Description
Die Erfindung betrifft eine verstellbare Flügelzellenpumpe gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an adjustable vane pump according to the preamble of claim 1.
Eine verstellbare Flügelzellenpumpe, auch Drehschieberpumpe oder Hydrauli k-pumpe mit variabler Verdrängung genannt, ist beispielsweise aus der
Immer dann, wenn eine Zelle, die durch zwei benachbarte bewegliche Flügel oder Schieber am Rotor in dem ringförmigen Raum zwischen dem Rotor und dem Hubring abgegrenzt wird, von der Saugzone in die Druckzone gelangt, entsteht ein Druckstoß. Diese Druckstöße können hydraulische Pulsation auf der Pumpenförderseite und dadurch Geräusche und Vibrationen verursachen.Whenever a cell, which is delimited by two adjacent movable blades or vanes on the rotor in the annular space between the rotor and the lifting ring, passes from the suction zone into the pressure zone, a pressure surge occurs. These pressure surges can cause hydraulic pulsation on the pump delivery side, causing noise and vibration.
Bekannte allgemeine Maßnahmen zur Druckstoßminderung sind z. B. eine ungerade Anzahl von Flügeln sowie Steuerventile in den Steueröffnungen.Known general measures for pressure surge are z. B. an odd number of wings and control valves in the control ports.
Außerdem sind als spezielle Maßnahme zur Druckstoßminderung teilkreisförmig verlaufende V-förmige Kerben an Saug- und Förderöffnungen bekannt, welche in bestimmten Winkelstellungen des Rotors Überlaufkanäle zwischen benachbarten Zellen bilden, die gerade von der Saugzone zur Druckzone wechseln. Dadurch wird die Druckänderung weniger abrupt und Pulsationen und Lärm auf der Pumpenförderseite werden vermindert.In addition, part-circular V-shaped notches on suction and delivery openings are known as a special measure for pressure surge reduction, which form in certain angular positions of the rotor overflow channels between adjacent cells, which change straight from the suction zone to the pressure zone. As a result, the pressure change becomes less abrupt and pulsations and noise on the pump delivery side are reduced.
Ein derartiger Überlauf des Förderfluides hat jedoch zur Folge, dass der Förderdruck und die Förderleistung der Pumpe vermindert werden.However, such an overflow of the delivery fluid has the consequence that the delivery pressure and the delivery rate of the pump can be reduced.
Die
Der Erfindung liegt die Aufgabe zugrunde, eine verstellbare Flügelzellenpumpe mit Mitteln zur Pulsations- und Lärmminderungseinrichtung zu versehen, welche noch wirksamer sind und die Leistung der Pumpe noch weniger beeinträchtigen.The invention has for its object to provide an adjustable vane pump with means for pulsation and noise reduction device, which are even more effective and affect the performance of the pump even less.
Diese Aufgabe wird gemäß der Erfindung durch eine verstellbare Flügelzellenpumpe mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention by an adjustable vane pump with the features of claim 1.
Die Erfindung beruht auf der Erkenntnis, dass eine verstellbare Flügelzellenpumpe überwiegend in einem ganz bestimmten Drehzahlbereich Pulsationen und Geräusche erzeugt, und nutzt den Umstand aus, dass die Position des Hubrings von der Pumpendrehzahl abhängt.The invention is based on the recognition that an adjustable vane pump generates pulsations and noises predominantly in a very specific speed range, and exploits the fact that the position of the cam ring depends on the pump speed.
Die Erfindung ermöglicht es auf sehr einfache Weise, Pulsationen und Lärm nur in dem bestimmten Drehzahlbereich durch Überlauf des Förderfluides von der Saugzone zur Druckzone zu mindern. Bei niedrigeren oder höheren Drehzahlen, bei denen eine Pulsations- und Geräuschminderung an sich nicht nötig ist, ist der Überlauf nicht wirksam, so dass bei diesen Drehzahlen die Leistung der Pumpe nicht beeinträchtigt wird.The invention makes it possible in a very simple way to reduce pulsations and noise only in the specific speed range by overflow of the conveying fluid from the suction zone to the pressure zone. At lower or higher speeds, where pulsation and noise reduction is not necessary per se, the overflow is not effective, so at these speeds, the performance of the pump is not affected.
D. h., der Überlaufkanal mindert Druckspitzen nicht permanent, wie im Stand der Technik, sondern nur in einem bestimmten Bereich von Stellungen des Hubrings, in welchem Bereich sich die Vertiefungen in der mindestens einen Seitenplatte des Pumpengehäuses sowie in der daran angrenzenden Seitenwand des Hubrings zu dem Überlaufkanal ergänzen. Bei niedrigeren oder höheren Drehzahlen ist der Überlaufkanal unterbrochen, da die genannten Vertiefungen in der entsprechenden Stellung des Hubrings keinen Überlaufkanal zwischen der Saugzone und der Druckzone ausbilden.D. h., The overflow channel does not permanently reduce pressure peaks, as in the prior art, but only in a certain range of positions of the cam ring, in which area the recesses in the at least one side plate of the pump housing and in the adjoining side wall of the cam ring Complement to the overflow channel. At lower or higher speeds, the overflow channel is interrupted, since said depressions in the corresponding position of the cam ring do not form an overflow channel between the suction zone and the pressure zone.
Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.

