Abstract
Description
Die Erfindung betrifft Zahnradölpumpen mit veränderlichen Fördermengen, insbesondere Außenzahnrad-Regelölpumpen für die Schmierölversorgung von Verbrennungsmotoren. Sie stellen automatisch entsprechend der Auslegung ihrer Regelung die Fördermenge bzw. auch den Förderdruck auf den Bedarf ihres mit hydraulischer Leistung zu versorgenden Verbrauchers ein und erzielen damit eine reduzierte Pumpenantriebsleistung.The Invention relates to gear oil pumps with changeable Flow rates, in particular external gear control oil pumps for the Oil supply of internal combustion engines. They automatically set according to the Interpretation of their scheme the flow rate or also the delivery pressure to meet the needs of their with hydraulic power Consumers and thus achieve a reduced pump drive power.

Die Auslegung der Fördermenge einer Ölpumpe ist vom Bedarf an Förderöl eines beispielsweise zu versorgenden Verbrennungsmotors abhängig. Eine Erhöhung der Fördermenge ist bei vorgegebener Antriebsübersetzung nur durch entsprechend veränderte Förderzahnräder möglich, beispielsweise durch Zahnrad-Verlängerung, Zahnrad-Durchmesservergrößerung oder auch durch eine Vergrößerung des Zahnmoduls. Entsprechend einer vorzunehmenden Änderung der Förderzahnräder ist dann deren Umgebung anzupassen, wie das Ölpumpengehäuse und bei Regelölpumpen auch die Verschiebeeinheit incl. Regelung.The Design of the flow rate an oil pump is one of the need for promotional oil For example, to be supplied combustion engine dependent. A increase the flow rate is at a given drive ratio only by appropriately changed Conveyor gears possible, for example by Gear extension, Gear diameter enlargement or also by an enlargement of the Tooth module. According to a change to be made the conveyor gears is then adjust their environment, such as the oil pump housing and in control oil pumps also the shift unit incl. regulation.

Der Erfindung liegt die Aufgabe zugrunde, für Außenzahnrad-Regelölpumpen eine einfache Fördermengenerhöhung ohne wesentlichen Zusatzaufwand zu realisieren.Of the Invention is based on the object for external gear oil pumps a simple delivery quantity increase without substantial additional expense to realize.
Diese Aufgabe wird erfindungsgemäß entsprechend Anspruch 1 in vorteilhafter Weise dadurch gelöst, dass ausgehend von einer einstufigen Außenzahnrad-Regelölpumpe durch ein Hinzufügen eines dritten Förderzahnrades die Fördermenge verdoppelt wird, ohne dass die Verschiebeeinheit und deren Regelung nennenswert verändert werden müssen.These Task is according to the invention accordingly Claim 1 solved in an advantageous manner that, starting from a single stage external gear control oil pump an addition a third conveyor gear the flow rate is doubled without the displacement unit and its regulation changed significantly Need to become.
