Abstract

The escalator has a truss (4) and a shaft (5). A shaft-bearing has two sockets, each arranged on an opposed end of the shaft for holding the shaft in the truss. The shaft-bearing comprises a hub, where hub is tightly fastened to the truss and supports the socket. The shaft is borne by the socket, where the shaft is mounted upon the hub by the socket. The socket is adapted and constructed to be movable along the shaft. An independent claim is also included for a method of supporting a shaft of an escalator by a shaft-bearing in a truss.

Description

Die Erfindung betrifft eine Fahrtreppe bzw. Fahrsteig mit Fachwerk, Welle und Wellenlagerung zum Lagern der Welle im Fachwerk gemäss der Definition der unabhängigen Patentansprüche und ein Verfahren zur Montage bzw. Demontage dieser Fahrtreppe.The invention relates to an escalator or moving walk with truss, shaft and shaft bearing for supporting the shaft in the framework according to the definition of the independent claims and a method for assembling or disassembling this escalator.

In der weiteren Beschreibung soll der Ausdruck Fahrtreppe auch Fahrsteige und der Ausdruck Stufe auch Fahrsteig-Paletten einschliessen.In the further description, the term escalator is also to include moving walks and the expression level also pavement pallets.

Die Stufen einer üblichen Fahrtreppe sind an zwei Transportketten befestigt und bilden zusammen mit diesen ein endloses, umlaufendes Stufenband, das über je ein Paar Transportkettenräder an beiden Enden der Fahrtreppe läuft, wobei das eine Transportkettenradpaar zur Antriebsstation gehört und das Stufenband antreibt und umlenkt und das andere Kettenradpaar Teil einer Stufenband-Umlenkstation ist. Die einzelnen Stufen des Stufenbands sind mit je zwei vorderen und zwei hinteren Führungsrollen ausgerüstet, an denen die Stufen durch vorwiegend an der Tragkonstruktion der Fahrtreppe befestigte Führungsschienen und Kurven bzw. Umlenkbögen in positionsabhängig definierter Lage geführt werden.The steps of a conventional escalator are attached to two transport chains and together with these form an endless, revolving step band, which runs over a pair of transport sprockets at both ends of the escalator, one transport sprocket pair belonging to the drive station and driving and deflecting the step belt and the other Sprocket pair is part of a step-band diverter station. The individual stages of the step belt are equipped with two front and two rear guide rollers, on which the steps are guided by guide rails and curves or deflection arches, which are fastened predominantly to the supporting structure of the escalator, in a position-dependent defined position.

Bei einer Fahrtreppe bzw. einem Fahrsteig mit Balustrade wird am oberen Treppenkopf eine Hauptwelle eingebaut. Die Hauptwelle wird links und rechts im Fachwerk gelagert. Diese Lagerung ist so einfach wie möglich auszuführen, da bei einem Lagerschaden eine Demontage der Hauptwelle erfolgen muss.In an escalator or a moving walk with balustrade a main shaft is installed at the top of the staircase. The main shaft is stored left and right in the truss. This storage is to be carried out as simply as possible, since a bearing damage disassembly of the main shaft must be done.

Die Hauptwelle treibt die Stufen bzw. Paletten an, welche auf Laufbahnschienen geführt werden. Um das Antreiben der Stufen bzw. Paletten leichter zu machen, ist z.B. die Hauptwelle als Hohlwellenkonstruktion ausgeführt. Nach dieser Hohlwellenkonstruktion besteht die Hauptwelle aus einer feststehenden Achse, die im Fachwerk der Fahrtreppe gelagert wird. Um diese Achse wird eine drehende Hohlwelle angebracht, welche durch Wälzlager mit der Achse in Verbindung steht. Diese Hohlwelle dreht und trägt das Stufenband bzw. das Palettenband. Die Achse, die die Hohlwelle trägt, ist typischerweise fest am Fachwerk verschraubt.The main shaft drives the steps or pallets, which are guided on track rails. To make the driving of the pallets easier, e.g. the main shaft designed as a hollow shaft construction. After this hollow shaft construction, the main shaft consists of a fixed axis, which is stored in the truss of the escalator. Around this axis, a rotating hollow shaft is mounted, which is connected by rolling bearings with the axis. This hollow shaft rotates and carries the step band or the pallet band. The axle that carries the hollow shaft is typically bolted to the truss.

