Abstract

The motor has a housing (1), a shaft (7) and two blades (3, 9) that are respectively arranged on the housing side and on the shaft side. Two working chambers (13, 15) are formed between the housing and the blade on the housing side and between the shaft and the blade on the shaft side. The working chambers are axially sealed by a pressure plate (19). The pressure plate is fixed either on the housing side or on the rotor side, and flexibly bears against respective other part. Blade seals are made of polytetrafluoroethylene (PTFE).

Description

Die Erfindung betrifft einen Schwenkflügelmotor mit einem Gehäuse und mindestens einem gehäuseseitig angeordneten Flügel (als Stator) und einer Welle mit mindestens einem wellenseitig angeordneten Flügel (als Rotor), wobei zwischen dem Gehäuse und dem gehäuseseitigen Flügel und der Welle und dem wellenseitigen Flügel mindestens zwei Arbeitsräume gebildet werden, welche axial durch mindestens eine Druckplatte abgedichtet werden. Derartige Schwenkflügelmotoren sind bekannt.The invention relates to a swing-wing motor with a housing and at least one housing-side arranged wing (as a stator) and a shaft with at least one shaft side arranged wing (as a rotor), wherein between the housing and the housing-side wing and the shaft and the shaft side wing at least two working spaces are formed, which are sealed axially by at least one pressure plate. Such swing wing motors are known.

Dabei tritt das Problem auf, dass im drucklosen Zustand die Druckplatte noch keine Dichtwirkung erzeugen kann und damit die Dichtwirkungen bei den Anfahrbedingungen des Schwenkflügelmotors undefiniert sind.In this case, the problem arises that in the pressureless state, the pressure plate can not produce a sealing effect and thus the sealing effects in the starting conditions of the swing-wing motor are undefined.

Es ist daher Aufgabe der Erfindung, einen Schwenkflügelmotor darzustellen, welcher diese Probleme nicht aufweist.It is therefore an object of the invention to present a swing-wing motor, which does not have these problems.

Die Aufgabe wird gelöst durch einen Schwenkflügelmotor mit einem Gehäuse und mindestens einem gehäuseseitig angeordneten Flügel (als Stator) und einer Welle und mindestens einem wellenseitig angeordneten Flügel (als Rotor), wobei zwischen dem Gehäuse und dem gehäuseseitigen Flügel und zwischen der Welle und dem wellenseitigen Flügel mindestens zwei Arbeitsräume gebildet werden, welche axial durch mindestens eine Druckplatte abgedichtet werden, wobei die Druckplatte entweder gehäuseseitig oder rotorseitig eingespannt ist und am jeweils anderen Teil federnd anliegt. Das hat den Vorteil, dass eine Dichtwirkung der Druckplatte auch schon im drucklosen Zustand realisiert wird. Die Druckplatte ist also gleichzeitig Federelement, um eine Vorspannung herzustellen und dadurch die gewünschte Dichtwirkung auch im drucklosen Zustand (fail-safe) sicherzustellen. Weitere Vorspannelemente entfallen.The object is achieved by a swing-wing motor with a housing and at least one housing-side arranged wing (as a stator) and a shaft and at least one shaft side arranged wing (as a rotor), wherein between the housing and the housing side wing and between the shaft and the shaft side wing at least two working spaces are formed, which are sealed axially by at least one pressure plate, wherein the pressure plate is clamped either on the housing side or the rotor side and bears resiliently on the other part. This has the advantage that a sealing effect of the pressure plate is realized even in the unpressurized state. The pressure plate is thus simultaneously spring element to produce a bias and thereby ensure the desired sealing effect even in the non-pressurized state (fail-safe). Further biasing elements omitted.

