Description

Die Erfindung betrifft eine Lagervorrichtung für die Winde des Fahrkorbes eines Personen- oder Lastenaufzuges, mit einem Getriebegehäuse, in welchem eine angetriebene Schnecke und ein über eine Welle mit einer außerhalb des Getriebegehäuses angeordneten Treibscheibe verbundenes und mit der Schnecke kämmendes Schneckenrad angeordnet sind, wobei die Lagervorrichtung ein Schwenklager für das Getriebegehäuse und ein durch eine Stützkonsole gebildetes Festlager aufweist.The invention relates to a bearing device for the winch of the elevator car of a passenger or goods lift, with a gear housing in which a driven worm and a worm wheel connected via a shaft to a worm gear arranged outside the gear housing and meshing with the worm are arranged, the bearing device has a pivot bearing for the gear housing and a fixed bearing formed by a support bracket.

Es ist bekannt, daß der Fahrkorb eines Personen- oder Lastenaufzuges durch eine Winde betätigt wird, die meist am oberen Ende des Aufzugschachtes angeordnet ist und im wesentlichen aus einem Untersetzungsgetriebe mit Schnecke und Schneckenrad besteht. Die Schnecke und das Schneckenrad sind in einem mit Öl gefüllten Getriebegehäuse gelagert. Die langsam laufende Schneckenradwelle des Getriebes ist mit einer Seilscheibe oder Treibscheibe verbunden, über welche die den Fahrkorb tragenden Seile laufen, während die schnell laufende Schneckenwelle fast immer mit einem als Drehstrommotor ausgebildeten Elektromotor in einer Antriebsverbindung steht. Die Winde ist ferner mit einer Bremsvorrichtung ausgestattet, die in der Regel zwei mit Bremsbelagwerkstoffen versehene Bremsbacken aufweist, welche mit Hilfe von Elektromagneten entgegen Federkräften in der Öffnungsstellung gehalten werden, so daß die Bremse automatisch beim Stromausfall anspricht und den Aufzug anhält.It is known that the car of a passenger or goods lift is operated by a winch, which is usually arranged at the upper end of the elevator shaft and consists essentially of a reduction gear with worm and worm wheel. The worm and worm wheel are stored in a gear housing filled with oil. The slow-running worm wheel shaft of the transmission is connected to a rope pulley or traction sheave over which the cables carrying the car run, while the fast-running worm shaft is almost always in a drive connection with an electric motor designed as a three-phase motor. The winch is also equipped with a braking device, which usually has two brake shoes provided with brake pad materials, which are held in the open position by means of electromagnets against spring forces, so that the brake automatically responds in the event of a power failure and stops the elevator.

Eines der am häufigsten vorkommenden Montage- und Einbauprobleme bei Aufzugswinden liegt in der Notwendigkeit, die Achse, die die sich drehenden Teile trägt, möglichst in einer bestimmten Stellung mit kleinsten Toleranzen anzuordnen, damit die Scheibe und mit ihr das Schneckenrad, die auf nicht vollkommen miteinander horizontal fluchtenden und vertikal ausgerichteten Abstützungen getragen sind, nicht einem unzulässigen Verschleiß ausgesetzt sind, der dazu führen kann, daß die das Schneckenrad und die Tragscheibe miteinander verbindende Hohlwelle einem Dauerbruch zum Opfer fällt.One of the most common assembly and installation problems with elevator winches is the need to position the axis that carries the rotating parts in a certain position with the smallest tolerances, so that the disc and with it the worm wheel that are not perfectly aligned horizontally aligned and vertically aligned supports are not exposed to inadmissible wear, which can lead to the hollow shaft connecting the worm wheel and the supporting disk to a permanent failure.