Die beschriebene Ausführung weist den Nachteil auf, dass z.B. im Falle eines Wälzlagerdefekts umfangreiche Demontage- und Montagearbeiten erforderlich sind, da sich die Wälzlager nur durch Längsverschieben bis zum Achsende entfernen und wieder aufbringen lassen. Um die Wälzerlager und die Hohlwelle auszuziehen muss die feststehende Achse vom Fachwerk demontiert werden, was aufwendig und zeitraubend ist, vor allem im Betracht des Gewichtes einer solchen Achse (500 Kg). Die Forderung nach kurzen Unterbruchszeiten zur Behebung jeder Art von möglichen Defekten kann mit der bisherigen Konstruktion nicht erfüllt werden.The embodiment described has the disadvantage that e.g. in the case of a rolling bearing defect extensive disassembly and assembly work is required because the bearings can only be removed by longitudinal displacement to the axle end and reapply. To remove the roller bearing and the hollow shaft, the fixed axle must be removed from the truss, which is time-consuming and time-consuming, especially considering the weight of such an axle (500 kg). The requirement for short interruption times to remedy any type of possible defects can not be met with the previous design.

Die Montage der Welle erfolgt bei der Installation der Fahrtreppe. Die Demontage der Welle erfolgt bei der Wartung der Fahrtreppe. Installation und Wartung sind zwei verschiedene Stufen der Wertschöpfungskette.The shaft is mounted during the installation of the escalator. Disassembly of the shaft takes place during maintenance of the escalator. Installation and maintenance are two different stages of the value chain.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei einer Fahrtreppe bzw. einem Fahrsteig den genannten Nachteil zu vermeiden, d. h., den Austausch eines defekten Wälzlagers oder jeder beliebigen Komponente in wesentlich reduzierter Zeit zu ermöglichen. Der vorliegenden Erfindung liegt auch die Aufgabe zugrunde, bei einer Fahrtreppe bzw. einem Fahrsteig eine einfachere und schnellere Montage und Demontage der Welle zu ermöglichen, wobei auch möglichst wenige Bauteile zum Einsatz kommen, was zu einer Reduktion der Montagekosten führt.The present invention has for its object to avoid at an escalator or a moving walkway said disadvantage, ie, the replacement of a defective rolling bearing or any component in a much reduced time enable. The present invention is also based on the object to allow for an escalator or a moving walk a simpler and faster assembly and disassembly of the shaft, with as few components are used, resulting in a reduction of assembly costs.

Die Aufgabe der Erfindung wird durch die in den unabhängigen Ansprüchen angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.The object of the invention is achieved by the features specified in the independent claims. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Wie in Anspruch 1 beansprucht, besteht die Fahrtreppe bzw. Fahrsteig aus einem Fachwerk, einer Welle und mindestens einer Wellenlagerung zum Lagern der Welle im Fachwerk, wobei die Wellenlagerung aus einer Ankerscheibe und einer Topfscheibe besteht, die Ankerscheibe fest mit dem Fachwerk verbunden ist, und die Topfscheibe die Welle auf der Ankerscheibe hält.As claimed in claim 1, the escalator or moving walk consists of a framework, a shaft and at least one shaft bearing for supporting the shaft in the framework, wherein the shaft bearing consists of an armature disc and a cup wheel, the armature disc is firmly connected to the framework, and the cup wheel holds the shaft on the anchor plate.

Da die Topfscheibe die Welle auf der Ankerscheibe hält, kann die Welle schnell und einfach demontiert werden, indem die Topfscheibe entfernt wird, d.h. längs der Welle geschoben wird. Ein schneller und einfacher Montagevorgang wird durch die entgegengesetzte Operation bzw. Durchführung bewirkt.Since the cup wheel holds the shaft on the armature disk, the shaft can be disassembled quickly and easily by removing the cup wheel, i. is pushed along the shaft. A quick and easy assembly operation is effected by the opposite operation.

Durch den unkomplizierten, einfachen Montage- und Demontagevorgang kann wertvolle Arbeitszeit gespart werden. Auf Grund der wenigen Teile und der einfachen Teilefertigung ist diese Wellenlagerung sehr ökonomisch. Dementsprechend ist die neue Wellenlagerung einfacher, leichter, billiger und unkomplizierter. Schnelleres und leichteres Montieren und Demontieren und die wenigen Teile sind ein zusätzlicher Vorteil der neuen Wellenlagerung.The uncomplicated, simple assembly and disassembly process can save valuable working time. Due to the few parts and the simple parts production, this shaft bearing is very economical. Accordingly, the new shaft bearing is simpler, lighter, cheaper and less complicated. Faster and easier assembly and disassembly and the few parts are an added benefit of the new shaft bearing.

