Title (EN) SLEW BEARING, METHOD FOR USING A SLEW BEARING, HOISTING CRANE AND VESSEL
(FR) PALIER DE PIVOTEMENT, PROCÉDÉ D'UTILISATION D'UN PALIER DE PIVOTEMENT, GRUE DE LEVAGE ET NAVIRE
Abstract:
(EN) The invention relates to a slew bearing comprising a stationary bearing ring to be fixed to a base, a moveable bearing ring to be fixed to a moveable object, wherein the stationary bearing ring and the moveable bearing ring are configured to enable rotation of the moveable bearing ring relative to the stationary bearing ring about a rotation axis. A main axial bearing and an auxiliary bearing are provided between the stationary bearing ring and the moveable bearing ring, wherein the moveable bearing ring comprises one or more main portions and one or more auxiliary portions, which one or more main portions are moveable relative to the one or more auxiliary portions between an operational position, in which the main axial bearing transfers the axial loads between moveable bearing ring and stationary bearing ring, and a raised maintenance position, in which the auxiliary axial bearing transfers the axial loads between moveable bearing ring and stationary bearing ring and the main bearing is allowed to be inspected and/or maintained so that the slew bearing during inspection and/or maintenance is still operational.
(FR) L'invention concerne un palier de pivotement comprenant une bague de palier fixe destinée à être fixée à une base, une bague de palier mobile destinée à être fixée sur un objet mobile, la bague de palier fixe et la bague de palier mobile étant conçues pour permettre la rotation de la bague de palier mobile par rapport à la bague de palier fixe autour d'un axe de rotation. Un palier axial principal et un palier auxiliaire sont disposés entre la bague de palier fixe et la bague de palier mobile, la bague de palier mobile comprenant une ou plusieurs parties principales et une ou plusieurs parties auxiliaires, une ou plusieurs parties principales étant mobiles par rapport à la ou aux parties auxiliaires entre une position opérationnelle, dans laquelle le palier axial principal transfère les charges axiales entre la bague de palier mobile et la bague de palier fixe, et une position de maintenance élevée, dans laquelle le palier axial auxiliaire transfère les charges axiales entre la bague de palier mobile et la bague de palier fixe et le palier principal peut être inspecté et/ou entretenu de telle sorte que le palier de pivotement reste opérationnel pendant l'inspection et/ou l’entretien.
