Abstract

A method for fitting support rollers (3) to an escalator step has each step formed in one piece with the side support flanges. The one piece construction includes a stub axle on each flange, with stepped profiles onto which the support rollers are fitted via a press fit operation. Each support roller is secured by a self tapping screw (9) into a bore in the stub axle. The fitting is completed by a sprung washer (14) under the head of the screw.

Die Erfindung betrifft eine Einrichtung zur Befestigung einer Laufrolle einer Fahrtreppenstufe oder einer Fahrsteigpalette, wobei ein Laufrollenlager zur Aufnahme der Laufrolle an einem Stufenkörper bzw. Palettenkörper angeordnet ist.The invention relates to a device for fastening a roller of an escalator step or one Moving walk pallet, with a roller bearing for receiving the roller on a step body or pallet body is arranged.

Aus der Schrift WO 95/23758 ist eine Fahrtreppenstufe bekannt geworden mit im Gusskörper integrierten Trägern. Je Stufenseite ist ein Träger angeordnet, wobei am Träger eine Befestigung für die Transportkette und eine Befestigung für die Laufrolle vorgesehen ist. Für die Befestigung der Laufrolle ist ein im Träger eingegossener Bolzen vorgesehen, der als Lagersitz für die Laufrolle dient.From the document WO 95/23758 is an escalator step became known with supports integrated in the cast body. Each A support is arranged on the step side, with a support on the support Attachment for the transport chain and an attachment for the roller is provided. For attaching the The roller is a bolt cast into the carrier provided that serves as a bearing seat for the roller.

Ein Nachteil der bekannten Einrichtung liegt darin, dass die Herstellung der Fahrtreppenstufe bzw. der Fahrtsteigpalette wegen des Eingiessens der Lagerbolzen kompliziert und teuer ist.A disadvantage of the known device is that the manufacture of the escalator step or Walkway pallet due to the casting of the bearing bolts is complicated and expensive.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Fahrtreppenstufe bzw. eine Fahrsteigpalette vorzuschlagen, die rationell und kostenoptimiert fertigbar ist. The invention seeks to remedy this. The invention, as characterized in claim 1, solves the problem to avoid the disadvantages of the known device and an escalator step or a moving walk pallet propose that can be produced efficiently and cost-effectively is.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass der Herstellungsvorgang der Stufe bzw. der Palette vereinfacht wird, weil keine Einlegeteile mehr notwendig sind. Ausserdem wird die Herstellung der Gussform bzw. Pressform vereinfacht. Dank der vorgefertigten und mit der Stufe bzw. Palette in einem Stück herstellbaren Befestigung für die Laufrolle werden die Rollenmontage und die Mittel dazu auch vereinfacht. Durch die Vereinfachung des Herstellungsvorganges, der Gussform bzw. Pressform sowie der Montage der Laufrolle sind gesamthaft wesentliche Kosteneinsparungen möglich. Ausserdem können Ersatzrollen leicht und schnell ausgetauscht werden.The advantages achieved by the invention are in essential to see that the manufacturing process the level or pallet is simplified because none Inserts are more necessary. In addition, the Manufacture of the mold or press mold simplified. thanks the prefabricated and with the step or pallet in one Piece of attachable for the roller the roller assembly and the means to do so also simplified. By simplifying the manufacturing process, the Mold or press mold and the assembly of the roller overall significant cost savings are possible. In addition, replacement rolls can be easily and quickly be replaced.

Im folgenden wird die Erfindung anhand von ein Ausführungsbeispiel darstellenden Zeichnungen näher erläutert.In the following the invention is based on a Exemplary embodiment drawings closer explained.