Daraus folgt, daß bei einer herkömmlichen Winde die Abstützungen nur durch ausgebildete Fachleute montiert werden können, um eine einwandfreie fluchtende Lagerung zu erreichen, was bei hyperstatischen Ausführungsformen mit drei Abstützungen zu Zeitverlusten und zusätzlichen Kosten führt. Bei Windenausführungen mit einer gefederten Scheibe müssen die Wellen, die Abstützungen und das ihnen zugeordnete Gehäuse mit großem Übermaß konstruiert werden. Weiterhin muß der Rahmen, an dem diese Windenausführung sich abstützt, sehr sorgfältig dimensioniert werden, um das Kippmoment aufzunehmen.It follows that in a conventional winch the supports can only be installed by trained specialists in order to achieve a perfectly aligned bearing, which leads to loss of time and additional costs in hyperstatic embodiments with three supports. In the case of winch designs with a spring-loaded washer, the shafts, the supports and the housing assigned to them must be designed with a large oversize. Furthermore, the frame on which this winch version is supported must be dimensioned very carefully in order to absorb the tilting moment.

Aus der DE-B-12 69 317 ist bereits eine Lagervorrichtung der eingangs genannten Art bekannt, bei der eine Drehwelle in beiden Seitenwänden des Getriebegehäuses und in einer feststehenden Konsole gelagert ist. Das Getriebegehäuse, das die Drehwelle auf diese Weise hält, ruht mit seiner Unterseite auf einem Schwenklager auf, welches auch als Biegelager ausgebildet sein kann. Diese Ausbildung der bekannten Lagervorrichtung bewirkt, daß das gesamte Getriebegehäuse ständig leichte Schwenkbewegungen um das Schwenklager oder das Biegelager, auf dem es aufruht, ausführt, um die beiden seitlichen Lager in seinen Seitenwänden stets auf die sich drehende Welle auszurichten, um zu verhindern, daß durch diese Art der Lagerung zusätzliche Torsionsmomente in der Welle hervorgerufen werden. Dabei hat die Gesamtheit aus Getriebe, Getriebegehäuse und Drehwelle nur eine geringe Steifigkeit und Stabilität.From DE-B-12 69 317 a bearing device of the type mentioned is already known, in which a rotary shaft is mounted in both side walls of the gear housing and in a fixed bracket. The underside of the gear housing, which holds the rotary shaft in this way, rests on a swivel bearing, which can also be designed as a flexible bearing. This design of the known bearing device causes the entire gear housing to constantly carry out slight pivoting movements around the pivot bearing or the pivot bearing on which it rests, in order to always align the two side bearings in its side walls with the rotating shaft in order to prevent them from this type of bearing can cause additional torsional moments in the shaft. The assembly consisting of gearbox, gearbox housing and rotating shaft has only a low level of rigidity and stability.

Der Erfindung liegt die Aufgabe zugrunde, eine Lagervorrichtung der gattungsgemäßen Art zu schaffen, die eine schnelle und einfache sowie starre, jedoch spannungsfreie Montage des Lagergehäuses ermöglicht, derart, daß während des Betriebes keine zusätzlichen Momente und Kräfte in die Getriebeteile eingeleitet werden und damit deren erhöhter Verschleiß vermieden wird.The invention has for its object to provide a storage device of the generic type, which enables a quick and easy and rigid, but stress-free assembly of the bearing housing, such that no additional moments and forces are introduced into the transmission parts during operation and thus their increased Wear is avoided.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the features specified in the characterizing part of claim 1. Advantageous developments of the invention are characterized in the subclaims.

