Abstract
The drive is for producing a rotary motion by means of a fluid or gaseous pressure medium in which a working shaft and an eccentric part within a housing are acted upon by at least one freely deformable expansion cell mounted between the housing and the eccentric part, such that expansion of the collapsible cell exerts a rotational moment on the eccentric part, a force that is directed along the central axis and therefore along the working shaft. The expansion cells are connected with the working medium by suitable control means. The arrangement does not allow sudden peak stresses within the chambers.
Description
Im Patentanspruch des Hauptpatents ist eine Antriebsvorrichtung zur Erzeugung einer Schwenk- oder Drehbewegung durch flüssiges oder gasförmiges Druckmedium umschrieben, wobei diese ein Gehäuse mit darin gelagerter Arbeitswelle und einen mit dieser wirkverbundenen Exzenterteil aufweist sowie mindestens eine durch Einführung des Druckmediums volumenveränderbare Expansionszelle, welche zwischen der Gehäuse-Innenwand und dem Exzenterteil angeordnet ist, auf diesen einwirkt und über Steuermittel Druckmedium aufnimmt oder abgibt, wobei die Expansionszelle eine deformierbare Walkzelle ist, bei der während ihrer Volumenänderung ein Walken der Zellenwand erfolgt, wobei durch die Volumenänderung der Walkzelle auf den Exzenterteil eine auf dessen Mittelachse gerichtete Kraft und daher auf die Arbeitswelle ein Drehmoment ausgeübt wird.
Die vorliegende Erfindung stellt eine Weiterbildung der Erfindung des Hauptpatentes dar. Diese Antriebsvorrichtung gemäss dem Patentanspruch des Hauptpatentes, bei welcher der Exzenterteil von einer zylindrischen Hülse umgeben ist, zeichnet sich dadurch aus, dass zwischen der als Drehteil ausgebildeten Hülse und dem Gehäuse Kupplungsmittel angeordnet sind, um eine Drehwinkeländerung zwischen Drehteil und Gehäuse zu verhüten.
Die Erfindung wird anschliessend beispielsweise anhand zweier Figuren erläutert. Es zeigen:
Fig. 1 eine schematische, perspektivische Darstellung eines im Gehäuse gegen Verdrehung geführten Walzenrotors,
Fig. 2 eine analoge Darstellung wie Fig. 1, in welcher die Führung mittels einer Kupplung erfolgt, in Explosionsdarstellung.
Fig. 1 zeigt in schematischer Darstellung den Exzenterteil des Walkrotors bzw. Walzenrotors, welcher Teil als zylindrische Hülse 90 mit einem festmontierten Führungsarm 92 und daran befestigten Rolle 94 ausgebildet ist, geführt in einer Kulisse 96 eines Gehäuses 98, welches dem Mantelrohr der Ausführung gemäss den Fig. 1 und 2 des Hauptpatentes entspricht.
Fig. 2 zeigt ebenfalls schematisch den Exzenterteil eines Walkrotors als zylindrische Hülse 102. Am Ende der Hülse 102 sind einander gegenüberliegende Zapfen 104, 106 mit Rollen 108, 110 befestigt. Ähnliche Rollen 112, 114 sind an dem dem Hülsenende gegenüberliegenden Gehäuse innenseitig in einer um 90O verdrehten Position angebracht. Die Koppelung der Hülse 102 mit dem Gehäuse erfolgt mittels eines Kupplungsringes 116 mit den zu den Rollen 108, 110. 112 und 114 passenden Kulissenöffnungen 118, 120, 122 und 124. Der Kupplungsring lässt auf bekannte Weise eine Achsversetzung zwischen rotierender Hülse und Gehäuse zu, wobei er jedoch jegliche relative Verdrehung verhindert (Oldham-Kupplung).
Die Ausnehmungen 118, 120, 122 und 124 dienen, wie erwähnt, der Aufnahme der Rollen 108, 110 und 112, 114.
