Description

Die Erfindung betrifft ein Aufzugssystem mit einem Antrieb, der über ein Übertragungsmittel mit einer Aufzugkabine und einem Gegengewicht zusammenwirkt, um die Aufzugkabine und das Gegengewicht durch Übertragung einer Kraft in einem Aufzugschacht zu bewegen.The invention relates to an elevator system with a drive, which cooperates via a transmission means with an elevator car and a counterweight to move the elevator car and the counterweight by transmitting a force in an elevator shaft.

Aufzugssysteme dieser Art weisen üblicherweise eine Aufzugkabine auf, die in einem Aufzugschacht oder frei entlang einer Führungseinrichtung bewegbar ist. Zum Erzeugen der Bewegung weist das Aufzugssystem einen Antrieb auf, der über Übertragungsmittel mit der Aufzugkabine und einem Ausgleichsgewicht (auch Gegengewicht genannt) zusammenwirkt.Elevator systems of this type usually have an elevator car which is movable in an elevator shaft or freely along a guide device. To generate the movement, the elevator system has a drive, which interacts via transmission means with the elevator car and a balance weight (also called a counterweight).

Man unterscheidet Aufzugssysteme, bei denen Stahlseile runden Querschnitts als Übertragungsmittel eingesetzt werden und neuere Aufzugssysteme, die flache Riemen als Übertragungsmittel aufweisen.A distinction is made between elevator systems in which steel cables of round cross-section are used as transmission means and newer elevator systems which have flat belts as transmission means.

Ein Beispiel eines Aufzugssystems mit flachem Übertragungsmittel ist aus der PCT-Patentanmeldung WO 99/43602 bekannt. Die Aufzugkabine gemäss dieser Patentanmeldung wird durch einen Antrieb bewegt, der an dem Ausgleichsgewicht sitzt und sich solidarisch mit dem Gewicht bewegt.An example of a flat transmission elevator system is shown in FIG PCT Patent Application WO 99/43602 known. The elevator car according to this patent application is moved by a drive, which on the Balance weight sits and moves in solidarity with the weight.

Das beschriebene System hat den Nachteil, dass der als Übertragungsmittel verwendete Riemen nicht das mit bestimmten anderen riemenartigen Übertragungsmitteln erreichbare optimale Traktionsverhalten aufweist, und dass die Energiezufuhr zum Antriebsmotor wie auch die Übertragung von Signalen von zugehörigen Steuer- und Regelungseinrichtungen über lange, flexible Kabel erfolgen muss.The system described has the disadvantage that the belt used as a transmission means does not have the optimum traction behavior achievable with certain other belt-type transmission means, and that the power supply to the drive motor as well as the transmission of signals from associated control and regulation devices must be made over long, flexible cables ,

Ein weiteres Aufzugssystem mit zahnriemenartigem Übertragungsmittel ist aus der PCT-Patentanmeldung WO 99/43592 bekannt. Bei der beschriebenen und beanspruchten Anordnung ist der Antrieb im Gegengewicht integriert, und ein im Aufzugschacht fixiertes zahnriemenartiges Übertragungsmittel dient zum Übertragen der Antriebskraft zwischen Gegengewicht und Aufzugsschacht. Da die Aufzugkabine und das Ausgleichgewicht an einem vom genannten zahnriemenartigen Übertragungsmittel getrennten eigentlichen Tragmittel hängen, übertragen Antrieb und Übertragungsmittel nur die Differenzkraft zwischen dem Gegengewicht dem Gewicht der Aufzugkabine.Another elevator system with zahnriemenartigem transmission means is from the PCT Patent Application WO 99/43592 known. In the described and claimed arrangement, the drive is integrated in the counterweight, and a timing belt-like transmission means fixed in the elevator shaft serves to transmit the driving force between the counterweight and the elevator shaft. Since the elevator car and the balance weight depend on an actual suspension element separate from said timing belt transmission means, the drive and transmission means transmit only the differential force between the counterweight and the weight of the elevator car.

Dieses System weist dieselben Nachteile auf, wie das vorstehend beschriebene und hat den zusätzlichen Nachteil, dass für die Antriebsfunktion ein Zahnriemen und für die Tragfunktion ein anderes Mittel zum Einsatz kommen. Im Vergleich mit einem System, bei dem Antriebs- und Tragfunktion über dasselbe Mittel erfolgt, ist bei diesem System auch eine grössere Anzahl von Rollen oder Pulleys erforderlich.This system has the same disadvantages as described above and has the additional disadvantage that a toothed belt is used for the drive function and another means for the support function. Compared to a system where the drive and support functions are done by the same means, this system requires a larger number of pulleys or pulleys.

