungsform der Erfindung übergreift hierzu der eine Gehäuseteil kappenartig den anderen Gehäuseteil und ist mittels eines Gleitlagers verdrehsicher und axial verschiebbar auf dem anderen Gehäuseteil festgelegt. Zwischen Übergreifungsrand des einen Gehäuseteils und dem anderen Gehäuseteil ist eine umlaufende Dichtung angeordnet. Durch diese konstruktiven Maßnahmen läßt sich der Aktor fertigungstechnisch sehr einfach realisieren.According to an advantageous embodiment of the Invention spills over the one housing part cap-like the other part of the housing and is rotatably and axially displaceable by means of a plain bearing on the other housing part established. Between the overlap of a housing part and the other housing part a circumferential seal is arranged. Through these constructive measures let yourself the actuator is very easy to manufacture.
