Description

Die vorliegende Erfindung betrifft ein Getriebegehäuse für eine Aufzugantriebseinheit gemäss dem Oberbegriff des Anspruchs 1 und ein Verfahren zum Zusammenbau einer Aufzugantriebseinheit mit einem Getriebegehäuse.The present invention relates to a gearbox for one Elevator drive unit according to the preamble of claim 1 and a method of assembling an elevator drive unit with a gearbox.

Ein Aufzugsantrieb 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 is from DE 37 37 773 C2 known. With this construction, the assembly should of the gearbox, as well as mounting and dismounting the engine be possible in a short period of time, the bearings being here stay aligned. The standing on the gear arranged motor has on its top Drum brake on.

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 Motor windings seem to be entering, one Winding defects due to overload are more likely be as a mechanical defect in the transmission. Must now defective motor must be replaced with the defective one Engine also the brake located above the engine be dismantled. The latter means that for the time being for example by means of rope clips to be attached and / or Supporting the counterweight in the shaft, the cabin and that Counterweight can be secured against unchecked movements have to. 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 motor also arranged upright, the motor is an external rotor motor and its cylindrical Shell 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.This drive must also be used when changing the motor the brake are dismantled, with the same disadvantage The effect arises as previously described. moreover can be the large one resulting from the external rotor principle Inertia the acceleration and deceleration of the Adversely affect elevator car.

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 Small engine size concludes that this Drives are only designed for relatively small outputs. When using a more powerful and therefore Larger motors for the medium power range can the gearbox base partially superior Motor layout a correspondingly larger space requirement for the drive condition, which adversely affects the Disposition options affects.

US 2351060 offenbart eine Aufzugantriebseinheit mit einem Schneckengetriebe. Das Schneckengetriebe umfasst ein Getriebegehäuse, in welchem eine Abtriebswelle horizontal gelagert ist und eine Motor-/ Schneckenwelle in einem rechten Winkel zur Abtriebswelle in auf einer gemeinsamen Achse liegenden eingesetzten Lagern gelagert ist, wobei ein Ende der Motor-/ Schneckenwelle in einem ersten Lager im Bodenbereich des Getriebegehäuses gelagert ist und ein zweites Lager in einer weiteren Lage angeordnet ist, und wobei das erste Lager ein von der Aussenseite des Getriebegehäuses her zugängliches, ausbaubares Festlager und das zweite Lager ein Loslager ist. Eine Schnecke ist mit der Motor-/Schneckenwelle verbunden. Ein mit der Schnecke kämmendes Schneckenrad ist mit einer Zwischenwelle verdrehfest verbunden, wobei die Zwischenwelle über ein Ritzel und eine innenverzahnte Treibscheibe mit der Abtriebswelle verbunden ist. Der Aufbau eines derartigen Schneckengetriebes ist kompliziert und der Zusammenbau einer solchen Aufzugantriebseinheit entsprechend aufwändig.US 2351060 discloses an elevator drive unit with a Worm gear. The worm gear includes one Gearbox housing in which an output shaft is horizontal is stored and a motor / worm shaft in one right angle to the output shaft in on a common Axial inserted bearings is mounted, with a End of the motor / worm shaft in a first bearing in Bottom area of the gear housing is mounted and a second bearing is arranged in a further position, and the first bearing one from the outside of the Gearbox housing accessible, removable fixed bearing and the second bearing is a floating bearing. A snail is with the Motor / worm shaft connected. One with the snail intermeshing worm wheel is with an intermediate shaft non-rotatably connected, the intermediate shaft via a Pinion and an internally toothed traction sheave with the Output shaft is connected. The structure of such Worm gear is complicated and assembling one such elevator drive unit correspondingly complex.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde einen Aufzugsantrieb zu schaffen, der ein Getriebe mit einer einfacheren Konstruktion aufweist und mit möglichst geringem Aufwand zusammengebaut werden kann. The present invention is therefore based on the object to create an elevator drive, the one Gearbox with a simpler construction and with can be assembled with as little effort as possible.

