Description

Die vorliegende Erfindung betrifft einen Seilaufzug mit einem Aufzugsantrieb, bestehend aus einem Getriebe mit Treibscheibe, einem Motor, einer Bremse und über die Treibscheibe geschlungene Tragorgane für die Vertikalbewegung einer Aufzugskabine, vorzugsweise mit einem Gegengewicht, wobei der Motor des Aufzugantriebes nach oben gerichtet angeordnet ist.The present invention relates to a cable elevator with a Elevator drive, consisting of a gear with a traction sheave, a motor, a brake, and a loop wound over the traction sheave Supporting elements for the vertical movement of an elevator car, preferably with a counterweight, the motor of the Elevator drive is arranged upward.

Ein derartiger Seilaufzug ist bereits aus der EP-A-0 202 525 bekannt.Such a cable elevator is already known from EP-A-0 202 525.

Ein Aufzugsantrieb der genannten Art ist auch aus der DE 37 37 773 C2 bekannt. Bei dieser Konstruktion soll der Zusammenbau des Getriebes einfach, sowie das An- und Abbauen des Motors in kurzer Zeit möglich sein, wobei die Lager hierbei ausgefluchtet bleiben. Der stehend auf dem Getriebe angeordnete Motor weist auf seiner Oberseite eine Trommelbremse auf.An elevator drive of the type mentioned is also from DE 37 37 773 C2 known. In this construction, the assembly of the Gearbox simple, and the mounting and dismounting of the engine in a short time Time may be possible, whereby the bearings remain aligned. The motor, which is arranged on the transmission, points to it Top of a drum brake.

Bei der heute hohen thermischen Belastung der Motorwicklungen scheint das Eintreten eines Wicklungsdefektes infolge Ueberlastung wahrscheinlicher zu sein als ein mechanischer Defekt im Getriebe. Muss nun ein defekter Motor ausgewechselt werden, muss mit dem defekten Motor auch die oberhalb des Motors befindliche Bremse abgebaut werden. Letzteres bedingt dass vorerst, beispielsweise mittels anzubringenden Seilklammern und/oder Abstützen des Gegengewichtes im Schacht, die Kabine und das Gegengewicht gegen ungebremste Bewegungen gesichert werden müssen. Diese Prozedur ist zeitaufwendig und birgt Unfallrisiken.With today's high thermal load on the motor windings seems the occurrence of a winding defect due to overload to be more likely than a mechanical defect in the transmission. If a defective motor now needs to be replaced, use the defective engine including the brake located above the engine be dismantled. The latter means that for the time being, for example by means of attached rope clips and / or supporting the Counterweight in the shaft, the cabin and the counterweight against unrestrained movements must be secured. This procedure is time-consuming and involves accident risks.

Das deutsche Gebrauchsmuster 1 918 376 offenbart einen Aufzugsantrieb, bestehend aus einem Schneckengetriebe und einem ebenfalls stehend angeordneten Motor, wobei der Motor ein Aussenläufermotor ist und seine zylindrische Mantelfläche gleichzeitig als Bremstrommel dient.German utility model 1 918 376 discloses one Elevator drive, consisting of a worm gear and a also arranged upright engine, the engine on External rotor motor and its cylindrical outer surface also serves as a brake drum.

Bei diesem Antrieb muss bei einem Motorenwechsel ebenfalls die Bremse abgebaut werden, womit der gleiche nachteilige Effekt entsteht wie bereits vorhergehend beschrieben. Zudem kann die durch das Aussenläuferprinzip sich ergebende grosse Schwungmasse das Beschleunigen und Verzögern der Aufzugskabine ungünstig beeinflussen.With this drive, the must also when changing the engine Brake are dismantled, which has the same adverse effect arises as previously described. In addition, the large flywheel mass resulting from the outrunner principle accelerating and decelerating the elevator car is unfavorable influence.