Ein andersartiges Aufzugssystem mit zahnriemenartigem Übertragungsmittel ist aus dem US-Patent 5,191,920 bekannt. In dem gezeigten Aufzugsystem steht das zahnriemenartige Übertragungsmittel im Aufzugschacht still. Die Antriebseinheit befindet sich an der Aufzugkabine bzw. an dem sogenannten Lastaufnahmemittel.A different elevator system with timing belt-like transmission means is from the U.S. Patent 5,191,920 known. In the elevator system shown, the timing belt-like transmission means is stationary in the elevator shaft. The drive unit is located on the elevator car or on the so-called load-receiving means.

Dieses System weist daher dieselben Nachteile auf, wie das in WO 99/43602 beschriebene. Ein zusätzlicher Nachteil ist hier, dass durch den Aufzugsantrieb das Gewicht des Lastaufnahmemittels und somit die erforderliche Antriebsleistung erhöht wird.This system therefore has the same disadvantages as that in WO 99/43602 described. An additional disadvantage here is that the weight of the load receiving means and thus the required drive power is increased by the elevator drive.

WO2002/059028 ( FI4928U1 )offenbart ein Aufzugssystem mit einem Antrieb, der über ein Übertragungsmittel mit einer Aufzugskabine und einem Gegengewicht zusammenwirkt, um die Kabine und das Gegengewicht durch Übertragung einer Kraft in einem Aufzugsschacht zu bewegen. Als Aufhängung ist eine Aufhängungsordnung grösser 2:1 gewählt. Der Antrieb ist mit einem Antriebspulley versehen und wird von einer oben im Aufzugsschacht angeordnete Tragstruktur getragen, ebenso wie weitere Umlenkpulleys, die für die hohe Aufhängungsordnung nötig sind. Das Übertragungsmittel ist über das Antriebspulley, über verschiedene Umlenkpulleys, über ein Tragpulley der Aufzugskabine und ein Tragpulley des Gegengewichts geführt. Seine beiden Enden sind an Fixpunkten im Bereich der Tragstruktur befestigt. Durch die Wahl der grossen Aufhängungsordnung sind die durch den Antrieb zu bewegenden Gewichte verhältnismässig gering, was die Wahl eines kleinen Antriebs ermöglicht. Diese Platzeinsparung wird aber durch die grosse Anzahl Umlenkpulleys und deren Platzbedarf wieder aufgehoben. WO2002 / 059028 ( FI4928U1 ) discloses an elevator system having a drive which cooperates via a transmission means with an elevator car and a counterweight to move the car and the counterweight by transmitting a force in a hoistway. As a suspension, a suspension order greater than 2: 1 is selected. The drive is provided with a drive pulley and is carried by a support structure arranged at the top in the elevator shaft, as well as further deflection pulleys, which are necessary for the high suspension order. The transfer means is guided via the drive pulley, via different deflection pulleys, via a carrying pulley of the elevator car and a carrying pulley of the counterweight. Its two ends are attached to fixed points in the region of the support structure. By choosing the large suspension order to be moved by the drive weights are relatively low, which allows the choice of a small drive. This space saving is offset by the large number of deflection pulleys and their space requirement again.

WO 1999/43593 stellt sich ebenfalls die Aufgabe Platz zu sparen und die Verwendung eines kleineren Antriebs zu ermöglichen. Hierfür ist ein Aufzugssystem mit einer 2:1 Aufzugsaufhängung mit einem flachen riemenartigen Übertragungsmittel offenbart. Das Übertragungsmittel ist seitlich der Kabinenwand über eine Antriebsscheibe eines Antriebs, eine unterhalb des Antriebs angeordnete Umlenkrolle und jeweils eine Umlenktragrolle der Kabine und eine Umlenktragrolle des Gegengewichts geführt. WO 1999/43593 also sets itself the task of saving space and to allow the use of a smaller drive. For this purpose, an elevator system with a 2: 1 elevator suspension with a flat belt-type transmission means is disclosed. The transmission means is guided laterally of the cabin wall via a drive pulley of a drive, a deflection pulley arranged below the drive, and in each case a deflection roller of the car and a deflection roller of the counterweight.