Gemäß der Erfindung wird vorgeschlagen, daß das Getriebegehäuse des Windenuntersetzungsgetriebes an seiner einen Seite mittels einer Schwenkverbindung abgestützt und auf der Scheibenseite verankert ist, so daß die ganze Windeneinrichtung einen Freiheitsgrad besitzt, der einer Schwenkbewegung an der Schwenkverbindung entspricht. Dabei ist diese Schwenkverbindung durch ein Halbrundprofil gebildet, das in einer Kehlnut des Gehäusebodens formschlüssig gelagert ist und mit seiner Flachseite auf einer Unterkonstruktion aufliegt. Das Halbrundprofil weist eine Durchgangsbohrung zur Aufnahme eines Gewindebolzens auf, mit dem das Getriebegehäuse auf der Unterkonstruktion festschraubbar ist. Die Schwenkachse ist orthogonal zur Hohlwelle des Getriebes, die das Schneckenrad mit der Treibscheibe verbindet, angeordnet, wobei die Hohlwelle auf einer feststehenden, mit dem Getriebegehäuse fest verbundenen Achse drehbar gelagert ist, die mit ihrem gehäusefreien Ende von der Stützkonsole gehalten ist. Die Unterkonstruktion kann durch wenigstens eine Stützkonsole gebildet sein, die mit dem Fundament verschraubbar ist.According to the invention it is proposed that the gear housing of the winch reduction gear is supported on one side by means of a pivot connection and anchored on the disc side, so that the entire winch device has a degree of freedom which corresponds to a pivoting movement on the pivot connection. This swivel connection is formed by a semicircular profile which is positively mounted in a groove in the housing base and rests with its flat side on a substructure. The semicircular profile has a through hole for receiving a threaded bolt, with which the gear housing can be screwed onto the substructure. The pivot axis is arranged orthogonally to the hollow shaft of the gearbox, which connects the worm wheel to the traction sheave, the hollow shaft being rotatably mounted on a fixed axle which is fixedly connected to the gearbox housing and which is held by the support bracket with its housing-free end. The substructure can be formed by at least one support bracket which can be screwed to the foundation.

Mit Vorteil kann vorgesehen sein, daß die Schwenkachse geteilt und von wenigstens zwei Halbrundprofilen gebildet ist. Die dann vorgesehenen drei Stützkonsolen können sich an den Ecken eines gleichschenkligen Dreiecks befinden, wobei die Schwenkachse die Hypotenuse bildet, so daß das Getriebe mittels einer Dreipunktlagerung gegenüber dem Fundament abgestützt ist.It can advantageously be provided that the pivot axis is divided and formed by at least two semicircular profiles. The then provided three support brackets can be located at the corners of an isosceles triangle, the pivot axis being the Hypotenuse forms, so that the gear is supported by means of a three-point bearing against the foundation.

Wenn nun das Getriebegehäuse auf die Halbrundprofile aufgesetzt und an der gegenüberliegenden Stützkonsole gegenüber dem Fundament festgesetzt wird, dann richtet es sich auf den Halbrundprofilen spannungsfrei aus, so daß es dann anschließend mit jeweils zwei Gewindebolzen am Fundament befestigt werden kann. Die Herstellung der Lagerschalen für die Halbrundprofile ist denkbar einfach mit Hilfe einer Fräsvorrichtung herstellbar. Das Gehäuse kann darüberhinaus mit zwei orthogonal angeordneten planen Montageflächen ausgestattet sein, so daß es einmal in horizontaler liegender Lage oder in vertikaler stehender Lage montierbar ist.If the gear housing is now placed on the semicircular profiles and attached to the opposite support bracket opposite the foundation, it aligns itself tension-free on the semicircular profiles, so that it can then be attached to the foundation with two threaded bolts. The production of the bearing shells for the semicircular profiles is very easy to manufacture using a milling device. The housing can also be equipped with two orthogonally arranged flat mounting surfaces, so that it can be installed in a horizontal position or in a vertical position.

Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung. Darin zeigen:

  • Fig. 2 eine Schnittansicht entlang der Linie 11-11 nach Fig. 1, und
  • Fig. 3 einen Teilschnitt durch das Gehäuse des Getriebes eines Details in vergrößertem

  • Figure 1 shows the winch device according to the invention in a partially sectioned side view.
  • Fig. 2 is a sectional view taken along the line 11-11 of Fig. 1, and
  • Fig. 3 shows a partial section through the housing of the transmission of a detail in an enlarged view

Scale.