Diese Aufgabe wird gelöst durch ein Getriebegehäuse mit den Merkmalen des Anspruchs 1 und ein Verfahren zum Zusammenbau einer Aufzugantriebseinheit mit den Merkmalen des Anspruchs 9.This problem is solved by a gearbox with the Features of claim 1 and a method of assembly an elevator drive unit with the features of the claim 9th

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

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 when changing the engine be dismantled. Therefore, the drive, or the Traction sheave after removing the motor by means of the closed brake, which means 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 Gear designed and is in a housing part of the Gear arranged.

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 Engine trained and is, together with the Lower part of the gearbox as a one-piece cast housing educated.

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 gear housing, whose curves are formed from different radii and its height greater than its width is possible thin wall thicknesses and thus a low lateral Expansion of the gearbox.

Die Anordnung einer Schwungmasse oberhalb des Motors ermöglicht die Verwendung einer Schwungscheibe, die über den Motorgehäuse-querschnitt hinausragt, ohne die Einbaumasse zu überschreiten.The arrangement of a flywheel above the engine allows the use of a flywheel over the Motor housing cross section protrudes without the installation dimensions exceed.

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 following explained in more detail with reference to FIG. The active ones Gear parts, a worm 20 and one with the worm 20 engaged worm wheel 27 are in an oil tight closed, approximately rectangular shaped cavity in the lower Part of a gear housing 28 installed. The snail 20 is part of a motor / worm shaft 19, which on lower end with a fixed bearing 30 radially and axially in Gear housing 28 is held and at the top exit this part of the gear housing 28 with a floating bearing 29 is led. The worm wheel 27 is with a Traction sheave shaft 35 non-rotatably connected. This part of the Gear housing 28 is on the right with a gear cover 31 closed, has one at the lowest point Oil drain plug 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 up extending flange collar 8 with flange plate 38, as 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 the transmission housing 28 of the brake magnet 3 attached. At 37 is a manual release lever for manual brake release designated. Above the floating bearing 29 and within the Flange collar 8, the brake drum 5 is arranged and with the motor / worm shaft 19 firmly connected. With the Flange plate 38 is a motor housing 24 of motor 1, preferably detachably connected by means of screws. The Motor housing 24 also includes a laminated stator package 23 a stator winding 22, the lower ends of which Project winding heads into the flange collar 8. On the Motor / worm shaft 19 is in the area of Stator package 23 a rotor typical of AC motors 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 axial 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. Towards the upper end of the motor / worm shaft 19 above of the rotor 21 are a fan wheel 25 and a Flywheel 9 rotatably attached and with a screw 40 axially secured. At 36 there is one on the flywheel 9 screwed on bevel gear ring. The Air outlet opening on the circumference of the fan wheel 25 is with a fan grill 26 covered.

    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.With β is the vertical one Referred to inclination angle. The skew angle β can have that amount of angular degrees by means of which the advantages mentioned are achieved. In the example shown the angle β is approximately 10 °. The level one with 39 designated gear floor is at the same 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 Manual drive shaft 44, swivel mechanism 43 and bevel pinion 42, and the bevel gear ring 36 mentioned one manually actuatable evacuation device. Furthermore, the Oval-like shape of the gear 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 of the Vertical deviating axis of the motor 1 clearly. The fact that in the vertical line of the motor 1 Gearbox base area does not protrude, this can Elevator drive correspondingly close to a shaft wall 41 be placed because the extension is transverse to the Guide rail level, i.e. the horizontal extension of the Drive between shaft wall and cabin travel profile is correspondingly narrow. Furthermore, one attached below Elevator cabin on the right side of the elevator drive 4 along the cabin guide rails 17 to over start up the motor 1 of 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 gear housing 28 at the interface marked in FIG Transmission housing 28. This Fig.5 shows one for this Gear 2 in terms of strength and torsional rigidity optimal contour of the housing wall. The outer housing contour has a height h which is greater than the width b. The determined using the finite element method The contour of the housing has its course in the example shown four different radii R1-R4, the number merging radii greater or less than four could be. The result is an oval-like one Cross-sectional shape of the housing wall. Furthermore, the Housing wall thickness can be kept relatively small, which is again favorable to the external dimensions and also to the Weight of the transmission 2 affects.

    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 as Disc brake with the appropriate fittings.

    Der Motor 1 kann eine von der gezeigten Ausführung abweichende Grösse und Form aufweisen.The engine 1 can be of the embodiment shown differ in size and shape.
