Description

Die vorliegende Erfindung bezieht sich auf eine Antriebsmaschine für eine Aufzugsanlage und ein Verfahren zur Montage einer Antriebsmaschine gemäss der Definition der Patentansprüche.The present invention relates to a drive machine for an elevator installation and a method for assembling a drive machine according to the definition of the claims.

Die Schrift WO99/43593 zeigt eine Antriebsmaschine mit zwei Treibscheiben für Riemen. Die Treibscheiben sind in den äusseren Bereichen der Kabinenabmessung, zumindest in dem jeweils äusseren Drittel der, der Ausrichtung der Antriebsachse entsprechenden, Kabinenabmessung, oder ausserhalb der Kabine angeordnet. Die Treibscheiben sind beidseitig am Ende der Antriebsmaschine angeordnet.
Die gezeigte Ausführung weist verschiedene Nachteile auf:

  • Raumbedarf: Die Antriebsmaschine belegt einen grossen Raum.
  • Kräfteeinleitung: Die Auflagerkräfte müssen über massive Unterkonstruktionen in die Tragstruktur des Aufzuges eingeleitet werden.
  • Montagehandhabung: Die Montage und im besonderen die Ausrichtung der Treibscheibenachse zur Laufrichtung der Trag- und Treibmittel ist aufwändig.
The document WO99 / 43593 shows a drive machine with two traction sheaves for belts. The traction sheaves are arranged in the outer regions of the cabin dimension, at least in the respective outer third of the cabin dimension corresponding to the orientation of the drive axis, or outside the cabin. The traction sheaves are arranged on both sides at the end of the drive machine.
The embodiment shown has several disadvantages:
  • Space requirement: The drive machine occupies a large space.
  • Force introduction: The support forces must be introduced into the supporting structure of the lift via massive substructures.
  • Assembly handling: The assembly and in particular the alignment of the traction sheave axis to the running direction of the carrying and blowing agent is complex.

Eine Aufgabe der vorliegenden Erfindung ist es, eine Antriebsmaschine und ein Verfahren zur Montage derselben bereitzustellen, welche den Kraftfluss optimiert und damit die Anforderungen an die Anschlusskonstruktion gering hält sowie den Raumbedarf für die Antriebsmaschine minimiert. Die Antriebsmaschine soll zudem eine flexible Anordnung im Schacht erlauben. Der Trag- und Treibmittelstrang soll auf zwei Stränge aufgeteilt sein.An object of the present invention is to provide a prime mover and a method for assembling the same, which optimizes the power flow and thus minimizes the requirements on the adjacent construction and minimizes the space required for the prime mover. The prime mover should also allow a flexible arrangement in the shaft. The carrier and propellant strand is to be divided into two strands.

Diese Aufgabe wird durch die Erfindung gemäss der Definition der unabhängigen Patentansprüche gelöst.This object is achieved by the invention according to the definition of the independent patent claims.

Die Erfindung betrifft eine Antriebsmaschine für eine Aufzugsanlage mit Kabine und Gegengewicht und einem Schacht. Trag- und Treibmittel verbinden die Kabine mit dem Gegengewicht. Die Trag- und Treibmittel werden im folgenden Treibmittel genannt. Die Treibmittel sind über die Antriebsmaschine geführt. Die Treibmittel werden in der Antriebsmaschine von einer Antriebswelle getrieben. Die Zonen der Antriebswelle welche die Kraft auf die Treibmittel übertragen werden im folgenden Treibzonen genannt. Die Kabine und das Gegengewicht werden mittels Kabinenführungsschienen, bzw. Gegengewichtsführungsschienen geführt.The invention relates to a drive machine for an elevator system with cabin and counterweight and a shaft. Carrying and blowing agents connect the cabin to the counterweight. The carrying and blowing agents are called blowing agents in the following. The propellants are passed over the drive machine. The propellants are driven in the prime mover by a drive shaft. The zones of the drive shaft which transmit the force to the propellant are referred to below as the propellant zones. The car and the counterweight are guided by means of car guide rails or counterweight guide rails.

Die Antriebswelle weist zwei voneinander beabstandete Treibzonen auf. Die Treibzonen sind der Form des Treibmittels angepasst. Die Anzahl der Treibmittel ist symmetrisch auf die zwei Treibzonen verteilt, wobei jede Treibzone Platz für mindestens ein Treibmittel bietet.The drive shaft has two spaced apart blowing zones. The blowing zones are adapted to the shape of the blowing agent. The number of propellants is distributed symmetrically over the two propellant zones, with each propellant zone providing space for at least one propellant.