Die in den genannten Dokumenten offenbarten Riemen weisen gewisse Nachteile auf. Flachriemen haben in Aufzugseinrichtungen mit im Verhältnis zur Nutzlast leichten Aufzugkabinen eine ungenügende Traktionsfähigkeit. Bei Zahnriemen besteht das Problem, dass diese nicht auf dem Antriebspulley rutschen, wenn die Aufzugkabine oder das Gegengewicht infolge einer Steuerungspanne auf ihren Endlagenpuffern aufliegen. Ausserdem ist die Zentrierung des Riemens auf den Riemenpulleys nicht problemlos zu realisieren. Es müssen gegebenenfalls spezielle Massnahmen an den Pulleys getroffen werden, um zu verhindern, dass der Riemen aus der zentralen Lage heraus läuft.The belts disclosed in the cited documents have certain disadvantages. Flat belts have insufficient traction capability in elevator facilities with elevator cabins that are lightweight relative to the payload. The problem with timing belts is that they do not slip on the drive pulley when the elevator car or counterweight is resting on its limit buffers due to a control failure. In addition, the centering of the belt on the Riemenpulleys is not easy to implement. Special measures may need to be taken on the pulleys to prevent the belt from running out of the central position.

Die Aufgabe der Erfindung wird somit darin gesehen, ein verbessertes Aufzugssystem der eingangs genannten Art zu schaffen, welches Nachteile der bekannten Systeme reduziert oder vermeidet.The object of the invention is thus seen to provide an improved elevator system of the type mentioned, which reduces or avoids the disadvantages of the known systems.

Die Lösung dieser Aufgabe ist in den Patentansprüchen definiert.The solution to this problem is defined in the patent claims.

Das erfindungsgemässe Aufzugssystem weist eine Aufzugkabine, einen Antrieb, riemenartige Übertragungsmittel, vorzugsweise einen Keilrippen-Riemen, und ein Gegengewicht auf. Der Antrieb ist stationär und die Übertragungsmittel wirken mit dem Antrieb zusammen, um die Aufzugkabine durch Übertragung einer Kraft zu bewegen.The elevator system according to the invention comprises an elevator car, a drive, belt-like transmission means, preferably a V-ribbed belt, and a counterweight. The drive is stationary and the transfer means cooperate with the drive to move the elevator car by transmitting a force.

Detaillierte BeschreibungDetailed description

In den folgenden Ausführungsformen kommen vorzugsweise sogenannte Keilrippen-Riemen - auch Keilrippenriemen genannt - zum Einsatz. Ein solcher Keilrippen-Riemen kann vorteilhafterweise als reibschlüssiges (haftschlüssiges) Trag- und/oder Antriebselement (Übertragungsmittel) für eine Aufzugkabine mit Gegengewicht eingesetzt werden. Der Keilrippen-Riemen ermöglicht, bei ähnlichen Laufeigenschaften wie ein Flachriemen, durch seine Form ein höheres Seilkraftverhältnis. Im Falle eines durch ein Riemenpulley angetriebenen Riemens bedeutet ein hohes Seilkraftverhältnis, dass die Zugkraft im auf das Riemenpulley auflaufenden (gezogenen) Trum des Riemens wesentlich höher sein kann, als im gleichzeitig vom Riemenpulley ablaufenden Trum. Bei der Anwendung eines Keilrippen-Riemen als Übertragungsmittel für eine Aufzugkabine mit Gegengewicht wirkt sich dieser Vorteil darin aus, dass auch eine sehr leichtgebaute Aufzugkabine mit einem viel schwereren Gegengewicht zusammenwirken kann, ohne dass das Übertragungsmittel auf dem Antriebspulley rutscht.In the following embodiments are preferably so-called V-ribbed belts - also called V-ribbed belts - are used. Such a V-ribbed belt can advantageously be used as a frictional (adhesive) support and / or drive element (transmission means) for an elevator car with counterweight. The V-ribbed belt allows, with similar running characteristics as a flat belt, by its shape a higher rope force ratio. In the case of a belt driven by a belt pulley, a high rope force ratio means that the tension in the belt pulley running (pulled) strand of the belt can be substantially higher than in the belt running from the belt pulley at the same time. When using a V-ribbed belt as a transfer means for a counterweight elevator car, this advantage has the effect that even a very lightweight elevator car can interact with a much heavier counterweight without the transfer means slipping on the drive pulley.

Wie in den Fig. 13 bis 15 gezeigt, weist der Keilrippen-Riemen 13 mehrere in Längsrichtung parallel angeordnete keilförmige Rillen 5 und Keilrippen 6 auf. Diese keilförmigen Rillen 5 und Keilrippen 6 ermöglichen durch ihre Keilwirkung ein Seilkraftverhältnis von mehr als 2 bei einem Umschlingungswinkel von 180 Grad.As in the Fig. 13 to 15 shown, the V-ribbed belt 13 a plurality of longitudinally parallel wedge-shaped grooves 5 and V-ribs 6. These wedge-shaped grooves 5 and V-ribs 6 allow by their wedge effect a cable force ratio of more than 2 at a wrap angle of 180 degrees.