Bei beiden genannten Antrieben lassen die im Verhältnis zur Getriebegrösse kleinen Motoren den Schluss zu, dass diese Antriebe nur für relativ kleine Leistungen ausgelegt sind. Bei der Verwendung eines leistungsstärkeren und somit grösseren Motors für den mittleren Leistungsbereich kann ein die Getriebegrundfläche teilweise überragender Motorgrundriss einen entsprechend grösseren Platzbedarf für den Antrieb bedingen, was sich nachteilig auf die Dispositionsmöglichkeiten auswirkt.In both drives mentioned in relation to Gearbox size small motors conclude that these drives are only designed for relatively small outputs. In the Use of a more powerful and therefore larger motor for the medium power range can be the gear unit base partially outstanding engine layout a correspondingly larger one Space requirements for the drive cause what is disadvantageous on the Disposition options affects.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde einen Aufzugsantrieb zu schaffen, dessen Motor- und Getriebegehäuseabmessungen schmal sind, d.h. in mindestens einer horizontalen Dimension eine solch geringe Ausdehnung haben, dass der Antrieb seitlich platzsparend im Schacht angeordnet werden kann, wobei übliche Motorenformen Verwendung finden. Weiter soll der Motor ohne die genannten Nachteile schnell und einfach auswechselbar sein.The present invention is therefore based on the object to create an elevator drive, the motor and Gearbox housing dimensions are narrow, i.e. in at least one horizontal dimension are so small that the drive can be arranged in the shaft to save space can, using common forms of engine. Should continue the engine quickly and easily without the disadvantages mentioned be interchangeable.

Der erfindungsgemässe Aufzugsantrieb zeichnet sich dadurch aus, dass der Aufzugsantrieb mit dem aufrecht angebauten Motor zur Vertikalen etwas geneigt angeordnet ist, derart, dass sich in der vertikalen Projektion von oben der Motor innerhalb der seitlichen Ausdehnung des Getriebes befindet und dass dies ohne aufwendige konstruktive Eingriffe möglich wird.The elevator drive according to the invention is characterized in that that the elevator drive with the motor mounted upright for Vertical is arranged somewhat inclined, such that in the vertical projection from above the motor inside the side Expansion of the gear is located and that this is without expensive constructive intervention is possible.

Vorteilhafte Weiterbildungen und Verbesserungen sind in den Unteransprüchen aufgeführt.Advantageous further developments and improvements are in the Subclaims listed.

Die Neigung der Motor-Getriebeachse wird dadurch erreicht, dass die Befestigungsfüsse am Getriebe in einer zur Getriebegrundfläche entsprechend geneigten Ebene angeordnet sind.The inclination of the motor-gear axis is achieved in that the mounting feet on the gearbox in a gearbox base are arranged according to the inclined plane.

Die mechanische Bremse befindet sich zwischen dem Motor und dem Getriebe und muss bei einem Motorenwechsel nicht abgebaut werden. Deshalb bleibt der Antrieb, bzw. die Treibscheibe nach dem Entfernen des Motors mittels der geschlossenen Bremse blockiert, womit keine zusätzlichen Sicherungsmassnahmen nötig sind.The mechanical brake is located between the engine and the Gearbox and does not have to be dismantled when changing the engine. Therefore, the drive or the traction sheave remains after Blocked motor removal by means of the closed brake, with which no additional security measures are necessary.

Die mechanische Bremse ist als fester Bestandteil des Getriebes ausgebildet und ist in einem Gehäuseteil des Getriebes angeordnet.The mechanical brake is an integral part of the transmission formed and is arranged in a housing part of the transmission.

Das die Bremse aufnehmende Gehäuseteil ist als nach oben gerichteter Flanschkragen mit einer Flanschplatte für die Aufnahme des Motors ausgebildet und ist, zusammen mit dem Getriebeunterteil, als ein einstückiges Gussgehäuse ausgebildet.The housing part that holds the brake is facing upwards Directed flange collar with a flange plate for the admission of the engine and is, together with the Lower part of the gearbox, designed as a one-piece cast housing.

Der für grosse Festigkeit und Steifigkeit optimierte, ovalähnliche Vertikalquerschnitt des Getriebegehäuses, dessen Rundungen aus verschiedenen Radien gebildet werden und dessen Höhe grösser als dessen Breite ist ermöglicht dünne Wandstärken und damit eine geringe seitliche Ausdehnung des Getriebegehäuses.The oval-like one, optimized for great strength and rigidity Vertical cross section of the gear housing, the curves of which different radii are formed and its height is greater than whose width is thin wall thicknesses and thus one low lateral expansion of the gearbox.

