Im besonderen betrifft die Erfindung die Vorrichtung bzw. die Mittel zum Verstellen der Exzentrizität des Ringkörpers.Fluid change and reversing gear with one adjustable on one Eccentric arranged ring body to change the volume of the displacement cells The invention relates to fluid changing and turning, drives with a its shaft with the help of an eccentric adjustable ring body, which the volume of the displacement cells for the operating fluid changed. In particular concerns the invention the device or the means for adjusting the eccentricity of the Ring body.
Der Zweck der Erfindung ist, eine Exzenterstellvorrichtung zu schaffen, die im Aufbau möglichst einfach und billig ist, nur wenig Raum für sich in Anspruch nimmt, auch den sonstigen Aufbau des Getriebes übersichtlich läßt und vor allem eine leichte, bequeme, nahezu reibungslose Verstellung des Exzenters auch während des Betriebs ermöglicht.The purpose of the invention is to create an eccentric adjusting device, which is as simple and cheap as possible in construction, takes up little space for itself takes, also leaves the rest of the structure of the transmission clear and above all easy, comfortable, almost smooth adjustment of the eccentric even during of operation.
Hiernach besteht das Neue der Exzenterstellvorrichtung gemäß der Erfindung zunächst darin, daß das Exzenter auf einer auf der Welle sitzenden Geradführung, gegebenenfalls unter Zwischenschaltung von Rollen o. dgl., verschiebbar, und zwar zur Welle quer verschiebbar, angeordnet ist; ferner darin, daß eigens für die quer zur Welle erfolgende Verschiebung des Exzenters mit letzterem ein Stift vereinigt und dieser Stift in der .auf der Welle festsitzenden Geradführung des Exzenters verschiebbar gelagert ist, und schließlich noch darin, daß der Stift durch einen Winkelhebel mit einer in einer axialen Bohrung der Welle verschiebbaren Stange gekuppelt ist.This is the novelty of the eccentric adjusting device according to the invention first in the fact that the eccentric is on a straight guide seated on the shaft, optionally with the interposition of roles o. The like., Slidable, namely is arranged to be displaceable transversely to the shaft; also in the fact that especially for the cross to the shaft taking place displacement of the eccentric with the latter a pin combined and this pin in the straight guide of the eccentric, which is fixed on the shaft is slidably mounted, and finally that the pin by a Angle lever coupled to a rod displaceable in an axial bore in the shaft is.
Durch diese Anordnung wird gegenüber bekannten älteren Ausführungen zunächst der große Vorteil erreicht, daß die durch den Flüssigkeitsdruck hervorgerufenen Kräfte innerhalb des Gehäuses ausgeglichen werden, und daß in höchst einfacher Weise auch frei tragende Längen und hohe Biegungsmomente außerhalb des Gehäuses vermieden werden. Ein weiterer Vorteil liegt darin, daß ein Getriebe gemäß vorliegender Erfindung, verglichen mit einem Getriebe anderer Bauart, bei an sich gleicher Leistung leichter gebaut ist und auch weniger Raum für sich in Anspruch nimmt.This arrangement is compared to known older designs first of all the great advantage achieved that caused by the fluid pressure Forces within the housing are balanced, and that in a very simple way Unsupported lengths and high bending moments outside the housing are also avoided will. Another advantage is that a transmission according to the present invention, compared to a gearbox of a different design, but with the same performance, it is lighter is built and also takes up less space.
Im folgenden soll der Erfindungsgegenstand an einem Ausführungsbeispiel beschrieben werden.In the following, the subject matter of the invention is based on an exemplary embodiment to be discribed.
Auf der Zeichnung stellen dar: Abb. t ein Flüssigkeitswechsel- und -wendegetriebe im Schnitt nach Linie i-i der Abb. z, Abb. 2 dasselbe Getriebe im Schnitt nach Linie 2-2 der Abb. i, Abb.3 ein zweites Ausführungsbeispiel, teils im Schnitt und teils in Ansicht, Abb.4 den Exzenterstellhebel mit Bezug auf Abb. 2 von rechts gesehen.The drawing shows: Fig. T a fluid change and -reversing gear in section along line i-i of Fig. z, Fig. 2 the same Transmission in section along line 2-2 of Fig. I, Fig. 3 a second embodiment, partly in section and partly in view, Fig. 4 shows the eccentric adjusting lever with reference to Fig. 2 seen from the right.
