Description

Die Erfindung betrifft einen Antrieb für Rolltreppen oder Rollsteige, der innerhalb des Stufen- oder Palettenbandes angeordnet ist, mit einem Verteilergetriebe mit zwei Abtriebswellen, nämlich einer für den Handlauf und einer für das Stufen- oder Palettenband, wobei jede Abtriebswelle mit jeweils einem Antriebsrad zum Antreiben derselben versehen ist, sowie mit einer zwischen den Antriebswellen angeordneten Antriebseinheit für das Verteilergetriebe, welche wenigstens einen Elektromotor mit Planetengetriebe aufweist.The invention relates to a drive for escalators or Moving sidewalks within the step or pallet belt is arranged with a transfer case with two output shafts, namely one for the handrail and one for the step or pallet belt, each output shaft each with a drive wheel for driving the same is provided, as well as with one between the drive shafts arranged drive unit for the transfer case, which has at least one electric motor with planetary gear having.

Ein solcher Antrieb ist aus DE 35 26 905 C2 der Anmelderin bekannt. Dieser bekannte Antrieb weist ein Verteilergetriebe mit zwei Abtriebswellen auf, an dem ein Motor-Getriebe-Modul angeordnet ist, das über ein mehrstufiges Planetengetriebe ein fest im Verteilergetriebe eingebautes Zahnrad antreibt, das in Wirkverbindung mit den Zahnrädern der Abtriebswellen für das Stufenband und für den Handlauf steht. Das Antriebszahnrad ist im Gehäuse des Verteilergetriebes gelagert, während das Motor-Getriebe-Modul eine separate Einheit bildet und nach der Montage mit dem Antriebszahnrad in Wirkverbindung steht.Such a drive is from DE 35 26 905 C2 of the applicant known. This known drive has a transfer case with two output shafts on which an engine-transmission module is arranged over a multi-stage Planetary gear is a built-in in the transfer case Gear drives that in operative connection with the gears the output shafts for the step belt and for the Handrail stands. The drive gear is in the housing of the Transfer case mounted while the engine-transmission module forms a separate unit and after assembly is operatively connected to the drive gear.

Aus den gegebenen Wellenabständen der Abtriebswellen bei Rolltreppen oder Rollsteigantrieben und der Gegebenheit, dass das Motor-Getriebe-Modul zwischen den Abtriebswellen angeordnet ist, wird bei einer solchen Bauform nur eine relativ kleine Übersetzung mit den fest im Verteilergetriebe angeordneten Zahnrädern erreicht. Das Verteilergetriebe selbst trägt somit zur Erzielung der erforderlichen Übersetzung nur wenig bei, es ist deshalb ein entsprechend aufwendiges Motor-Getriebe-Modul erforderlich, bei dem die notwendige Über- bzw. Untersetzung weitgehend vom Planetengetriebe zur Verfügung gestellt wird. Außerdem ist sowohl die Montage des Verteilergetriebes als auch des Motor-Getriebe-Moduls am Verteilergetriebegehäuse relativ aufwendig.From the given shaft spacing of the output shafts Escalators or escalator drives and the circumstances, that the motor-transmission module between the output shafts is arranged, only one in such a design relatively small translation with the fixed in the transfer case arranged gears reached. The transfer case itself thus contributes to achieving the necessary Translation only a little, so it is appropriate complex motor-transmission module required, where the necessary gear ratio is largely is provided by the planetary gear. Moreover is both the assembly of the transfer case and also the engine-transmission module on the transfer case relatively complex.

Aufgabe der Erfindung ist es, ein gattungsgemäßes Getriebe zu verbessern, um insbesondere eine einfachere Montage erreichen und konstruktiv einfachere und damit kostengünstigere Bauteile verwenden zu können.The object of the invention is a generic transmission to improve, in particular, easier assembly achieve and structurally simpler and therefore cheaper To be able to use components.

Diese Aufgabe wird bei einem Antrieb der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, dass der Elektromotor, das Planetengetriebe und eine mit dem Abtrieb des Planetengetriebes verbundene Antriebsstufe für den direkten Antrieb wenigstens des Antriebsrades der Abtriebswelle für das Stufen- oder Palettenband eine gemeinsame Montageeinheit bilden, die am Verteilergetriebe befestigbar ist. This task is described for a drive of the type mentioned Art solved according to the invention in that the Electric motor, the planetary gear and one with the output of the planetary gear connected drive stage for the direct drive of at least the drive wheel of the output shaft a common one for the step or pallet belt Form assembly unit on the transfer case is attachable.