Es ist ein weiterer Vorteil des Keilrippen-Riemens 13, dass er sich auf den ihn antreibenden oder führenden Pulleys selbst zentriert vorzugsweise wird der Keilrippen-Riemen 13 auf der Rückseite (d.h. auf der Seite, die keine keilförmigen Rillen 5 bzw. Keilrippen 6 aufweist) mit einer Führungsrippe 2 versehen, wie in Fig. 15 gezeigt. Diese Führungsrippe 2 hat die Aufgabe, bei einer Gegenbiegung des Keilrippen-Riemens, d. h., wenn dieser ein Pulley mit gegen das Pulley gerichteter Riemen-Rückseite umläuft, den Keilrippen-Riemen in einer in der Lauffläche des Pulleys vorhandenen Führungsrille zu führen.It is a further advantage of the V-ribbed belt 13 that it centers itself on the pulley driving or guiding it itself, preferably the V-ribbed belt 13 on the rear side (ie on the side which has no wedge-shaped grooves 5 or V-ribs 6) provided with a guide rib 2, as in Fig. 15 shown. This guide rib 2 has the task in a counter-bending of the V-ribbed belt, that is, when this rotates a pulley with directed against the pulley belt back, to guide the V-ribbed belt in an existing in the running surface of the pulley guide groove.

Für die erfindungsgemässe Anwendung ist es von Vorteil, wenn die keilförmigen Rillen 5 der Keilrippen-Riemen 13 einen Rillenwinkel b von 80 Grad bis 100 Grad aufweisen. Vorzugsweise beträgt der Rillenwinkel b ca. 90 Grad. Dieser Rillenwinkel b ist wesentlich grösser als bei herkömmlichen Keilrippen-Riemen. Durch den grösseren Rillenwinkel b erreicht man eine Reduktion des Laufgeräusches. Die selbstzentrierende Eigenschaft wie auch ein (vorstehend definiertes) erhöhtes Seilkraftverhältnis bleiben aber erhalten.For the application according to the invention, it is advantageous if the wedge-shaped grooves 5 of the V-ribbed belts 13 have a groove angle b of 80 degrees to 100 degrees. Preferably, the groove angle b is about 90 degrees. This groove angle b is much larger than in conventional V-ribbed belts. The larger groove angle b achieves a reduction of the running noise. The self-centering property as well as an increased cable force ratio (defined above) are retained.

In einer weiteren Ausführungsform ist der Keilrippen-Riemen 13 auf der Rückseite, wie in Fig. 13 gezeigt, mit einer Schicht 4 versehen, die vorzugsweise gute Gleiteigenschaften hat. Diese Schicht 4 kann zum Beispiel eine Gewebeschicht sein. Bei mehrfach umgehängten Aufzugssysteme erleichtert dies die Montage.In another embodiment, the V-ribbed belt 13 is on the backside, as in FIG Fig. 13 shown provided with a layer 4, which preferably has good sliding properties. This layer 4 may be, for example, a fabric layer. For multiple suspended elevator systems this facilitates the assembly.

Ein weiterer Keilrippen-Riemen 13 ist in Fig. 14 gezeigt. Dieser Keilrippen-Riemen hat sowohl keilförmige Rillen 5 und Rippen 6, die in Längsrichtung angelegt sind, als auch Querrillen 3. Diese Querrillen 3 verbessern die Biegeflexibilität des Keilrippen-Riemens, so dass dieser mit Riemenpulleys mit reduziertem Durchmesser zusammenwirken kann.Another V-ribbed belt 13 is in Fig. 14 shown. This V-ribbed belt has both wedge-shaped grooves 5 and ribs 6 applied longitudinally, as well as lateral grooves 3. These transverse grooves 3 enhance the bending flexibility of the V-ribbed belt so that it can interact with reduced diameter belt pulleys.

