Abstract[German]
Eine segmentierte Gleitlagerung (1 ) umfasst mehrere Gruppen (4, 5) an Axial-Lagersegmenten (3), welche zur Aufnahme von in einer Welle (10) wirkenden Axialkräften vorgesehen und in Axialrichtung der Welle (10) gegeneinander versetzt sind. Die Welle (10) ist betriebsbedingt durchgebogen, so dass eine Wellenmittellinie (WM) von einer im lastfreien Zustand gegebenen Rotationsachse (RA) der Welle (10) abweicht. Die maximale Abweichung der gekrümmten Wellenmittellinie (WM) von der Rotationsachse (RA) ist zwischen den verschiedenen Gruppen (4, 5) an Axial-Lagersegmenten (3) gegeben.[English]
A segmented sliding bearing (1) comprises multiple groups (4, 5) of axial bearing segments (3) which are intended for absorbing axial forces acting in a shaft (10) and are offset from one another in the axial direction of the shaft (10). Operating conditions cause the shaft (10) to curve, with the result that a shaft centre line (WM) deviates from a prevailing axis of rotation (RA) of the shaft (10) when free of load. The maximum deviation of the curved shaft centre line (WM) from the axis of rotation (RA) prevails between the different groups (4, 5) of axial bearing segments (3).[French]
Un palier lisse segmenté (1) comprend de multiples groupes (4, 5) de segments de palier axiaux (3) qui sont destinés à absorber des forces axiales agissant dans un arbre (10) et qui sont décalés l'un par rapport à l'autre dans la direction axiale de l'arbre (10). Des conditions de fonctionnement amènent l'arbre (10) à s'incurver, avec pour résultat qu'une droite centrale (WM) de l'arbre s'écarte d'un axe de rotation (RA) dominant de l'arbre (10) lorsqu'il est exempt de charge. L'écart maximal de la droite centrale (WM) d'arbre incurvé par rapport à l'axe de rotation (RA) prédomine entre les différents groupes (4, 5) de segments de palier axiaux (3).