Gemäss einer zweckmässigen Ausgestaltung der erfindungsgemässen Fahrtreppe wird die Topfscheibe endständig an der Welle angebracht. Diese Positionierung der Topfscheibe ermöglicht die optimale Übertragung der Last der Welle auf das Fachwerk der Fahrtreppe.According to an expedient embodiment of the inventive escalator, the cup wheel is attached terminally to the shaft. This positioning of the cup wheel allows optimum transfer of the load of the shaft to the truss of the escalator.

Nach einer noch vorteilhafteren Ausführung der Erfindung wird eine Topfscheibe an jedes Ende der Welle angebracht. Die Last der Welle wird somit ständig auf die linke und rechte Seite des Fachwerks in einer ausgeglichen Masse übertragen.According to an even more advantageous embodiment of the invention, a cup wheel is attached to each end of the shaft. The load of the shaft is thus constantly transmitted to the left and right sides of the truss in a balanced mass.

Eine besonders vorteilhafte Ausführung der Erfindung ergibt sich, wenn die Welle als Hohlwellenkonstruktion ausgeführt wird. Die Hohlwelle kann unter diesen Bedingungen sehr schnell und einfach demontiert werden und von der feststehenden Achse abgezogen werden.A particularly advantageous embodiment of the invention results when the shaft is designed as a hollow shaft construction. The hollow shaft can be dismantled very quickly and easily under these conditions and be deducted from the fixed axis.

Eine andere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass die Ankerscheibe mit dem Fachwerk formschlüssig bzw. kraftschlüssig bzw. stoffschlüssig verbunden ist. Damit wird die maximale Festigkeit der mechanischen Verbindung Ankerscheibe-Fachwerk erreicht.Another advantageous embodiment of the invention is that the armature disk is connected to the truss in a form-fitting or non-positive or cohesive manner. Thus, the maximum strength of the mechanical connection armature pulley truss is achieved.

Nach einer weiteren Ausführung der Erfindung wird die Topfscheibe so konfiguriert, dass sie über die Ankerscheibe gestülpt bzw. aufgesetzt bzw. überzogen werden kann. Dies ermöglicht eine optimierte mechanische Anpassung zwischen Ankerscheibe und Topfscheibe zu erreichen.According to a further embodiment of the invention, the cup wheel is configured so that it can be placed over the armature disk or placed or coated. This makes it possible to achieve an optimized mechanical adaptation between armature disk and cup wheel.

Die Fahrtreppe lässt sich montieren, wie im Verfahren gemäss Patentanspruch 8 beansprucht. Eine Welle einer Fahrtreppe bzw. Fahrsteiges wird über eine Wellenlagerung in einem Fachwerk gelagert, wobei eine Ankerscheibe der Wellenlagerung fest mit dem Fachwerk verbunden wird, eine Topfscheibe der Wellenlagerung auf die Welle gesetzt wird, die Welle in einer definierten Position positioniert wird, die Topfscheibe längs der Welle auf die Ankerscheibe geschoben und mit der Ankerscheibe verbunden wird.The escalator can be mounted as claimed in the method according to claim 8. A shaft of an escalator or moving walk is mounted on a shaft bearing in a truss, with an anchor disc of the shaft bearing firmly the truss is connected, a cup wheel of the shaft bearing is placed on the shaft, the shaft is positioned in a defined position, the cup wheel is pushed along the shaft on the armature disk and connected to the armature disk.

Da die Topfscheibe längs der Welle auf die Ankerscheibe geschoben und mit der Ankerscheibe verbunden wird, kann die Welle durch diese Operation schnell und einfach montiert werden.Since the cup wheel is pushed along the shaft onto the armature disk and connected to the armature disk, the shaft can be mounted quickly and easily by this operation.

