Title
(DE) ELASTISCHE GELENKE MIT TORSIONSANSCHLAG UND IHRE VERWENDUNG IN SCHWINGUNGSTILGERN
(EN) ELASTIC JOINTS HAVING A TORSIOL STOP AND OF SUCH JOINTS IN VIBRATION ABSORBERS
(FR) ARTICULATIONS ÉLASTIQUES COMPRENANT UNE BUTÉE DE TORSION ET UTILISATION ASSOCIÉE DANS DES AMORTISSEURS DE VIBRATIONS
Abstract
(DE)
Die Erfindung betrifft neuartige elastische Torsions-Anschlagbauteile auf Basis von mehrschichtigen Elastomer-Metall Elementen in zylindrischer, konischer oder sphärischer Form, welche besonders geeignet sind, um als wartungsfreie und verschleißarme Gelenke mit großer Winkelspreizung, beispielsweise in Schwingungstilgern, z.B. in Pendel- Schwingungstilgern von Windkraftanlagen, eingesetzt werden zu können.
(EN)
The invention relates to novel elastic torsion stop components based on multilayer elastomer metal elements in cylindrical, conical, or spherical shape, which are particularly suitable for use as maintenance-free and low-wear joints having a large angular spread, for example in vibration absorbers, such as in pendulum vibration absorbers of wind turbines.
(FR)
L'invention concerne des composants de butée de torsion élastiques innovants à base d'éléments en élastomère-métal multicouches sous une forme cylindrique, conique ou sphérique, lesquels sont particulièrement adaptés pour pouvoir être employés en tant qu'articulations sans maintenance et à faible usure présentant un grand écartement angulaire, par exemple dans des amortisseurs de vibrations, par exemple dans des amortisseurs de vibrations pendulaires d'éoliennes.
