Palettenband und Seitenschilder gebildete Raum für den Antrieb genutzt werden kann. Bei dieser Bauweise kann ein handelsüblicher und kostengünstiger Motor verwendet werden. Die Betriebsbremse wirkt direkt auf die Getriebeeingangswelle und kann daher klein bzw. kleiner dimensioniert werden. Motor und Bremse sind für Unterhalt und Wartung gut zugänglich. Der Motor treibt mittels Riemen, Kette, Band oder Seil die schnelldrehende Getriebeeingangswelle eines Axialgetriebes an. Das Gehäuse des Getriebes dreht sich und ist einenends mit der Hohlwelle verbunden, wobei am einen Ende der Hohlwelle ein Kettenrad angeordnet ist.

The housing of the transmission rotates and is connected at one end to the hollow shaft, wherein at one end of the hollow shaft, a sprocket is arranged. The output shaft of the axial gear is connected by means of a torque arm with the side plate and / or framework of the deflection of the escalator and the moving walk.

As shown in FIG. 5, the two transmission output shafts 22, 26 are mechanically coupled or connected, thereby eliminating the torque supports. For the drive 2.1, the further reference numerals are introduced: first hollow shaft 8.1, transmission input shaft 11.1, housing 25.1, first pulley 9.1, second pulley 12.1 and second brake 13.1.

Fig. 6 zeigt einen Antrieb 2 ohne zweite Hohlwelle 14. Das Gehäuse 7.1 übernimmt die Funktion der Hohlwelle 14 und schließt direkt und formschlüssig an das zweite Kettenrad 5.1 an. Dadurch kann ein zusätzlicher Bauteil gespart werden. Diese Ausführungsvariante ermöglicht eine Fixierung zur einen Seite und eine variable Ausführung bzw. veränderliche Länge bzw. Fahrtreppenbreite machbar mittels der ersten Hohlwelle 8 . Weiters ist das Axialgetriebe 7 somit ortsbestimmt und kann ohne weiteres die Umdrehungen des Gehäuses 7.1 an das zweite Kettenrad 5.1 weitergeben.6 shows a drive 2 without second hollow shaft 14. The housing 7.1 assumes the function of the hollow shaft 14 and connects directly and positively to the second sprocket 5.1. This can save an additional component. This embodiment variant makes possible a fixation on one side and a variable execution or variable length or escalator width feasible by means of the first hollow shaft 8. Furthermore, the axial gear 7 is thus localized and can readily pass the turns of the housing 7.1 to the second sprocket 5.1.

Fig. 7 zeigt eine Ausführungsvariante mit zwei Antrieben 2, 2.1 ohne Hohlwellen 8, 8.1. Die Gehäuse 7.1 und 25.1 schliessen direkt an den Kettenrädern 5 und 5.1 an und sind formschlüssig mit den Kettenrädern 5 und 5.1 verbunden und übertragen die Drehbewegung. Die Gehäuse 7.1, 25.1 übernehmen die Funktion der Hohlwellen 8, 8.1. Die beiden Axialgetriebe 7 und 25 ergeben die benötigte Fahrtreppenbreite und erleichtern den Zusammenbau durch weniger Einzelteile und Verbindungsteile. Das Axialgetriebe 7 stützt sich unmittelbar auf das Axialgetriebe 25 ab. Die beiden Gehäuse 7.1 und 25.1 liegen aneinander und drehen im Gleichtakt. Die mechanische Kopplung der beiden Getriebeausgangswellen 22 und 26 ist weiterhin gegeben. Die Drehmomentstützenfunktion ist weiterhin festgelegt, wobei die beiden Getriebeausgangswellen 22 und 26 still stehen.Fig. 7 shows a variant with two drives 2, 2.1 without hollow shafts 8, 8.1. The housing 7.1 and 25.1 connect directly to the sprockets 5 and 5.1 and are positively connected to the sprockets 5 and 5.1 and transmit the rotational movement. The housing 7.1, 25.1 take over the function of the hollow shafts 8, 8.1. The two axial gear 7 and 25 provide the required escalator width and facilitate assembly by fewer items and connectors. The axial gear 7 is supported directly on the axial gear 25. The two housings 7.1 and 25.1 abut each other and rotate in unison. The mechanical coupling of the two transmission output shafts 22 and 26 is still given. The torque arm function is still fixed, with the two transmission output shafts 22 and 26 stationary.

Fig. 8 zeigt einen Antrieb ohne Hohlwellen 8, 14. Das Gehäuse 7.1 übernimmt die Funktion der Hohlwellen 8, 14 und treibt beide Kettenräder 5 und 5.1 direkt an, wobei Getriebe 7 und Gehäuse 7.1 die komplette Breite einnimmt. Der somit entstandene Rohrabtrieb ist kompakt, simpel zu montieren, leicht, mühelos zu manipulieren, raumsparend sowie kostengünstig zu fertigen.Fig. 8 shows a drive without hollow shafts 8, 14. The housing 7.1 assumes the function of the hollow shafts 8, 14 and drives both sprockets 5 and 5.1 directly, with gear 7 and 7.1 housing occupies the entire width. The resulting tube drive is compact, easy to assemble, lightweight, effortless to manipulate, space-saving and cost-effective to manufacture.