Die Anordnung einer Schwungmasse oberhalb des Motors ermöglicht die Verwendung einer Schwungscheibe, die über den Motorgehäusequerschnitt hinausragt, ohne die Einbaumasse zu überschreiten.The arrangement of a flywheel above the engine enables the use of a flywheel over the engine case cross section protrudes without exceeding the installation dimensions.

Der Aufzugsantrieb besteht aus einem Getriebe 2 mit einem nach oben sich erstreckenden, seitlich durchbrochenen Flanschkragen 8, welcher die mechanische Bremse enthält und einem oberhalb der Bremse aufgebauten Motor 1 mit einer Schwungscheibe 9. Die mechanische Bremse besteht aus einer Bremstrommel 5, einem Bremsmagnet 3 und Bremsbacken 4. Die Bremsbacken 4 wirken von aussen her durch seitliche Oeffnungen im Flanschkragenn 8 auf die Bremstrommel 5. Der Flanschkragen 8 ist oben mit einer Flanschplatte 38 abgeschlossen, auf welcher der Motor 1 angeschraubt ist. Das Getriebe 2 ist mittels seitlichen Befestigungsfüssen 10 mit horizontalen Getriebeträgern 11 und 12 lösbar verbunden. Seitlich des Getriebes 2 ist eine Treibscheibe 6 mit einer Abdeckung 7 angeordnet. Ueber die Treibscheibe 6 sind Tragorgane 18 geschlungen, welche eine nicht dargestellte Kabine und ein nicht dargestelltes Gegengewicht tragen. Die Getriebeträger 11 und 12 befinden sich auf einer horizontalen Traverse 13, welche ihrerseits über elastische Zwischenlagen 14 mit den Kabinenführungsschienen 17 und mit den Gegengewichtsführungsschienen 16 verbunden ist. Die aufgeführten Teile 11-14 bilden so eine Maschinenkonsole für den Aufzugsantrieb. In Fig.1 ist ferner ersichtlich, dass der Motor 1 nicht genau vertikal, sondern abweichend von der Vertikalen etwas nach hinten geneigt angeordnet ist.1 shows the elevator drive according to the invention using the example a shaft assembly. The elevator drive consists of one Transmission 2 with an upwardly extending, laterally perforated flange collar 8, which the mechanical brake contains and a motor 1 built above the brake with a flywheel 9. The mechanical brake consists of a Brake drum 5, a brake magnet 3 and brake shoes 4. The Brake shoes 4 act from the outside through lateral openings in the Flange collar 8 on the brake drum 5. The flange collar 8 is closed at the top with a flange plate 38 on which the Motor 1 is screwed on. The transmission 2 is by means of lateral Fastening feet 10 with horizontal gear supports 11 and 12 releasably connected. A traction sheave 6 is located on the side of the transmission 2 arranged with a cover 7. About the traction sheave 6 are Support members 18 looped, which is a cabin, not shown and carry a counterweight, not shown. The Transmission carriers 11 and 12 are on a horizontal Traverse 13, which in turn via elastic intermediate layers 14 with the car guide rails 17 and with the counterweight guide rails 16 is connected. The listed parts 11-14 thus form a machine console for the elevator drive. In Fig. 1 it can also be seen that the motor 1 is not exactly vertical, but deviating slightly from the vertical is arranged.