Anders als beim Stand der Technik gemäß DE 35 26 905 C2 ist somit der zentrale Antrieb für das Verteilergetriebe nicht mehr im Verteilergetriebe selbst angeordnet, sondern als mit dem Planetengetriebe verbundene Antriebsstufe ausgebildet, die als gemeinsame Montageeinheit mit dem Elektromotor und dem Planetengetriebe ausgebildet ist. Diese Antriebsstufe kann dabei als Untersetzung ausgebildet sein, so dass im Planetengetriebe selbst Untersetzung eingespart werden kann, was das Planetengetriebe wesentlich weniger aufwendig macht. Außerdem ist die Montage des Verteilergetriebes selbst wesentlich einfacher, da es die eigentlichen Antriebselemente nicht enthält. Die Montageeinheit ist ebenfalls einfach zu montieren, da sie lediglich an das Gehäuse des Verteilergetriebes angeflanscht oder in anderer Weise befestigt werden muss.In contrast to the prior art according to DE 35 26 905 C2 is therefore the central drive for the transfer case no longer arranged in the transfer case itself, but instead as a drive stage connected to the planetary gear trained using as a common assembly unit the electric motor and the planetary gear is. This drive stage can be designed as a reduction be so that in the planetary gear itself reduction can be saved what the planetary gear makes much less expensive. In addition, the assembly the transfer case itself much easier, since it does not contain the actual drive elements. The assembly unit is also easy to assemble because they only flanged to the housing of the transfer case or must be attached in some other way.

Nach einer ersten Ausgestaltung ist vorgesehen, dass die Antriebsräder beider Abtriebswellen jeweils als Zahnrad ausgebildet sind und die Antriebsstufe der Montageeinheit beide Zahnräder direkt antreibt.According to a first embodiment, it is provided that the Drive wheels of both output shafts each as a gear are trained and the drive stage of the assembly unit drives both gears directly.

Alternativ kann auch vorgesehen sein, dass die Antriebsstufe nur für den direkten Antrieb des als Zahnrad ausgebildeten Antriebsrades der Abtriebswelle für das Stufenoder Palettenband ausgebildet ist und die Abtriebswelle für den Handlauf über eine Antriebskette mit der Abtriebswelle für das Stufen- oder Palettenband verbunden ist.Alternatively, it can also be provided that the drive stage only for the direct drive of the gear train Drive wheel of the output shaft for the step or Pallet belt is formed and the output shaft for the handrail via a drive chain with the output shaft connected for the step or pallet belt is.

Besonders bevorzugt ist vorgesehen, dass die Antriebsstufe der Montageeinheit als Getriebestufe ausgebildet ist, welche ein mit dem Abtrieb des Planetengetriebes verbundenes Ritzel und wenigstens ein Zwischenrad aufweist. Es ist somit auf einfache Weise möglich, außerhalb des Planetengetriebes, aber in der gemeinsamen Montageeinheit eine zusätzliche Untersetzung unterzubringen, die fest mit dem Planetengetriebe verbunden ist, wodurch im Planetengetriebe selbst Untersetzung eingespart werden kann.It is particularly preferably provided that the drive stage the assembly unit is designed as a gear stage, which is connected to the output of the planetary gear Pinion and at least one idler gear. It is therefore possible in a simple way, outside the planetary gear, but in the common assembly unit to accommodate an additional gear reduction that is fixed is connected to the planetary gear, whereby in the planetary gear even reduction can be saved.

Wenn beide Abtriebswellen mit Antriebszahnrädern ausgerüstet sind, ist dabei selbstverständlich vorgesehen, dass die Getriebestufe zwei Zwischenräder aufweist, die vorteilhaft unterschiedliche Breiten aufweisen können.If both output shafts are equipped with drive gears are, of course, provided that the gear stage has two idler gears that can advantageously have different widths.

Um die Lagerung des oder der Zwischenräder in der Montageeinheit möglichst einfach zu ermöglichen, ist vorteilhaft vorgesehen, dass das wenigstens eine Zwischenrad auf einem Zapfen gelagert ist, der fest mit dem Gehäuse der Montageeinheit verbunden ist.To the storage of the idler gear (s) in the assembly unit To make it as simple as possible is advantageous provided that the at least one idler gear a pin is mounted, which is fixed to the housing of the Assembly unit is connected.

