Title (EN) ROLLING BEARING ARRANGEMENT FOR A TRANSMISSION
(FR) ENSEMBLE PALIER À ROULEMENT POUR UNE TRANSMISSION
(DE) WÄLZLAGERANORDNUNG FÜR EIN GETRIEBE
Abstract:
(EN) The invention relates to a rolling bearing arrangement (1) for a transmission (2) of a wind turbine, comprising a rolling bearing (3) with an outer ring (4), an inner ring (5) and a plurality of rolling bodies (6) rolling between the outer ring (4) and the inner ring (5), the outer ring (4) and/or the inner ring (5) comprising at least one sensor element (9) for detecting and monitoring a state variable, the at least one sensor element (6) comprising a load measuring bolt (7) with at least one strain gauge (8) and being directly positioned in a force flow path of the state variable, the state variable being at least one bearing preload of the rolling bearing (3).
(FR) L’invention concerne un ensemble palier à roulement (1) pour une transmission (2) d’éolienne, lequel ensemble palier à roulement comprend un palier à roulement (3) doté d’une bague extérieure (4), d’une bague intérieure (5) et d’une pluralité de corps de roulement (6) roulant entre la bague extérieure (4) et la bague intérieure (5), la bague extérieure (4) et/ou la bague intérieure (5) présentant au moins un élément de détection (9) pour détecter et surveiller une grandeur d’état, ledit au moins un élément de détection (6) comportant un tourillon de mesure de force (7) doté d’au moins une jauge extensométrique (8), ledit au moins un élément détecteur (9) étant positionné directement dans une voie d’écoulement de force de la grandeur d’état, ladite grandeur d’état étant au moins une précontrainte de roulement dudit palier à roulement (3).
(DE) Wälzlageranordnung (1) für ein Getriebe (2) einer Windkraftanlage, umfassend ein Wälzlager (3) mit einem Außenring (4), einem Innenring (5) und einer Vielzahl von zwischen Außenring (4) und Innenring (5) abrollender Wälzkörper (6), wobei der Außenring (4) und/oder der Innenring (5) mindestens ein Sensorelement (9) zur Erfassung und Überwachung einer Zustandsgröße aufweisen, wobei das mindestens eine Sensorelement (6) einen Kraftmessbolzen (7) mit mindestens einem Dehnungsmessstreifen (8) umfasst, wobei das mindestens eine Sensorelement (9) unmittelbar in einem Kraftflusspfad der Zustandsgröße positioniert ist, wobei die Zustandsgröße zumindest eine Lagervorspannung des Wälzlagers (3) ist.