Bevorzugt wird ein Schwenkflügelmotor, welcher zwei Druckplatten aufweist, welche symmetrisch zwischen dem Gehäuse und dem Rotor angeordnet sind. Das hat den Vorteil, dass eine symmetrische Anordnung zweier Druckplatten die axiale Zentrierung des Rotorflügelabschnittes gewährleistet.Preference is given to a swing-wing motor, which has two pressure plates, which are arranged symmetrically between the housing and the rotor. This has the advantage that a symmetrical arrangement of two pressure plates ensures the axial centering of the rotor blade section.

Ein erfindungsgemäßer Schwenkflügelmotor zeichnet sich dadurch aus, dass die Vorspannung durch die geometrische Form der Druckplatte, welche bei der Montage des Schwenkflügelmotors verformt wird, aufgebracht wird. Auch wird ein Schwenkflügelmotor bevorzugt, bei welchem die Druckplatte eine Entlastungsnut zur gezielten lokalen Verformung aufweist. Das hat den Vorteil, dass die Verformungsstelle an einer definierten Stelle angebracht werden kann und die übrigen Teile der Druckplatte als Dichtungsauflagefläche dienen, ohne sich zu verformen und damit ohne die Dichtfläche zu verändern.An inventive swing-wing motor is characterized in that the bias is applied by the geometric shape of the pressure plate, which is deformed during assembly of the swing-wing motor. Also, a swing-wing motor is preferred at which the pressure plate has a relief groove for targeted local deformation. This has the advantage that the deformation point can be attached to a defined location and serve the remaining parts of the pressure plate as a sealing bearing surface, without deforming and thus without changing the sealing surface.

Auch wird ein Schwenkflügelmotor bevorzugt, bei welchem mindestens eine Druckplatte Durchleitungsbohrungen für je einen Arbeitsraum aufweist. Das hat den Vorteil, dass die Leitungen axial am Schwenkmotor angebracht werden können und nicht den radialen Bauraum vergrößern.Also, a swing-wing motor is preferred in which at least one pressure plate has through holes for each working space. This has the advantage that the lines can be mounted axially on the swivel motor and do not increase the radial space.

Weiterhin wird ein Schwenkflügelmotor bevorzugt, bei welchem der Arbeitsdruck in dem jeweils mit Betriebsdruck beaufschlagten Arbeitsraum durch einen Umschaltmechanismus in den Druckraum hinter der Druckplatte (zwischen axialer Gehäusewand und Druckplatte) geleitet wird, gegebenenfalls durch einen Ventil- Umschaltmechanismus.Furthermore, a swing-wing motor is preferred in which the working pressure in the working space acted upon by operating pressure is passed through a switching mechanism in the pressure chamber behind the pressure plate (between the axial housing wall and pressure plate), optionally by a valve switching mechanism.

Ein weiterer erfindungsgemäßer Schwenkflügelmotor zeichnet sich dadurch aus, dass der Umschaltmechanismus in die Flügeldichtungsvorrichtung integriert wird. Auch wird ein Schwenkflügelmotor bevorzugt, bei welchem der Umschaltmechanismus durch Bohrungen unterhalb der Flügeldichtung im Rotorflügel realisiert ist, wenn die Druckplatte gehäuseseitig eingespannt ist, oder im Gehäuseflügel, wenn die Druckplatte rotorseitig eingespannt ist. Weiterhin wird ein Schwenkflügelmotor bevorzugt, bei welchem die mit dem Arbeitsdruck beaufschlagte Seite der Flügeldichtung die Flügeldichtung zusammenpresst oder verschiebt und daher die jeweilige Bohrung im Flügel zur Druckkammer hinter der Druckplatte freigibt. Das hat den Vorteil, dass keine separaten Ventileinrichtungen benötigt werden, sondern dass die zusammenpressbare oder verschiebbare Flügeldichtung gemeinsam mit den Bohrungen diese Ventilfunktion wahrnimmt.Another inventive swing-wing motor is characterized in that the switching mechanism is integrated into the wing sealing device. Also, a swing-wing motor is preferred in which the switching mechanism is realized by bores below the wing seal in the rotor blade when the pressure plate is clamped on the housing side, or in the housing wing when the pressure plate is clamped on the rotor side. Furthermore, a swing-wing motor is preferred in which the acted upon with the working pressure side of the wing seal compresses or displaces the wing seal and therefore releases the respective hole in the wing to the pressure chamber behind the pressure plate. This has the advantage that no separate valve devices are needed, but that the compressible or displaceable leaf seal together with the holes performs this valve function.