Erfindungsgemäss ist mindestens ein Bauteil der Antriebsmaschine , wie beispielsweise der Motor oder die Bremse, links oder rechts der beiden Treibzonen angeordnet. Der Nutzen dieser Anordnung liegt darin, dass die Abmessungen der Antriebsmaschine verringert werden. Der Abstand der beiden Treibzonen kann dadurch zweckentsprechend verkleinert werden um beispielsweise die Treibmittel in möglichst geringer Distanz links und rechts der Führungsschienen anzuordnen. Dadurch wird der Raumbedarf der Antriebsmaschine und der gesamten Antriebsanordnung minimiert. Die kleinen Abmessungen der Antriebsmaschine erlauben eine kompakte Bauform. Die kompakte Bauform erlaubt im weiteren eine optimale Einleitung der Auflagerkräfte in die Tragstruktur was wiederum einfachere Formen der Unterkonstruktionen ermöglicht. Die Montagehandhabung und die Ausrichtung der Antriebsmaschine wird durch die kompakte Bauform, und der deswegen möglichen Vormontage der einzelnen Baugruppen in einer montagefreundlichen Umgebung, stark verbessert.According to the invention, at least one component of the drive machine, such as the engine or the brake, is arranged on the left or right of the two drive zones. The benefit of this arrangement is that the dimensions of the prime mover are reduced. The distance between the two blowing zones can be reduced as appropriate by, for example, to arrange the propellant in the smallest possible distance left and right of the guide rails. As a result, the space requirement of the drive machine and the entire drive arrangement is minimized. The small dimensions of the drive machine allow a compact design. The compact design allows further optimal introduction of the bearing forces in the support structure which in turn allows simpler forms of the substructures. The assembly handling and the alignment of the drive machine is greatly improved by the compact design, and therefore possible pre-assembly of the individual assemblies in a mounting-friendly environment.

Eine Antriebsmaschine 20 weist wie in in den Fig 1a bis 1e und Fig. 2 bis Fig. 4 dargestellt eine Antriebswelle 4 auf, welche mit zwei in einem Abstand D zueinander beabstandeten Treibzonen 3, 3' versehen ist. Ein Motor 1 und eine Bremse 2 wirken auf die Antriebswelle 4. Die Treibzonen 3, 3' treiben Treibmittel 19, 19' , welche wie beispielhaft in den Fig. 5 bis 8 dargestellt eine Kabine 11 und ein Gegengewicht 12 treiben. Der Abstand D wird vorteilhafterweise so klein wie möglich gewählt. Er ergibt sich beispielsweise aus der beabsichtigten Anordnung der Treibzonen bzw. der Treibmittel 19, 19' beidseitig der Kabinenführungsschiene 5. Der Motor 1 und/oder die Bremse 2 und/oder andere Bauteile wie Drehzahlsensoren, Evakuationshilfen oder optische Anzeiger sind gemäss der Erfindung links und/oder rechts der beiden Treibzonen 3, 3' angeordnet. Unter Ausnutzung der Anordnungsmöglichkeiten der Bauteile der Antriebsmaschine 20 kann die beste Kombination ermittelt werden. Der Nutzen dieser Anordnung ergibt sich daraus, dass der Raumbedarf für die Antriebsmaschine 20 entsprechend der Erfordernis der Anlagenanordnung minimiert werden kann. Die Antriebsmaschine 20 ist mit einer geringen Gesamtlänge ausgeführt. Dies ermöglicht eine weitgehende Vormontage der Antriebsmaschine in einer geeigneten Arbeitsumgebung. Dadurch wird die Montage vereinfacht und Fehlerquellen werden ausgeschaltet.As shown in FIGS. 1a to 1e and FIGS. 2 to 4 , a drive machine 20 has a drive shaft 4, which is connected to one another by two at a distance D. spaced blowing zones 3, 3 'is provided. A motor 1 and a brake 2 act on the drive shaft 4. The drive zones 3, 3 'drive propellant 19, 19', which as shown by way of example in FIGS. 5 to 8 drive a car 11 and a counterweight 12. The distance D is advantageously chosen as small as possible. It results, for example, from the intended arrangement of the blowing zones or the blowing means 19, 19 'on both sides of the car guide rail 5. The engine 1 and / or the brake 2 and / or other components such as speed sensors, evacuation aids or visual indicators are according to the invention left and / or right of the two blowing zones 3, 3 'arranged. By taking advantage of the possible arrangements of the components of the drive machine 20, the best combination can be determined. The benefit of this arrangement results from the fact that the space requirement for the drive machine 20 can be minimized according to the requirement of the system arrangement. The engine 20 is designed with a small overall length. This allows an extensive pre-assembly of the prime mover in a suitable working environment. This simplifies assembly and eliminates sources of error.