Das Getriebe hat einen Ringkörper 7, welcher durch hin und her gehende Bewegung die Verdrängungszellen vergrößert bzw. verkleinert.The transmission has an annular body 7, which by going back and forth Movement increases or decreases the displacement cells.
Derartige Flüssigkeitsgetriebe sind bekannt, und da sie nicht unmittelbar zur Erfindung gehören, kann von einer näheren Beschreibung der Wirkungsweise des Getriebes abgesehen werden.Such fluid transmission are known, and since they are not immediate belong to the invention, can from a more detailed description of the operation of the Gearbox are disregarded.
Um die Buchse g von außen rechtwinklig zur Welle 12 verschieben und hiermit die Exzentrizität des Ringkörpers 7 während des Betriebes verändern zu können, ist eine besondere Einrichtung geschaffen. Ein Stift 1 ¢ ist in der Geradführung i i verschiebbar gelagert und stößt mit seinen Enden gegen die Schmalseiten der in der Buchse g befindlichen Öffnung io. Ein Verschieben des Stiftes z¢ bedingt eine Veränderung der Exzentrizität des Ringes. Die Verschiebung geschieht mit Hilfe eines Winkelhebels 18, der in einem Schlitz 18v der auf Welle i- sitzenden Geradführung i i auf einem Stift i 8a drehbar gelagert ist. Das abgerundete Ende i 8c des Winkelhebels 18 greift in einen Schlitz i9 des Stiftes 14. Das andere Ende des Winkelhebels 18 ist in das geschlitzte Ende 17a einer Stange 17 eingepaßt und mit der Stange durch einen Stift i7v verbunden. Mit einer Ringnut 17c, die sich an dem äußeren verdickten Ende der Stange 17 befindet, ist das gegabelte Ende i 5a eines Stellhebels 15 (Abb. 4) durch Stifte 15v (Abb. 2) in Eingriff gebracht. Der Hebel 15 ist sch-vingbar um einen Stift 16 und in einem besonderen Halteblock 16a gelagert. Eine Verstellung des Hebels 16 bewirkt eine Verstellung der Exzentrizität des Ringkörpers.In order to move the bushing g from the outside at right angles to the shaft 12 and thereby to be able to change the eccentricity of the annular body 7 during operation, a special device is created. A pin 1 [is slidably mounted in the straight guide ii and abuts with its ends against the narrow sides of the opening io located in the socket g. Moving the pin z ¢ causes a change in the eccentricity of the ring. The displacement takes place with the aid of an angle lever 18 which is rotatably mounted on a pin i 8a in a slot 18v of the straight guide ii seated on the shaft i. The rounded end i 8c of the angle lever 18 engages in a slot i9 of the pin 14. The other end of the angle lever 18 is fitted into the slotted end 17a of a rod 17 and connected to the rod by a pin i7v. With an annular groove 17c, which is located at the outer thickened end of the rod 17, the forked end i 5a of an adjusting lever 15 (Fig. 4) is brought into engagement by pins 15v (Fig. 2). The lever 1 5 can be swung around a pin 16 and is mounted in a special holding block 16a. An adjustment of the lever 16 effects an adjustment of the eccentricity of the ring body.