Innerhalb eines Winkelbereichs von α ± β in Bezug auf die Position des Lochs 6, welcher Winkelbereich einen Übergangsbereich zwischen der Saugzone und der Druckzone der Flügelzellenpumpe einschließt, verlaufen zwei Nuten oder rillenförmige Vertiefungen 7 und 8 in der Seitenplatte 4 des Pumpengehäuses. Jede Vertiefung 7 und 8 hat einen außerhalb des Übergangsbereichs in Richtung auf den Mittelpunkt der Seitenplatte 4 verlaufenden Abschnitt und einen teilkreisförmig um den Mittelpunkt der Seitenplatte 4 herum verlaufenden Abschnitt, der im Wesentlichen innerhalb des Übergangsbereichs verläuft.Within an angular range of α ± β with respect to the position of the
Die in Radialrichtung verlaufenden Abschnitte der Vertiefungen 7 und 8 reichen bis zu einem Punkt auf der Seitenplatte 4, der auf einem Radius liegt, der kleiner als der Radius des Innenumfangs des Hubrings 1 ist. Die teilkreisförmigen Abschnitte der Vertiefungen 7 und 8 haben in Radialrichtung der Seitenplatte 4 einen Abstand voneinander, welcher kleiner ist als die Breite der muldenförmigen Vertiefung 3 im Hubring 1.The radially extending portions of the
Bei einer typischen Seitenplatte 4 mit einem Durchmesser von z. B. 30 mm haben die Vertiefungen 7 und 8 beispielsweise eine Breite und Tiefe von jeweils ca. 1 mm.In a

Man erkennt, dass die muldenförmige Vertiefung 3 im Hubring 1 nur in einer mittleren Position eine Strömungsverbindung zwischen den rillenförmigen Vertiefungen 7 und 8 in der der Seitenplatte 4 des Pumpengehäuses bildet. Da die Stellung des Hubrings 1 wesentlich von der Pumpendrehzahl abhängt, bei unbelasteter Pumpe ausschließlich von der Pumpendrehzahl, entsteht im Wesentlichen nur in einem bestimmten Drehzahlbereich ein Überlaufkanal, der die Saugzone mit der Druckzone verbindet. Durch geeignete Anordnung und Auslegung der Vertiefungen 3, 7 und 8 wird dieser Drehzahlbereich so gewählt, dass die Pumpe möglichst wenig Pulsationen und dadurch Geräusche erzeugt.It can be seen that the trough-

Wahlweise kann auch die andere Seitenplatte des Pumpengehäuses der Flügelzellenpumpe, welche der Seitenplatte 4 gegenüberliegt, wobei sich der Hubring 1 dazwischen befindet, zwei den rillenförmigen Vertiefungen 7 und 8 entsprechende rillenförmige Vertiefungen aufweisen, die auf dieselbe Weise wie oben für die Seitenplatte 4 erläutert mit einer entsprechenden weiteren muldenförmigen Vertiefung in der anderen Seitenwand des Hubrings 1 zusammenarbeiten.Optionally, the other side plate of the pump housing of the vane pump, which faces the