Fig 1a zeigt die Anordnung des Motor 1 und eines ersten Lager 28 auf der einen Seite der Treibzonen 3, 3' und der Bremse 2 und eines zweiten Lager 28' auf der anderen Seite der Treibzonen 3, 3'. Konsolen 29, 29'sind entsprechend der Anordnung der Lager 28, 28' auf die Tragstruktur der Aufzugsanlage befestigt. Diese Variante wird vorteilhaft verwendet wenn der Abstand D zwischen den Treibzonen 3, 3' klein gewählt wird, was beispielsweise bei sehr kleinen Führungsschienendimensionen sinnvoll ist. 1a shows the arrangement of the motor 1 and a first bearing 28 on one side of the blowing zones 3, 3 'and the brake 2 and a second bearing 28' on the other side of the blowing zones 3, 3 '. Consoles 29, 29 'are mounted according to the arrangement of the bearings 28, 28' on the support structure of the elevator installation. This variant is advantageously used when the distance D between the blowing zones 3, 3 'is selected to be small, which is useful, for example, in the case of very small guide rail dimensions.

Fig. 1b zeigt in Abweichung zur Fig. 1a die Verwendung einer Zentralkonsole 22 welche die Auflagerkräfte der Antriebsmaschine 20 zentral, im wesentlichen an einer Stelle in die Tragstruktur der Aufzugsanlage führt. Die Zentralkonsole 22 ist rechtwinkelig zur Achse der Antriebsmaschine 20, in einer Symmetrieebene S der zwei Treibzonen 3, 3' wirkend, angeordnet. Dies ermöglicht eine besonders kostengünstige Ausführung der Anschlusskonstruktion. Zudem ermöglicht diese Anordnung die Verwendung einer Niveaueinstellung 27. Die Niveaueinstellung 27 hat dabei nur geringe Differenzkräfte zu übernehmen, die sich im wesentlichen aus den Gewichtskräften des Antriebs selbst, und aus Ungenauigkeiten der Treibmittelanordnung ergeben. Die Niveaueinstellung 27 ermöglicht ohne besonderen Aufwand die Ausrichtung der Achse der Antriebswelle 4 auf die Laufrichtung der Treibmittel 19, 19'. Diese Ausrichtung ist, im besonderen, bei der Verwendung von Riemen als Treibmittel vorteilhaft, da dadurch das Verschleiss- und Geräuschverhalten massgeblich beeinflusst wird. Bei ungenauer Ausrichtung der Antriebsmaschine erhöht sich der Verschleiss der Treibmittel stark, was zu einem frühen Ersatz der Treibmittel und dementsprechend zu hohen Kosten führt.
Beispielhaft ist in dieser Fig. 1b die Bremse 2 und der Motor 1 auf einer Seite der Treibzonen 3, 3' angeordnet. Diese Anordnung ist vorteilhaft wenn der Raum auf der Gegenseite der Treibzonen anderweitig belegt ist. In contrast to FIG. 1 a, FIG. 1 b shows the use of a central console 22 which guides the bearing forces of the drive machine 20 centrally, essentially at one point into the supporting structure of the elevator installation. The central console 22 is perpendicular to the axis of the drive machine 20, in a plane of symmetry S of the two blowing zones 3, 3 'acting arranged. This allows a particularly cost-effective design of the adjacent construction. In addition, this arrangement allows the use of a level adjustment 27. The level adjustment 27 has to take on only small differential forces, resulting essentially from the weight forces of the drive itself, and inaccuracies of the propellant arrangement. The level adjustment 27 allows the alignment of the axis of the drive shaft 4 without any special effort the direction of the propellant 19, 19 '. This orientation is, in particular, advantageous in the use of belts as propellants, as this significantly influences the wear and noise behavior. With inaccurate alignment of the prime mover, the wear of the propellant increases greatly, which leads to an early replacement of the propellant and consequently to high costs.
By way of example, in this Fig. 1b, the brake 2 and the motor 1 on one side of the blowing zones 3, 3 'are arranged. This arrangement is advantageous if the space on the opposite side of the blowing zones is otherwise occupied.

Fig. 1c zeigt die Anordnung eines Zentrallagers 21, welches die, durch die in den Treibmittel 19, 19' vorhandenen Zugkräfte erzeugte, Radialkraft der Antriebswelle 4 an einer zentralen Stelle aufnimmt. Das Zentrallager 21 ist rechtwinkelig zur Achse der Antriebsmaschine, in einer Symmetrieebene S der zwei Treibzonen 3, 3' wirkend angeordnet. Am motorseitigen Ende der Antriebswelle 4 ist ein Stützlager 24 angeordnet. Es übernimmt die im Antriebssystem entstehenden Differenzkräfte. Die Differenzkräfte ergeben sich im wesentlichen aus den Gewichtskräften des Antriebs selbst, und aus Ungenauigkeiten der Treibmittelanordnungen. Das Stützlager 24 gewährleistet zudem eine exakte Einhaltung des Luftspaltes zwischen dem Stator und dem Rotor des Motor 1. Die Antriebsmaschine 20 ist mittels zweier Konsolen 29, 29' auf die Tragstruktur der Aufzugsanlage befestigt. Diese Anordnung ist besonders vorteilhaft, wenn der Abstand D zwischen den Treibzonen 3, 3' genügend Platz für die Anordnung des Zentrallagers 21 lässt und die Anforderungen an die Ausrichtgenauigkeit der Antriebswelle gering sind. Fig. 1c shows the arrangement of a central bearing 21, which receives, by the existing in the propellant 19, 19 'tensile forces generated radial force of the drive shaft 4 at a central location. The central warehouse 21 is perpendicular to the axis of the prime mover, in a plane of symmetry S of the two blowing zones 3, 3 'acting arranged. At the motor end of the drive shaft 4, a support bearing 24 is arranged. It takes over the differential forces arising in the drive system. The differential forces arise essentially from the weight forces of the drive itself, and inaccuracies of the propellant arrangements. The support bearing 24 also ensures exact compliance with the air gap between the stator and the rotor of the engine 1. The drive machine 20 is secured by means of two brackets 29, 29 'on the support structure of the elevator system. This arrangement is particularly advantageous when the distance D between the blowing zones 3, 3 'leaves enough space for the arrangement of the central bearing 21 and the requirements for the alignment accuracy of the drive shaft are low.

