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.

Die Aufgabe der vorliegenden Erfindung ist es, einen Antrieb zu einer Aufzugsanlage bereitzustellen, welcher geringe äussere Abmessungen aufweist, sicherheitskonform ausgeführt ist und kostengünstig hergestellt werden kann.The object of the present invention is to provide a drive to an elevator installation, which has small external dimensions, is designed in accordance with safety and can be produced inexpensively.

Diese Aufgabe wird durch die Merkmale des unabhängigen Patentanspruches gelöst.This object is solved by the features of the independent claim.

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.

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. That is, the torque transfer from the brake to the support or the housing of the engine or to a next brake by means of pins. Next include the housing of the motor or the support, and the brake, or a fixed part of the brake, a pin hole. The pin is inserted in the pin bore of the motor, or the support.

Fig. 1 zeigt einen Antrieb für eine Aufzugsanlage mit der Hauptcharakteristik der Erfindung. Der Antrieb 1 weist eine oder mehrere Treibscheibenzonen 3 auf und eine Treibscheibenzone 3 umfasst mindestens eine Treibscheibe 2. Die Treibscheibe 2 dient der Aufnahme eines Trag- und Treibmittels 6 welches eine Kabine des Aufzuges mit einem Gegengewicht bzw. einer zweiten Kabine verbindet.
Die Treibscheibe 2 ist beim gezeigten Antrieb 1 in eine Antriebswelle 7 integriert. Ein Motor 4, welcher die Antriebswelle 7 antreibt, ist anschliessend an die Treibscheibe 2 angeordnet. Fig. 1 shows a drive for an elevator installation with the main characteristic of the invention. The drive 1 has one or more drive pulley zones 3 and a drive pulley zone 3 comprises at least one traction sheave 2. The traction sheave 2 serves to receive a carrying and driving means 6 which connects a car of the elevator with a counterweight or a second car.
The traction sheave 2 is integrated in the drive 1 shown in a drive shaft 7. A motor 4, which drives the drive shaft 7, is subsequently arranged on the traction sheave 2.

Erfindungsgemäss ist eine Bremse 5, bzw. ein feststehender Teil der Bremse, wie in Fig. 1, 2 und 3 dargestellt, mittels Bolzen, Stift oder Zapfen 11 mit einem Support 8 verbunden. Die Befestigung der Bremse 5 erfolgt dabei unter Berücksichtigung der Platzverhältnisse und eines optimalen Kraftflusses wahlweise an ein Gehäuse 12 des Motors 4, wie in Fig. 3 dargestellt oder an den Support 8, wie in den Fig. 1 und 2 dargestellt. Die Verwendung von Zapfen 11 bildet eine kostengünstige und platzsparende Ausführung zur Befestigung der Bremse 5.According to the invention, a brake 5, or a fixed part of the brake, as in Fig. 1 . 2 and 3 represented by means of bolts, pin or pin 11 connected to a support 8. The attachment of the brake 5 is carried out taking into account the space available and an optimal power flow either to a housing 12 of the motor 4, as in Fig. 3 shown or to the support 8, as in the Fig. 1 and 2 shown. The use of pin 11 forms a cost-effective and space-saving design for mounting the brake fifth

Vorteilhafterweise ist der Zapfen 11 an dessen einem Ende in eine passende Zapfenbohrung 30 des Supports 8 oder des Gehäuses 12 gesteckt, bzw. das Ende des Zapfens 11 ist im Support 8, bzw. im Gehäuse 12, versenkt angeordnet. 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. Das Andrücken erfolgt in der Regel mittels Federn. 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 pin 11 is inserted at one end into a mating pin hole 30 of the support 8 or the housing 12, or the end of the pin 11 is in the support 8, or in the housing 12, sunk. On a mutual end of the pin 11, the housing of the brake 5, and a fixed part of the brake 5, placed. The pin 11 defines a predetermined distance between the brake 5 and the support 8, and the housing 12. Within the predetermined distance, a brake disc 22 and a brake pressure plate 23 are arranged. The brake disk 22 is non-positively connected to the motor shaft 15 or the drive shaft 7 and rotates with the rotational speed of the motor 4. The brake pressure plate 23 is attracted in the operating position of the drive 1 to the housing of the brake 5, for example. By means of an electromagnet, and is in unlocked the braking position, or pushed to the brake disc 22. The pressing is usually done by means of springs. The brake disk 22 is thereby clamped between the brake pressure plate 23 and a counter housing, such as the support 8, the housing 12 of the engine or another brake 5 ', and thereby brakes the motor shaft 15 or the drive shaft 7. The brake pressure plate 23 is by means of Taper 11 out, so it is secured against twisting. Pin 11 and pin holes 30 can be produced inexpensively. The drive can be produced inexpensively. The illustrated embodiment also takes up little space.
In general, a plurality of pins 11 are mounted distributed over the circumference of the brake 5. The brake 5 is fastened by means of screws, which are preferably guided through a longitudinal bore 24 of the pin 11.

Die Zapfen 11 sowie die Anschlussstellen bei der Bremse 5 und Gehäuse 12 des Motors 4, bzw. Support 8 sind im gesamten betrachtet einfach herstellbar. Dadurch ist ein kostengünstiger und Platz sparender Anbau der Bremse 5 im Antrieb 1 möglich, welcher zudem die Sicherheitsanforderungen, welche an einen formschlüssigen Anbau der Bremse an den Motor gestellt werden, erfüllt.The pins 11 and the connection points in the brake 5 and the housing 12 of the motor 4, or support 8 are in the whole considered easy to manufacture. As a result, a cost-effective and space-saving attachment of the brake 5 in the drive 1 is possible, which also meets the safety requirements, which are placed on a positive mounting the brake to the engine.

