Description

Die Erfindung betrifft eine Lagervorrichtung für die Winde des Fahrkorbes eines Personen- oder Lastenaufzuges, mit einem Getriebegehäuse, in welchem die angetriebene Schnecke und das mit der Treibscheibe verbundene und mit der Schnecke kämmende Schneckenrad angeordnet sind.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 the driven worm and the worm wheel connected to the traction sheave and meshing with the worm are arranged.

Es ist bekannt, daß der Fahrkorb eines Personen- oder Lastenaufzuges durch eine Winde betätigt wird, die meist am oberen Ende des Aufzugsschachtes 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 Schnekkenwelle 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 freight elevator is operated by a winch, which is usually arranged at the upper end of the elevator shaft and essentially consists 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 is usually two brakes provided with brake pad materials has jaws, which are held with the help of electromagnets against spring forces in the open position, so that the brake responds automatically 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, welche 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 specific 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.

Der Erfindung liegt die Aufgabe zugrunde, eine Lagervorrichtung für die Winde des Fahrkorbes eines Personen- oder Lastenaufzuges der eingangs genannten Art zu schaffen, die eine schnelle und sichere Montage mit relativ geringen Kosten innerhalb kurzer Zeit zuläßt, und gewährleistet, daß das Gehäuse spannungsfrei auf dem Fundament montiert wird und infolgedessen ein erhöhter Verschleiß der Getriebeteile vermieden wird.The invention has for its object to provide a storage device for the winch of the car of a passenger or goods lift of the type mentioned, which allows quick and safe assembly at a relatively low cost in a short time, and ensures that the housing is stress-free on the Foundation is installed and consequently increased wear of the gear parts is avoided.

Diese Aufgabe wird gemäß der Erfindung durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich durch die Merkmale der Unteransprüche.This object is achieved according to the invention by the features specified in the characterizing part of claim 1. More before Partial configurations result from the features of the subclaims.

Gemäß der Erfindung wird vorgeschlagen, daß das Getriebegehäuse des Windenuntersetzungsgetriebes an seiner einen Seite mittels einer Schwenkverbindung irgendeiner Art abgestützt ist und auf der Scheibenseite verankert ist, so daß die ganze Windeneinrichtung nur einen Freiheitsgrad besitzt, der einer Schwenkbewegung an der Schwenkverbindung entspricht. Dabei kann diese Schwenkverbindung entweder durch ein Scharnier gebildet sein, wobei eine in wenigstens einer Lagerschale des Getriebegehäuses gelagerte Achse in zwei Lager von zwei Stützkonsolen eingreift, die beidseitig des Gehäuses angeordnet und mit dem Fundament verschraubbar sind. Die Scharnierachse ist orthogonal zur Hohlwelle des Getriebes angeordnet, welche das Schneckenrad mit der Treibscheibe verbindet, und die gegenüberliegende Lagereinrichtung ist von einer Stützkonsole gebildet, die ebenfalls mit dem Fundament verschraubbar ist. Die drei Stützkonsolen befinden sich an den Ecken eines gleichschenkeligen Dreiecks, wobei die Scharnierachse die Hypotenuse bildet, so daß das Getriebe mittels einer Dreipunktlagerung gegenüber dem Fundament abgestützt 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 swivel connection of some kind and is anchored on the disk side, so that the entire winch device has only one degree of freedom which corresponds to a swivel movement on the swivel connection. This pivot connection can either be formed by a hinge, an axle mounted in at least one bearing shell of the transmission housing engaging in two bearings of two support brackets which are arranged on both sides of the housing and can be screwed to the foundation. The hinge axis is arranged orthogonally to the hollow shaft of the gearbox, which connects the worm wheel to the traction sheave, and the opposite bearing device is formed by a support bracket, which can also be screwed to the foundation. The three support brackets are located at the corners of an isosceles triangle, the hinge axis forming the hypotenuse, so that the gear is supported against the foundation by means of a three-point bearing.

Es kann gemäß einem weiteren vorteilhaften Merkmal der Erfindung auch vorgesehen sein, daß die Scharnierachse geteilt ist und von wenigstens zwei Halbrundprofilen gebildet ist, die in Kehlnuten des Gehäusebodens formschlüssig gelagert sind und mit ihrer Flachseite auf einer Unterkonstruktion aufliegen. Wenn nun das Getriebegehäuse auf die Halbrundprofile aufgesetzt wird 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 darüber hinaus mit zwei orthogonal angeordneten planen Montageflächen ausgestattet sein, so daß es einmal in horizontaler liegender Lage oder in vertikaler stehender Lage montierbar ist.According to a further advantageous feature of the invention, it can also be provided that the hinge axis is divided and is formed by at least two semicircular profiles which are positively mounted in the groove grooves of the housing base and rest with their flat side on a substructure. If the gearbox is now placed on the semicircular profiles and is 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 have two orthogonally arranged flat mounting surfaces be equipped so that it can be installed in a horizontal position or in a vertical standing position.