Auch wird ein Schwenkflügelmotor bevorzugt, bei welchem die Flügeldichtungen aus PTFE bestehen. Weiterhin wird ein Schwenkflügelmotor bevorzugt, bei welchem die Druckplatte zusätzliche Dichtungen zur Abgrenzung bestimmter Druckfelder aufweist.Also, a swing-wing motor is preferred in which the wing seals are made of PTFE. Furthermore, a swing-wing motor is preferred in which the pressure plate has additional seals for the delimitation of certain pressure fields.

In Figur 1 ist ein erfindungsgemäßer Schwenkflügelmotor in einer dreidimensionalen Explosionsdarstellung gezeigt. In einem Gehäuse 1 sind zwei gehäuseseitig angeordnete Flügel 3 dargestellt, welche jeweils eine Nut 5 für eine entsprechende Dichtungseinrichtung aufweisen. Das Gehäuse 1 mit den gehäuseseitigen Flügeln 3 kann auch als Stator bezeichnet werden. Innerhalb des Gehäuses 1 ist drehbar eine Welle 7 mit zwei wellenseitig angeordneten Flügeln 9 eingebracht, wobei die Welle 7 und die beiden Flügel 9 auch als Rotor bezeichnet werden können. Auch die wellenseitig angeordneten Flügel 9 enthalten je eine Dichtungsnut 11. Zwischen den Flügeln 3 des Gehäuses 1 und den Flügeln 9 der Welle bilden sich Arbeitsräume 13 bzw. 15, welche je nach Position zwischen den Flügeln 9 und den Flügeln 3 größer oder kleiner sein können. Die Welle 7 mit ihren beiden Flügeln 9 kann also im Gehäuse 1 zwischen den beiden gehäuseseitigen Flügeln 3 in den Arbeitsräumen hin und her oszillieren und somit eine winkelmäßig begrenzte Drehbewegung in die eine oder andere Richtung machen, also eine so genannte Schwenkbewegung. Derartige Schwenkmotoren werden beispielsweise dafür eingesetzt, in einem Wankstabilisierungssystem eines Kraftfahrzeuges den Querstabilisator entsprechend zu verdrehen, wobei die eine Stabilisatorhälfte am Gehäuse 1 und die andere Stabilisatorhälfte an der Welle 7 befestigt ist. Das Gehäuse 1 kann durch einen entsprechenden Gehäusedeckel 17 verschlossen werden. Zur axialen Abdichtung des Gehäuses 1 mit den beiden gehäuseseitigen Flügeln 3 und der Welle 7 mit den beiden wellenseitigen Flügeln 9 wird eine Druckplatte 19 eingebracht. Sowohl im Gehäusedeckel 17 als auch in der Druckplatte 19 sind Durchgangsöffnungen 21 a bzw. 21 b zur Befüllung und Entleerung der Arbeitsräume 13 als auch Durchgangsöffnungen 23 a bzw. 23 b zur Befüllung und Entleerung der Arbeitsräume 15 eingebracht. Die jeweils gegenüber liegende Arbeitsräume werden durch hier nicht dargestellte Querverbindungen in der Welle mit Druck beaufschlagt. In Figur 2 ist die Druckplatte 19 vergrößert dargestellt. Neben den Durchgangsöffnungen 21 b und 23 b ist eine so genannte Entlastungsnut 25 dargestellt, welche in diesem Bereich eine gezielte elastische Verformung ermöglicht, wie später noch in Figur 5 erläutert wird.In FIG. 1 an inventive swing-wing motor is shown in a three-dimensional exploded view. In a housing 1, two housing-side arranged wings 3 are shown, which each have a groove 5 for a corresponding sealing device. The housing 1 with the housing-side wings 3 can also be referred to as a stator. Within the housing 1, a shaft 7 is rotatably mounted with two wings arranged on the shaft side 9, wherein the shaft 7 and the two wings 9 can also be referred to as a rotor. Also the shaft side arranged wings 9 each contain a sealing groove 11. Between the wings 3 of the housing 1 and the wings 9 of the shaft form working spaces 13 and 15, which may be larger or smaller depending on the position between the wings 9 and the wings 3 , The shaft 7 with its two wings 9 can thus oscillate back and forth in the housing 1 between the two housing-side wings 3 in the work spaces and thus make an angular limited rotational movement in one or the other direction, ie a so-called pivoting movement. Such swivel motors are used, for example, to turn the anti-roll bar in accordance with a roll stabilization system of a motor vehicle, with one stabilizer half being fastened to the housing 1 and the other stabilizer half to the shaft 7. The housing 1 can be closed by a corresponding housing cover 17. For axial sealing of the housing 1 with the two housing-side wings 3 and the shaft 7 with the two shaft-side wings 9, a pressure plate 19 is introduced. Both in the housing cover 17 and in the pressure plate 19 are through holes 21 a and 21 b for filling and emptying of the working spaces 13 and through holes 23 a and 23 b for filling and emptying of the working spaces 15 introduced. The respective opposing work spaces are pressurized by cross connections in the shaft, not shown here. In FIG. 2 the pressure plate 19 is shown enlarged. In addition to the passage openings 21 b and 23 b, a so-called relief groove 25 is shown, which allows a targeted elastic deformation in this area, as later in FIG. 5 is explained.

