Description

Die vorliegende Erfindung betrifft eine Kraftzellenanordnung für Druckluft-Radialmotoren, mit einer Mehrzahl, rosettenför­mig zueinander angeordnete, in drucklosem Zustand angenähert ebene, zum wechselseitigen Aufblasen mit Luftanschlussmitteln versehene Kraftzellen, die durch Verschweissung von zwei Kunststoff-Folienblätter entlang der Zellen-Peripherien ge­bildet sind.The present invention relates to a force cell arrangement for compressed air radial motors, with a plurality of force cells arranged in a rosette-like manner, approximately flat in the depressurized state and provided with air connection means for mutual inflation, which are formed by welding two plastic foil sheets along the cell peripheries.

Durch die CH-Patentschriften 589'232 resp. 595'572 sind be­reits Kraftzellenanordnungen der vorgenannten Art bekannt ge­worden, die aus zugfesten Kunststoffolienblättern hergestellt sind, welche durch Schweissen verbunden werden, um einen Balg zu bilden. Diese bekannten Kraftzellen sind entweder mit kreisscheibenförmigem Grundriss konzipiert, oder weisen aber einen Grundriss auf, dessen Berandung abwechselnd durch kon­vexe und konkave Partien gebildet wird. Sind, wie im ersten Fall, die Kraftzellen durch zwei kreisscheibenförmige Folien­blätter, die entlang ihrer Kreisperipherie verschweisst sind, gebildet, so bieten diese wohl den Vorteil einer einfachen Werkzeugfertigung zur Herstellung der Folienblätter, erwei­sen sich jedoch bezüglich der auftretenden Folienspannungen in den verschiedenen Hublagen als problematisch. Die Ursache dazu bilden die bei der funktionsbedingten Verkürzung der Um­fanglänge auftretenden, tangentialen Druckkräfte, welche ab einer kritischen Hubhöhe Einknickungen am Zellenrand, ent­sprechend den Nahtpartien, verursachen, was die Lebensdauer der Zellen erheblich mindert. Um dem entgegen zu wirken, wur­den Kraftzellen entsprechend der zweiten erwähnten Konstruk­tionsweise entworfen, bei welchen die in den konkaven Rand­partien entstehenden Tangentialdruckkräfte durch entstehende Tangentialzugkräfte an den konvexen Umfangsstellen wenigstens partiell eliminiert werden. Aber auch dies hat zu keinen brauchbaren Ergebnissen geführt, weshalb sich auf die Wir­kung solcher Kraftzellen beruhende Druckluft-Radialmotoren trotz deren hervorragende Eigenschaften bisher nicht durch­setzen konnten. Druckluft-Radialmotoren dieser Art sind in den CH-Patentschriften 556'968 und 578'678 ausführlich be­schrieben.Through the CH patents 589'232 resp. 595,572 force cell arrangements of the aforementioned type are already known, which are made from tensile plastic sheet sheets, which are connected by welding to form a bellows. These known power cells are either designed with a circular disk-shaped outline, or have a floor plan, the edges of which are alternately formed by convex and concave parts. If, as in the first case, the force cells are formed by two circular disk-shaped foil sheets that are welded along their circular periphery, these probably offer the advantage of simple tool manufacture for the production of the foil sheets, but prove to be problematic with regard to the foil tensions that occur in the various stroke positions . The reason for this are the tangential compressive forces that occur when the circumferential length is shortened, which cause kinks at the cell edge, corresponding to the seam parts, from a critical lifting height, which considerably reduces the lifespan of the cells. In order to counteract this, force cells were designed in accordance with the second construction method mentioned, in which the tangential compressive forces arising in the concave edge parts are at least partially eliminated by the tangential tensile forces arising at the convex circumferential points. But this has also not led to any useful results, which is why, despite their excellent properties, compressed air radial motors based on the effect of such force cells have so far not been able to prevail. Compressed air radial motors of this type are described in detail in CH Patents 556,968 and 578,678.