Fig. 1d zeigt die Anordnung eines Zentrallagers 21 und einer Zentralkonsole 22, welche die Auflagerkräfte der Antriebsmaschine 20 zentral, im wesentlichen an einer Stelle, in die Tragstruktur der Aufzugsanlage führt. Die Zentralkonsole 22 und das Zentrallager 12 sind rechtwinkelig zur Achse der Antriebsmaschine 20, in einer Symmetrieebene S der zwei Treibzonen 3, 3' wirkend, angeordnet. Eine Niveaueinstellung 27 ist vorzugsweise am motorseitigen Ende der Antriebsmaschine angeordnet. Ein Stützlager 24 ist wie in Fig. 1c gezeigt angeordnet. Die Anordnung der Antriebsmaschine 20 entsprechend der Fig. 1d ist besonders vorteilhaft, da sich kleine Abmessungen der Antriebsmaschine 20 ergeben, die Kräfte in optimaler Weise in die Tragstruktur der Aufzugsanlage eingeleitet werden, die Verwendung von nur zwei Lagerstellen in der Antriebsmaschine 20 eine sichere Auslegung der Antriebswelle 4 ermöglicht und die Ausrichtung der Achse der Antriebswelle 4 zu der Laufrichtung der Treibmittel 19, 19' einfach ausführbar ist. Fig. 1d shows the arrangement of a central warehouse 21 and a central console 22, which leads the support forces of the drive machine 20 centrally, essentially at one point, in the support structure of the elevator installation. The central console 22 and the central warehouse 12 are perpendicular to the axis of the drive machine 20, in a plane of symmetry S of the two blowing zones 3, 3 'acting arranged. A level adjustment 27 is preferably arranged at the engine-side end of the engine. A support bearing 24 is arranged as shown in Fig. 1c . The arrangement of the drive machine 20 according to FIG. 1d is particularly advantageous, since small dimensions of the drive machine 20 result, the forces are optimally introduced into the support structure of the elevator installation, the use of only two bearing points in the drive machine 20 a safe Design of the drive shaft 4 allows and the orientation of the axis of the drive shaft 4 to the direction of the propellant 19, 19 'is easily executable.

Fig. 1e zeigt eine andere Anordnungsmöglichkeit einer Niveaueinstellung 27. Die Niveaueinstellung 27 ist in dieser Ausführungsform direkt am Lagergehäuse angeordnet. Sie ist in ihrer Wirkung identisch zu der unter Fig. 1b, 1d gezeigten Ausführungsform. Der Fachmann kann weitere Ausführungsformen definieren, wie sie für einen spezifischen Anwendungsfall am besten geeignet sind. Fig. 1e shows another possible arrangement of a level adjustment 27. The level adjustment 27 is arranged directly on the bearing housing in this embodiment. It is identical in its effect to the embodiment shown under Fig. 1b, 1d . The person skilled in the art can define further embodiments which are best suited for a specific application.

Die in den Fig. 1a bis 1e gezeigten Anordnungen können vom Fachmann in geeigneter Form kombiniert werden. Die Bremse 2 kann beispielsweise zwischen den Treibzonen 3, 3'angeordnet sein.The arrangements shown in FIGS. 1a to 1e can be combined in a suitable form by the person skilled in the art. The brake 2 can be arranged, for example, between the blowing zones 3, 3 '.

