Definitions
- Elevator with belt-like transmission means in particular with V-ribbed belt, as suspension and / or propellant
- the invention relates to an elevator system with a Drive, via a transmission means with an elevator car and a counterweight cooperates with the elevator car and the counterweight by transmitting a force in to move an elevator shaft.
- Elevator systems of this type usually have an elevator car up in an elevator shaft or free along a guide device is movable. To generate the Movement, the elevator system has a drive over Transmission means with the elevator car and a balance weight (also called counterweight) interacts.
- a balance weight also called counterweight
- the described system has the disadvantage that the as Transmission means did not use that with certain belts achievable other belt-like transmission means has optimal traction and that the energy input to the drive motor as well as the transmission of Signals from associated control and regulating devices over long, flexible cables must be made.
- This system has the same disadvantages as the described above and has the additional disadvantage, that for the drive function, a toothed belt and for the Tragfunktion another means are used. in the Comparison with a system in the drive and support function done through the same means is in this system Also a larger number of roles or pulleys required.
- a different elevator system with toothed belt type Transfer agent is known from US Patent 5,191,920.
- the drive unit is located on the elevator car or on the so-called Load handling attachments.
- the belts disclosed in the cited documents have certain disadvantages.
- Flat belts have in elevator facilities with in relation to the payload light elevator cabins insufficient traction.
- the problem is that these are not on the drive pulley slip when the elevator car or the counterweight due to a control breakdown on its end position buffers rest.
- the centering of the belt on the Riemenpulleys not easy to realize.
- 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.
- the elevator system has an elevator car, a drive, belt-like transmission means, preferably a V-ribbed belt, and a counterweight on.
- a drive preferably a V-ribbed belt
- a counterweight on.
- the transmission means participate the drive together to the elevator car through transmission to move a force.
- V-ribbed belts - also called V-ribbed belts - for use.
- Such a V-ribbed belt can advantageously as frictionally engaged (adhesive) and / or drive element (transmission means) for a Elevator cab be used with counterweight.
- a higher one by its shape Cable force ratio In the case of a belt pulley driven belt means a high rope force ratio, that the tensile force in running on the belt pulley (pulled) run of the belt can be much higher than in the same time running from Riemenpulley strand.
- a V-ribbed belt as transmission means for an elevator car with counterweight has this advantage It also makes a very light elevator car can interact with a much heavier counterweight without the transmission means on the Antriebspulley slips.
- the V-ribbed belt 13 has a plurality of wedge-shaped grooves 5 and V-ribs 6 arranged in parallel in the longitudinal direction. 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.
- the V-ribbed belt 13 that it centers itself on the pulleys driving or guiding it.
- the V-ribbed belt 13 on the back side (that is, on the side having no wedge-shaped grooves 5 or V-ribs 6) is provided with a guide rib 2, as shown in FIG .
- This guide rib 2 has the task, in a reverse bending of the V-ribbed belt, ie, when this rotates a pulley with directed against the pulley belt back, to guide the V-ribbed belt in a present in the running surface of the pulley guide groove.
- the wedge-shaped grooves 5 of the V-ribbed belt 13 a Groove angle b of 80 degrees to 100 degrees.
- the groove angle b is about 90 degrees.
- This groove angle b is much larger than conventional V-ribbed belts. Achieved by the larger groove angle b a reduction of the running noise.
- the self-centering Property as well as one (defined above) increased rope power ratio remain but.
- the V-ribbed belt 13 on the rear side, as shown in Fig. 13 is provided with a layer 4, which preferably has good sliding properties.

- V-ribbed belt 13 is shown in FIG .
- 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 flexing flexibility of the V-ribbed belt so that it can cooperate with reduced diameter belt pulleys.
- the transmission means (V-ribbed belt 13) contains tension members 1 oriented in the longitudinal direction, which consist of metallic strands (eg steel strands) or non-metallic strands (eg of manmade fibers) , Such tension members 1 impart the required tensile strength and / or longitudinal rigidity to the transfer means according to the invention.

- 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. Such a reinforced film could, for example, contain the aforementioned Zylon fibers embedded in a suitable plastic matrix.
- 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.
- 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 rear 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. 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.

Eine bevorzugte Ausführungsform der Übertragungsmittel enthält Zugträger 1 aus Zylonfasern. 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.
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.
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. 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.
Die durch die beiden Kabinenführungsschienen 18 gebildete Führungsebene 20 ist, wie in Fig. 1B gezeigt, gegenüber dem unter der Aufzugkabine 12 hindurchführenden Strang des Keilrippen-Riemen-Übertragungsmittel 13, d. h. gegenüber der Querachse der Aufzugkabine 12, um einem Winkel a von 15 bis 20 Grad verdreht angeordnet. Dadurch können die Kabinenführungsschienen ausserhalb des vom Keilrippen-Riemen-Übertragungsmittel 13 und den Riemenpulleys beanspruchten Raums platziert werden, wodurch erreicht wird, dass einerseits die Achse des unter der Aufzugkabine 12 hindurchführenden Strangs des Keilrippen-Riemen-Übertragungsmittel 13 unterhalb des Kabinenschwerpunkts S angeordnet werden kann, wenn dieser in der durch die Kabinenführungsschienen 18 gebildete Führungsebene 20 liegt. Ausserdem wird damit die beanspruchte Schachtbreite minimiert.
