Description
Die Erfindung betrifft einen Antrieb für eine Aufzugsanlage gemäss Oberbegriff des unabhängigen Patentanspruches.The invention relates to a drive for an elevator installation according to the preamble of the independent claim.
Eine Aufzugsanlage besteht aus einer Kabine zur Aufnahme von Transportgut oder Personen und einem Gegengewicht, bzw. einer zweiten Kabine, welche mittels einem Trag- und Treibmittel über einen Antrieb miteinander verbunden sind. Der Antrieb der Aufzugsanlage bezweckt dabei das Treiben der Treib- und Tragmittel und damit ein wechselseitiges Heben und Senken von Kabine und Gegengewicht.An elevator system consists of a cabin for receiving cargo or persons and a counterweight, or a second cabin, which are connected to each other by means of a support and propellant means of a drive. The drive of the elevator system aims to drive the driving and suspension means and thus a reciprocal lifting and lowering of the car and counterweight.
Der Antrieb besteht aus den Hauptkomponenten Treibscheibe, Motor und Bremse. Die Treibscheibe nimmt die Trag- und Treibmittel auf und überträgt mittels Form- oder Reibschluss Treibkräfte auf die Trag- und Treibmittel. Der Motor treibt seinerseits die Treibscheibe und die Bremse bremst die Treibscheibe.
Motor, Bremse und Treibscheibe sind dementsprechend Kräfte- und Momentenwirksam miteinander verbunden.The drive consists of the main components traction sheave, motor and brake. The traction sheave receives the carrying and blowing agent and transmits by means of positive or frictional connection driving forces on the carrying and blowing agents. The engine in turn drives the traction sheave and the brake brakes the traction sheave.
Motor, brake and traction sheave are accordingly connected to each other in terms of force and torque.
Aus EP 1'400'477 ist ein Antrieb zu einem Aufzug bekannt bei welchem ein Motor mittels einer Antriebswelle Treibscheiben treibt und die Treibscheiben von einer Bremse gebremst werden. Die Treibscheiben sind dabei, in einer bevorzugten Ausführungsform, zwischen dem Motor und der Bremseinheit angeordnet. Die Treibscheiben treiben Flachriemen. Dies erlaubt die Verwendung von kleinen Treibscheibendurchmessern. Der Antrieb kann dadurch klein und kompakt gebaut werden.
Die geringen Abmessungen und die kompakte Bauweise dieses Antriebes ergeben neue Herausforderungen. Brems- und Motorgehäuse müssen Kräfte- und Momentenwirksam miteinander verbunden sein. Die Verbindung zur Bremse muss sicherheitskonform, das heisst zumindest Formschlüssig ausgeführt sein. Dabei sollen die kleinen Abmessungen beibehalten werden.From EP 1'400'477 a drive to an elevator is known in which a motor drives traction sheaves by means of a drive shaft and the traction sheaves are braked by a brake. The traction sheaves are arranged, in a preferred embodiment, between the engine and the brake unit. The traction sheaves drive flat belts. This allows the use of small pulley diameters. The drive can be made small and compact.
The small dimensions and compact design of this drive result in new challenges. Brake and motor housings must be connected to each other in terms of force and torque. The connection to the brake must be safety-compliant, ie at least form-fitting. The small dimensions should be maintained.

Der Support bildet die gemeinsame Tragstruktur des Antriebes an dem, je nach Ausführungsart, Teile des Antriebes angeordnet sind. Er ermöglicht die Befestigung des Antriebes im Gebäude. Der Support kann dabei ein integraler Bestandteil des Motors oder der Bremse sein oder er kann ein Gehäuse sein, welches beispielsweise Lagerstellen des Antriebs aufnimmt oder die Treibscheiben umschliesst.The invention relates to a drive for an elevator system, which drives a car and a counterweight via a support and propellant and the drive includes a traction sheave, which is driven by a drive shaft of a motor and braked by a brake, wherein drive shaft, motor and brake assembled with a support to a unit. The support forms the common support structure of the drive to which, depending on the embodiment, parts of the drive are arranged. It allows the attachment of the drive in the building. The support can be an integral part of the engine or the brake or it can be a housing which receives, for example bearings of the drive or surrounds the traction sheaves.
Erfindungsgemäss ist die Bremse mittels Zapfen mit dem Gehäuse des Motors oder mit dem Support oder mit einer weiteren Bremse verbunden. D.h. die Momentenübertragung von der Bremse zum Support oder zum Gehäuse des Motors oder zu einer nächsten Bremse erfolgt mittels Zapfen. Weiter enthalten dabei das Gehäuse des Motors oder der Support, und die Bremse, bzw. ein feststehender Teil der Bremse, eine Zapfenbohrung. Der Zapfen ist in die Zapfenbohrung des Motors, bzw. des Supports eingefügt. Die Bremse ist mittels der bremsseitigen Zapfenbohrung auf den entsprechenden Zapfen befestigt. Die Bremse ist damit Drehmomentenfest, bzw. Formschlüssig mit dem Motor bzw. dem Support verbunden.
Die Zapfen sowie die Anschlussstellen bei Bremse und Gehäuse, bzw. Support sind einfach herstellbar. Dadurch ist eine kostengünstige und platzsparende Verbindung der Bremse im Antrieb möglich, welche zudem die Sicherheitsanforderungen erfüllt, welche an eine formschlüssige Verbindung gestellt werden.According to the invention, the brake is connected by means of pins with the housing of the motor or with the support or with another brake.

Auf ein gegenseitiges Ende des Zapfens 11 ist das Gehäuse der Bremse 5, bzw. ein feststehender Teil der Bremse 5, aufgesetzt. Der Zapfen 11 definiert eine vorbestimmte Distanz zwischen der Bremse 5 und dem Support 8, bzw. dem Gehäuse 12. Innerhalb der vorbestimmten Distanz sind eine Bremsscheibe 22 und eine Bremsdruckplatte 23 angeordnet. Die Bremsscheibe 22 ist kraftschlüssig mit der Motorwelle 15 oder der Antriebswelle 7 verbunden und dreht sich mit der Drehgeschwindigkeit des Motors 4. Die Bremsdruckplatte 23 ist in der Betriebsstellung des Antriebes 1 zum Gehäuse der Bremse 5 hingezogen, bspw. mittels eines Elektromagneten, und wird in der Bremsstellung freigeschalten, bzw. an die Bremsscheibe 22 gedrückt.

Die Bremsscheibe 22 ist dadurch zwischen der Bremsdruckplatte 23 und einem Gegengehäuse, wie bspw. dem Support 8, dem Gehäuse 12 des Motors oder einer weiteren Bremse 5', festgeklemmt und bremst dadurch die Motorwelle 15 oder die Antriebswelle 7. Die Bremsdruckplatte 23 ist mittels des Zapfens 11 geführt, womit sie gegen Verdrehen gesichert ist. Zapfen 11 und Zapfenbohrungen 30 lassen sich kostengünstig herstellen. Der Antrieb kann dadurch kostengünstig hergestellt werden. Die dargestellte Ausführung beansprucht zudem wenig Platz.
In der Regel sind mehrere Zapfen 11 über den Umfang der Bremse 5 verteilt angebracht. Die Bremse 5 wird mittels Schrauben, welche vorzugsweise durch eine Längsbohrung 24 des Zapfens 11 geführt sind, befestigt.Advantageously, the