Die Fahrtreppe lässt sich demontieren, wie im Verfahren gemäss Patentanspruch 9 beansprucht. Eine über eine Wellenlagerung fest mit einem Fachwerk verbundene Welle einer Fahrtreppe bzw. eines Fahrsteiges wird demontiert, indem eine Topfscheibe der Wellenlagerung von einer Ankerscheibe der Wellenlagerung gelöst wird, und die Topfscheibe längs der Welle von der Ankerscheibe weg geschoben wird.The escalator can be disassembled as claimed in the method according to claim 9. A connected via a shaft bearing fixed to a truss shaft of an escalator or a moving walk is disassembled by a cup wheel of the shaft bearing is released from an anchor disc of the shaft bearing, and the cup wheel is pushed along the shaft of the armature disc away.

Die Welle kann somit schnell und einfach demontiert werden, indem die Topfscheibe längs der Welle von der Ankerscheibe weg geschoben wird.The shaft can thus be dismantled quickly and easily by the cup wheel is pushed along the shaft away from the armature disk.

In Fig. 1 sind die wesentlichsten Komponenten einer Fahrtreppe 1 schematisch dargestellt. In eine Fahrtreppen-Tragkonstruktion ist ein umlaufendes, endloses Stufenband integriert, das von einer Antriebseinheit über eine Transportketten-Antriebsräder-Einheit angetrieben ist.In Fig. 1 the most essential components of an escalator 1 are shown schematically. In an escalator support structure, a revolving, endless step belt is integrated, which is driven by a drive unit via a transport chain drive wheels unit.

In Fig. 1 sieht man insbesondere die Fahrtreppe 1 mit einer Balustrade 2, den Stufen 3 und dem Fachwerk 4. Bei der Fahrtreppe bzw. Fahrsteig 1 mit Balustrade 2 wird am oberen Treppenkopf eine Welle 5 eingebaut. Die Welle 5 wird bei dieser neuen Erfindung simpler gelagert und das Fachwerk 4 kann schlanker ausgeführt werden. Die Welle 5 ist im oberen Teil der Fahrtreppe 1 ersichtlich.In Fig. 1 you can see in particular the escalator 1 with a balustrade 2, the steps 3 and the framework 4. In the escalator or moving walk 1 with balustrade 2, a shaft 5 is installed at the top of the staircase. The shaft 5 is stored simpler in this new invention and the truss 4 can be made leaner. The shaft 5 can be seen in the upper part of the escalator 1.

In Fig. 2 sieht man die Wellenlagerung 7 am oberen Teil(Kopf) der Fahrtreppe 1, sowie die Welle 5 als auch das Fachwerk 4 und die Laufbahnschienen 6. Eine Ankerscheibe 8 ist im oberen Teil der Fahrtreppe 1 ersichtlich.In Fig. 2 you can see the shaft bearing 7 at the top (head) of the escalator 1, and the shaft 5 and the truss 4 and the track rails 6. An anchor plate 8 is visible in the upper part of the escalator 1.

In Fig. 3 sieht man die Welle 5 als Vollschnitt, die Ankerscheibe bzw. Stützscheibe 8 und die Topfscheibe bzw. Glockenscheibe 9, die längs der Welle verschiebbar ist. Die Welle 5 ist als Hohlwellenkonstruktion ausgeführt. Nach dieser Hohlwellenkonstruktion besteht die Welle aus einer feststehenden Achse, die im Fachwerk der Fahrtreppe gelagert wird. Um diese Achse wird eine drehende Hohlwelle angebracht, welche durch Wälzlager mit der Achse in Verbindung steht. Diese Hohlwelle dreht sich und trägt das Stufenband. Die Achse, die die Hohlwelle trägt, muss fest am Fachwerk befestigt werden. In diesem Ausführungsbeispiel ist die Welle 5 die Hauptwelle der Fahrtreppe, d.h. die Welle an welche die Antriebskraft ausgeübt wird.In Fig. 3 you can see the shaft 5 as a full cut, the armature disk or support disk 8 and the cup wheel or bell disk 9, which is displaceable along the shaft. The shaft 5 is designed as a hollow shaft construction. After this hollow shaft construction, the shaft consists of a fixed axis, which is stored in the truss of the escalator. Around this axis, a rotating hollow shaft is mounted, which is connected by rolling bearings with the axis. This hollow shaft rotates and carries the step band. The axle that carries the hollow shaft must be firmly fastened to the truss. In In this embodiment, the shaft 5 is the main shaft of the escalator, that is, the shaft to which the driving force is applied.