So hat der Hubring 11 am Außenumfang eine Aussparung 12 mit halbkreisförmigem Querschnitt, die an einem nicht gezeigten Zapfen anliegt, der am Pumpengehäuse befestigt ist, und die Seitenplatte 14 enthält mehrere teilkreisförmige Vertiefungen 15 als Förderkanäle für die Hydraulikflüssigkeit sowie ein Loch 16 für den Zapfen.Thus, the
Im Unterschied zu dem ersten Ausführungsbeispiel enthält der Hubring 11 anstelle der einen muldenförmigen Vertiefung 3 des ersten Ausführungsbeispiels zwei rillenförmige Vertiefungen 17 und 18, die jeweils ähnlich geformt und angeordnet sind wie die rillenförmigen Vertiefungen 7 und 8 in der Seitenplatte 4 des ersten Ausführungsbeispiels, hier aber eine U-Form ausbilden, die an ihrem Boden durch eine Lücke unterbrochen ist. D. h., die rillenförmigen Vertiefungen 17 und 18 erstrecken sich in dem Übergangsbereich zwischen der Saugzone und der Druckzone in gleichem Abstand vom Mittelpunkt des Hubrings 11 und mit einem Abstand voneinander um den Mittelpunkt des Hubrings 11 herum und außerhalb des Übergangsbereichs jeweils in Richtung auf den Mittelpunkt des Hubrings 11.In contrast to the first embodiment, the
Außerdem enthält die Seitenplatte 14 des zweiten Ausführungsbeispiels anstelle der zwei rillenförmigen Vertiefungen 7 und 8 des ersten Ausführungsbeispiels nur eine rillenförmige Vertiefung 13, die einen Teilkreis um den Mittelpunkt der Seitenplatte 14 ausbildet und zusammen mit den rillenförmigen Vertiefungen 17 und 18 im Hubring 11 in dem vorbestimmten Bereich von Stellungen des Hubrings 11 einen Überlaufkanal herstellt.In addition, the

Die oben beschriebenen Formen und Anordnungen der Vertiefungen im Hubring und in mindestens einer Seitenplatte der Flügelzellenpumpe, die sich zu einem Überlaufkanal ergänzen, sind nur beispielhaft und können auf vielfältige Arten verändert werden.The above-described forms and arrangements of the recesses in the lifting ring and in at least one side plate of the vane pump, which complement each other to an overflow channel, are only exemplary and can be varied in many ways.
Zum Beispiel könnte man statt der muldenförmigen Vertiefung 3 im Hubring 1 des ersten Ausführungsbeispiels eine teilkreisförmige Vertiefung mit einer ähnlichen Form wie die Vertiefung 17 in der Seitenplatte 14 des zweiten Ausführungsbeispiels vorsehen, und in diesem Fall könnten die teilkreisförmigen und in einem kleinen Abstand zueinander Abschnitte der Vertiefungen 7 und 8 in der Seitenplatte 4 des ersten Ausführungsbeispiels kürzer sein oder ganz wegfallen.For example, instead of the trough-shaped
Oder man könnte die Ausführungsbeispiele 1 und 2 derart kombinieren, dass eine der beiden Mündungen des Überlaufkanals in die Saug- bzw. Druckzone innerhalb der Seitenplatte des Pumpengehäuses verläuft und die andere der beiden Mündungen des Überlaufkanals innerhalb der Seitenwand des Hubrings verläuft.Or you could combine the
Außerdem können in Fällen, in denen es möglicherweise mehrere verschiedene Drehzahlbereiche gibt, in denen Pulsationen und Lärm entstehen, zusätzliche Vertiefungen vorgesehen werden, welche in allen kritischen Drehzahlbereichen Überlaufkanäle ausbilden und auf diese Weise eine Pulsations- und Geräuschminderung in mehreren Drehzahlbereichen bewirken.In addition, in cases where there may be several different speed ranges in which pulsations and noise occur, additional pits may be provided which form overflow channels in all critical speed ranges and thus provide pulsation and noise reduction in multiple speed ranges.
Schließlich könnten wie bereits erwähnt beide Seitenplatten des Pumpengehäuses der Flügelzellenpumpe sowie beide Seitenwände des Hubrings rillenförmige Vertiefungen aufweisen, die sich jeweils zu einem Überlaufkanal vervollständigen.Finally, as already mentioned, both side plates of the pump housing of the vane pump as well as both side walls of the cam ring may have groove-shaped depressions, each of which is completed to form an overflow channel.