Auf diese Weise kann die Hülse 102 im Gehäuse eine Bewegung ähnlich derjenigen eines Schubstangenkopfes an einem Kurbeltrieb ausführen, d. h. eine kreisende Bewegung um eine exzentrische Achse ausführen, ohne eine Drehbewegung um seine eigene Achse zu vollziehen.
PATENTANSPRUCH
Antriebsvorrichtung nach dem Patentanspruch des Hauptpatentes, wobei der Exzenterteil von einer zylindrischen Hülse umgeben ist, dadurch gekennzeichnet, dass zwischen der als Drehteil (90) ausgebildeten Hülse und dem Gehäuse (98) Kupplungsmittel (92, 94, 96) angeordnet sind, um eine Drehwinkeländerung zwischen Drehteil (90) und Gehäuse (98) zu verhüten.
UNTERANSPRUCH
Antriebsvorrichtung nach Patentanspruch, dadurch gekennzeichnet, dass die Kupplungsmittel als in einer Führung (96) des Gehäuses (98) gelagerter, sich radial erstreckender Arm (92) des Drehteils (90) oder als Kardankupplung, biegsame Welle oder Oldham-Kupplung (104, 108, 118, 116) ausgebil detsind.
**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
In the claim of the main patent, a drive device for generating a pivoting or rotary movement by liquid or gaseous pressure medium is described, this having a housing with a working shaft mounted therein and an eccentric part that is operatively connected to it, as well as at least one expansion cell which can be changed in volume by introducing the pressure medium and which is located between the housing -Inner wall and the eccentric part is arranged, acts on this and absorbs or releases pressure medium via control means, the expansion cell being a deformable flexing cell, in which the cell wall is flexed during its volume change, with the volume change of the flexing cell on the eccentric part Central axis directed force and therefore a torque is exerted on the output shaft.
The present invention represents a further development of the invention of the main patent. This drive device according to the claim of the main patent, in which the eccentric part is surrounded by a cylindrical sleeve, is characterized in that coupling means are arranged between the sleeve, which is designed as a rotating part, and the housing, to prevent a change in the angle of rotation between the rotating part and the housing.
The invention is then explained using two figures, for example. Show it:
1 shows a schematic, perspective illustration of a roller rotor guided in the housing against rotation,
FIG. 2 shows an illustration analogous to FIG. 1, in which the guidance takes place by means of a coupling, in an exploded view.
Fig. 1 shows a schematic representation of the eccentric part of the fulling rotor or roller rotor, which part is designed as a cylindrical sleeve 90 with a fixed guide arm 92 and attached roller 94, guided in a link 96 of a housing 98, which is the jacket tube of the embodiment according to Fig. 1 and 2 of the main patent corresponds.
2 likewise shows schematically the eccentric part of a fulling rotor as a cylindrical sleeve 102. At the end of the sleeve 102, opposing pins 104, 106 are fastened with rollers 108, 110. Similar rollers 112, 114 are attached to the inside of the housing opposite the sleeve end in a position rotated 90 °. The sleeve 102 is coupled to the housing by means of a coupling ring 116 with the link openings 118, 120, 122 and 124 that match the rollers 108, 110, 112 and 114. The coupling ring allows an axial offset between the rotating sleeve and the housing in a known manner, however, it prevents any relative rotation (Oldham coupling).
The recesses 118, 120, 122 and 124 serve, as mentioned, to accommodate the rollers 108, 110 and 112, 114.
In this way, the sleeve 102 in the housing can perform a movement similar to that of a push rod head on a crank mechanism, i. H. perform a circular motion around an eccentric axis without turning around its own axis.
PATENT CLAIM
Drive device according to claim of the main patent, wherein the eccentric part is surrounded by a cylindrical sleeve, characterized in that coupling means (92, 94, 96) are arranged between the rotating part (90) and the housing (98) to allow a change in the angle of rotation between rotating part (90) and housing (98) to prevent.
SUBClaim
Drive device according to claim, characterized in that the coupling means as a radially extending arm (92) of the rotating part (90) mounted in a guide (96) of the housing (98) or as a cardan coupling, flexible shaft or Oldham coupling (104, 108 , 118, 116) are trained.
