- the interfering edge of the car covered by the guideway is only a very small part and the counterweight is not at all in the area of the drive.
- a collision problem with incorrectly mounted or defective parts on the drive, cab or counterweight does not exist.
- the flying bearing used there combines the gain in space with the problems of the greatly increased bending load and the associated safety risk at the journal.

- the brake which is preferably arranged within the traction sheave (4) and executed as an inner shoe brake, can provide their holding forces regardless of the operability of the drive belt (1).
- the distance "B" can be reduced to a small degree or omitted entirely, provided that the contact between the drive belt (1) and support means (3) does not set a state that presses the support means (3) in the traction sheave and thus the adhesion conditions between Traction sheave (4) and support means (3) are changed in a meaningful way or relevant frictional engagement between the support means (3) and the drive belt (1) is formed.

See also FIG. 11 Distance "x".
- FIG. 5 shows a further embodiment of a drive, wherein one or more inner belt (22) instead of a drive belt in the undercut region of a traction sheave (4) are introduced.
- This variant has the advantage of a very simple propellant, so that the advantages of a standard belt with the advantage of avoiding broadening of the traction sheave, are connected.
- this solution has the disadvantage that to replace the inner belt (22) the support means (3) from the traction sheave (4) must be lifted.
- FIG. 6 the part of a drive is shown in which a belt (8), which drives the drive belt rollers (2), outside and / or inside is positively or frictionally carried out and at least two encoder discs (7).

This can be done on one side or on two sides. Second optional engine not shown.
- FIG. 8 shows an intermediate drive belt roller (2) over which two drive belts (1) are guided.
- Such an arrangement favors the design of the drive belt (1) by reduced width and prevents bending of the drive belt pulley (2).
- This design can be used in both tensioned and fixed rollers and is not limited to a one-time subdivision. If a two- or multi-part drive belt is used, then a web surface in the traction sheave is advantageously omitted between the belts in order to avoid contact between the drive belts.
- FIG. 9 shows a portion of a drive belt (1), which is designed on one side in multi-V shape, with the associated web portion of the traction sheave (4).
- the compression of the tips in the profile of the drive belt (1) in the region of the web and their extension in the spaces can be seen. Due to the band geometry, there is a difference in the width of the drive belt on the traction sheave and the drive belt pulley, if this is cylindrical, and thus to different voltages. In the cross-sectional contour of the drive belt is a transformation stood. For this reason, it is advantageous to make the drive belt in multiple strands to minimize this effect in the single bands.
- the drive belt rollers are equipped with an outer contour that follows the contour of the traction sheave negative and thus this Effect compensates. It is important to ensure that all circumferential lines on the drive belt (1) have the same length.
- the tape shown can be replaced by another drive element, in particular by a band that is smooth on both sides or with this shape. Also, a wedge-shaped belt whose wedges fit into the interstices of the webs and thus increase the positive engagement without touching or pressing the support means (3) is possible.
- FIG. 10 shows a cross-sectional profile of a web portion of a traction sheave (4), in which the edge is provided with a radius "r", which in particular reduces the wear of the tape at the edge when using a drive belt with eg flat side to the drive slide.
- FIG. 11 shows a schematic partial view of a drive, in which the distances "x" represent the zone in which the also in FIG. 9 described band transformations take place.
- the drive rollers (2) is shown, which may be useful by structural measures or allows a favorable placement of the drive motor (9).

Abstract
Description
Die nachfolgende Erfindung wird am Beispiel eines Aufzugs beschrieben, da sie dort einen wesentlichen Einsatzort findet.The following invention will be described using the example of an elevator, as it finds a significant place of use there.