Den Fig. 1 und 2 ist zu entnehmen, daß die Winde 1 eine Schnecke 2 und ein Schneckenrad 3 aufweist, die in einem ölgefüllten Gehäuse 4 angeordnet sind. Die Schnecke 2 ist an der schnell laufenden Welle 5 des Untersetzungsgetriebes befestigt, wobei ein Ende 6 der Welle in der vorderen Wand des Gehäuses 4 mittels eines Lagers 7 und das andere Ende in der hinteren Wand 8 mittels eines Lagers 9 und einer Sicherung 10 abgestützt ist. Auf dem freien Ende der schnell laufenden Welle 5 ist ein Rotor 11 eines Drehstrommotors 12 drehfest angebracht bzw. in der Nabe 13 der Bremse aufgenommen.1 and 2 that the winch 1 has a worm 2 and a worm wheel 3, which are arranged in an oil-filled housing 4. The worm 2 is fastened to the high-speed shaft 5 of the reduction gear, one end 6 of the shaft being supported in the front wall of the housing 4 by means of a bearing 7 and the other end in the rear wall 8 by means of a bearing 9 and a fuse 10 . On the free end of the high-speed shaft 5, a rotor 11 of a three-phase motor 12 is attached in a rotationally fixed manner or received in the hub 13 of the brake.

Aus der Fig. 2 ist zu entnehmen, daß das Schneckenrad 3 eine mittlere Hohlwelle 13 besitzt, welche die langsam laufende Welle des Untersetzungsgetriebes 4 bildet und mit dem Schneckenrad 3 einstückig verbunden ist. Die Hohlwelle 13 endet in einem Flansch 14, welcher auf einem Lager 15 gelagert ist und an welchem die Scheibe 16 mit Seilnuten 17 angeflanscht ist, in denen die Seile des Personen- und Lastenaufzuges laufen. Die Hohlwelle 13, welche das Schneckenrad 3 über den Flansch 14 mit der Scheibe 16 verbindet, ist mit Hilfe des Lagers 15 und eines Gleitlagers 18 auf einer stillstehenden Achse 19 drehbar gelagert. Das in bezug auf die Fig. 2 linke Ende der feststehenden Achse 19 ist mit Hilfe einer Konsole 20 auf einer als Fundament 21 dienenden Betonplatte abgestützt, während das andere Ende mit Hilfe von Schraubbolzen mit dem Gehäuse 4 des Untersetzungsgetriebes fest verbunden ist. Dieses Gehäuse 4 ist auf der Betonplatte 21 oder einer geeigneten Unterkonstruktion mit Hilfe von zwei Stützkonsolen 22 abgestützt, die mit dem Gehäuse schwenkbar verbunden sind. Diese Schwenkachse ersteckt sich über die ganze Länge des Gehäuses 4, so daß mittels des Gehäuses und der beiden Stützkonsolen 22, die mit der Betonplatte 21 verschraubbar sind, das Gehäuse 4 schwenkbar ist. Aus den Fig. 1 und 2 ist im übrigen auch zu entnehmen, daß diese Achse und die Achse 19 orthogonal zueinander angeordnet sind.From Fig. 2 it can be seen that the worm wheel 3 has a central hollow shaft 13 which forms the slow-running shaft of the reduction gear 4 and is integrally connected to the worm wheel 3. The hollow shaft 13 ends in a flange 14 which is mounted on a bearing 15 and on which the disc 16 is flanged with cable grooves 17 in which the ropes of the passenger and goods lift run. The hollow shaft 13, which connects the worm wheel 3 to the disk 16 via the flange 14, is rotatably supported on a stationary axis 19 with the aid of the bearing 15 and a slide bearing 18. The left end of the fixed axis 19 in relation to FIG. 2 is supported by means of a bracket 20 on a concrete slab serving as a foundation 21, while the other end is firmly connected to the housing 4 of the reduction gear by means of screw bolts. This housing 4 is supported on the concrete slab 21 or a suitable substructure with the aid of two support brackets 22 which are pivotally connected to the housing. This pivot axis extends over the entire length of the housing 4, so that the housing 4 can be pivoted by means of the housing and the two support brackets 22, which can be screwed to the concrete slab 21. 1 and 2 can also be seen that this axis and the axis 19 are arranged orthogonally to each other.