In Figur 3 ist ein derartiger Schwenkflügelmotor im Querschnitt dargestellt. Gleiche Teile wie in Figur 1 sind mit gleichen Bezugszeichen versehen. Das Gehäuse 1 wird durch den Deckel 17 verschlossen, wobei zwischen dem Gehäuse 1 und dem Deckel 17 die Druckplatte 19 eingespannt ist. Innerhalb des Gehäuses 1 ist die Welle 7 entsprechend angeordnet und in dem Deckel 17 als auch in einem zweiten Deckel 27 gelagert. Zwischen dem Deckel 27 und dem Gehäuse 1 ist eine zweite Druckplatte 29 eingespannt. Der hier dargestellte Querschnitt geht im Rotorbereich, also im Bereich der Welle 7, durch die wellenseitigen Flügel (Flügel 9 in Figur 1) und innerhalb dieser Flügel durch die Flügeldichtung 33. Der Arbeitsraum 31 ist über die Durchgangsöffnung 21 a im Deckel 17 und die Durchgangsöffnung 21 b in der Druckplatte 19 mit der Druckversorgung (hier nicht dargestellt) des Schwenkflügelmotors verbunden. Man erkennt im Querschnitt, dass beispielsweise zwischen dem Gehäusedeckel 17 und der Druckplatte 19 ein Druckraum 35 dargestellt ist sowie zwischen dem zweiten Gehäusedeckel 27 und der zweiten Druckplatte 29 ein zweiter Druckraum 37. Diese Druckräume 35 bzw. 37 werden aus den jeweils mit Druck beaufschlagten Arbeitsräumen (in Figur 1 die Arbeitsräume 13 oder 15) mit Druck beaufschlagt, wie in Figur 6 und 7 noch beschrieben wird. Die jeweils gegenüberliegenden Druckräume 13 aus Figur 1 bzw. 15 aus Figur 1 sind jeweils durch Durchgangsbohrungen 38 bzw. 39 in der Welle miteinander verbunden.In FIG. 3 Such a swing-wing motor is shown in cross-section. Same parts as in FIG. 1 are provided with the same reference numerals. The housing 1 is closed by the cover 17, wherein between the housing 1 and the cover 17, the pressure plate 19 is clamped. Within the housing 1, the shaft 7 is arranged accordingly and stored in the lid 17 and in a second cover 27. Between the cover 27 and the housing 1, a second pressure plate 29 is clamped. The cross-section shown here is in the rotor region, ie in the region of the shaft 7, by the shaft-side wing (wing 9 in FIG. 1 ) and within these wings by the wing seal 33. The working space 31 is connected via the passage opening 21 a in the lid 17 and the passage opening 21 b in the pressure plate 19 with the pressure supply (not shown here) of the swing-wing motor. It can be seen in cross-section that, for example, between the housing cover 17 and the pressure plate 19, a pressure chamber 35 is shown and between the second housing cover 27 and the second pressure plate 29, a second pressure chamber 37. These pressure chambers 35 and 37 are from each acted upon with pressure working spaces (in FIG. 1 the work spaces 13 or 15) is pressurized, as in FIGS. 6 and 7 will be described. The respective opposite pressure chambers 13 from FIG. 1 or 15 off FIG. 1 are each interconnected by through holes 38 and 39 in the shaft.

