Title (EN) DEVICE PROVIDED WITH A BEARING-IN-BEARING
(FR) DISPOSITIF POURVU D'UN PALIER DANS UN PALIER
Abstract:
(EN) Device provided with a bearing-in-bearing (1) with an inner ring (2), an intermediate ring (3) and an outer ring (4), whereby between the inner ring (2) and the intermediate ring (3) and between the intermediate ring (3) and the outer ring (4), inner roller elements (5), outer roller elements (6) are attached respectively, whereby the bearing-in-bearing (1), with its inner ring (2) and outer ring (4), is attached between two components in the device that can rotate in relation to each other, a shaft (11) and a housing (12), of which one component (11 or 12) is or can be connected to a drive, characterized in that the device is provided with a transmission between the intermediate ring (3) and the driven component (11 or 12) in order to drive the intermediate ring (3), wherein this transmission is a contactless transmission.
(FR) Le dispositif selon l'invention est pourvu d'un palier dans un palier (1) doté d'un anneau interne (2), d'un anneau intermédiaire (3) et d'un anneau externe (4), moyennant quoi, entre l'anneau interne (2) et l'anneau intermédiaire (3) et entre la bague intermédiaire (3) et la bague externe (4), des éléments (5) de rouleau interne, des éléments (6) de rouleau externe sont fixés respectivement, moyennant quoi le palier dans un palier (1), doté de son anneau interne (2) et de son anneau externe (4), est fixé entre deux éléments dans le dispositif qui peuvent tourner l'un par rapport à l'autre, un arbre (11) et un boîtier (12), dont un élément (11 ou 12) est ou peut être relié à un entraînement, caractérisé en ce que le dispositif est pourvu d'une transmission entre l'anneau intermédiaire (3) et l'élément (11 ou 12) entraîné pour entraîner l'anneau intermédiaire (3), cette transmission étant une transmission sans contact.