Um eine Bewegung in das System einzuleiten, finden in Aufzügen bisheriger Bauart verschiedene Antriebe Verwendung. Eine Antriebsart treibt das Tragmittel direkt an. Das bedeutet, dass z.B. Stahlseile oder bandähnliche Tragmittel durch eine Treibscheibe bzw. Treibrolle zwangsweise bewegt werden und somit die Kabine und die anderen Komponenten in ihrer Lage verändert bzw. stabilisiert werden. Der Antrieb einer solchen Treibscheibe erfolgt z.B. mittels eines Getriebes durch einen Elektromotor. Getriebe sind wenig kompakt, schwer und ihr Geräuschpegel ist hoch und vermindert den Fahrkomfort. Ihr Vorteil ist die Verwendbarkeit von Standardmotoren. Bei Ketten- oder Riemenantrieben sind die Übersetzungsmöglichkeiten bei vertretbarem konstruktivem Aufwand stark eingeschränkt, der Einsatz von Standardmotoren (z.B. 2 bzw. 4poliger Asynchronmotor) ist nicht möglich. Beim direkten Antrieb der Treibscheibe (z.B. Gearless) ist im Regelfall ein elektrischer Antrieb direkt in die Treibscheibe integriert. Sie besitzen den Nachteil höchster erforderlicher Drehmomente und daraus resultierend große und teure elektrische Komponenten. Um die Drehzahl zu erhöhen, werden oft Hilfsübersetzungen wie z.B. Flaschenkonstruktionen in der Tragmittelführung eingesetzt. Dies verteuert die Anlage durch mehr Seillänge und zusätzliche Rollen und Befestigungsvorrichtungen. Das hohe Gewicht des Antriebs wirkt nachteilig, da der Antrieb in Einzelteilen nicht sinnvoll vor Ort montiert werden kann. Außerdem ergeben sich bei dieser Konstruktion zwangsläufung große Drehmassen, die schwer zu wuchten sind und somit zu Vibrationen neigen. Zusätzlich beeinflusst deren Trägheit die Energieeffizienz nachteilig. Beim Einsatz von Stahlseilen ergibt sich aus dem erforderlichen Durchmesserverhältnis zwischen Stahlseil und Treibscheibe ein Durchmesser der Treibscheibe, der die oben beschriebenen Nachteile bezüglich Drehzahl und Drehmoment bedingt. Trotz dieser Nachteile besitzt das Stahlseil sehr große Vorzüge. Es ist eine kostengünstige, ausgereifte und unproblematische Konstruktion, welche eine einfache Verschleiß- und Bruchüberwachung zulässt und bei erforderlichen Zusatzrollen Schräglaufwinkel ermöglicht. Die Nachteile der Stahlseile versucht man z.B. mit bandähnlichen Tragmitteln zu vermeiden. Diese bandförmigen Tragmittel, mit vorzugsweise nichtmetallischer Oberfläche, bringen zwar deutliche Verbesserungen des Treibrollendurchmessers und der dadurch vorteilhaften Erhöhung der Antriebsdrehzahl, sind aber im Handling problematisch. Es sind z.B. nur keine bis geringe Schräglaufwinkel und somit nur einfache parallele Umlenkungen möglich und ein weiterer großer Nachteil ist die sehr aufwendige Verschleiß- und Bruchüberwachung der Tragmittelkonstruktion und deren Einlagen sowie die teure Herstellung.To initiate a movement in the system, found in elevators previous design various drives use. One type of drive drives the suspension element directly. This means that, for example steel cables or tape-like suspension means are forcibly moved by a traction sheave or drive roller and thus the cabin and the other components are changed or stabilized in their position. The drive of such a traction sheave is done for example by means of a transmission by an electric motor. Gears are not very compact, heavy and their noise level is high and reduces ride comfort. Their advantage is the usability of standard motors. In the case of chain or belt drives, the possibilities of translation are considerably restricted with reasonable constructive effort; the use of standard motors (
Um die Probleme der niedrigen Drehzahlen für die Antriebsmotoren zu vermeiden, werden verschiedene Lösungen offenbart. In der
In der
Um der Antriebsproblematik für Aufzüge zu entsprechen, bei gleichzeitiger Erfüllung des Anspruchs an niedrigste Kosten sowohl des Antriebs selbst wie auch dessen Folgekosten bei Montage und Konstruktion, bedarf es einer Lösung welche diese Anforderungen zufriedenstellend löst.In order to meet the drive problem for elevators, while meeting the demand for lowest cost both of the drive itself as well as its subsequent costs in assembly and construction, it requires a solution which satisfactorily solves these requirements.