In Figur 4 ist ein Querschnitt A-A durch Figur 3 dargestellt. Innerhalb des Gehäuses 1 ist grau schraffiert dargestellt die Druckplatte 19 angeordnet. Vor der Druckplatte 19 sind die gehäuseseitigen und rotorseitigen Ausführungen mit den Flügeln dargestellt. Das Gehäuse 1 weist die beiden gehäuseseitigen Flügel 3 auf, die Welle 7 weist die beiden wellenseitigen Flügel 9 auf. Zwischen diesen Flügeln 3 bzw. 9 sind die Arbeitsräume 15 bzw. 13 ausgebildet, welche je nach Ansteuerung mit Hochdruck beaufschlagt werden oder zum Tank hin abgeleitet werden. Innerhalb der Flügel sind Flügelnuten 43 mit Dichtungen 41 angeordnet.In FIG. 4 is a cross section AA through FIG. 3 shown. Within the housing 1 gray hatched shown the pressure plate 19 is arranged. Before the pressure plate 19, the housing-side and rotor-side versions are shown with the wings. The housing 1 has the two housing-side wings 3, the shaft 7 has the two shaft-side wings 9. Between these wings 3 and 9, the working chambers 15 and 13 are formed, which are subjected to high pressure depending on the control or discharged to the tank. Within the wing wing grooves 43 are arranged with seals 41.

In Figur 5 ist die erfindungsgemäße Druckplatte 19 in ihrer konkreten Ausführung im Querschnitt zusammen mit dem Gehäuse 1, mit dem Deckel 17 und mit der Welle 7 dargestellt. In Figur 5 a ist die Welle 7 noch nicht im montierten Zustand im Gehäuse 1 angebracht. Die Druckplatte 19 wird mit einem Abschnitt 45 in eine Nut zwischen dem Deckel 17 und dem Gehäuse 1 eingeklemmt. Unterhalb der Entlastungsnut 25 besitzt die Druckplatte 19 eine konisch nach vorne auslaufende Oberfläche 47.In FIG. 5 the pressure plate 19 according to the invention in its specific embodiment in cross section together with the housing 1, with the cover 17 and with the shaft 7 is shown. In FIG. 5 a, the shaft 7 is not mounted in the assembled state in the housing 1. The pressure plate 19 is clamped with a portion 45 in a groove between the lid 17 and the housing 1. Below the relief groove 25, the pressure plate 19 has a conical forward expiring surface 47th