In den Fig. 13, 14 und 15 ist auch zu erkennen, dass das Übertragungsmittel (Keilrippen-Riemen 13) in dessen Längsrichtung orientierte Zugträger 1 enthält, die aus metallischen Litzen (z.B. Stahllitzen) oder nicht-metallischen Litzen (z.B. aus Chemiefasern) bestehen. Solche Zugträger 1 verleihen den erfindungsgemässen Übertragungsmitteln die erforderliche Zugfestigkeit und/oder Längssteifigkeit. Eine bevorzugte Ausführungsform der Übertragungsmittel enthält Zugträger 1 aus Zylon-Fasern. Zylon ist ein Handelsname der Firma Toyobo Co. Ltd., Japan, und betrifft Chemiefasern aus Poly(p-phenylene-2,6-benzobisoxazole) (PBO). Diese Fasern übertreffen in den für die erfindungsgemässe Anwendung entscheidenden Eigenschaften diejenigen von Stahllitzen und von anderen bekannten Fasern. Die Längsdehnung und das Metergewicht des Übertragungsmittels können durch die Verwendung von Zylon-Fasern reduziert werden, wobei die Bruchkraft gleichzeitig höher ausfällt.In the FIGS. 13, 14 and 15 can also be seen that the transmission means (V-ribbed belt 13) in the longitudinal direction oriented tensile carrier 1 contains, from Metallic strands (eg steel strands) or non-metallic strands (eg made of chemical fibers) exist. Such tension members 1 impart the required tensile strength and / or longitudinal rigidity to the transfer means according to the invention. A preferred embodiment of the transmission means comprises tension members 1 made of Zylon fibers. Zylon is a trade name of Toyobo Co. Ltd., Japan, and refers to manmade fibers of poly (p-phenylene-2,6-benzobisoxazole) (PBO). These fibers surpass those of steel strands and other known fibers in the properties which are decisive for the application according to the invention. The elongation and the meter weight of the transfer means can be reduced by the use of Zylon fibers, whereby the breaking force is higher at the same time.

Idealerweise sollten die Zugträger 1 so im Keilrippen-Riemen eingebettet sein, dass sich benachbarte Fasern oder Litzen nicht berühren. Als ideal hat sich ein Füllungsgrad, d. h. ein Verhältnis zwischen dem Gesamtquerschnitt aller zugträger und dem Querschnitt des Riemens, von mindestens 20% erwiesen.Ideally, the tension members 1 should be embedded in the V-ribbed belt so that adjacent fibers or strands do not touch each other. The ideal is a degree of filling, d. H. a ratio between the total cross section of all tension members and the cross section of the belt, proven by at least 20%.

Fig. 16 zeigt eine als Übertragungsmittel für Aufzugssysteme ebenfalls geeignete Ausführungsform des Keilrippen-Riemens 13. Anstelle der im Zusammenhang mit Fig. 13-15 erwähnten zugträger aus metallischen oder nichtmetallischen Litzen, bildet hier eine flächige Zugschicht 51 den Kern des Keilrippen-Riemens 13, wobei diese Zugschicht 51 sich im Wesentlichen über die gesamte Riemenlänge und die gesamte Riemenbreite erstreckt. Die Zugschicht 51 kann aus einer unverstärkten Materialschicht, beispielsweise aus einer Polyamidfolie, bestehen, oder aus einer mit Chemiefasern verstärkten Folie gebildet sein. Fig. 16 shows an embodiment of the V-ribbed belt 13, which is likewise suitable as transmission means for elevator systems. Instead of those in connection with FIG Fig. 13-15 mentioned tensile carrier of metallic or non-metallic strands, here forms a flat tension layer 51 the core of the V-ribbed belt 13, said tension layer 51 extends substantially over the entire belt length and the entire belt width. The tension layer 51 can consist of an unreinforced material layer, for example of a polyamide film, or be formed of a film reinforced with synthetic fibers.

Eine solche verstärkte Folie könnte beispielsweise die vorstehend genannten Zylon-Fasern, eingebettet in eine geeignete Kunststoff-Matrix, enthalten.Such a reinforced film could, for example, contain the aforementioned Zylon fibers embedded in a suitable plastic matrix.

Die Zugschicht 51 verleiht dem Flachriemen die erforderliche Zug- und Kriechfestigkeit, ist aber auch genügend flexibel, um eine ausreichend hohe Zahl von Biegevorgängen beim Umlenken um ein Riemenpulley ertragen zu können.The tension layer 51 gives the flat belt the required tensile and creep resistance, but is also sufficiently flexible to withstand a sufficiently high number of bending operations when deflecting around a belt pulley.

