Title
(DE) LAGER MIT ENERGIEERZEUGUNGSEINHEIT
(EN) BEARING HAVING A POWER GENERATION UNIT
(FR) PALIER À UNITÉ DE PRODUCTION D'ÉNERGIE
Abstract
(DE)
Die Erfindung betrifft ein Lager mit einem ersten Lagerring (2) und einem zweiten Lagerring (3) sowie mit einer Energieerzeugungseinheit (6) nach Art eines Klauenpolgenerators. Die Aufgabe, ein Lager mit einer im wesentlichen bauraumneutralen Energieerzeugungseinheit mit einem hohen Füllfaktor für die Induktionsspule anzugeben, wird erfindungsgemäß dadurch gelöst, dass jeder der beiden Klauenringe (16, 25) in magnetisch leitender Verbindung mit einem Abschnitt (31) des Korpus des ersten Lagerrings (2) angeordnet ist, und dass der magnetische Kreis im wesentlichen über den Abschnitt (31) des Korpus des ersten Lagerrings (2) geschlossen wird.
(EN)
The invention relates to a bearing comprising a first bearing ring (2) and a second bearing ring (3) as well as a claw pole generator-type power generation unit (6). The aim of the invention is to devise a bearing comprising a substantially space-neutral power generation unit which has a high filling factor for the induction coil. Every claw ring (16, 25) is connected to a section (31) of the body of the first bearing ring (2) in a magnetically conducting fashion and the magnetic circuit is substantially closed via the section (31) of the body of the first bearing ring (2).
(FR)
L'invention concerne un palier comprenant une première bague de palier (2) et une seconde bague de palier (3) ainsi qu'une unité de production d'énergie (6) du type alternateur à griffes. Le but de l'invention est de fournir un palier pourvu d'une unité de production d'énergie n'augmentant sensiblement pas l'encombrement du palier et dont la bobine d'induction possède un facteur de remplissage élevé. A cet effet, chacune des deux bagues à griffes (16, 25) est placée en liaison magnétiquement conductrice avec une partie (31) du corps de la première bague de palier (2) et le circuit magnétique est fermé sensiblement par l'intermédiaire de cette partie (31) du corps de la première bague de palier (2).
