Abstract

L'invention concerne des joints à brosse. Des éléments de brosse 23 sont assemblés en insérant une multiplicité de filaments 12 dans une pluralité d'éléments de maintien 21, les éléments de brosse étant alors montés sur un support 24. Les extrémités libres des filaments 12 sont fixées à un organe 26 constituant la base du joint à brosse et les filaments 12 sont alors coupés à mi-chemin entre leur tube de maintien 21 et l'organe de base 26. Application aux joints entre rotor et stator.