Aufgabe der vorliegenden Erfindung ist nun die weitere Aus­gestaltung einer Kraftzellenanordnung der vorgenannten Art, derart, dass diese vergleichsweise den bisherigen Konstruk­tionen ein Mehrfaches an Leistung und Haltbarkeit erbringt, was gestattet, optimale Ergebnisse an einem Druckluft-Radial­motor bezüglich Anlaufverhalten, hohem Drehmoment, Leistungs­maximum, lastunabhängiger Drehzahl u. dgl. zu erzielen.The object of the present invention is the further development of a power cell arrangement of the aforementioned type, such that it provides a multiple in terms of performance and durability compared to the previous designs, which allows optimal results on a pneumatic radial motor with regard to starting behavior, high torque, maximum power, more load-independent Speed u. To achieve.

Dies wird erfindungsgemäss dadurch erreicht, dass sich ent­lang der Zellen-Peripherien eine, zwischen den beiden Kunst­stoff-Folienblättern eingelegte unendliche, gummielastische Schnur erstreckt, die sich nahe dem Rotationszentrum in sternförmiger Anordnung befindet, wobei die beiden Kunst­stoff-Folienblätter beidseitig der Schnur und diese voll­ständig umschliessend miteinander verschweisst sind.This is achieved according to the invention in that an infinite, rubber-elastic cord, which is inserted between the two plastic foil sheets and extends near the center of rotation in a star-shaped arrangement, extends along the cell peripheries, the two plastic foil sheets on both sides of the cord and this completely are welded together.

Durch diese Massnahmen wird jede einzelne Zelle von der gum­mielastischen Schnur quasi rundum armiert, wobei die Schnur praktisch alle bisher wirksamen peripheren Kräfte aufnimmt, was zu einem optimalen Balg-Verhalten der Zelle führt, womit deren Lebensdauer und Funktionsfähigkeit bisher nicht ver­mutete Grössenordnungen erreicht. Zudem lässt sich die er­findungsgemässe Kraftzellenanordnung ohne weiteres nach den Regeln der Massenfabrikation herstellen und steht so den An­wendern in beliebigen Mengen zur Verfügung.Through these measures, each individual cell is reinforced almost all around by the rubber-elastic cord, the cord absorbing practically all previously effective peripheral forces, which leads to an optimal bellows behavior of the cell, with which its lifespan and functionality reach dimensions not previously assumed. In addition, the power cell arrangement according to the invention can be easily manufactured according to the rules of mass production and is thus available to users in any quantity.

Zudem können die sich nahe dem Rotationszentrum befindlichen, durch die gummielastische Schnur bewirkten sternförmigen Er­hebungen Mittel einer formschlüssigen Mitnahmeverbindung bil den.In addition, the star-shaped elevations, which are located near the center of rotation and are caused by the rubber-elastic cord, can form a form-fitting entrainment connection.

Entsprechend betrifft die vorliegende Erfindung weiter die Verwendung der erfindungsgemässen Kraftzellenanordnung in einem Druckluft-Radialmotor mit einer rotierenden flachen Stützscheibe und einer, von der Antriebswelle getragenen ko­nischen Stützscheibe, zwischen welchen sich die Kraftzellen­anordnung befindet.Accordingly, the present invention further relates to the use of the force cell arrangement according to the invention in a compressed air radial motor with a rotating flat support disc and a conical support disc carried by the drive shaft, between which the force cell arrangement is located.

Erfindungsgemäss sind hierbei die sich nahe dem Rotations­zentrum befindlichen, durch die gummielastische Schnur be­wirkten sternförmigen Erhebungen der Kraftzellenanordnung in entsprechende Nuten in der Stirnseite der flachen Stützschei­be zur Herstellung einer formschlüssigen Drehmitnahmeverbin­dung abgesenkt.According to the invention, the star-shaped elevations of the force cell arrangement, which are located near the center of rotation and are caused by the rubber-elastic cord, are lowered into corresponding grooves in the end face of the flat support disk in order to produce a positive rotary connection.

