Abstract
[Dispositif de palier à isolation électrique intégrée, notamment pour moteur ou machine électrique] Le dispositif de palier comprend un palier 10 pourvu d’une première bague 12 et d’une deuxième bague 14 aptes à tourner l’une par rapport à l’autre. Le dispositif comprend au moins un manchon d’isolation 22 monté sur la deuxième bague 14 du palier et pourvu d’une douille 24 et d’une garniture d’isolation 26 interposée radialement entre la deuxième bague 14 et la douille 24 et réalisée en matériau isolant électrique. La garniture d’isolation 26 est surmoulée sur la deuxième bague 14 du palier et sur la douille 24. La douille 24 est pourvue d’au moins un évidement 28 à l’intérieur duquel s’étend une protubérance 30 d’accrochage de la garniture d’isolation de forme complémentaire audit évidement.