In Figur 5 b ist dann die Welle 7 im montierten Zustand innerhalb des Gehäuses gezeigt. Die Welle 7 hat sich mit ihrem Flügel 9 gegen die Oberfläche 47 der Druckplatte 19 gepresst, sodass diese Oberfläche jetzt federnd in einer senkrechten Position gegen den Flügel 9 der Welle 7 drückt. Die Verformung der Druckplatte 19 ist durch die Entlastungsnut 25 gezielt innerhalb dieser Entlastungsnut 25 realisiert, sodass der untere Teil der Druckplatte 19 seine Form beibehält und damit eine glatte, dichtende Oberfläche 47 gegenüber dem Flügel 9 der Welle 7 aufweisen kann. Durch diese federnde Kraft dieser ausgeformten Druckplatte wird schon eine Abdichtung garantiert, ohne dass ein zusätzlicher Druck im Druckraum 35 die Druckplatte 19 anpressen muss. Erst bei Einschalten des Hydrauliksystems wird der Druckraum 35 zusätzlich mit dem Arbeitsdruck aus den Arbeitsräumen 13 bzw. 15 beaufschlagt und damit die Druckplatte 19 zusätzlich hydraulisch axial gegen die Welle und den Wellenflügel 9 gepresst. In Figur 5c sind beide Druckplatten 19 und 29, wie beispielsweise in Figur 3 dargestellt, im Querschnitt zu sehen. Dabei ist zu erkennen, dass durch die federnden Anlagekräfte der beiden Druckplatten 19 und 29 die Welle 7 mit ihrem Flügel 9 zentriert wird. Somit ist schon im drucklosen Zustand eine zentrierte Position des Rotors, bestehend aus der Welle 7 und den Flügeln 9 gegenüber dem Stator, bestehend aus dem Gehäuse 1 und den Gehäuseflügeln 3, hergestellt.In FIG. 5 b then the shaft 7 is shown in the mounted state within the housing. The shaft 7 has pressed with its wing 9 against the surface 47 of the pressure plate 19, so that this surface now resiliently presses in a vertical position against the wing 9 of the shaft 7. The deformation of the pressure plate 19 is realized by the relief groove 25 specifically within this relief groove 25, so that the lower part of the pressure plate 19 maintains its shape and thus may have a smooth, sealing surface 47 relative to the wing 9 of the shaft 7. By this resilient force of this molded pressure plate is already a seal guaranteed without an additional pressure in the pressure chamber 35, the pressure plate 19 must press. Only when switching on the hydraulic system, the pressure chamber 35 is additionally acted upon by the working pressure from the working spaces 13 and 15 and thus the pressure plate 19 additionally hydraulically pressed axially against the shaft and the wave wing 9. In FIG. 5c Both are printing plates 19 and 29, such as in FIG. 3 shown, seen in cross section. It can be seen that the shaft 7 is centered with its wing 9 by the resilient contact forces of the two pressure plates 19 and 29. Thus, even in the pressureless state, a centered position of the rotor, consisting of the shaft 7 and the blades 9 relative to the stator, consisting of the housing 1 and the housing wings 3, made.