Fig. 2 und Fig. 3 zeigen eine beispielhafte Detailausführung der in Fig 1d dargestellten Anordnung. Die gezeigte Antriebsmaschine 20 weist eine Antriebswelle 4 mit zwei beabstandeten Treibzonen 3, 3' auf. In diesem Beispiel beträgt der Abstand D der beiden Treibzonen 100 bis 250 mm. Dies erlaubt die Anordnung von heute üblichen Führungsschienenprofilen, welche eine Schienfussbreite von 50 bis 140 mm aufweisen. Die Antriebswelle 4 ist in einem Lagergehäuse 7 gelagert. Eine Zentralkonsole 22 ist hierbei in das Lagergehäuse 7 integriert. Die Zentralkonsole 22 ist in einer, rechtwinkelig zur Antriebsachse und in einer durch die beiden Treibzonen definierten, Symmetrieebene S zwischen den beiden Treibzonen 3, 3' angeordnet. Die Antriebswelle 4 ist im Lagergehäuse 7 mittels einem zwischen den Treibzonen 3, 3' angeordneten Zentrallager 21 gelagert. Das Zentrallager 21 ist ebenfalls in der Symmetrieebene S wirkend angeordnet. Das Zentrallager 21 nimmt die von Treibmitteln 19, 19' herrührenden Auflagerkräfte auf und leitet sie über das Lagergehäuse 7, die Zentralkonsole 22 und über ein Zwischenstück in die Tragstruktur der Aufzugsanlage. Die Treibzonen 3,3' sind direkt in die Antriebswelle 4 eingearbeitet. Alternativ können die Treibzonen 3, 3' auch mittels separater Elemente, wie beispielsweise in der Form von Scheiben, auf die Antriebswelle 4 aufgebracht werden. Die Antriebswelle 4, bzw. die Treibzonen 3, 3', ist mit einem Motor 1 und einer Bremse 2 kräftewirksam, vorzugsweise einstückig und getriebelos, verbunden, und ermöglicht damit das Antreiben der Treibmittel 19, 19' mittels der Treibzonen 3, 3'. Die Treibzonen 3, 3'sind in der gezeigten Ausführung ebenfalls einstückig in die Antriebswelle 4 integriert. Dies ist vorteilhaft bei der Verwendung von Riemen als Treibmittel, da diese Treibmittel kleine Umlenk, bzw. Treibradien ermöglichen. Durch die Anordnung des Zentrallagers 21 zwischen den Treibzonen 3, 3' wird der dort zur Verfügung stehende Bauraum effizient genutzt und die äusseren Abmessungen werden reduziert. Durch die Reduktion der Anzahl Lagerstellen werden die Kosten reduziert. Die Qualität der Antriebsmaschine 20 wird durch diese Anordnung wesentlich gesteigert, da durch die Reduktion der Lagerstellen eine Überbestimmung der Wellenlagerung entfällt. Fig. 2 and Fig. 3 show an exemplary detail of the arrangement shown in Figure 1d. The drive machine 20 shown has a drive shaft 4 with two spaced drive zones 3, 3 '. In this example, the distance D of the two blowing zones is 100 to 250 mm. This allows the arrangement of today usual guide rail profiles, which have a rail foot width of 50 to 140 mm. The drive shaft 4 is mounted in a bearing housing 7. A central console 22 is integrated in the bearing housing 7. The central console 22 is arranged in a, perpendicular to the drive axis and in a defined by the two drive zones, symmetry plane S between the two drive zones 3, 3 '. The drive shaft 4 is mounted in the bearing housing 7 by means of a between the drive zones 3, 3 'arranged central warehouse 21. The central warehouse 21 is also arranged acting in the plane of symmetry S. The central warehouse 21 receives the propelling means 19, 19 'resulting bearing forces and directs them via the bearing housing 7, the central console 22 and an intermediate piece in the support structure of the elevator system. The blowing zones 3,3 'are incorporated directly into the drive shaft 4. Alternatively, the blowing zones 3, 3 'can also be applied to the drive shaft 4 by means of separate elements, for example in the form of disks. The drive shaft 4, or the drive zones 3, 3 ', is connected to a motor 1 and a brake 2 forces, preferably in one piece and gearless, connected, and thus allows the driving of the blowing agent 19, 19' by means of the blowing zones 3, 3 '. The blowing zones 3, 3 'are in the embodiment shown also in one piece in the Drive shaft 4 integrated. This is advantageous in the use of belts as blowing agents, since these blowing agents allow small deflection or driving radii. The arrangement of the central warehouse 21 between the blowing zones 3, 3 ', the space available there is used efficiently and the external dimensions are reduced. Reducing the number of bearings reduces costs. The quality of the drive machine 20 is substantially increased by this arrangement, as overdefung the shaft bearing deleted by the reduction of the bearings.

Vorteilhafterweise sind die Bremse 2 und der Motor 1 wie in den Beispielen gezeigt links und rechts der beiden Treibzonen 3, 3'angeordnet. Der Motor 1 und die Bremse 2 sind über das Lagergehäuse 7 kräftewirksam verbunden. Die vom Motor 1 erzeugten Antriebsmomente, und/oder die von der Bremse 2 erzeugten Bremsmomente, werden in das Lagergehäuse 7 und über die Zentralkonsole 22 in die Tragstruktur der Aufzugsanlage eingeleitet. Die gezeigte Anordnung der Treibzonen 3, 3' zwischen der Bremse 2 und dem Motor 1 ermöglicht, zusammen mit der kraftwirksamen Verbindung von Bremse 2, Motor 1 und Lagergehäuse 7 eine besonders platzsparende Ausführung. Zudem ist die Zugänglichkeit zu der Bremse 2 und dem Motor 1 in idealer Weise gewährleistet.Advantageously, the brake 2 and the motor 1 as shown in the examples, left and right of the two blowing zones 3, 3 'arranged. The motor 1 and the brake 2 are force-connected via the bearing housing 7. The drive torques generated by the engine 1, and / or the braking torques generated by the brake 2, are introduced into the bearing housing 7 and via the central console 22 in the support structure of the elevator system. The arrangement shown of the blowing zones 3, 3 'between the brake 2 and the motor 1, together with the force-effective connection of brake 2, motor 1 and bearing housing 7 allows a particularly space-saving design. In addition, the accessibility to the brake 2 and the motor 1 is ensured in an ideal manner.

