Description

Drehkolbenpumpe Die Erfindung bezieht sich auf eine Drehkolbenpumpe, bei welcher die Kolben um Naben umlaufen, welche zentrisch im Zylinder gelagert und an dessen Deckeln angeordnet sind: Die Kolben werden von einer Kolbentrommel angetrieben, welche exzentrisch im Zylinder liegt. Die bekannten in dieser Weise ausgeführten Drehkollienpumpen besitzen den Nachteil, daß im Betrieb während der Bewegung der Räder der Kolben längs der Zylinderwände große Abnutzung verursacht wird, wodurch diese Pumpen schnell unbrauchbar werden.Rotary lobe pump The invention relates to a rotary lobe pump, in which the pistons revolve around hubs, which are mounted centrally in the cylinder and on its lids are arranged: The pistons are from a piston drum driven, which is eccentric in the cylinder. The known in this way executed rotary collien pumps have the disadvantage that in operation during the Movement of the wheels of the pistons along the cylinder walls causes great wear which quickly makes these pumps unusable.

Um diesen Nachteil zu beseitigen, werden gemäß der Erfindung diese Pumpen derart ausgebildet, daß durch Vereinigung der nachstehend angegebenen Einzelheiten die Abnutzung im Betrieb erheblich verringert wird.In order to overcome this disadvantage, according to the invention, these Pumps designed such that by combining the details given below the wear and tear in operation is significantly reduced.

i. Die antreibende Kolbentrommel ist aus zwei oder mehreren Teilen und die Kolben sind aus einem einzigen Stück gefertigt; 2. die Teile, aus welchen die Kolbentrommel besteht, sind gegenseitig und auf einer exzentrisch im Zylinder gelagerten Welle befestigt, und zwar in dem Raum zwischen den Naben, um welche die Kolben umlaufen; 3. die Kolben sind zweiseitig unterstützt. Weil die Kolbentrommel hier die Kolben antreibt und also selbst von einer exzentrisch gelagerten Welle angetrieben wird, auf welcher die Kolbentrommel befestigt ist, wird bei dem Antrieb mit gleichförmiger Bewegung dieser Welle auch der Umlauf der Kolbentrommel ein gleichförmiger sein. Da jedoch bei jeder ganzen Umdrehung ein anderer Punkt der Kolben mit der Trommel in Berührung ist, werden die Enden der Kolben, die sich die Zylinderwände entlang bewegen, keine gleichförmige Geschwindigkeit besitzen. Dadurch nun jedoch, daß der Erfindung gemäß die Kolben aus einem einzigen Stück hergestellt sind, was möglich ist, da die Trommel aus zwei oder mehreren Teilen besteht, ist es möglich, die Masse der Kolben sehr gering zu halten, so daß der Nachteil der ungleichmäßigen Geschwindigkeit entlang den Zylinderwänden auf das geringste beschränkt wird.i. The driving piston drum is made up of two or more parts and the pistons are made from a single piece; 2. the parts from which the piston barrel consists are reciprocal and on one eccentric in the cylinder mounted shaft, namely in the space between the hubs around which the Pistons rotate; 3. the pistons are supported on both sides. Because the piston drum here drives the piston and thus itself from an eccentrically mounted shaft is driven, on which the piston drum is attached, is in the drive with uniform movement of this shaft, the rotation of the piston drum becomes more uniform be. However, since a different point of the piston with the When the drum is in contact, the ends of the pistons are attached to the cylinder walls move along, do not have a uniform speed. As a result, however, that according to the invention, the pistons are made from a single piece, what is possible because the drum consists of two or more parts, it is possible to keep the mass of the piston very low, so that the disadvantage of uneven Speed along the cylinder walls is limited to the slightest.

Da ferner gemäß der Erfindung die Kolben zweiseitig gelagert sind, wird vorgebeugt, daß während des Umlaufs infolge der entstehenden Fliehkraft eine einseitige Ausweichung entstehen kann, die ebenfalls die Abnutzung und dadurch das baldige Unbrauchbarwerden der Pumpe herbeiführen würde.Since, furthermore, according to the invention, the pistons are supported on two sides, it is prevented that during the rotation due to the centrifugal force unilateral deviation can arise, which also reduces wear and tear and thus the would soon render the pump unusable.

Um diese Ausführung der Kolbenlagerung zu ermöglichen, sind erfindungsgemäß die Teile, aus welchen die Trommel besteht, miteinander und auf der Treibwelle befestigt, und zwar in dem Raum zwischen den Naben.In order to enable this design of the piston bearing are according to the invention the parts that make up the drum are attached to each other and to the drive shaft, namely in the space between the hubs.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, wobei Abb. i einen OOuerschnitt und Abb. 2 einen Längsschnitt der Pumpe veranschaulichen.The drawing shows an exemplary embodiment of the subject matter of the invention shown, with Fig. 1 a cross section and Fig. 2 a longitudinal section of the pump illustrate.

In dem Pumpenzylinder i befindet sich eine Welle 2, auf welcher die aus zwei Teilen hergestellte Kolbentrommel 3 befestigt ist. Die gegenseitige Befestigung der Trommelteile auf der Welle 2 erfolgt mittels der Schraubenbolzen 4 und erfolgt in dem Raum zwischen den in die Trommel hineinreichenden Naben 5 und 6, welche an den Zylinderdeckeln 7 und 8 angeordnet sind. Um die Nabe 5 herum sind die Ringe 9 und i i und ebenfalls um die Nabe 6 herum die Ringe io und I2 drehbar angeordnet.In the pump cylinder i there is a shaft 2 on which the Piston drum 3 made of two parts is attached. The mutual attachment the drum parts on the shaft 2 takes place by means of the screw bolts 4 and takes place in the space between the hubs 5 and 6 reaching into the drum, which at the cylinder covers 7 and 8 are arranged. The rings are around the hub 5 9 and i i and also around the hub 6 the rings io and I2 are rotatably arranged.

Mit den Ringen 9 und io bildet der Kolben 13 ein einziges Stück. Er wird also von diesen Ringen zweiseitig getragen. In derselben Weise bildet mit den Ringen i i und 12 der Kolben 14 ein einziges Stück.The piston 13 forms a single piece with the rings 9 and io. He is therefore carried on both sides of these rings. In the same way it forms with the Rings i i and 12 of the piston 14 a single piece.

Die Kolben können auch statt an den Ringen 9, 1o und i i, 12 an den Ringen i2, 9 und io, ii befestigt werden, in welchem Fall sie ebenfalls zweiseitig gelagert sind.The pistons can also be attached to the rings 9, 1o and i i, 12 instead of Rings i2, 9 and io, ii are attached, in which case they are also bilateral are stored.