In Figur 6 ist eine Umschaltvorrichtung mittels der Flügeldichtung 49 dargestellt, mit welcher der Arbeitsdruck aus den jeweils mit Druck beaufschlagten Arbeitsräumen 13 oder 15 in den Druckraum 35 hinter der Druckplatte 19 eingebracht werden kann, um die Druckplatte 19 zusätzlich hydraulisch gegen den Rotor zu pressen. Die Flügeldichtung 49 ist in ihrer Breite schmaler als die Dichtungsnut 43. Zusätzlich sind in der Dichtungsnut 43 zwei Bohrungen 51 und 53 angebracht, welche im Querschnitt in Figur 7 zu erkennen sind. Die Flügeldichtung 43 wird auf der Oberfläche 55 beispielsweise durch einen Arbeitsdruck beaufschlagt und somit über die Bohrung 53 gedrückt, wodurch die Bohrung 51 frei wird. Über die Bohrung 51 kann nun der Arbeitsdruck in den Druckraum 35 hinter der Druckplatte 19 gelangen und diese damit axial gegen den Rotor drücken. In Figur 6 b wirkt der Arbeitsdruck auf die entgegen gesetzte Fläche 57. Die Flügeldichtung 49 wird innerhalb der Flügeldichtungsnut 43 über die Bohrung 51 geschoben, sodass die Schrägbohrung 53 frei wird. Somit wird jetzt der aus anderer Richtung kommende Arbeitsdruck über die Bohrung 53 in den Druckraum 35 hinter der Druckplatte 19 eingebracht und kann diese ebenfalls wieder axial gegen den Rotor drücken.In FIG. 6 a switching device by means of the wing seal 49 is shown, with which the working pressure can be introduced from the respective pressurized working spaces 13 or 15 in the pressure chamber 35 behind the pressure plate 19 to additionally press the pressure plate 19 hydraulically against the rotor. The wing seal 49 is narrower in width than the seal groove 43. In addition, two holes 51 and 53 are mounted in the seal groove 43, which in cross section in FIG. 7 can be seen. The wing seal 43 is acted upon on the surface 55, for example by a working pressure and thus pressed over the bore 53, whereby the bore 51 is free. About the bore 51 can now reach the working pressure in the pressure chamber 35 behind the pressure plate 19 and thus press it axially against the rotor. In FIG. 6 b the working pressure acts on the opposite surface 57. The wing seal 49 is pushed within the Flügeldichtungsnut 43 via the bore 51, so that the oblique bore 53 is free. Thus, now coming from another direction working pressure is introduced through the bore 53 in the pressure chamber 35 behind the pressure plate 19 and can also push them again axially against the rotor.

Die Erfindung weist also folgende Vorteile auf:

