Abstract
(EN)
The invention relates to a bearing, which comprises at least two groups radial stable magnetic rings and at least one group axial stable magnetic ring designed between the radial stable magnetic rings. The radial stable magnetic ring consists of a radial static magnetic ring fixed to a bearing housing and a radial movable magnetic ring which is parallel to the radial static magnetic ring and fixed to a shaft sleeve extends in the radial direction. Both the radial static magnetic ring and the radial movable magnetic ring are composed of more than two cross magnetic poles that are closely connected in the radial direction. The structure of the axial stable magnetic ring designed axially is the same as this of the radial stable magnetic ring. The invention is of simple design and large power.

L'invention concerne un roulement qui comprend au moins deux anneaux magnétiques stables radiaux et au moins un groupe d'anneaux magnétiques stables axiaux désignés entre les anneaux magnétiques stables radiaux. L'anneau magnétique stable radial se compose d'un anneau magnétique statique radial fixé à un boîtier de roulement et d'un anneau magnétique movible radial qui est parallèle à l'anneau magnétique statique radial et fixé à un manchon s'étendant dans le sens radial. L'anneau magnétique statique radial, à l'instar de l'anneau magnétique movible radial, est composé de plus de deux pôles magnétiques qui se croisent et sont reliés dans le sens radial. La structure de l'anneau magnétique stable axial conçu axialement est identique à celle de l'anneau magnétique stable radial. L'invention est simple à concevoir et fait preuve d'une forte puissance.