Dadurch ist es nunmehr unnötig, die Kraftzellenanordnung, wie bisher, auf die flache Stützscheibe aufzukleben, was erlaubt, die Kraftzellenanordnung jederzeit und ohne Aufwand auszu­wechseln.As a result, it is now unnecessary to stick the force cell arrangement onto the flat support disk, as before, which allows the force cell arrangement to be replaced at any time and without effort.

Beispielsweise Ausführungsformen des Erfindungsgegenstandes sind nachfolgend anhand der Zeichnung näher erläutert.For example, embodiments of the subject matter of the invention are explained in more detail below with reference to the drawing.

Es zeigen:

  • Fig. 1 in Draufsicht und schematischer Darstellung eine erfindungsgemässe Kraftzellenanordnung;
  • Fig. 2 einen Schnitt entlang der Linie II - II in Fig. 1; und
  • Fig. 3 in einer Schnittdarstellung einen Druckluft-Radial­motor mit einer Kraftzellenanordnung gemäss den Fig. 1 und 2.
Show it:
  • 1 shows a top view and schematic representation of a power cell arrangement according to the invention;
  • FIG. 2 shows a section along the line II-II in FIG. 1; and
  • 3 shows a sectional view of a pneumatic radial motor with a force cell arrangement according to FIGS. 1 and 2.

Die Kraftzellenanordnung gemäss Fig. 1 und 2 umfasst hier drei, rosettenförmig zueinander angeordnete, in drucklosem Zustand angenähert ebene, zum wechselseitigen Aufblasen mit Luftanschlussmitteln 5,5′ versehene Kraftzellen 4,4′,4˝, die durch Verschweissung von zwei Kunststoff-Folienblätter 1 und 2 entlang der Zellen-Peripherien gebildet sind.The force cell arrangement according to FIGS. 1 and 2 here comprises three, in the form of a rosette, approximately flat in the depressurized state, for mutual inflation with air connection means 5,5 'provided with force cells 4,4', 4˝, which by welding two plastic film sheets 1 and 2 are formed along the cell peripheries.

Soweit sind solche Kraftzellenanordnungen bekannt, wobei die Anzahl und radiale Ausdehnung der Zellen natürlich variiert werden kann.So far, such force cell arrangements are known, although the number and radial expansion of the cells can of course be varied.

Erfindungswesentlich ist nun, dass sich entlang der Zellen-­Peripherien eine, zwischen den beiden Kunststoff-Folienblät­tern 1 und 2 eingelegte unendliche, gummielastische Schnur 3 erstreckt, die sich nahe dem Rotationszentrum in sternförmi­ger Anordnung befindet, wobei die beiden Kunststoff-Folien­blätter 1 und 2 beidseitig der Schnur 3 und diese vollstän­dig umschliessend miteinander verschweisst sind, wie dies durch die Schweisslinien 6,6′ angedeutet ist.It is essential to the invention that along the cell peripheries there is an infinite, rubber-elastic cord 3 inserted between the two plastic film sheets 1 and 2 extends, which is close to the center of rotation in a star-shaped arrangement, the two plastic film sheets 1 and 2 on both sides of the cord 3 and these are completely sealed together, as indicated by the welding lines 6,6 '.

Der Querschnitt der Schnur 3 kann beliebig sein. Vorzugswei­se kann die Schnur 3 durch Ausstanzung hergestellt werden, womit sich dann ein rechteckförmiger Querschnitt ergibt. Die Fähigkeit der Schnur zum Kräfteausgleich an der Zelle wird dadurch nicht beeinflusst.The cross section of the cord 3 can be any. The cord 3 can preferably be produced by punching out, which then results in a rectangular cross section. This does not affect the ability of the cord to balance forces on the cell.

