Description

Die Erfindung betrifft ein Tauchmotorpumpenaggregat gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a submersible pump assembly according to the preamble of the main claim.

Derartige Tauchmotorpumpenaggregate werden zur Förderung großer Flüssigkeitsmengen bei geringen Förderhöhen verwendet. Um die für die Anwendung findenden Axialpropeller nötigen Drehzahlen zu erlangen, ist die Verwendung von Untersetzungsgetrieben zwischen Antriebsmotor und Axialpropeller bei Pumpen mit niedrigen Drehzahlen sinnvoll. Hierdurch kann auf den Einsatz von vielpoligen, damit langsam laufenden, aber im Durchmesser großen Antriebsmotoren verzichtet werden. Mit Hilfe des Untersetzungsgetriebes ist es möglich, die in wesentlich größeren Stückzahlen auf dem Markt befindlichen niederpoligen, hochtourigen und preiswerteren Antriebsmotoren Anwendung finden zu lassen. Die Verwendung von Untersetzungsgetrieben erfordert jedoch einen erheblichen Aufwand bezüglich der Lagerung von Pumpenwelle, Antriebswelle und der Getriebeteile.Submersible pump units of this type are used to deliver large quantities of liquid at low delivery heights. In order to achieve the speeds required for the axial propellers to be used, it is advisable to use reduction gears between the drive motor and the axial propeller in pumps with low speeds. This makes it possible to dispense with the use of multi-pole, thus slow-running, but large-diameter drive motors. With the help of Untersetzungsgetrieb e s, it is possible to find the present in much larger quantities in the market down pole, high-speed and cheaper drive engines. The use of reduction gears, however, requires considerable effort with regard to the bearing of the pump shaft, drive shaft and the gear parts.

Der Erfindung liegt daher die Aufgabe zugrunde, für ein kompaktes Tauchmotorpumpenaggregat eine wenig aufwendige, statisch bestimmte Lagerung zu entwickeln. Die Lösung dieser Aufgabe erfolgt gemäß dem kennzeichnenden Teil des Hauptanspruches. Mittels dieser Lösung ist es möglich geworden, die Pumpenwelle mit nur einem Lager innerhalb des Pumpengehäuses anzuordnen und infolge der biegemomentübertragenden Kupplung zwischen Pumpenwelle und Abtriebswelle des Planetengetriebes das zweite Pumpenwellenlager durch das Planetengetriebegehäuse zu bilden. Da die Planetengetriebe üblicherweise eine Vielzahl von Lagerungen innerhalb ihres Gehäuses aufweisen, können die auf die Pumpenwelle einwirkenden Kräfte übernommen und auf das Planetengetriebegehäuse geleitet werden. Die aus Pumpenwelle und Planetengetriebe gebildete bauliche Einheit weist somit ein Festlager innerhalb des Pumpengehäuses und ein Loslager in Form des Planetengetriebegehäuses auf.The invention is therefore based on the object of developing an inexpensive, statically determined bearing for a compact submersible pump unit. This object is achieved in accordance with the characterizing part of the main claim. By means of this solution it has become possible to arrange the pump shaft with only one bearing within the pump housing and as a result of the bending torque transmitting coupling between the pump shaft and output shaft of the planetary gear to form the second pump shaft bearing through the planetary gear housing. Since the planetary gears usually have a large number of bearings within their housing, the forces acting on the pump shaft can be taken over and directed to the planetary gear housing. The structural unit formed from the pump shaft and planetary gear thus has a fixed bearing within the pump housing and a floating bearing in the form of the planetary gear housing.

Eine Ausgestaltung der Erfindung sieht vor, daß der Antriebsmotor unter Zwischenschaltung einer flexiblen Kupplung mit der Antriebswelle des Planetengetriebes verbunden ist. Damit wird eine statisch unbestimmte Lagerung innerhalb des gesamten Aggregates ausgeschlossen.An embodiment of the invention provides that the drive motor is connected to the drive shaft of the planetary gear with the interposition of a flexible coupling. Static undetermined storage within the entire unit is thus excluded.