In den Fig. 1 bis 3 ist mit 1 eine Fahrtreppenstufe bezeichnet, die im wesentlichen aus einem beispielsweise aus Aluminium oder Kunststoff gefertigten Stufenkörper 2 und aus Befestigungen für Laufrollen 3 mit Laufflächen 3.1 besteht. Fahrsteigpaletten haben einen vergleichbaren Aufbau. Im weiteren Beschreibungsverlauf wird der Einfachheit wegen lediglich auf eine Fahrtreppenstufe Bezug genommen, die Ausführungen gelten aber ebenso für eine Fahrsteigpalette. An der Unterseite des Stufenkörpers 2 weist der Stufenkörper 2 je Seite einen Träger 4 auf, wobei am oberen Trägerende eine erste Befestigung 5 für eine nicht dargestellte Transportkette und am unteren Trägerende eine zweite Befestigung 6 für die auch Schlepprolle genannte Laufrolle 3 vorgesehen sind.1 to 3, 1 is an escalator step referred to, consisting essentially of an example Step body made of aluminum or plastic 2 and from fastenings for rollers 3 with treads 3.1 consists. Moving walk pallets have a comparable one Construction. In the further course of the description, the Simplicity because of only one escalator step taken, but the explanations also apply to one Moving walk pallet. On the underside of the step body 2 the step body 2 has a carrier 4 on each side, wherein at the upper end of the beam a first attachment 5 for one not shown transport chain and at the lower end of the beam a second attachment 6 for the trailing roller mentioned roller 3 are provided.

Fig. 3 zeigt einen in Fig. 1 mit A bezeichneten Ausschnitt der zweiten, als Fortsatz des Stufenkörpers 2 ausgebildeten Befestigung 6, bestehend aus einem Ausleger 7 und einem Lagerbolzen 8 mit einer Bohrung 9, wobei Stufenkörper 2, Träger 4, erste Befestigung 5, Ausleger 7, Lagerbolzen 8 und Bohrung 9 aus einem Stück gefertigt sind. Der mit einer Schulter 10 versehene Lagerbolzen 8 kann für ein einen Innenring 12 und einen Aussenring 15 aufweisendes Lager 11 der Laufrolle 3 gefertigt werden. Weder der Lagerbolzen 8 noch die Bohrung 9 brauchen nachbearbeitet zu werden. Das Lager 11 ist auf den Lagerbolzen 8 aufschiebbar, wobei der Innenring 12 des Lagers 11 an der Schulter 10 ansteht. Um den Arbeitsgang des Gewindeschneidens zu sparen, wird zur Fixierung des Lagers 11 eine als Furchschraube ausgebildete Schraube 13 verwendet. Die Furchschraube 13 formt plastisch ein exaktes Innengewinde in die Bohrung 9. Beim Festziehen der Schraube 13 presst eine der Schraube 13 unterlegte Scheibe 14 mit konzentrischer Wellenform auf den Innenring 12 des Lagers 11, wodurch das Lager 11 an der Schulter 10 exakt positioniert und von der Scheibe 14 gehalten ist.FIG. 3 shows a section designated by A in FIG. 1 the second, designed as an extension of the step body 2 Attachment 6, consisting of a boom 7 and a Bearing pin 8 with a bore 9, step body 2, Carrier 4, first attachment 5, bracket 7, bearing pin 8 and hole 9 are made in one piece. The one Shoulder 10 provided bearing pin 8 can for a Inner ring 12 and bearing 11 having an outer ring 15 the roller 3 are manufactured. Neither the bearing pin 8 the hole 9 still need to be reworked. The Bearing 11 can be pushed onto the bearing pin 8, the Inner ring 12 of the bearing 11 is applied to the shoulder 10. Around Saving the threading operation becomes Fixation of the bearing 11 designed as a self-tapping screw Screw 13 used. The self-tapping screw 13 forms plastically an exact internal thread in the hole 9. When tightening the screw 13 presses one underlying the screw 13 Disc 14 with a concentric waveform on the inner ring 12 of the bearing 11, whereby the bearing 11 on the shoulder 10 is positioned exactly and held by the disk 14.
