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 solidaire de la deuxième bague 14 du palier et de la douille 24. La douille comprend au moins une saillie 30, 32 venant en appui contre la garniture d’isolation 26 au moins dans le sens axial. Référence : Figure 1