Eine andere Ausgestaltung der Erfindung sieht vor, daß der Antriebsmotor direkt mit dem Planetengetriebegehäuse und dessen Antriebswelle verbunden ist oder mit dem stillstehenden Hohlrad und der Antriebswelle des Planetengetriebes verbunden ist. Mittels dieser Maßnahme kann die Baugröße des Aggregates wesentlich verkleinert werden und z.B. bei Verwendung eines hydraulischen Antriebsmotors wird dessen Gewicht direkt von dem Gehäuse des Planetengetriebes übernommen. Entsprechend dem Gewicht des hydraulischen Antriebsmotors sind die innerhalb des Planetengetriebes Anwendung findenden Lager und das Festlager der Pumpenwelle zu überprüfen bzw. zu gestalten.Another embodiment of the invention provides that the drive motor is connected directly to the planetary gear housing and its drive shaft or is connected to the stationary ring gear and the drive shaft of the planetary gear. With this measure, the size of the unit can be significantly reduced and e.g. when using a hydraulic drive motor, its weight is taken directly from the housing of the planetary gear. Depending on the weight of the hydraulic drive motor, the bearings used within the planetary gear and the fixed bearing of the pump shaft must be checked or designed.

Eine weitere Ausgestaltung der Erfindung sieht vor, daß ein mit dem Gehäuse des Planetengetriebes zusammenwirkender, am Pumpengehäuse oder der Laterne angebrachter Anschlag die Axialbewegung des Getriebegehäuses begrenzt. Mittels dieser Maßnahme können klar definierte Verhältnisse innerhalb des Tauchmotorpumpenaggregates eingehalten werden.A further embodiment of the invention provides that a stop cooperating with the housing of the planetary gear and attached to the pump housing or the lantern limits the axial movement of the gear housing. By means of this measure, clearly defined conditions within the submersible pump unit can be maintained.

Nach einer weiteren Ausgestaltung der Erfindung erfolgt die Lagerung der Abtriebswelle des Planetengetriebes im Bereich der Lagerebene des Planetengetriebegehäuses oder des stillstehenden Hohlrades. Hierdurch werden eventuell auftretende, in radialer Richtung wirkende Momente über das Lager und die Planetengetriebeteile aufgefangen.According to a further embodiment of the invention, the output shaft of the planetary gear is mounted in the area of the bearing plane of the planetary gear housing or the stationary ring gear. As a result, any moments that occur in the radial direction are absorbed by the bearing and the planetary gear parts.

Eine weitere Ausgestaltung der Erfindung sieht vor, daß die Drehmomentabstützung des Planetengetriebegehäuses oder des stillstehenden Hohlrades stoßdämpfend ausgebildet ist. Mittels elastischer Anschläge, wie z.B. Gummipuffer, Federpakete, Stoßdämpfer oder dgl., mit denen das Planetengetriebegehäuse drehmomentgesichert ist, werden durch das Fördermedium bedingte, von der Pumpenwelle übertragene Stöße gemildert. Das gleich gilt für die beim Anfahren des Tauchmotorpumpenaggregates auftretenden Belastungen.A further embodiment of the invention provides that the torque support of the planetary gear housing or the stationary ring gear is designed to be shock-absorbing. By means of elastic stops, e.g. Rubber buffers, spring assemblies, shock absorbers or the like, with which the planetary gear housing is secured against torque, are mitigated by the conveying medium-induced impacts transmitted by the pump shaft. The same applies to the loads that occur when the submersible pump unit starts up.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben. Es zeigen die

  • Fig. 1 ein Tauchpumpenaggregat mit Elektromotorantrieb und geschlossenen Planetengetriebe, die
  • Fig . 2 e ntsprechend der Fig. 1 die Verwendung eines offenen Planetengetriebes und die
  • Fig. 3 ein mit einem Hydraulikmotor versehenes Tauchmotorpumpenaggregat.
Embodiments of the invention are shown in the drawings and are described in more detail below. They show
  • Fig. 1 is a submersible pump unit with an electric motor drive and closed planetary gear, the
  • Fig. 2 e corresponding to Fig. 1, the use of an open planetary gear and
  • 3 shows a submersible pump unit provided with a hydraulic motor.