In Fig. 4 sieht man die Wellenlagerung 7 als Viertelschnitt, mit der Ankerscheibe bzw. Stützscheibe 8 und der Topfscheibe bzw. Glockenscheibe 9 plus der Welle 5 und dem Fachwerk 4.4 shows the shaft bearing 7 as a quarter section, with the armature disk or support disk 8 and the cup wheel or bell disk 9 plus the shaft 5 and the truss 4th

Nach dem beiliegenden Ausführungsbeispiel der Erfindung weist die Fahrtreppe 1 bzw. Fahrsteig das Fachwerk 4, die Welle 5 und die Wellenlagerung 7 zum Lagern der Welle 5 im Fachwerk 4 auf, wobei die Wellenlagerung 7 aus einer Ankerscheibe 8 und einer Topfscheibe 9 besteht, die Ankerscheibe 8 fest mit dem Fachwerk 4 verbunden ist und die Topfscheibe 9 die Welle 5 auf der Ankerscheibe 8 hält.According to the enclosed embodiment of the invention, the escalator 1 or moving walk the truss 4, the shaft 5 and the shaft bearing 7 for supporting the shaft 5 in the framework 4, wherein the shaft bearing 7 consists of an armature disc 8 and a cup wheel 9, the armature disc 8 is fixedly connected to the truss 4 and the cup wheel 9, the shaft 5 holds on the armature disk 8.

Die neue Wellenlagerung 7 wird durch wenige Teile gebildet. Die Ankerscheibe 8 wird mit dem Fachwerk 4 formschlüssig bzw. kraftschlüssig bzw. stoffschlüssig verbunden (z.B. verschraubt bzw. verstiftet bzw. verschweißt). Diese sehr massive Ankerscheibe 8 übernimmt die Stützfunktion für die bis 500 kg schwere Hauptwelle 5. Über die Ankerscheibe bzw. Stützscheibe 8 wird die Topfscheibe bzw. Glockenscheibe 9 gestülpt bzw. aufgesetzt bzw. übergezogen und hält dadurch die Hauptwelle 5. Die Ankerscheibe 8 ist also mit dem Fachwerk 4 verbunden. Die Topfscheibe 9 liegt auf der Ankerscheibe 8 auf und stützt sich auf der Ankerscheibe 8 ab. Die Hauptwelle 5 wird von der Topfscheibe 9 gehalten bzw. gelagert. Die umschließende Topfscheibe 9 wird - wie schon oben erwähnt - von der Ankerscheibe 8 gehalten.The new shaft bearing 7 is formed by a few parts. The armature disk 8 is connected to the framework 4 in a form-fitting or force-fit manner (for example screwed or pinned or welded together). This very massive armature disc 8 takes over the support function for the up to 500 kg heavy main shaft 5. About the armature disk or support disk 8, the cup wheel or bell plate 9 is slipped or placed or pulled and thereby holds the main shaft 5. The anchor plate 8 is thus connected to the framework 4. The cup wheel 9 rests on the armature disk 8 and is supported on the armature disk 8. The main shaft 5 is held or supported by the cup wheel 9. The surrounding cup wheel 9 is - as mentioned above - held by the armature disc 8.

Die Hauptwelle 5 wird vorzugsweise links und rechts im Fachwerk 4 gelagert. Eine Topfscheibe 9 wird endständig an jedes Ende der Welle angebracht. Diese Lagerung ist so einfach wie möglich auszuführen, da bei einem Lagergebrechen eine Demontage der Hauptwelle 5 erfolgen muss.The main shaft 5 is preferably mounted on the left and right in the truss 4. A cup wheel 9 is terminal at each end of the Shaft attached. This storage is to be carried out as simply as possible, since in case of bearing failure disassembly of the main shaft 5 must be carried out.

Die neue Wellenlagerung 7 verrichtet mehrere Aufgaben gleichzeitig. Sie besteht aus wenigen Teilen und vereinfacht deren Demontage.The new shaft bearing 7 performs several tasks simultaneously. It consists of few parts and simplifies their dismantling.

Die Hauptwelle 5 treibt die Stufen bzw. Paletten 3 an, die auf Laufbahnschienen 6 geführt werden. Um das Antreiben der Stufen bzw. Paletten 3 leichter zu machen, wird die Hauptwelle 5 vorzugsweise als Hohlwellenkonstruktion ausgeführt.The main shaft 5 drives the steps or pallets 3, which are guided on track rails 6. In order to make the driving of the steps or pallets 3 easier, the main shaft 5 is preferably designed as a hollow shaft construction.

