(Main)Railway applications - Axleboxes - Performance testing
Railway applications - Axleboxes - Performance testing
This European Standard specifies the principles and methods for a rig performance test of the system of axlebox rolling bearing(s), housing, seal(s) and grease. Test parameters and minimum performance requirements for vehicles in operation on main lines are specified. Different test parameters and performance requirements may be selected for vehicles in operation on other networks (e.g. urban rail). This standard is historically developed for outboard applications but can be used for vehicles with other bearing arrangements (e.g.: inboard application or single wheels).
It gives some possible examples where a "sequenced performance test" addresses the broad range of different service conditions within a specific application or vehicle platform into account.
It describes in detail the water tightness test and basic principles and minimum requirements for a field test.
This European Standard only applies to axleboxes equipped with rolling bearings and greases according to EN 12080 and EN 12081.
Bahnanwendungen - Radsatzlager - Prüfung des Leistungsvermögens
Diese Europäische Norm legt die Grundlagen und Verfahren für die Prüfung des Leistungsvermögens auf dem Prüfstand der Baugruppe Radsatzlager, bestehend aus Wälzlager(n), Lagergehäuse, Dichtung(en) und Schmierfett, fest. Für Fahrzeuge im Betrieb auf Vollbahnen sind die Prüfbedingungen und Mindestleistungsanforderungen spezifiziert. Für Fahrzeuge im Betrieb auf anderen Schienennetzen dürfen davon abweichende Prüfbedingungen und Leistungsanforderungen gewählt werden (z. B. städtische Schienenbahnen). Diese Norm wurde ursprünglich für Außenlagerungen entwickelt, gilt jedoch auch für Fahrzeuge mit anderen Lageranordnungen (z. B. Innenlagerungen oder Einzelräder).
Sie enthält mögliche Beispiele, in denen eine „sequentielle Leistungsprüfung“ die breite Vielfalt von verschiedenen Betriebsbedingungen innerhalb einer spezifischen Anwendung oder einer Fahrzeugplattform berücksichtigt.
Sie beschreibt detailliert eine Wasserdichtheitsprüfung und die Grundlagen und Mindestanforderungen einer Betriebserprobung.
Diese Europäische Norm gilt nur für Radsatzlager, die mit Wälzlagern und Schmierfetten nach EN 12080 und EN 12081 ausgestattet sind.