Am motorseitigen Ende der Antriebswelle 4 ist ein Stützlager 24 angeordnet. Das Stützlager 24 übernimmt die im Antriebssystem entstehenden Differenzkräfte. Die Differenzkräfte ergeben sich im wesentlichen aus den Gewichtskräften des Antriebs selbst, und aus Ungenauigkeiten der Treibmittelanordnungen. Das Stützlager 24 gewährleistet zudem eine exakte Einhaltung des Luftspaltes zwischen dem Stator und dem Rotor des Motors 1. Das Stützlager 24 leitete die Differenzkräfte in das Gehäuse des Motors und das Lagergehäuse 7. Die resultierenden Stützkräfte werden von einer Niveaueinstellung 27 aufgenommen und in die Tragstruktur der Aufzugsanlage eingeleitet. Die Niveaueinstellung 27 dient gleichzeitig dem genauen und einfachen Ausnivellieren der Achse der Antriebswelle 4 zu den Treibmitteln 19, 19'. Diese Ausrichtung ist im besonderen bei der Verwendung von Riemen als Treibmittel vorteilhaft, da dadurch das Verschleiss- und Geräuschverhalten massgeblich beeinflusst wird.At the motor end of the drive shaft 4, a support bearing 24 is arranged. The support bearing 24 takes over the differential forces arising in the drive system. The differential forces arise essentially from the weight forces of the drive itself, and inaccuracies of the propellant arrangements. The support bearing 24 also ensures accurate compliance with the air gap between the stator and the rotor of the motor 1. The support bearing 24 directed the differential forces in the housing of the motor and the bearing housing 7. The resulting support forces are absorbed by a level adjustment 27 and in the support structure of Lift system initiated. The level adjustment 27 serves at the same time for precise and simple leveling out of the axis of the drive shaft 4 to the propellant means 19, 19 '. This orientation is particularly advantageous in the use of belt as a propellant, as this significantly affects the wear and noise behavior.

Alternativ kann wie in Fig 1e gezeigt die Niveaueinstellung 27 beispielsweise horizontal angeordnet werden.Alternatively, as shown in Fig. 1e , the level setting 27 may be arranged horizontally, for example.

Das in den Fig. 2 und 3 dargestellte Lagergehäuse 7 umschliesst die Antriebswelle 4 mit den Treibzonen 3, 3'teilweise. Dies bildet einen direkten Schutz der Treibzonen 3, 3' vor unbeabsichtigter Berührung und Einklemmgefahr von Montage- oder Servicepersonal, verhindert aber auch die Beschädigung der Treibzone oder der Treibmittel durch herunterfallende Gegenstände. Zugleich gewinnt das Lagergehäuse dadurch die erforderliche Festigkeit um die Kräfte und Momente aus dem Motor 1 und der Bremse 2 zu übernehmen.The bearing housing 7 shown in Figs. 2 and 3 encloses the drive shaft 4 with the blowing zones 3, 3 'partially. This forms a direct protection of the blowing zones 3, 3 'from accidental contact and risk of entrapment by assembly or service personnel, but also prevents the damage of the blowing zone or the propellant by falling objects. At the same time, the bearing housing thereby gains the required strength to take over the forces and moments from the engine 1 and the brake 2.

Die Antriebsmaschine 20 ist mittels Schwingungsisolationen 23, 26 befestigt. Dies ermöglicht eine weitgehende Schwingungsentkoppelung der Antriebsmaschine 20 von der Tragstruktur der Aufzugsanlage. Die Geräusche in der Aufzugsanlage und/oder im Gebäude werden dadurch reduziert.The engine 20 is secured by means of vibration isolations 23, 26. This allows a substantial decoupling of vibration of the drive machine 20 of the support structure of the elevator system. The noise in the elevator system and / or in the building are thereby reduced.

Zur einfachen Gestaltung der Zentrallagerung ist in der gezeigten Ausführung der Innendurchmesser des Zentrallagers 21 grösser als der Durchmesser der Treibzone 3, 3' gewählt.For easy design of the central storage of the inner diameter of the central warehouse 21 is greater than the diameter of the blowing zone 3, 3 'selected in the embodiment shown.