    Die weiteren Einzelheiten des Aufzugantriebes werden im folgenden anhand der Fig.2 näher erläutert. Die aktiven Getriebeteile, eine Schnecke 20 und ein mit der Schnecke 20 im Eingriff stehendes Schneckenrad 27, sind in einem öldicht geschlossenen, etwa rechteckig geformten Hohlraum im unteren Teil eines Getriebegehäuses 28 eingebaut. Die Schnecke 20 ist Bestandteil einer Motor/Schneckenwelle 19, welche am unteren Ende mit einem Festlager 30 radial und axial im Getriebegehäuse 28 gehalten ist und beim oberen Austritt aus diesem Teil des Getriebegehäuses 28 mit einem Loslager 29 geführt ist. Das Schneckenrad 27 ist mit einer Treibscheibenwelle 35 drehfest verbunden. Dieser Teil des Getriebegehäuses 28 ist rechts mit einem Getriebedeckel 31 verschlossen, weist an der tiefsten Stelle eine Oelablassschraube 32 auf und ist bis zu einem Niveau 33 mit einem Getriebeöl 34 gefüllt. Dieser untere Teil des Getriebegehäuses 28 ist, zusammen mit dem nach oben sich erstreckenden Flanschkragen 8 mit Flanschplatte 38, als einstückiges Gussgehäuse ausgebildet. The further details of the elevator drive are as follows explained in more detail with reference to FIG. The active transmission parts, one Auger 20 and one engaging with auger 20 Worm gear 27 are closed in an oil-tight, for example rectangular shaped cavity in the lower part of a Gear housing 28 installed. The screw 20 is a component a motor / worm shaft 19, which with a Fixed bearing 30 is held radially and axially in the gear housing 28 and at the upper exit from this part of the transmission housing 28 is guided with a floating bearing 29. The worm wheel 27 is with a traction sheave shaft 35 rotatably connected. This part of the Gear housing 28 is on the right with a gear cover 31 locked, has an oil drain screw at the lowest point 32 and is up to a level 33 with a gear oil 34 filled. This lower part of the gearbox 28 is together with the flange collar 8 extending upwards Flange plate 38, formed as a one-piece cast housing.

    Rechts neben dem Flanschkragen 8 ist auf einem flachen Teil des Getriebegehäuses 28 der Bremsmagnet 3 befestigt. Mit 37 ist ein Handlüfthebel für das manuelle Bremslüften bezeichnet. Oberhalb des Loslagers 29 und innerhalb des Flanschkragens 8 ist die Bremstrommel 5 angeordnet und mit der Motor/Schneckenwelle 19 fest verbunden. Mit der Flanschplatte 38 ist ein Motorgehäuse 24 des Motors 1, vorzugsweise mittels Schrauben, lösbar verbunden. Das Motorgehäuse 24 umfasst ein geblechtes Statorpaket 23 mit einer Statorwicklung 22, deren untere Enden, bzw. deren Wicklungsköpfe in den Flanschkragen 8 hineinragen. Auf der Motor/Schneckenwelle 19 befindet sich im Bereich des Statorpaketes 23 ein für Wechselstrommotoren typischer Rotor 21 mit Blechpaket und Kurzschlusswicklung.To the right of the flange collar 8 is on a flat part of the Gear housing 28 of the brake magnet 3 attached. At 37 is one Manual release lever for manual brake release. Above of the floating bearing 29 and within the flange collar 8 is the Brake drum 5 arranged and fixed to the motor / worm shaft 19 connected. With the flange plate 38 is a motor housing 24 of the Motor 1, preferably by means of screws, releasably connected. The Motor housing 24 comprises a laminated stator package 23 with one Stator winding 22, the lower ends, or the winding heads protrude into the flange collar 8. On the motor / worm shaft 19 is located in the area of the stator package 23 for AC motors typical rotor 21 with laminated core and Short-circuit winding.

    Gegen das obere Ende der Motor/Schneckenwelle 19 oberhalb des Rotors 21 sind auf dieser ein Lüfterrad 25 und eine Schwungscheibe 9 drehfest angebracht und mit einer Schraube 40 achsial gesichert. Mit 36 ist ein auf der Schwungscheibe 9 aufgeschraubter Kegelradring bezeichnet. Die Luftaustrittsöffnung am Umfang des Lüfterrades 25 ist mit einem Lüftergitter 26 abgedeckt. Mit β ist der zur Vertikalen vorhandene Schrägstellungswinkel bezeichnet. Der Schrägstellungswinkel β kann jenen Betrag Winkelgrade aufweisen mittels welchem die erwähnten Vorteile erzielt werden. Im gezeigten Beispiel beträgt der Winkel β ca 10°. Die Ebene eines mit 39 bezeichneten Getriebebodens ist mit dem gleichen Winkel β zur horizontalen Ebene geneigt.Towards the upper end of the motor / worm shaft 19 above the Rotors 21 are a fan wheel 25 and a flywheel on this 9 rotatably attached and secured axially with a screw 40. At 36 is a screwed onto the flywheel 9 Designated bevel gear ring. The air outlet opening on the circumference of the Fan wheel 25 is covered with a fan grill 26. With β is the inclination angle to the vertical designated. The angle of inclination β can be that amount Angular degrees have the advantages mentioned be achieved. In the example shown, the angle β is approximately 10 °. The level of a gearbox floor designated 39 is with the inclined at the same angle β to the horizontal plane.

