Description

Die vorliegende Erfindung betrifft einen Seilaufzug gemäß dem Oberbegriff von Anspruch 1.The present invention relates to a cable lift according to the preamble of claim 1.

EP-A-0 202 525 offenbart einen gattungsgemäßen Seilaufzug.EP-A-0 202 525 discloses a generic cable lift.

Ein Aufzugsantrieb der genannten Art ist 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 known from DE 37 37 773 C2 known. In this construction, the assembly of the Gear simply, as well as the attachment and removal of the engine in a short time Time be possible, with the bearings remain aligned. The standing on the gearbox engine points to his Upside down 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.In today's high thermal load of the motor windings the onset of a winding defect appears due to overload more likely to be a mechanical defect in the transmission. If now a defective engine must be replaced, must with the defective engine and the brake located above the engine be reduced. The latter requires that for the time being, for example to be attached by means of cable clips and / or supporting the Counterweight in the shaft, the cabin and the counterweight against unbraked 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 a Elevator drive, consisting of a worm gear and a also standing engine, with the engine External rotor motor is and its cylindrical surface simultaneously 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 also has to change the engine Brake are degraded, bringing the same adverse effect arises as previously described. In addition, the by the outer rotor principle resulting large flywheel the acceleration and deceleration of the elevator car 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 let in relation to Gear size small motors conclude that these drives are designed only for relatively small benefits. In the Using a more powerful and thus larger engine for the middle power range can be the transmission base partially outstanding engine layout a correspondingly larger Require space for the drive, which is detrimental to the Scheduling options.

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 whose motor and Transmission housing dimensions are narrow, i. in at least one horizontal dimensions have such a small extent that the drive can be arranged laterally to save space in the shaft can, with conventional engine shapes are used. Continue to the engine without the disadvantages mentioned quickly and easily be interchangeable.

Der erfindungsgemässe Aufzugsantrieb zeichnet sich durch die kennzeichnenden Merkmale von Anspruch 1 aus.The elevator drive according to the invention is characterized by the characterizing features of claim 1.

Vorteilhafte Weiterbildungen und Verbesserungen sind in den Unteransprüchen aufgeführt.Advantageous 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 by the mounting feet on the gearbox in a to the transmission base are arranged according 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 engine Gearbox and must not be dismantled when changing the engine. Therefore, the drive, or the traction sheave after the Removing the motor blocked by 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 brake receiving housing part is as upward Directional flange collar with a flange plate for receiving of the engine is designed and, together with the Gear lower part, 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 optimized for great strength and rigidity, oval-like Vertical cross section of the gearbox housing, its curves different radii are formed and its height greater than its width allows thin wall thicknesses and thus a small lateral extent of the gear housing.

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 allows the use of a flywheel, which over the motor housing cross-section protrudes without exceeding the mounting mass.

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 by way of example a shaft assembly.

In Fig.1 It can also be seen that the engine 1 is not exactly vertical, but slightly different from the vertical tilted backwards 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 in the following 2 explained in more detail. The active transmission parts, one Worm 20 and with the worm 20 engaged Worm wheel 27, are in an oil-tight closed, about rectangular shaped cavity in the lower part of a Gear housing 28 installed. The worm 20 is part a motor / worm shaft 19, which at the lower end with a Fixed bearing 30 is held radially and axially in the transmission housing 28 and at the upper exit from this part of the transmission housing 28th is guided with a movable bearing 29. The worm wheel 27 is with a traction sheave shaft 35 rotatably connected. This part of the Transmission housing 28 is right with a gear cover 31st closed, has at the lowest point an oil drain plug 32 and is up to a level 33 with a transmission oil 34 filled. This lower part of the transmission housing 28 is, together with the upwardly extending flange collar 8 with Flange plate 38, designed 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.Right next to 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 called. Above of the movable bearing 29 and within the flange collar 8 is the Brake drum 5 is arranged and fixed with the motor / worm shaft 19 connected. With the flange plate 38 is a motor housing 24 of the Motors 1, preferably by means of screws, releasably connected. The Motor housing 24 comprises a laminated stator core 23 with a Stator winding 22, the lower ends, or their winding heads protrude into the flange collar 8. On the engine / worm shaft 19 is located in the region of the stator 23 for a 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.Against the upper end of the motor / worm shaft 19 above the Rotor 21 are on this a fan 25 and a flywheel 9 rotatably mounted and secured axially with a screw 40. With 36 is a screwed on the flywheel 9 Bevel gear ring called. The air outlet opening on the circumference of Fan wheel 25 is covered with a fan grill 26. With β is the existing skew angle to the vertical designated. The skew angle β may be that amount Have degrees by means of which the mentioned advantages be achieved. In the example shown, the angle β is about 10 °. The level of a designated 39 transmission floor is with the equal angle β inclined 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 of Figure 3 also shows the parts Hand drive shaft 44, pivot mechanism 43 and bevel pinion 42, and the mentioned bevel gear ring 36 of a manually operated Evacuating. Furthermore, the oval-like shape of the Getriebes 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 engine 1 clearly. Because of that in the vertical line of the engine 1, the gear housing base not towered over, this elevator drive can be correspondingly close to a Shaft wall 41 will be placed because the expansion across the Guide rail level, so the horizontal extent of the Drive between shaft wall and cab driving profile accordingly narrow. Furthermore, an attached below elevator car at the right side of the elevator drive according to Figure 4 along the Cabin guide rails 17 to over the engine 1 of Lift elevator drive out.

    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 at 2 marked in the interface of the transmission housing 28th This Figure 5 shows a for this transmission 2 in terms of strength and torsional rigidity optimal contour of the housing wall. The outer casing contour has a height h, which is greater as the width b. The determined by the method finite elements Housing contour has in its course in the example shown four different radii R1-R4 on, with the number in each other passing radii may 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 which, in turn, favor the exterior 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 in the Details not only on the example shown. So is For example, the mechanical brake as a disc brake with the appropriate fittings executable.

    Der Motor 1 kann eine von der gezeigten Ausführung abweichende Grösse und Form aufweisen. The engine 1 may differ from the embodiment shown Have size and shape.
