Description

Ton einem Motor angetriebene Zahnradpumpe für kleine , Leistungen Inge-Physt Harry Thalheim Bschwegee Âugustastr. 58 Fürkleine Wasserpumpen mit Förder-Zahnrädern ans Eunststoff die an einem Motor angeflanscht sind, war es gebräuchlich, den Motorzapfen mit einer flachen Zunge zu versehen, die in eine Vertiefung der Nabe des einen Pumpenzahnrades eingriff und so die Drehung der Motorwlle auf. das eine der beiden Pumpenzahnräder übertrog. Die Naben der beiden Zahnräder waren gleichzeitig deren Achsstummel, mit denen sie gelagert waren. Ton a motor driven gear pump for small ones , Services Inge-Physt Harry Thalheim Bschwegee Augustastr. 58 For small water pumps with delivery gears to the plastic are flanged to a motor, it was customary to provide the motor journal with a flat tongue, which engages in a recess in the hub of one of the pump gearwheels and thus prevents the motor shaft from rotating. that overran one of the two pump gears. The hubs of the two gears were also their stub axles with which they were mounted.

Der wesentlichste Mangel dieser Konstruktion war die Schwierige keit, die Mitteh von Motorwelle und Zahnrad genau in Ubereinstim- mung zu bringen. Schon die praktisch unvermeidlichen geringen Ab. weichungen hatten Klemmungen zur Folge, die der schwache Motor nicht Überwinden konnte. Hinzu kamen umiberwindliohe Reibungen der Naben in deren Lagerbohrungen, wenn die Passung etwas zu eng war. Der Abrieb bildete mit dem Wasser zusammen einen kommenden - DiebeschriebenenMängelwerdenneuerungsgemaßdadurchvermieden daß die Motorwelle mit der Zahnradpumpe gekuppelt ist durch eine flache Lamelle, die einerseits in einen Schlitz. desNotorjsapfens andererseits in einen Durchbruch des einen Bumpenrades eingreift und daß das Pumpenradpaar keine Naben, Achsen oder der. aufweist, sondern am Außenumfang in der Radkammer geführt ist. ) Ein Ausfuhrungsbeispiel der Neuerung ist in den Abb't und 2 der Zeichnung dargestellt. Abb 1 zeigt einen waagerechten Schnitt nach der Linie A-B der Anordnung der Abb. 2 Abb. 2 zeigt eine Seitensicht der Pumpe teilweise im senkrechten Schnitt. The most important shortcoming of this design was the difficulty in precisely matching the center of the motor shaft and gearwheel. to bring up. Even the practically inevitable minor ab. Deviations resulted in jamming that the weak engine could not overcome. In addition, there was excessive friction of the hubs in their bearing bores if the fit was a bit too tight was. The abrasion formed a coming one with the water - As a result, the described deficiencies are avoided that the motor shaft is coupled to the gear pump by a flat lamella, the one hand in a slot. desNotorjsapfens on the other hand, engages in a breakthrough in a pump gear and that the pair of impellers has no hubs, axles or the. having, but is guided on the outer circumference in the wheel chamber. ) An exemplary embodiment of the innovation is in the Abb't and 2 of the Drawing shown. Fig 1 shows a horizontal section along the line AB of Arrangement of Fig. 2 Fig. 2 shows a side view of the pump, partially vertical Cut.

Der Motor ist mit 1 bezeichnete sein Achszapfen mit 2. @er Achszapfen ist mit einem diametralen Schlitz 3 versehen. In dem Pumpengehäuse 4 sind die beiden Förderzahnräder 5 und 6 gelagerte ihre Zähne sind mit 7 bezeichnete Beide Rader 5 us-d 6 haben keine Naben bzw » Achsatummel, sonder-n sind am Außenomfang geführte wo sie die Radkammer ohnehin so weit ausfüllen müssen, daß kein Zurückströmen der Förderflüssigkeit mtlglich ist. The motor is marked with 1 its stub axle with 2. @er axle journal is provided with a diametrical slot 3. In the pump housing 4, the two feed gears 5 and 6 are their supported Teeth are marked 7. Both wheels 5 us-d 6 have none Hubs or »Achsatummel, special-n are guided on the outer rim where they have to fill the wheel chamber so far anyway that no backflow of the pumped liquid is possible.

Das Rad 5 hat einen ovalen Durchbruch 81 in welchen eine flache Lamelle 9 eingreift und die Drehungen der Motorwelle auf das Zahnradpaar 5, 6 überträgt. Schutzansprüche: 1. Von einem Motor angetriebenen Zahnradpumpe für kleine Leistungen, dadurch gekennzeichnet, daß die Motorwelle (2) mit der Zahnradpumpe (5, 6) gekuppelt ist durch eine flache Lamelle (9), die einerseits in einen Schlitz (3) des Motorzapfens (2), andererseits in einen Durchbruch (8) des einen Pumpenrades (5), eingreift ;.The wheel 5 has an oval opening 81 in which a flat lamella 9 engages and transmits the rotations of the motor shaft to the gear pair 5, 6. Protection claims: 1. Gear pump driven by a motor for small outputs, characterized in that the motor shaft (2) is coupled to the gear pump (5, 6) is through a flat lamella (9), which on one side in a slot (3) of the motor journal (2), on the other hand, engages in an opening (8) of one pump wheel (5);