Die erfindungsgemäße Weiterbildung eines Bandantriebs mit seinen Gestaltungsvarianten vermeidet die Nachteile der zuvor aufgeführten Antriebe und stellt eine universell einsetzbare Alternative zu den bisher verwendeten Antrieben dar. Eine Einschränkung bezüglich Förderhöhe und Geschwindigkeit besitzt er nicht. Eine Treibscheibe (4) wird teilweise von einem Tragmittel (3) umschlungen, welches vorzugsweise ein Stahlseil ist. Die Treibscheibe wird durch ein Treibband (1) umschlungen, welches über Rollen läuft und vorzugsweise als endloses Bauteil ausgeführt ist. Diese Rollen, im Weiteren als Treibbandrollen (2) bezeichnet, sind vorzugsweise in reibschlüssigem Kontakt mit dem Treibband (1). Die Außenseite des Treibbandes ist in vorzugsweise reibschlüssigem Kontakt zur Treibscheibe. Wird eine oder mehrere der Treibbandrollen (2) angetrieben, so überträgt sich diese Bewegung auf die Treibscheibe in Form einer Drehbewegung. Die Treibscheibe leitet diese Bewegung an das Tragmittel weiter, dieses wird je nach Drehrichtung von der einen zur anderen Seite verbracht und ermöglicht somit die Bewegung der Kabine und der restlichen Komponenten. In einer Weiterbildung der Erfindung werden die Treibbandrollen mit dem Antriebsmotor (9) durch ein Vorgelege verbunden. Eine vorteilhafte Lösung, vorzugsweise bei Aufzügen mit hohen Kabinengeschwindigkeiten, ist der direkte Antrieb der Treibbandrollen. Eine vorteilhafte Weiterbildung der Erfindung sieht eine direkt mit der Treibscheibe verbundene Bremseinheit vor, welche alle sicherheitsrelevanten Notwendigkeiten für Aufzugsanlagen erfüllt. Diese Bremse wird vorteilhafterweise als Innenbackenbremse in die Treibscheibe integriert. Somit stellen die Treibscheibe mit Bremse und der Antrieb eine voneinander unabhängige Baueinheit dar. Ebenso sind der Antriebsmotor, die Treibbandrollen, das Treibband und andere Bauteile getrennt montier- und austauschbar. Die Nachteile von Kompaktantrieben, wie z.B. bei Gearless, entfallen. Eine Beschreibung, Darstellung oder technische Abhandlung der Bremse, welche in der Treibscheibe eingebracht bzw. mit ihr verbunden ist, findet nicht statt, da sie Stand der Technik ist. Der Einsatz eines umlaufenden Treibbandes, mit Treibrollen die einen kleinen Durchmesser aufweisen, ermöglicht eine Reduzierung der Drehzahl. In Verbindung mit einer indirekten Primärübersetzung, wie in
Bei einer möglichen Ausführung der Erfindung kann das Treibband durch ein anderes Element als einen Multi-V-Riemen ausgeführt werden, dessen Oberflächenform oder Oberflächenbeschaffenheit geeignet ist. Es kann auch vorgesehen werden, dass die Kontur des Querschnitts der Oberfläche der Treibscheibe (4) eben ist. Unabhängig von den oben gewählten Maßnahmen und/oder auch unter Verzicht einer speziellen geometrischen Querschnittsausbildung der Treibscheibe (4) im Bereich oder zumindest in Teilbereichen der Treibbandauflage können die Abstände der Rillen für die Führungen des Treibbandes in der Treibscheibe zur Verminderung oder Vermeidung der Spannungen im Treibbandquerschnitt geringer als im Riemen ausgeführt werden.In one possible embodiment of the invention, the drive belt can be implemented by a different element than a multi-V belt whose surface shape or surface finish is suitable. It can also be provided that the contour of the cross section of the surface of the traction sheave (4) is flat. Regardless of the measures chosen above and / or waiving a special geometric cross-sectional training of the traction sheave (4) in the area or at least in partial areas of the drive belt support, the distances of the grooves for the guides of the drive belt in the traction sheave to reduce or avoid the stresses in the drive belt cross section less than in the belt.