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

Further features, details and advantages of the invention result from the following description of two preferred exemplary embodiments with reference to the drawing. In it show:
  • 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 II-II. Of Fig. 1;
  • 3 shows a side view of a further preferred exemplary embodiment for a winch gear with storage according to the invention in a horizontal position and in a vertical position;
  • Fig. 4 is a plan view of the transmission shown in Fig. 3, and
  • Fig. 5 is a partial section through the housing of the transmission shown in Fig. 3 on an enlarged 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 Schnekkenrad 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 durch eine eine Schwenkbewegung zulassende Achse 23 verbunden sind. Diese Achse oder Drehzapfen erstreckt 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, und der Achse 23 ein Scharnier gebildet wird, um welches das Gehäuse 4 schwenkbar ist. Aus den Figuren 1 und 2 ist im übrigen auch zu entnehmen, daß die beiden Achsen 19 und 23 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 rope 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 mounted on a stationary axis 19 with the aid of the bearing 15 and a sliding bearing 18. The left end of the fixed axis 19 in relation to FIG. 2 is supported with the aid of a bracket 20 on a concrete slab serving as the foundation 21, while the other end is firmly connected to the housing 4 of the reduction gear with the aid 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 connected to the housing by an axis 23 which allows a pivoting movement. This axis or pivot extends over the entire length of the housing 4, so that by means of the housing and the two support brackets 22, which can be screwed to the concrete slab 21, and the axis 23, a hinge is formed, around which the housing 4 can be pivoted. It can also be seen from FIGS. 1 and 2 that the two axes 19 and 23 are arranged orthogonally to one another.

Das in den Figuren 3 bis 5 gezeigte Ausführungsbeispiel für eine weitere erfindungsgemäße Getriebelagerung ist besonders durch die einfache Ausführung und Herstellung der Lagerung gekennzeichnet, die ebenso wie die Scharnierlagerung nach den Figuren 1 und 2 die Anforderungen an eine spannungsfreie, einfache und schnelle Montage des Getriebegehäuses auf der Unterkonstruktion erfüllt.The exemplary embodiment shown in FIGS. 3 to 5 for a further gearbox mounting according to the invention is particularly characterized by the simple design and manufacture of the mounting, which, like the hinge mounting according to FIGS. 1 and 2, meets the requirements for tension-free, simple and quick mounting of the gearbox housing the substructure.

Die Fig. 3 zeigt in der Seitenansicht das Getriebegehäuse 24 in zwei Stellungen, nämlich mit ausgezogenen Linien in der Horizontalstellung und mit dem Raster in der Vertikalstellung. Die Anordnung des Getriebegehäuses 24 in diesen beiden Stellungen wird dadurch ermöglicht, daß das Getriebegehäuse zwei plane Montageflächen 25, 26 besitzt, in denen nicht dargestellte Bohrungen für Gewindebolzen vorgesehen sein können.3 shows a side view of the transmission housing 24 in two positions, namely with solid lines in the horizontal position and with the grid in the vertical position. The arrangement of the gear housing 24 in these two positions is made possible in that the gear housing has two flat mounting surfaces 25, 26, in which bores for threaded bolts, not shown, can be provided.

Die Lagerung des Getriebegehäuses nach dem zweiten Ausführungsbeispiel erfolgt auf Halbrundprofilen 27, welche in Kehlnuten 28 des Getriebegehäuses 24 formschlüssig aufgenommen werden. Die Kehlnut 28 ist in der Montagefläche'25 vorgesehen, während die Kehlnut 29 in der Montagefläche 26 vorgesehen ist. 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 gear housing according to the second exemplary embodiment is mounted on semicircular profiles 27, which are received in a form-fitting manner in fillet grooves 28 of the gear housing 24. The fillet groove 28 is provided in the mounting surface 25, while the fillet groove 29 is provided in the mounting surface 26. 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 Stützkonsole 20 getragen wird, während das Gehäuse auf der gegenüberliegenden Seite entweder durch ein Scharnier oder 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 support bracket 20, while the housing on the opposite side either by a hinge or is supported by 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 stress-free assembly of the gear housing, which does not require any skilled workers.