Von wesentlicher Bedeutung ist dabei, dass die sich nahe dem Rotationszentrum befindlichen, durch die gummielastische Schnur 3 bewirkten sternförmigen Erhebungen 3′ Mittel einer formschlüssigen Mitnahmeverbindung bilden, wie dies nachfol­gend noch näher erläutert wird.It is essential that the star-shaped elevations 3 'located near the center of rotation, caused by the rubber-elastic cord 3' form a form-fit entrainment connection, as will be explained in more detail below.

Der in Fig. 3 schematisch gezeigte, ansich bekannte Druck­luft-Radialmotor umfasst zwei, in der Regel leicht vonein­ander trennbare Gehäuseteile 10,10′, in deren Kammer sich eine rotierende flache Stützscheibe 11 erstreckt, deren Ro­tationsachse 12 mit einer Antriebswelle 13 einen, der Koni­zität einer mit der Antriebswelle 13 verbundenen konischen Stützscheibe 14 entsprechenden Winkel einschliesst.The schematically shown in Fig. 3, known pneumatic radial motor comprises two, usually easily separable housing parts 10,10 ', in the chamber of which a rotating flat support plate 11 extends, the axis of rotation 12 with a drive shaft 13 one, the taper a conical support disk 14 connected to the drive shaft 13 includes a corresponding angle.

Auf der flachen Stützscheibe 11 stützt sich die erfindungs­gemässe Kraftzellenanordnung ab, wobei die sich nahe dem Ro­tationszentrum befindlichen, durch die gummielastische Schnur 3 bewirkten sternförmigen Erhebungen 3′ in entspre­chende Nuten 15 in der Stirnseite der Stützscheibe 11 abge­senkt sind, was eine radial vergrösserte formschlüssige Drehmitnahmeverbindung zwischen Kraftzellenanordnung und flacher Stützscheibe 11 gewährleistet. Zudem sitzen die Luft­anschlusshülsen 5′ in entsprechenden Anschlussbohrungen 16 in der Stützscheibe 11 ein, welche über den Verteiler 17 mit einer nicht näher gezeigten Druckquelle in Verbindung stehen.On the flat support plate 11, the power cell arrangement according to the invention is supported, the star-shaped elevations 3 'located near the center of rotation caused by the rubber-elastic cord 3' being lowered into corresponding grooves 15 in the end face of the support plate 11, which results in a radially enlarged positive-locking rotary connection between Load cell arrangement and flat support plate 11 ensured. In addition, the air connection sleeves 5 'sit in corresponding connection bores 16 in the support disk 11, which are connected via the distributor 17 to a pressure source, not shown in detail.

Dadurch ist es unnötig, die Kraftzellenanordnung, wie bisher, auf die flache Stützscheibe aufzukleben, was nun erlaubt, die Kraftzellenanordnung jederzeit und ohne Aufwand auszu­wechseln.As a result, it is unnecessary to stick the force cell arrangement onto the flat support disk as before, which now allows the force cell arrangement to be replaced at any time and without effort.

Mit der konischen Stützscheibe 14 steht die Kraftzellenan­ordnung weiterhin nur in Wirkungsverbindung.The force cell arrangement is still only in operative connection with the conical support disk 14.

Die Wirkungsweise solcher Druckluft-Radialmotoren ist bekannt. Um den Motor in Betrieb zu setzen, wird Druckmedium, z.B. Druckluft, durch den Verteiler 17 zugeleitet. Dieses Druckme­dium gelangt in die momentan angesteuerte Kraftzelle 4, wel­che ihr Volumen vergrössert hat. Dadurch resultiert infolge der beschriebenen Anordnung der beiden Stützscheiben 11 und 14 ein dem Druck entsprechendes Drehmoment auf die konische Stützscheibe 14, so dass diese, zusammen mit der flachen Stützscheibe 11, rotiert.The mode of operation of such pneumatic radial motors is known. In order to start the engine, pressure medium, for example compressed air, is supplied through the distributor 17. This pressure medium arrives in the currently activated power cell 4, which has increased its volume. This results in the arrangement of the two support disks 11 and 14 a torque corresponding to the pressure on the conical support disk 14 so that it rotates together with the flat support disk 11.