    Die Frontansicht,der Fig.3 zeigt zusätzlich die Teile Handantriebswelle 44, Schwenkmechanik 43 und Kegelritzel 42, sowie den erwähnten Kegelradring 36 einer manuell betätigbaren Evakuiervorrichtung. Ferner ist die ovalähnliche Form des Getriebes mit dem Getriebedeckel 31 erkennbar.The front view, Fig.3 also shows the parts Manual drive shaft 44, swivel mechanism 43 and bevel pinion 42, as well said bevel gear ring 36 a manually operated Evacuating. Furthermore, the oval-like shape of the Gearbox with the gear cover 31 recognizable.

    In der Fig.4 wird der Vorteil mit dem Winkel β von der Vertikalen abweichenden Achse des Motors 1 deutlich. Dadurch, dass in der vertikalen Linie der Motor 1 die Getriebegehäusegrundfläche nicht überragt, kann dieser Aufzugsantrieb entsprechend nahe an eine Schachtwand 41 plaziert werden, weil die Ausdehnung quer zur Führungsschienenebene, also die horizontale Erstreckung des Antriebes zwischen Schachtwand und Kabinenfahrprofil entsprechend schmal ist. Ferner kann eine unten angehängte Aufzugskabine an der rechten Seite des Aufzugantriebes gemäss Fig.4 entlang der Kabinenführungsschienen 17 bis über den Motor 1 des Aufzugantriebes hinaus hochfahren.In Figure 4, the advantage with the angle β from the vertical deviating axis of the motor 1 clearly. Because in the vertical line of the engine 1 does not affect the transmission case base towered over, this elevator drive can accordingly close to one Well wall 41 can be placed because the extension is transverse to Guide rail level, i.e. the horizontal extension of the Drive between shaft wall and cabin travel profile accordingly is narrow. Furthermore, an elevator car attached below can be attached to the right side of the elevator drive according to Figure 4 along the Cabin guide rails 17 to the engine 1 of the Raise the elevator drive.

    Die Fig.5 zeigt eine Querschnittsform der Getriebegehäuses 28 an der in der Fig.2 markierten Schnittstelle des Getriebegehäuses 28. Diese Fig.5 zeigt eine für dieses Getriebe 2 bezüglich Festigkeit und Torsionssteifigkeit optimale Kontur der Gehäusewand. Die äussere Gehäusekontur weist eine Höhe h auf, welche grösser ist als die Breite b. Die nach der Methode Finite Elemente ermittelte Gehäusekontur weist in ihrem Verlauf im gezeigten Beispiel vier verschiedene Radien R1-R4 auf, wobei die Anzahl ineinander übergehende Radien grösser oder kleiner als vier sein können. Es ergibt sich so eine ovalähnliche Querschnittsform der Gehäusewand. Des weiteren kann die Gehäusewandstärke relativ klein gehalten werden, was sich wiederum günstig auf die Aussenabmessungen und auch auf das Gewicht des Getriebes 2 auswirkt.5 shows a cross-sectional shape of the transmission housing 28 the interface of the transmission housing 28 marked in FIG. 2. This Figure 5 shows a strength for this gear 2 and torsional rigidity optimal contour of the housing wall. The outer housing contour has a height h, which is larger than the width b. The determined using the finite element method Housing contour has four in its course in the example shown different radii R1-R4, the number inside each other transition radii can be greater or less than four. It this results in an oval-like cross-sectional shape of the housing wall. Furthermore, the housing wall thickness can be kept relatively small be, which in turn is favorable to the external dimensions and also affects the weight of the transmission 2.

    Die Konstruktion des Aufzugantriebes beschränkt sich in den Einzelheiten nicht nur auf das gezeigte Beispiel. So ist beispielsweise die mechanische Bremse auch als Scheibenbremse mit den entsprechenden Armaturen ausführbar.The construction of the elevator drive is limited to Details not only on the example shown. So is for example, the mechanical brake with a disc brake the corresponding fittings can be executed.

    Der Motor 1 kann eine von der gezeigten Ausführung abweichende Grösse und Form aufweisen. The engine 1 can be a different from the embodiment shown Show size and shape.