  1. a.) Die Verwendung einer Druckplatte 19 bzw. 29 zur Axialspalt-Kompensation, wobei die Druckplatte 19 bzw. 29 gleichzeitig Federelement ist, um eine Vorspannung einzuleiten und dadurch die gewünschte Dichtwirkung auch im drucklosen Zustand (fail-safe) sicher zu stellen. Weitere Vorspannelemente entfallen.
  2. b.) Klemmung der Druckplatte 19, 29 entweder am äußeren (gehäuseseitigen) oder inneren (rotorseitigen) Rand, wobei mit der äußeren Klemmung geringe Relativbewegungen erreicht werden (d. h. geringeres Reibemoment). In diesem Fall ist die gehäuseseitige Klemmung dargestellt.
  3. c.) Die Vorspannung ergibt sich aus der geometrischen Anordnung im System Schwenkmotor und wird bei der Montage durch Verformen aufgebracht.
  4. d.) Eine symmetrische Anordnung zweier Druckplatten 19, 29 gewährleistet die axiale Zentrierung des Rotorflügelabschnittes 9.
  5. e.) Die Vorspannung ist für den drucklosen Zustand so bemessen, dass ein internes axiales Spiel überbrückt werden kann, ohne dass die zur Abdichtung erforderliche Pressung auf die Stirnfläche verloren geht.
  6. f.) Die federnde Eigenschaft der Druckplatten 19, 29 ermöglicht eine Kompensation von Längendifferenzen zwischen Rotor und Stator (Gehäuse 1), z. B. infolge von Herstellungstoleranzen und Temperaturdifferenzen.
  7. g.) Falls das Arbeitsmedium seitlich in die Arbeitsräume 13, 15 des Schwenkmotors eingeleitet werden soll, können die Druckplatten 19, 29 am Rand im Bereich der ringförmigen Klemmzone mit Durchleitungsbohrungen 21 b, 23 b versehen werden, die für eine Verbindung mit Druckanschlüssen am Deckel 17 sorgen. Die Abdichtung zur deckelseitigen Druckplattenkammer wird durch die hohe Pressung zwischen den Druckplatten 19, 29 und den Deckeln 17, 27 gewährleistet.
  8. h.) Der Arbeitsdruck wird von dem beim Schwenkvorgang jeweils mit Betriebsdruck beaufschlagten Arbeitsraum 13, 15 durch einen Umschaltmechanismus in den Druckraum 35, 37 hinter der Druckplatte 19, 29 geleitet.
  9. i.) Eine mögliche Ausführung des Umschaltmechanismus besteht in dessen Integration in die Flügeldichtung 49. Kernelement ist hier eine (oder mehrere) Bohrung(en) 51, 53, die den mit Arbeitsdruck beaufschlagten Arbeitsraum 13, 15, von der Flügeldichtungsnut 43 ausgehend, mit dem Druckraum 35, 37 verbindet. Der Umschaltmechanismus nutzt die Verformung oder Verschiebung der arbeitsdruckbeaufschlagten Flügeldichtung 49, die zu einer Freilegung der Bohrungsöffnungen 51, 53 hin zu dem druckbeaufschlagten Druckraum 35, 37 führt.
  10. j.) In Kombination mit weichen Flügeldichtungen 49 (zum Beispiel aus PTFE) sorgt die beschriebene Stirndichtung für eine bessere Dichtheit an den kritischen Ecken.
The invention thus has the following advantages:
  1. a.) The use of a pressure plate 19 and 29 for axial gap compensation, wherein the pressure plate 19 and 29 simultaneously spring element to initiate a bias and thereby ensure the desired sealing effect even in the non-pressurized state (fail-safe). Further biasing elements omitted.
  2. b.) clamping of the pressure plate 19, 29 either on the outer (housing side) or inner (rotor-side) edge, with the outer clamping small relative movements are achieved (ie lower friction torque). In this case, the housing-side clamp is shown.
  3. c.) The bias results from the geometric arrangement in the system swing motor and is applied during assembly by deformation.
  4. d.) A symmetrical arrangement of two pressure plates 19, 29 ensures the axial centering of the rotor blade section 9.
  5. e.) The preload is designed for the non-pressurized state so that an internal axial clearance can be bridged without the pressure required for sealing on the end face is lost.
  6. f.) The resilient property of the pressure plates 19, 29 allows compensation of differences in length between the rotor and stator (housing 1), z. B. as a result of manufacturing tolerances and temperature differences.
  7. g.) If the working medium is to be introduced laterally into the working spaces 13, 15 of the swivel motor, the pressure plates 19, 29 at the edge in the region of the annular clamping zone with through holes 21 b, 23 b are provided, for a connection to pressure connections on the lid 17 worry. The seal to the cover-side pressure plate chamber is ensured by the high pressure between the pressure plates 19, 29 and the covers 17, 27.
  8. h.) The working pressure is passed from the acted upon during the pivoting operation with working pressure working space 13, 15 by a switching mechanism in the pressure chamber 35, 37 behind the pressure plate 19, 29.
  9. i.) A possible embodiment of the switching mechanism consists in its integration in the leaf seal 49. Core element here is one (or more) bore (s) 51, 53, which is the working pressure applied to working space 13, 15, starting from the Flügeldichtungsnut 43, with the pressure chamber 35, 37 connects. The switching mechanism utilizes the deformation or displacement of the working pressure-loaded vane seal 49, which leads to an exposure of the bore openings 51, 53 toward the pressurized pressure chamber 35, 37.
  10. j.) In combination with soft sash gaskets 49 (made of PTFE, for example), the described end seal ensures better tightness at the critical corners.

Die Erfindung umfasst also mindestens eine Druckplatte 19, 29, die gleichzeitig Federeigenschaften hat und für eine vorgespannte Abdichtung an den Stirnflächen zwischen benachbarten Schwenkflügelarbeitsräumen 13, 15 sorgt und das Axialspiel zwischen Rotor und Gehäuse 1 kompensiert.The invention thus comprises at least one pressure plate 19, 29, which has spring properties at the same time and provides for a prestressed seal at the end faces between adjacent Schwenkflügelarbeitsräumen 13, 15 and compensates for the axial play between the rotor and the housing 1.