In einer besonders sicheren Ausführung sind zwei Bremsmodule 5',5" wie in Fig. 1 und Fig. 2 dargestellt zu einer Bremse 5 zusammengeschalten.
Dadurch ist eine Zwei-Kreis-Bremse ausführbar, welche auch für sicherheitsrelevante Funktionen eingesetzt werden kann.In a particularly safe design are two brake modules 5 ', 5 "as in Fig. 1 and Fig. 2 shown interconnected to a brake 5.
As a result, a two-circuit brake can be executed, which can also be used for safety-related functions.

Wie in den Fig. 1 und 2 dargestellt besteht der Antrieb 1 in einer bevorzugten Ausführung aus zwei voneinander beabstandeten Treibzonen 3, wobei eine Treibzone 3, ein oder mehrere Treibscheiben 2 beinhalten kann. Der Motor 4 und /oder die Bremse 5 sind ausserhalb der beiden Treibzonen 3 angeordnet, und ein Hauptlager 25 ist zwischen den beiden Treibzonen 3 angeordnet, so dass eine Hauptstützkraft der, durch die Trag- und Treibriemen 6 erzeugten, Tragkraft, im wesentlichen, mittels dem Hauptlager 25 in eine Tragstruktur eingeleitet wird.
Damit ist eine direkte und optimale Einleitung der Tragkräfte des Antriebes 1 in eine Tragstruktur ermöglicht. Der Antrieb kann dadurch kompakt gebaut und kostengünstig ausgeführt werden.As in the Fig. 1 and 2 the drive 1 consists in a preferred embodiment of two spaced apart blowing zones 3, wherein a blowing zone 3, one or more traction sheaves 2 may include. The motor 4 and / or the brake 5 are arranged outside the two blowing zones 3, and a main bearing 25 is arranged between the two blowing zones 3, so that a main supporting force of, generated by the support and drive belt 6, carrying capacity, essentially, means the main bearing 25 is introduced into a support structure.
For a direct and optimal introduction of the load capacity of the drive 1 in a support structure is possible. The drive can be made compact and inexpensive.

Besonders vorteilhaft ist die Verwendung von Riemen als Trag- und Treibmittel 6. Trag- und Treibriemen 6 erlauben die Verwendung von kleinen Treibscheibendurchmessern. Dadurch kann ein Antrieb 1 mit entsprechend hohen Drehzahlen und geringen Drehmomenten verwendet werden, was wiederum den Einsatz von Antrieben mit geringen Abmessungen und die Verwendung marktüblicher und entsprechend kostengünstiger Bremsen erlaubt.Particularly advantageous is the use of belts as carrying and propellant 6. Trag- and drive belt 6 allow the use of small pulley diameters. As a result, a drive 1 with correspondingly high speeds and low torques can be used, which in turn allows the use of drives with small dimensions and the use of commercially available and correspondingly cost-effective brakes.

Die Riemen sind dabei entsprechend der Ausführung der Treibscheibe 2 flach, das heisst glatt, oder sie weisen eine Längsprofilierung, beispielsweise in der Form von Keilrippen auf oder sie weisen ein Querprofil, beispielsweise eine Zahnform auf.The belts are flat according to the design of the traction sheave 2, that is smooth, or they have a longitudinal profiling, for example in the form of V-ribs or they have a transverse profile, for example a tooth shape.

In den gezeigten Beispielen der Fig. 1 und Fig. 2 sind Motorwelle 15, Antriebswelle 7 und Treibscheibe 2 einstückig ausgeführt. Alternativ können lediglich die Motorwelle 15 und die Antriebswelle 7 einstückig ausgeführt sein, oder die Antriebswelle 7 und die Treibscheibe 2 sind aus einem Stück hergestellt. Auch die Herstellung als einzelne separate Teile ist selbstverständlich möglich. Die Wahl der geeigneten Ausführungsform erfolgt nach Wahl des Herstellers.In the examples shown the Fig. 1 and Fig. 2 Motor shaft 15, drive shaft 7 and traction sheave 2 are made in one piece. Alternatively, only the motor shaft 15 and the drive shaft 7 may be made in one piece, or the drive shaft 7 and the traction sheave 2 are made in one piece. The production as individual separate parts is of course possible. The choice of suitable embodiment is made at the choice of the manufacturer.

Die Einleitung einer Stützkraft mittels einer Motorseitig angebrachten Stütze 28 entlastet im dargestellten Beispiel die Bremse 5 von Stützkräften. Die Zapfen 11, bzw. der Bremsanbau wird dadurch nur durch die bremseigenen Kräfte - Bremsmoment und Anpresskraft - belastet.The initiation of a support force by means of a motor-mounted support 28 relieved in the example shown, the brake 5 of supporting forces. The pin 11, or the brake attachment is characterized only by the brake forces - braking torque and contact force - charged.

Die dargestellten Ausführungsformen und Verfahren sind Beispiele. So kann beispielsweise die Bremse 5 auch am motorseitigen Ende der Antriebswelle, beispielsweise ausserhalb der Stütze 28, angeordnet sein.The illustrated embodiments and methods are examples. For example, the brake 5 can also be arranged on the motor-side end of the drive shaft, for example, outside the support 28.
