Abstract
Description
Gegenstand der Erfindung:Subject of the invention:
Zahnradpumpe mit Jnnenverzahnung und umlaufendem Gehäuse Das Patent ist gekennzeichnet durch: 1. Die Jnnenverzahnung erlaubt, daß die Pumpe direkt am Gehäuse angetrieben werden kann.Gear pump with internal gearing and rotating housing The patent is characterized by: 1. The internal gearing allows the pump to be connected directly to the Housing can be driven.
2. Durch die Jnnenverzahnung läßt sich auf der dichtenden Zahnseite ein Überdeckungsgrad # von über 2 erreichen, was einen besseren Wirkungsgrad ergibt und höhere Drücke zuläßt.2. The internal toothing allows the sealing tooth side achieve a degree of coverage # of over 2, which results in a better degree of efficiency and allows higher pressures.
3. Bei dieser Konstruktion ist es möglich, durch Anfedern der beiden Schalenhälften a u. b eine absolute Dichtheit ( auf der Pumpseite der Zahnräder ) zu erreichen, was ebenfalls einen besseren Wirkungsgrad und höhere Drücke ermöglicht. Dadurch, daß beide Schalenhälften mit dem entsprechenden Betriebsaruck links und rechts belastet sind, ist der Anpreßdruck nur von der Druckfeder abhangiO, sodaß die Reibung auf ein Itinimum herabgesetzt werden kann. Außerdem ist bei dieser Konstruktion kein. Verschleiß möglich, weil die beiden Schalenhälften auch bei Abnützung immer gleichmäßig an die Zahnköpfe anfedern. Durch die Führungsnut wird der Ansaugraum vom Druckraum getrennt.3. With this construction it is possible by springing the two Shell halves a and b an absolute tightness (on the pump side of the gears ), which also enables better efficiency and higher pressures. The fact that both shell halves with the corresponding operating jerk on the left and are loaded on the right, the contact pressure is only dependent on the compression spring, so that the friction can be reduced to an absolute minimum. Also with this construction no. Wear possible because the two shell halves always wear out Spring evenly onto the tooth tips. The suction space becomes through the guide groove separated from the pressure chamber.
4. Nach dem gleichen Prinzip wie in 3. erfolgt die Dichtung nach der Seite. Auch hier wird die Dic.ltscheibe c; über 2 Federn an die Stirnseite der Zahnräder angefedert, mit Druckausgleich von der Rüciseite. Auch hier wird über die Führungsnut der Ansaugraum vom Druckraum getrennt. Der einlaß bzw.4. According to the same principle as in 3. the seal is carried out according to the Page. Here, too, the Dic.lt disc is c; via 2 springs on the face of the gears sprung, with pressure compensation from the back. Here too, the guide groove is used the suction chamber is separated from the pressure chamber. The inlet or
Auslaß erfolgt stirnseitig über den Befestigungsflansch bei d /- e . An diesem ist auch das umlaufende Gehäuse über Wälzlager aufgenommen, während das Jnnenrad ebenfalls wälzgelagert auf einer im Achsabstand exzentrisch gelagerten Welle sich dreht, die in Befestigungsflansch aufgenommen und über einen Pass-Stift gesichert ist. Der Pass-Stift f sichert die Dicht scheibe gegen Verdrehung. The outlet is at the front via the mounting flange at d / - e. The circumferential housing is also held on this via roller bearings, while the inner wheel also rotates on roller bearings on a shaft which is eccentrically mounted at the center distance, which is received in the mounting flange and secured by a dowel pin. The dowel pin f secures the sealing washer against rotation.
Zusammenfassung der aus dieser Konstruktion/ergebenden Vorteile gegenüber den üblichen Ausführungen von Zahnradpumpen: 1. Besserer Wirkungsgrad 2. Erreichung höherer Drucke, als sie bis jetzt bei Zahnradpumpen üblich und erreichbar sind. Summary of the advantages resulting from this construction / compared to the usual designs of gear pumps: 1. Better efficiency 2. Achievement higher pressures than are customary and achievable up to now with gear pumps.
3. Lange Lebensdauer, weil die federnden Lichtschalen und die Dichtscheibe ebenfalls gefedert, jeden entstehenden Verschleiß wieder ausgleichen.3. Long service life because of the resilient light shells and the sealing washer also sprung to compensate for any wear that occurs.
4. Das umlaufende Gehäuse erlaubt einfache Montage und Einbauverhältnisse.4. The surrounding housing allows easy assembly and installation.