In an sich bekannter Weise kann weiterhin vorteilhaft vorgesehen sein, dass zwei oder mehrere Montageeinheiten parallel zu den Abtriebswellen an dem Verteilergetriebe angeordnet sind. Diese Ausgestaltung ist für sich betrachtet beispielsweise aus DE 35 26 905 C2 bekannt, worauf diesbezüglich Bezug genommen wird.In a manner known per se can also be advantageous be provided that two or more assembly units parallel to the output shafts on the transfer case are arranged. This configuration is considered on its own known for example from DE 35 26 905 C2, what is referred to in this regard.

Die Abtriebswellen 12 und 13 sind Bestandteil eines Verteilergetriebes, dessen Gehäuse mit 14 bezeichnet ist und in dem die Abtriebswellen 12, 13 gelagert sind. Weiterer Bestandteil des Verteilergetriebes ist jeweils ein drehfest mit der zugehörigen Abtriebswelle 12, 13 verbundenes Antriebszahnrad 10 bzw. 11.The output shafts 12 and 13 are part of a transfer case, whose housing is designated 14 and in which the output shafts 12, 13 are mounted. Another One component of the transfer case is a non-rotatable one connected to the associated output shaft 12, 13 Drive gear 10 or 11.

Zum Antrieb dieses Verteilergetriebes ist eine allgemein mit 3 bezeichnete Montageeinheit vorgesehen, die einen Elektromotor 1 mit Planetengetriebe 2, sowie eine mit dem Abtrieb des Planetengetriebes 2 verbundene, beim Ausführungsbeispiel als Getriebestufe ausgebildete Antriebsstufe aufweist. Diese Getriebestufe umfasst beim Ausführungsbeispiel ein mit der Abtriebswelle des Planetengetriebes 2 verbundenes Ritzel 9 sowie zwei Zwischenräder 7 und 8, wobei im Montagezustand das Zwischenrad 7 mit dem Antriebszahnrad 10 der Abtriebswelle 12 und das Zwischenrad 8 mit dem Antriebszahnrad 11 der Abtriebswelle 13 kämmt. Die Zwischenräder 7, 8 sind jeweils drehbar auf einem Zapfen 5 bzw. 6 gelagert, die fest an einem Gehäuse 4 der gemeinsamen Montageeinheit 3 angeordnet sind.One is general for driving this transfer case provided with 3 assembly unit provided a Electric motor 1 with planetary gear 2, and one with the Output of the planetary gear 2 connected, in the embodiment Drive stage designed as a gear stage having. In the exemplary embodiment, this gear stage comprises one with the output shaft of the planetary gear 2 connected pinion 9 and two intermediate wheels 7 and 8, wherein the intermediate gear 7 with the Drive gear 10 of the output shaft 12 and the idler gear 8 with the drive gear 11 of the output shaft 13 combs. The intermediate wheels 7, 8 are each rotatable a pin 5 or 6 mounted, which is fixed to a housing 4 of the common assembly unit 3 are arranged.

Fig. 2 zeigt die komplette Montageeinheit 3 vor der Montage am Gehäuse 14 des Verteilergetriebes. Diese gemeinsame Montageeinheit 3 kann auf einfache Weise am Gehäuse 14 des Verteilergetriebes angeflanscht werden, was mit dem Bezugszeichen 15 angedeutet ist.Fig. 2 shows the complete assembly unit 3 before assembly on the housing 14 of the transfer case. This common Assembly unit 3 can be easily attached to the housing 14 of the transfer case are flanged, what with the reference numeral 15 is indicated.

Die Über- bzw. Untersetzung vom Elektromotor 1 erfolgt somit zunächst über das Planetengetriebe 2 und dann über die zusätzliche Getriebestufe 9, 7, 8 zu den Antriebszahnrädern 10 bzw. 11 der Abtriebswellen 12, 13.The ratio of the electric motor 1 takes place thus first over the planetary gear 2 and then over the additional gear stage 9, 7, 8 to the drive gears 10 and 11 of the output shafts 12, 13.

Alternativ kann auch vorgesehen sein, dass die Abtriebswelle 13 nicht über ein Antriebszahnrad 11 und das Zwischenrad 8 angetrieben wird, sondern über einen Kettentrieb oder dgl. von der Abtriebswelle 12, wie dies für sich betrachtet beispielsweise aus DE 35 26 905 C2 bekannt ist.Alternatively, it can also be provided that the output shaft 13 does not have a drive gear 11 and the intermediate gear 8 is driven, but via a chain drive or the like.