Bei einem Ausführungsbeispiel der Erfindung kann der Antrieb statt einem Treibband (1) einen oder mehrere Außenriemen besitzen, der die Treibscheibe (4) in jenem Bereich umfasst, welcher sich nicht in der Zone befindet, in der das Tragmittel (3) über die Treibscheibe (4) geführt wird. Zwischen mindestens einer der Treibbandrollen (2) und dem Treibband (1) kann statt Reibschluss Formschluss bestehen. Es kann vorgesehen sein, dass bei Formschluß hauptsächlich das gebräuchliche STD Zahnprofil findet.In one embodiment of the invention, instead of a drive belt (1), the drive may have one or more outer belts comprising the traction sheave (4) in that area which is not in the zone in which the suspension means (3) are accessible via the traction sheave (3). 4) is guided. Between at least one of the drive belt rollers (2) and the drive belt (1) can be made instead of frictional locking positive engagement. It can be provided that when form-fitting mainly the common STD Tooth profile finds.
Der Antrieb kann des Weiteren über eine oder mehrere Antriebseinheiten (9) verfügen, die auf eine und/oder mehrere Treibbandrollen (2) wirken, und die Treibbandrollen (2) können verschiedene Durchmesser aufweisen. Auch kann vorgesehen werden, dass die Antriebseinheiten (9), bei elektrischer Ausführung, eine unterschiedliche Poligkeit aufweisen und es sich dabei um asynchrone oder synchrone Standard-Käfigläufermotoren handelt.The drive may further comprise one or more drive units (9) acting on one and / or more drive belt pulleys (2), and the drive belt pulleys (2) may have different diameters. It can also be provided that the drive units (9), in electrical design, have a different polarity and are asynchronous or synchronous standard squirrel-cage motors.
Bei einer Ausführungsform der Erfindung kann/können die Treibscheibe/n einen zusätzlichen Antrieb aufweisen. Die Rillen in der Treibscheibe (4) und/oder die Treibbandoberfläche können so ausgeführt sein, dass das Tragmittel (3) über den Außenumfang der Treibscheibe (4) übersteht und das Treibband (1) vorzugsweise nur das Tragmittel (3) kontaktiert.In one embodiment of the invention, the traction sheave (s) may have an additional drive. The grooves in the traction sheave (4) and / or the drive belt surface may be designed so that the support means (3) projects beyond the outer circumference of the traction sheave (4) and the drive belt (1) preferably only contacts the support means (3).
Es kann vorgesehen werden, dass die Treibscheibe (4) bzw. Treibrolle Trägerscheibe bzw Trägerrolle ausgeführt ist. Das Tragmittel (3) kann auch so ausgeführt sein, dass es hauptsächlich nur ein Bewegungsmittel ist.It can be provided that the traction sheave (4) or drive roller carrier disk or carrier roller is executed. The support means (3) can also be designed so that it is mainly only a means of movement.
Die erfindungsgemäße Weiterbildung vereint, bei erheblicher Kostenreduktion, viele Vorteile bisheriger Antriebe und vermeidet deren Nachteile.The development of the invention combines, with considerable cost reduction, many advantages of previous drives and avoids their disadvantages.