Die oben beschriebene Exzenterstellvorrichtung hat gegenüber bekannten älteren Ausführungen den bedeutenden Vorteil, daß die durch den Flüssigkeitsdruck hervorgerufenen Kräfte, wie es im folgenden noch näher beschrieben werden soll, innerhalb des Gehäuses ausgeglichen werden. Es sei beispielsweise angenommen, daß die Kammern 33a in der rechten Hälfte der Abb. i unter Druck stehen und die Kammern 33v der linken Hälfte keinen oder nur geringen Druck aufweisen. Der Flüssigkeitsdruck wird durch den Ringkörper 7, durch das Rollenlager 8, 8a, 8v, durch die Buchse 9 und durch die Rolle 13 in diesem Fall auf die rechte Seite der Geradführung i i der Welle 12 übertragen und schließlich durch die Kugellager 21 unmittelbar auf das Gehäuse abgesetzt. Verglichen mit bekannten älteren Ausführungen bietet der Gegenstand der Erfindung hier einen sehr wesentlichen Vorteil, indem in höchst einfacher Weise frei tragende Längen und hohe Biegungsmomente außerhalb des Gehäuses vermieden werden. Dies wiederum bedingt den Vorteil, daß das neue Getriebe, verglichen mit älteren Ausführungen, bei sonst gleicher Leistung einen leichteren Aufbau erhalten kann und weniger Raum für sich in Anspruch nimmt. Außerdem -wird durch die Rolle 13 zwischen der Geradführung i i und den Führungsflächen i oa der Öffnung io innerhalb der Buchse 9 eine leichte Veränderlichkeit der Exzentrizität auch unter stärkster Belastung gesichert, was namentlich für Flüssigkeitsgetriebe dieser Art von wesentlicher Bedeutung ist. Im Gegensatz hierzu ist bei Getrieben bekannter Bauart eine ungewöhnlich hohe Reibung zu über--vinden, d. h. bei ihnen -wird die Verstellung der Exzentrizität -während des Betriebes durch starke Reibung sehr erschwert. Im übrigen ist es nicht ohne weiteres möglich, die Exzenterstellvorrichtung bekannter älterer Ausführungen so umzubauen, daß sie leichter verstellbar werden.The eccentric adjusting device described above has compared to known older designs have the significant advantage that the liquid pressure evoked forces, as will be described in more detail below, be balanced within the housing. For example, assume that the chambers 33a in the right half of Fig. i are under pressure and the chambers 33v of the left half show little or no pressure. The fluid pressure is through the ring body 7, through the roller bearing 8, 8a, 8v, through the bush 9 and through the roller 13 in this case to the right side of the straight guide i i the shaft 12 and finally transmitted through the ball bearings 21 directly the housing removed. Compared to known older versions, the The subject of the invention here has a very significant advantage by being extremely simple This way, unsupported lengths and high bending moments outside the housing are avoided will. This in turn gives the advantage that the new transmission, compared with older versions, with otherwise the same performance, received a lighter structure and takes up less space. Also -will through the role 13 between the straight guide i i and the guide surfaces i oa of the opening io within the socket 9 a slight variability of the eccentricity even under the strongest Load secured, which is particularly essential for fluid transmissions of this type Meaning is. In contrast, one is unusual in transmissions of known design to overcome high friction, d. H. with them -will adjust the eccentricity - very difficult during operation due to strong friction. Besides, it is not easily possible, the eccentric adjusting device of known older designs to be rebuilt so that they are easier to adjust.
Ein weiterer Vorteil der Erfindung liegt gegenüber älteren Ausführungen darin, daß die Exzenterstellvorrichtung sich sowohl für Ausführungen mit feststehendem Gehäuse und drehbarer Welle als auch für Ausführungen mit feststehender Welle und drehbarem Gehäuse überaus einfach und verhältnismäßig billig durchführen läßt. Die Verstellung wird, -wie schon oben beschrieben, in sehr einfacher Weise durch einen zur Welle quer verschiebbaren Stift 14 vermittelt, indem derselbe mit einem Winkelhebel 18 und dieser wiederum mit einer in der Welle axial verschiebbaren Stange 17 bewegt wird.Another advantage of the invention is over older versions in that the eccentric adjusting device is suitable for both versions with a fixed Housing and rotating shaft as well as for versions with fixed shaft and rotatable housing can be carried out extremely easily and relatively cheap. the Adjustment is, as already described above, in a very simple manner by a to the shaft transversely displaceable pin 14 mediated by the same with an angle lever 18 and this in turn moves with a rod 17 axially displaceable in the shaft will.
In Abb. 3 ist ein Beispiel für Getriebe mit feststehender Welle und umlaufendem Gehäuse gezeigt. (In der Ausführung nach Abb.2 ist das Gehäuse feststehend und die Welle 12 drehbar.)In Fig. 3 is an example of a gearbox with a fixed shaft and surrounding housing shown. (In the version according to Fig. 2 the housing is fixed and the shaft 12 rotatable.)