Die Keilrippen-Schicht 53 kann beispielsweise aus Polyurethan oder aus einem NBR-Elastomer (Nitrile Butadiene Rubber) bestehen und ist ganz- oder teilflächig, direkt oder über eine Zwischenschicht mit der Zugschicht 51 verbunden. Die Rückseite des Keilrippen-Riemens weist eine wie die Keilrippen-Schicht mit der Zugschicht 51 verbundene Deckschicht 54 auf, die vorteilhafterweise als Gleitbelag ausgeführt ist.The V-ribbed layer 53 can be made, for example, of polyurethane or of an NBR elastomer (nitrile butadiene rubber) and is connected over the whole or part of the surface, directly or via an intermediate layer, to the tension layer 51. The back side of the V-ribbed belt has a cover layer 54 connected to the tension layer 51 like the V-ribbed layer, which is advantageously designed as a sliding covering.

Zwischen den genannten Haupt-Schichten können Zwischenschichten (hier nicht dargestellt) vorhanden sein, die die erforderliche Haftung zwischen den genannten Schichten vermitteln und/oder die Flexibilität des Übertragungsmittels erhöhen. Dieser mit einer ganzflächigen Zugschicht versehene Keilrippen-Riemen kann auch eine wie bereits im Zusammenhang mit Fig. 15 beschriebene Führungsrippe aufweisen.Intermediate layers (not shown) may be present between said major layers to provide the necessary adhesion between said layers and / or increase the flexibility of the transfer medium. This provided with a full-area tension layer V-ribbed belt can also be as already associated with Fig. 15 have described guide rib.

In Fig. 17 ist ein weiteres in Aufzugssystemen anwendbares Übertragungsmittel dargestellt, das sich zur Lösung der erfindungsgemässen Aufgabe eignet. Es handelt sich dabei um einen aus mehreren Schichten unterschiedlicher Materialien aufgebauten Flachriemen 50. Der Flachriemen enthält im Kern wenigstens eine flächige Zugschicht 51, die beispielsweise aus einer unverstärkten Polyamidfolie besteht, oder aus einer Kunststoff-Folie, die mit in die Kunststoffmatrix eingebetteten Chemiefasern verstärkt ist. Diese Zugschicht 51 verleiht dem Flachriemen die erforderliche Zug- und Kriechfestigkeit, ist aber auch genügend flexibel, um eine ausreichend hohe Zahl von Biegevorgängen beim Umlenken um ein Riemenpulley ertragen zu können. Der Flachriemen 50 weist ausserdem eine äussere, vorderseitige Reibschicht 55, beispielsweise aus einem NBR-Elastomer (Nitrile Butadiene Rubber) auf, sowie eine äussere, rückseitige Deckschicht 54, die, je nach Aufzugssystem, als Reib- oder Gleitbelag ausgeführt ist. Zwischen den genannten Haupt-Schichten können Zwischenschichten 56 vorhanden sein, die die erforderliche Haftung zwischen den genannten Schichten vermitteln und/oder die Flexibilität des Flachriemens erhöhen. Zwecks Optimierung des vorerwähnten Seilkraftverhältnisses sind Reibschichten mit Reibwerten von 0,5 bis 0,7 gegenüber Stahlpulleys verfügbar, die zudem sehr abriebbeständig sind.In Fig. 17 another transfer means which can be used in elevator systems is shown, which is suitable for the solution of the task according to the invention. It is a flat belt 50 composed of several layers of different materials. The flat belt contains at least one flat tensile layer 51 in the core, which, for example, is consists of an unreinforced polyamide film, or of a plastic film reinforced with chemical fibers embedded in the plastic matrix. This tension layer 51 gives the flat belt the required tensile and creep resistance, but is also sufficiently flexible to withstand a sufficiently high number of bending operations when deflecting around a belt pulley. The flat belt 50 also has an outer, front-side friction layer 55, for example made of an NBR elastomer (nitrile butadiene rubber), as well as an outer, back-side cover 54, which, depending on the elevator system, is designed as a friction or sliding coating. Intermediate layers 56 may be present between said main layers to provide the required adhesion between said layers and / or to increase the flexibility of the flat belt. In order to optimize the aforementioned rope force ratio friction layers are available with coefficients of friction of 0.5 to 0.7 compared to steel pulleys, which are also very resistant to abrasion.

Die seitliche Führung des Flachriemens 50 wird üblicherweise, wie in Fig. 18 dargestellt, durch an den Pulleys 16 angebrachte Bordscheiben 57 gewährleistet, eventuell in Kombination mit einer Bombierung der Pulley-Laufflächen.The lateral guidance of the flat belt 50 is usually, as in Fig. 18 represented, ensured by mounted on the pulleys 16 flanges 57, possibly in combination with a crowning of the pulley treads.