Die Fig. 1 zeigt ein aus einem elektrischen Antriebsmotor 1 und einem im Pumpengehäuse 2 angeordneten Axialpropeller 3 bestehendes Tauchmotorpumpenaggregat. Zwischen einer mit dem Axialpropeller 3 versehenen Pumpenwelle 4 und dem Antriebsmotor 1 ist das Planetengetriebe 5 angeordnet. Das eine kompakte bauliche Einheit bildende Planetengetriebe 5 besteht aus der Antriebswelle 6, die unter Zwischenschaltung einer flexiblen Kupplung 7 mit dem Antriebsmotor 1 verbunden ist. Das Gehäuse 8 des Planetengetriebes 5 ist in der den Antriebsmotor 1 tragenden Laterne 9 starr oder elastisch gegen Verdrehung gesichert, aber in Achsrichtung verschiebbar gelagert. Ein zwischen Gehäuse 8 und Laterne 9 angeordneter Gummiring 10 dient der Dämpfung von Vibrationen und der Abdichtung eines ggf. Anwendung findenden Ölvorlageraumes zu Kühl- und Schmierzwecken. Die Abtriebswelle 11 des Planetengetriebes 5 ist mittels einer biegemomenteübertragenden Schrumpfverbindung 12 mit der Pumpenwelle 4 verbunden.1 shows a submersible pump assembly consisting of an electric drive motor 1 and an axial propeller 3 arranged in the pump housing 2. The planetary gear 5 is arranged between a pump shaft 4 provided with the axial propeller 3 and the drive motor 1. The planetary gear 5 forming a compact structural unit consists of the drive shaft 6, which is connected to the drive motor 1 with the interposition of a flexible coupling 7. The housing 8 of the planetary gear 5 is rigidly or elastically secured against rotation in the lantern 9 carrying the drive motor 1, but is mounted displaceably in the axial direction. A rubber ring 10 arranged between the housing 8 and the lantern 9 serves to dampen vibrations and to seal an oil reservoir, which may be used, for cooling and lubrication purposes. The output shaft 11 of the planetary gear 5 is connected to the pump shaft 4 by means of a shrink connection 12 which transfers bending moments.

Die Pumpenwelle 4 ist innerhalb des Pumpengehäuses 2 in den das Festlager bildenden Radiallager 13 und Schrägkugellager 14 befestigt. Aufgrund der biegemomentübertragenden Kupplung 12 und der Lagerung innerhalb des Planetengetriebes 5 wirkt das Gehäuse 8 des Planetengetriebes als zweites Pumpenwellenlager, d .h . Loslager . Die in Fig.2 dargestellte Tauchmotorpumpe entspricht im wesentlichen der Fig. 1, nur ist hier das Planetengetriebe 5 in Richtung Axialpropeller offen ausgebildet. Die den Planetenträger bildende Abtriebswelle 11 ist hier im Bereich der Lagerebene des Planetengetriebes gelagert. Zusätzliche Momente im Getriebe werden somit vernachlässigbar kleingehalten. Eine zwischen Abtriebswelle 11 und dem Pumpengehäuse 2 angebrachte Dichtung ermöglicht es, den gesamten Raum 16 mit Öl zu füllen. Diese Maßnahme kann Anwendung finden in denjenigen Fällen, in denen vom Planetengetriebe 5 sehr große Leistungen zu übertragen sind und somit die innerhalb eines geschlossenen Planetengetriebes befindliche Ölmenge zur Kühlung und Schmierung nicht ausreichen würde. Neben der Verringerung des Teilumfanges bedeutet dies gleichzeitig einen verringerten Fertigungsaufwand .The pump shaft 4 is fastened within the pump housing 2 in the radial bearing 13 and angular contact ball bearing 14 forming the fixed bearing. Due to the bending moment transmitting clutch 12 and the bearing within the planetary gear 5, the housing 8 of the planetary gear acts as a second pump shaft bearing, i.e. Floating bearing. The submersible pump shown in FIG. 2 corresponds essentially to FIG. 1, except that the planetary gear 5 is designed to be open in the direction of the axial propeller. The output shaft 11 forming the planet carrier is mounted here in the region of the bearing plane of the planetary gear. Additional moments in the gearbox are therefore negligibly small. A seal attached between the output shaft 11 and the pump housing 2 makes it possible to fill the entire space 16 with oil. This measure can be used in those cases in which very large powers are to be transmitted from the planetary gear 5 and the amount of oil located within a closed planetary gear would therefore not be sufficient for cooling and lubrication. In addition to the reduction of the partial scope, this also means a reduced manufacturing effort.

Die Fig. 3 zeigt ein besonders kompaktes Tauchmotorpumpenaggregat, bei dem ein direkt mit dem Planetengetriebe 5 gekoppelter Antriebsmotor 17 Anwendung findet. Das Gewicht des Antriebsmotors lastet in diesem Fall auf dem Gehäuse 8 des Planetengetriebes und es ist eine Berechnungsfrage, inwieweit die hier Anwendung findenden Lager ausreichen oder anders dimensioniert werden müssen. Die Zu- bzw. Abfuhr der energiereichen Hydraulikflüssigkeit erfolgt über die Leitungen 18. Gummiblöcke 19 dienen zur Drehmomentabstützung.FIG. 3 shows a particularly compact submersible pump unit in which a drive motor 17 which is directly coupled to the planetary gear 5 is used. The weight of the drive motor in this case rests on the housing 8 of the planetary gear and it is a question of calculation to what extent the bearings used here are sufficient or have to be dimensioned differently. The supply and discharge of the high-energy hydraulic fluid takes place via the lines 18. Rubber blocks 19 serve to support the torque.
