Abstract (en)

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.

Abstract (de)

An der Unterseite einer Fahrtreppenstufe ist je Seite ein Träger angeordnet, wobei am oberen Trägerende eine erste Befestigung für eine Transportkette und am unteren Trägerende eine zweite Befestigung (6) für eine Laufrolle vorgesehen ist. Die zweite Befestigung (6) besteht aus einem Ausleger (7) und einem Lagerbolzen (8) mit einer Bohrung (9), die integrierte Bestandteile der Fahrtreppenstufe sind, wobei Fahrtreppenstufe, Ausleger (7), Lagerbolzen (8) und Bohrung (9) in einem Guss hergestellt sind. Weder der Lagerbolzen (8) noch die Bohrung (9) brauchen nachbearbeitet zu werden. Das Lager (11) ist auf den Lagerbolzen (8) aufschiebbar. Um den Arbeitsgang des Gewindeschneidens zu sparen, wird zur Fixierung des Lagers (11) eine Senkfurchschraube (13) verwendet. Die Senkfurchschraube (13) formt plastisch ein exaktes Innengewinde in die Bohrung (9). Beim Festziehen der Schraube (13) presst eine der Schraube (13) unterlegte Scheibe (14) auf einen Innennring (12) des Lagers (11), wodurch das Lager (11) an einer Schulter (10) exakt positioniert und von der Scheibe (14) gehalten ist. <IMAGE>