Die in Fig. 3 gezeigte Schwenkachse für die erfindungsgemäße Getriebelagerung ist besonders durch die einfache Ausführung und Herstellung der Lagerung gekennzeichnet, die ebenso wie die Scharnierlagerung auf den Stützkonsolen 22 nach den Fig. 1 und 2 die Anforderungen an eine spannungsfreie, einfache und schnelle Montage des Getriebegehäuses auf der Unterkonstruktion erfüllt.The pivot axis shown in FIG. 3 for the gearbox mounting according to the invention is particularly characterized by the simple design and manufacture of the mounting, which, like the hinge mounting on the support brackets 22 according to FIGS. 1 and 2, the requirements for a tension-free, simple and quick assembly of the Gearbox housing on the substructure met.

Die Anordnung des Getriebegehäuses 24 in der Horizontal- und Vertikalstellung wird dadurch ermöglicht, daß das Getriebegehäuse zwei plane Montageflächen besitzt, in denen Bohrungen für Gewindebolzen vorgesehen sein können.The arrangement of the gear housing 24 in the horizontal and vertical position is made possible in that the gear housing has two flat mounting surfaces, in which holes for threaded bolts can be provided.

Die Lagerung des Getriebegehäuses gemäß Figur 3 erfolgt auf Halbrundprofilen 27, welche in Kehlnuten 28 des Getriebegehäuses formschlüssig aufgenommen werden. Die Kehlnut 28 ist in der Montagefläche vorgesehen.The gear housing according to FIG. 3 is mounted on semicircular profiles 27, which are received in a form-fitting manner in fillet grooves 28 of the gear housing. The groove 28 is provided in the mounting surface.

Die Kehlnuten sind denkbar einfach mit Hilfe einer Fräsvorrichtung herzustellen. Die Halbrundprofile sind genormte Teile und im Fachhandel erhältlich. Die Halbrundprofile 27 liegen mit ihrer flachen Seite auf der Unterkonstruktion oder dem Fundament 30 auf. Wenn das Getriebe montiert wird, dann kann sich das Getriebegehäuse 4 auf den Halbrundprofilen 27 ausrichten, so daß eine einfache, spannungsfreie Montage ermöglicht wird. Die Halbrundprofile 27 besitzen jeweils zwei Durchgangsbohrungen, welche mit Hilfe von Gewindebolzen durchgriffen werden, so daß das Getriebegehäuse 24 nach dem Ausrichten an der Unterkonstruktion festgeschraubt werden kann.The fillet grooves are very easy to manufacture using a milling device. The semicircular profiles are standardized parts and are available from specialist dealers. The flat side of the semicircular profiles 27 rest on the substructure or the foundation 30. When the transmission is assembled, the transmission housing 4 can align itself on the semicircular profiles 27, so that simple, stress-free assembly is made possible. The semicircular profiles 27 each have two through holes, which are penetrated with the aid of threaded bolts, so that the gear housing 24 can be screwed to the substructure after alignment.

Aus der vorstehenden Beschreibung ist zu entnehmen, daß mit der erfindungsgemäßen Konstruktion der Lagervorrichtung der Winde eine einwandfreie Ausfluchtung der Abstützungen im wesentlichen dadurch erzielt wird, daß ein Ende der Tragachse 19 durch eine Konsole 20 getragen wird, während das Gehäuse auf der gegenüberliegenden Seite entweder durch halbrunde Profilteile abgestützt wird, die eine Bewegung des Gehäuses um einen Freiheitsgrad zulassen. Dies führt ganz offensichtlich zu einer erheblichen Einsparung von Montagezeit und zu einer spannungsfreien Montage des Getriebegehäuses, welche keine Fachkräfte erfordert.From the above description it can be seen that with the construction of the bearing device of the winch according to the invention a perfect alignment of the supports is essentially achieved in that one end of the support shaft 19 is supported by a bracket 20, while the housing on the opposite side either through is supported semicircular profile parts that allow movement of the housing by one degree of freedom. Obviously, this leads to a considerable saving in assembly time and to a tension-free assembly of the gear housing, which does not require any skilled workers.