Durch die gezeigte Konstruktionsform wird eine kosten- und raumoptimale Antriebsform angeboten. Im besonderen kann die Montage und Ausrichtung der Antriebsmaschine einfach und schnell erfolgen. Die Auslegung der Antriebkomponenten ist vereinfacht, da die Belastung der Antriebswelle 4 und des Lagergehäuses 7 durch die erreichte 2-Punktlagerung ideal definiert ist.The design shown a cost and space optimal drive form is offered. In particular, the assembly and alignment of the drive machine can be done easily and quickly. The design of the drive components is simplified because the load on the drive shaft 4 and the bearing housing 7 is ideally defined by the achieved 2-point bearing.

Fig. 2 zeigt eine perspektivische Ansicht eines Ausführungsbeispiels einer Anordnung einer getriebelosen Antriebsmaschine 20. Die Antriebsmaschine 20 ist auf einer weitgehend horizontal im Schacht 10 angeordneten Traverse 8 montiert. Die Traverse 8 ist bspw. ein länglicher Vierkant aus bewährten Materialien wie Stahl. In diesem ersten Ausführungsbeispiel ist die Traverse 8 an Gegengewichtsführungen 9, 9' und an einer Kabinenführung 5 der ersten Wand befestigt. Vorteilhafterweise ist die Traverse über zwei Endbereiche an den Gegengewichtsführungen 9, 9' und über einen mittleren Bereich an einer Kabinenführung befestigt. Die Befestigung der Traverse 8 an diesen drei Führungen erfolgt in den drei Befestigungsbereichen bspw. über Schraubverbindungen. Die gezeigte Ausführungsform ergibt eine in optimale Ausnutzung des Bauraumes und ermöglicht die kostenoptimale weitgehende Vorbereitung der Montageeinheit im Fabrikationswerk oder einer entsprechenden Umgebung. 2 shows a perspective view of an exemplary embodiment of an arrangement of a gearless drive machine 20. The drive machine 20 is mounted on a traverse 8 which is arranged substantially horizontally in the shaft 10. The traverse 8 is, for example, an elongated square of proven materials such as steel. In this first embodiment, the cross member 8 is attached to counterweight guides 9, 9 'and to a cabin guide 5 of the first wall. Advantageously, the traverse is attached to the counterweight guides 9, 9 'via two end regions and to a cabin guide via a central region. The attachment of the cross member 8 to these three guides takes place in the three attachment areas eg. Via screw. The embodiment shown results in an optimal utilization of the space and allows the Cost-effective extensive preparation of the assembly unit in the factory or a corresponding environment.

Eine Steuerung und/oder ein Umformer 6 der Aufzugsanlage ist wie der Fig. 2 gezeigt in der Nähe der Antriebsmaschine, vorteilhafterweise ebenfalls auf der Traverse 8 befestigt. Diese Befestigung ist, falls erforderlich, schwingungsisoliert. Die Antriebsmaschine kann somit zusammen mit dem zugehörigen Umrichter mit vorgefertigten Verkabelungen geliefert und montiert werden. Allfällige Lageänderungen, die sich durch Baukontraktion ergeben können haben keine Auswirkung und die gesamte Einheit kann besonders kostengünstig bereitgestellt werden. Falls sinnvoll kann die Steuerung und/oder Umrichter zusätzlich zur Wand abgestützt werden.A control and / or a converter 6 of the elevator installation is, as shown in FIG. 2 , fastened in the vicinity of the drive machine, advantageously also on the cross member 8. This attachment is, if necessary, vibration isolated. The prime mover can thus be delivered and assembled together with the associated inverter with prefabricated cabling. Any positional changes that may result from construction contraction have no effect and the entire unit can be provided at particularly low cost. If appropriate, the controller and / or inverter can be supported in addition to the wall.

An der Antriebsmaschine 20 ist vorteilhafterweise, wie in Fig. 3 gezeigt, eine Nivellierwaage 25 angeordnet. Die Nivellierwaage 25 ist beispielsweise als Wasserwaage ausgeführt, welche die horizontale Lage der Antriebsmaschine 20 anzeigt. Die Nivellierwaage 25 erlaubt eine einfache Kontrolle der ordnungsgemässen Ausnivellierung und ermöglicht dementsprechend eine schnelle Korrektur der Ausrichtung der Antriebsmaschine 20.On the drive machine 20 is advantageously, as shown in Fig. 3 , a leveling scale 25 is arranged. The leveling scale 25 is designed for example as a spirit level, which indicates the horizontal position of the drive machine 20. The leveling scale 25 allows easy control of the proper leveling and accordingly allows a rapid correction of the orientation of the engine 20.