Nach dem beiliegenden Ausführungsbeispiel der Erfindung wird die über die Wellenlagerung 7 fest mit dem Fachwerk 4 verbundene Welle 5 der Fahrtreppe bzw. Fahrsteiges demontiert, indem die Topfscheibe 9 der Wellenlagerung 7 von der Ankerscheibe 8 der Wellenlagerung 7 gelöst wird und die Topfscheibe 9 längs der Welle 5 von der Ankerscheibe 8 weg geschoben wird.After the enclosed embodiment of the invention, connected via the shaft bearing 7 fixed to the truss 4 shaft 5 of the escalator or moving walk is dismantled by the cup wheel 9 of the shaft bearing 7 is released from the armature disk 8 of the shaft bearing 7 and the cup wheel 9 along the shaft 5 is pushed away from the armature disk 8.

Die vorliegende Erfindung stellt eine wesentliche Vereinfachung der Wellendemontagemethode dar, denn die Wellenlagerung 7 ist einfacher aufgebaut als früher und wird durch das Prinzip Topf- und Ankerscheibe schneller demontierbar.
Die Demontagearbeit und die Stillstandszeit der Fahrtreppen bei einem Hauptwellenlagertausch werden dadurch wesentlich verkürzt.The present invention represents a significant simplification of the Wellendemontagemethode, because the shaft bearing 7 is simpler in design than before and is faster disassembled by the principle pot and armature disc.
The dismantling work and the downtime of the escalators in a main shaft bearing replacement are significantly shortened.

Die Vorteile bei der Demontage liegen auf der Hand. Es braucht nur die Topfscheibe 9 von der Ankerscheibe 8 geschoben (Schiebepassung, Schiebesitz, Bewegungspassung, Bewegungssitz) zu werden und die Hauptwelle 5 ist vollkommen frei beweglich und kann ausgebaut bzw. ausgetauscht werden.The advantages of disassembly are obvious. It only needs the cup wheel 9 pushed by the anchor plate 8 (push fit, sliding seat, motion fit, moving seat) and the main shaft 5 is completely free to move and can be removed or replaced.

Bei der Montage der Hauptwelle 5 funktioniert das Prinzip genau umgekehrt. Die Topfscheibe 9 muss über die Ankerscheibe 8 geschoben werden.When mounting the main shaft 5, the principle works the other way around. The cup wheel 9 must be pushed over the armature disk 8.

Nach dem beiliegenden Ausführungsbeispiel der Erfindung wird die Welle 5 der Fahrtreppe bzw. Fahrsteiges über die Wellenlagerung 7 im Fachwerk 4 gelagert, indem die Ankerscheibe 8 der Wellenlagerung 7 fest mit dem Fachwerk 4 verbunden wird, die Topfscheibe 9 der Wellenlagerung 7 auf die Welle 5 gesetzt wird, die Welle 5 in einer definitiven Position positioniert wird, die Topfscheibe 9 längs der Welle auf die Ankerscheibe 8 geschoben und mit der Ankerscheibe 8 verbunden wird.After the enclosed embodiment of the invention, the shaft 5 of the escalator or moving walk is stored on the shaft bearing 7 in the framework 4 by the armature disk 8 of the shaft bearing 7 is firmly connected to the framework 4, the cup washer 9 of the shaft bearing 7 is placed on the shaft 5 is, the shaft 5 is positioned in a definitive position, the cup wheel 9 is pushed along the shaft on the armature disk 8 and connected to the armature disk 8.

Dadurch wird die Hauptwelle 5 über die Ankerscheibe 8 mit dem Fachwerk 4 verbunden. Die Hauptwelle 5 ist nun fix zusammengefügt bzw. eingebaut. Die Auflagerkräfte können nun von der Hauptwelle 5 über die Topfscheibe 9 zur Ankerscheibe 8 weitergeleitet werden. Die Ankerscheibe 8 leitet die Auflagerkräfte in das Fachwerk 4 ein bzw. gibt die Auflagerkräfte an das Fachwerk 4 weiter.As a result, the main shaft 5 is connected to the framework 4 via the armature disk 8. The main shaft 5 is now fixed together or installed. The support forces can now be forwarded from the main shaft 5 via the cup wheel 9 to the armature disk 8. The armature disk 8 initiates the bearing forces in the truss 4 or gives the support forces to the truss 4 on.