Eine Ausführungsform ist in den Fig. 6A und 6B gezeigte. Der Antrieb 14 ist oberhalb der Aufzug-Schachttüre 7 zwischen der Schachtinnenwand 21 und der Schachtaussenwand 22 angeordnet. Dies ist ohne weiteres möglich, da der Durchmesser des Antriebs 14 kleiner ist als die Schachtwanddicke D. Der Antrieb 14 kann wie bei den anderen Ausführungsformen als Synchron- oder Asynchronmotor ausgelegt sein. Vorteilhafterweise wird als Antrieb ein Kleinmassensystem, d. h. ein Antrieb mit geringem Massenträgheitsmoment, eingesetzt. Der Antrieb 14 ist an den beiden Enden je mit einem Antriebspulley 16.1 versehen. Sowohl die Antriebspulleys 16.1 als auch der Antrieb 14 können auf einem gemeinsamen Support 43 befestigt sein. Das System 10 ist mit zwei Gegengewichten 15 ausgestattet, die je auf einer Seite der Aufzugkabine 12 angeordnet sind. Die Keilrippen-Riemen-Übertragungsmittel 13 sind symmetrisch auf der linken und rechten Seite der Aufzugkabine 12 angeordnet. Erste Trums der Keilrippen-Riemen-Überträgungsmittel 13 führen von den Antriebspulleys 16.1 aus zu ersten auf gleicher Höhe fest montierten Umlenkpulleys 16.5, von diesen aus abwärts zu beidseitig an der Aufzugkabine 12 angebrachten Umlenkpulleys 16.6, umschlangen diese und führen aufwärts zu Fixpunkten 25.1. Zweite Trums der Keilrippen-Riemen-Übertragungsmittel 13 führen von den Antriebspulleys 16.1 aus zu zweiten auf gleicher Höhe fest montierten Umlenkpulleys 16.7, von diesen aus abwärts zu an den Gegengewichten 15 angebrachten Umlenkpulleys 16.8, umschlingen diese und führen aufwärts zu Fixpunkten 25.2. Oberhalb des vom Gegengewicht 15 in seiner obersten Lage beanspruchten Raums sind beidseits der Aufzugkabine 12 je ein Träger 44 auf den Gegengewichtsführungsschienen 19 und der Kabinenführungsschienen 18 montiert, welche Träger 44 die Umlenkpulleys 16.5 und 16.7, sowie die Fixpunkte 25.1 und 25.2 tragen. Die Träger 44 können mit dem Support 43 des Antriebs 14 eine u-förmige Tragstruktur bilden. Horizontal und vertikal wirkende Kräfte werden somit nicht auf die Schachtstruktur übertragen. Die Kabinenführungsschienen 18 und die!an der Aufzugkabine 12 befestigten Umlenkpulleys 16.6 sind in Richtung der Kabinentiefe so nahe wie möglich beim Kabinenschwerpunkt S angeordnet, damit die Führungskräfte im Normalbetrieb wie auch beim Fangen gering bleiben.An embodiment is in the Fig. 6A and 6B shown. The drive 14 is arranged above the elevator shaft door 7 between the shaft inner wall 21 and the shaft outer wall 22. This is readily possible because the diameter of the drive 14 is smaller than the shaft wall thickness D. The drive 14 may be designed as a synchronous or asynchronous motor as in the other embodiments. Advantageously, a small mass system, ie a drive with a low mass moment of inertia, is used as the drive. The drive 14 is provided at the two ends each with a Antriebspulley 16.1. Both the Antriebspulleys 16.1 and the drive 14 may be mounted on a common support 43. The system 10 is provided with two counterweights 15, each located on one side of the elevator car 12. The V-ribbed belt transmission means 13 are arranged symmetrically on the left and right sides of the elevator car 12. First strands of the V-ribbed belt transmission means 13 lead from the Antriebspulleys 16.1 to first at the same height fixed Umlenkpulleys 16.5, from these down to both sides of the elevator car 12 mounted Umlenkpulleys 16.6, embrace them and lead up to fixed points 25.1. Second runs of the V-ribbed belt transmission means 13 lead from the Antriebspulleys 16.1 to second at the same height firmly mounted Umlenkpulleys 16.7, of this from down to attached to the counterweights 15 Umlenkpulleys 16.8, wrap around them and lead up to fixed points 25.2. Above the space occupied by the counterweight 15 in its uppermost position, a carrier 44 is mounted on the counterweight guide rails 19 and the car guide rails 18 on both sides of the elevator car 12, which carriers 44 carry the deflecting pulleys 16.5 and 16.7 and the fixed points 25.1 and 25.2. The carriers 44 may form a U-shaped support structure with the support 43 of the drive 14. Horizontal and vertical forces are thus not transferred to the shaft structure. The car guide rails 18 and the deflection pulleys 16, 16 fastened to the elevator car 12 are arranged as close as possible to the car center of gravity S in the direction of the car depth so that the executives remain low during normal operation as well as when catching.