Die Anwendung der beispielhaft gezeigten Antriebsmaschine 20 ist universell für viele Anlagentypen möglich. Die in der Fig. 2 gezeigte Anordnung nimmt Bezug auf einen Aufzug ohne separaten Maschinenraum. Die Anwendung ist jedoch nicht auf maschinenraumlose Aufzugsanlagen begrenzt. Bei vorhandenem Maschinenraum lässt sich beispielsweise der Antrieb, wie in Fig. 6 gezeigt, ebenfalls auf der Schachtdecke anbringen.The application of the prime mover 20 shown by way of example is universally possible for many plant types. The arrangement shown in FIG. 2 refers to an elevator without a separate machine room. However, the application is not limited to machine room-less elevator systems. If there is an engine room, for example, the drive, as shown in Fig. 6 , also attach to the shaft ceiling.

Mit den gezeigten Möglichkeiten lässt sich die Anordnung der Antriebsmaschine beispielsweise bei Modernisierungen an vorgegebene Schachtverhältnisse flexibel anpassen, welche Flexibilität somit die Verwendung von Standardteilen ermöglicht und kostenträchtige Sonderlösungen vermeidet.With the options shown, the arrangement of the prime mover can be flexibly adapted to given shaft conditions, for example in modernizations, which flexibility thus enables the use of standard parts and avoids costly special solutions.

Im folgenden sind verschiedene Anordnungsmöglichkeiten beispielhaft dargestellt.In the following, various arrangement options are shown by way of example.

Fig. 4 und 5 zeigen eine bevorzugte Anwendung der erfindungsgemässen Antriebsmaschine wie sie beispielsweise bei Neuanlagen verwendet wird. Die Figuren zeigen die Dreiecks-Anordnung von Führungen 5, 5', 9, 9' einer Aufzugsanlage. Die Aufzugsanlage ist bspw. in einem weitgehend vertikalen Schacht 10 angeordnet. Der Schacht 10 weist bspw. einen rechteckigen Querschnitt mit vier Wänden auf. Im Schacht sind weitgehend vertikal angeordnete Kabinenführungen 5, 5' und Gegengewichtsführungen 9, 9' befestigt. Zwei Kabinenführungen führen eine Kabine 11 und zwei Gegengewichtsführungen führen ein Gegengewicht 12. Die Führungen sind an nächstliegenden Wänden befestigt. Die zwei Gegengewichtsführungen 9, 9' und eine erste Kabinenführung 5 sind an einer ersten Wand befestigt. Die zweite Kabinenführung 5' ist an einer zweiten Wand befestigt. Die zweite Wand liegt der ersten Wand gegenüber. Die erste Kabinenführung 5 ist weitgehend mittig zwischen den zwei Gegengewichtsführungen 9, 9' angeordnet. Die Führungen sind aus bewährten Materialien wie Stahl. Die Befestigung der Führungen an den Wänden erfolgt bspw. über Schraubverbindungen. Bei Kenntnis der vorliegenden Erfindung lassen sich auch andere Schachtgeometrien mit quadratischem-, ovalem- bzw. rundem Querschnitt realisieren. 4 and 5 show a preferred application of the inventive drive machine as used for example in new plants. The figures show the triangular arrangement of guides 5, 5 ', 9, 9' of an elevator installation. The elevator installation is, for example, arranged in a largely vertical shaft 10. The shaft 10 has, for example, a rectangular cross section with four walls. In the shaft largely vertically arranged cabin guides 5, 5 'and counterweight guides 9, 9' are attached. Two car guides carry a car 11 and two counterweight guides carry a counterweight 12. The guides are attached to nearest walls. The two counterweight guides 9, 9 'and a first cabin guide 5 are fixed to a first wall. The second cabin guide 5 'is attached to a second wall. The second wall is opposite the first wall. The first cabin guide 5 is arranged substantially centrally between the two counterweight guides 9, 9 '. The guides are made of proven materials such as steel. The attachment of the guides on the walls takes place, for example, via screw. With knowledge of the present invention, other shaft geometries with square, oval or round cross-section can be realized.

Die zwei Gegengewichtsführungen 9, 9' und jeweils eine der beiden Kabinenführungen 5, 5' spannen im Schacht 10 ein weitgehend horizontales Dreieck T auf. Die horizontale Verbindende zwischen den beiden Gegengewichtsführungen bildet eine erste Seite des Dreiecks T. Die horizontalen Verbindenden zwischen einer Gegengewichtsführung und einer Kabinenführung bilden zweite- und dritte Seiten des Dreiecks T. Vorteilhafterweise schneidet die horizontale Verbindende der Kabinenführungen H die horizontale Verbindende der Gegengewichtsführungen weitgehend mittig, so dass das Dreieck T weitgehend gleichschenklig ist.The two counterweight guides 9, 9 'and one of the two cabin guides 5, 5' span in the shaft 10 a largely horizontal triangle T. The horizontal connecting end between the two counterweight guides forms a first side of the triangle T. The horizontal connecting ends between a counterweight guide and a car guide form second and third sides of the triangle T. Advantageously, the horizontal connecting end of the car guides H largely crosses the horizontal connecting end of the counterweight guides. so that the triangle T is largely isosceles.
