Railway applications - Axleboxes - Part 2: Deployment Procedure

Edition date: 2025-12-10
In Force
Available languages: German, French, English
Summary: This document is a part of a package of standards: EN 12080, EN 12081, EN 12082-1 and EN 12082-2. This document specifies the principles and methods for deployment of the system of axlebox rolling bearing(s), housing, seal(s) and grease, required for reliable operation of trains on European networks. It covers the conformity assessment with respect to design requirements on the rolling bearing(s) according EN 12080 and grease according EN 12081 as well as the performance of (rig) tests according to EN 12082-1. This document is historically developed for outboard applications with rotating inner rings, but can be used for vehicles with inboard bearing arrangements with rotation inner rings. The present document describes the complete deployment procedure for new axleboxes and it specifies the necessary type and extent of testing. For certain cases and based on a documented risk assessment, a reduced deployment procedure is described. This document only applies to axleboxes equipped with rolling bearings and greases according to EN 12080 and EN 12081. It is not within the scope of EN 12082-2 to specify the technical details of the testing procedures, these are covered by EN 12082-1. It is not within the scope of EN 12082-2 to define the validation procedure of box housings, sleeves or coves from a structural point of view. The relevance of these parts in the scope of this document is limited to the interaction with the axle box rolling bearing with respect to the required service.

Dieses Dokument ist Teil eines Normungspakets: EN 12080, EN 12081, EN 12082 1 und EN 12082 2. Dieses Dokument legt die Grundlagen und Verfahren für die Inverkehrbringung der Baugruppe Radsatzlager, bestehend aus Wälzlager(n), Lagergehäuse, Dichtung(en) und Schmierfett, fest, die für den zuverlässigen Betrieb von Zügen auf den europäischen Schienennetzen erforderlich sind. Es behandelt die Konformitätsbewertung in Hinsicht auf die Ausführungsanforderungen an das/die Wälzlager nach EN 12080 und Schmierfett nach EN 12081 sowie die Leistung von Prüfungen (auf dem Prüfstand) nach EN 12082 1. Dieses Dokument wurde ursprünglich für Außenlagerungen mit rotierenden Innenringen entwickelt, kann jedoch auch für Fahrzeuge mit Innenlageranordnungen mit rotierenden Innenringen verwendet werden. Dieses Dokument beschreibt den gesamten Inverkehrbringungsprozess für neue Radsatzlager und es legt den erforderlichen Typ und den Umfang der Prüfung fest. Für bestimmte Fälle und beruhend auf einer dokumentierten Risikobeurteilung wird ein reduzierter Inverkehrbringungsprozess beschrieben. Dieses Dokument ist nur anwendbar für Radsatzlager, die mit Wälzlagern und Schmierfetten nach EN 12080 und EN 12081 ausgestattet sind. Es liegt nicht im Anwendungsbereich von EN 12082 2, die technischen Einzelheiten der Prüfverfahren festzulegen; diese sind in der EN 12082 1 enthalten. Die Festlegung des Validierungsverfahrens von Lagergehäusen, Hülsen oder Deckel aus struktureller Sicht fällt nicht in den Anwendungsbereich von EN 12082 2. Die Bedeutung dieser Teile im Anwendungsbereich dieses Dokument ist auf die Wechselwirkung mit dem Wälzlager des Radsatzlagers in Hinsicht auf den erforderlichen Betrieb begrenzt.

Le présent document fait partie d'un ensemble de normes : EN 12080, EN 12081, EN 12082-1 et EN 12082-2. Le présent document spécifie les principes et les méthodes de déploiement du système composé du (des) roulement(s), du corps de boîte, de la (des) étanchéité(s) et de la graisse, pour assurer la fiabilité de la circulation des trains sur les réseaux européens. Il couvre l’évaluation de la conformité par rapport aux exigences de conception des roulements conformément à l’EN 12080 et de la graisse conformément à l’EN 12081, ainsi que la conduite d’essais (de banc) conformément à l’EN 12082-1. Le présent document a été initialement élaboré pour les applications à boîtes d'essieux extérieures avec des bagues intérieures tournantes, mais il peut également s’appliquer aux véhicules avec une configuration de boîtes d'essieux intérieures avec des bagues intérieures tournantes. Le présent document décrit la procédure de déploiement complète pour des boîtes d’essieu nouvelles et précise le type ainsi que le contenu des essais nécessaires. Une procédure de déploiement réduite est également décrite pour certains cas et sur la base d’une évaluation des risques documentée. Le présent document s’applique uniquement aux boîtes d’essieux équipées avec des roulements et des graisses conformément aux normes EN 12080 et EN 12081. Le domaine d'application de l’EN 12082-2 ne couvre pas les détails techniques des procédures d'essai, ces derniers sont traités dans l’EN 12082-1. Le domaine d’application de l’EN 12082-2 n’intègre pas la définition de la procédure de validation pour les corps de boîte, fourreaux ou couvercles de corps de boîte d’un point de vue structurel. La pertinence de ces parties dans le domaine d’application du présent document est limitée à l’interaction avec les roulements de boîte d’essieu en fonction de l’exploitation requise.