In Fig. 6C sind Details eines ersten Antriebs 14 gezeigt, der Bestandteil eines maschinenraumlosen Aufzugssystem gemäss den Fig. 6A und 6B ist. Der Antrieb 14 umfasst einen Motor 40 und einer oder zwei Bremsen 41. Die beiden Antriebspulleys 16.1 werden durch Trägerelemente 44 mit dem Support 43 verbunden. Isolierte Drehmomentstützen 42 dienen der Befestigung des Motors 40 an dem Support 43. Die Welle 45 ist durchgehend ausgeführt. Der gezeigte Antrieb hat geringe rotierende Massen und ist auf Grund seiner geringen Baugrösse zum Einbau in die Schachtwand geeignet.In Fig. 6C are shown details of a first drive 14, which is part of a machine room-less elevator system according to the Fig. 6A and 6B is. The drive 14 comprises a motor 40 and one or two brakes 41. The two drive pulleys 16. 1 are connected to the support 43 by carrier elements 44. Insulated torque arms 42 serve to secure the motor 40 to the support 43. The shaft 45 is continuous. The drive shown has low rotating masses and is suitable due to its small size for installation in the shaft wall.

In Fig. 6D sind Details eines zweiten Antriebs 14 gezeigt, der Bestandteil eines maschinenraumlosen Aufzugssystem gemäss den Fig. 6A und 6B ist. Der gezeigte Antrieb 14 hat eine geteilte Welle 46, die mit zwei Kupplungselementen 47 versehen ist. Ansonsten entspricht dieser Antrieb dem in Fig. 6C gezeigten Antrieb. Die Wartung des Antriebs 14 kann vom Schächtinneren aus erfolgen.In Fig. 6D are shown details of a second drive 14, which is part of a machine room-less elevator system according to the Fig. 6A and 6B is. The illustrated drive 14 has a split shaft 46 which is provided with two coupling elements 47. Otherwise, this drive corresponds to the in Fig. 6C shown drive. The maintenance of the drive 14 can take place from the inside of the shaft.

Eine Weiterbildung der Ausführungsform gemäss den Fig. 6A und 6B ist in den Fig. 7A und 7B gezeigt. Die Ausführungsform unterscheidet sich dadurch, dass zwei separate Antriebe 14.1 und 14.2 vorgesehen sind. Die Kabine 12 und die Gegengewichte 15 sind 2:1 aufgehängt. Die Seinenansicht in Figur 7B zeigt die stets gleichsinnige Biegung der Keilrippen-Riemen-Übertragungsmittel 13, was deren vorzeitiger Abnützung entgegenwirkt.A development of the embodiment according to the Fig. 6A and 6B is in the Figs. 7A and 7B shown. The embodiment differs in that two separate drives 14.1 and 14.2 are provided. The car 12 and the counterweights 15 are hung 2: 1. The view in FIG. 7B shows the always same direction bending of the V-ribbed belt transmission means 13, which counteracts their premature wear.

Ein weiterer kompakter Antrieb 14 ist in Fig. 12 gezeigt. Dieser Antrieb 14 zeichnet sich dadurch aus, dass er zwei Antriebspulleys 16.1 aufweist. Der Antrieb 14 umfasst weiterhin einen Motor 40, eine Bremse 41 und eine durchgehende Welle 45. Die beiden Antriebspulleys 16.1 sitzen je an einem Ende der Welle 45. Der Antrieb 14 ist besonders für den seitlich oberhalb der Kabine 12 liegenden Einbau ausgelegt.Another compact drive 14 is shown in FIG. This drive 14 is characterized in that it has two drive pulleys 16.1. The drive 14 further comprises a motor 40, a brake 41 and a continuous shaft 45. The two drive pulleys 16.1 each sit at one end of the shaft 45. The drive 14 is designed especially for the laterally above the car 12 lying installation.

In einer weiteren Ausführungsform weist der Keilrippen-Riemen Zähne auf, die hochverschleissfest ausgeführt sind.In a further embodiment, the V-ribbed belt has teeth which are made highly wear-resistant.

Gemäss Erfindung ist der stationäre Antrieb entweder in einem Maschinenraum untergebracht, oder der Antrieb befindet sich im bzw. am Aufzugschacht.According to the invention, the stationary drive is either housed in a machine room, or the drive is located in or on the elevator shaft.
