A sealing device intended for sealing between an axle journal (21, 22, 23, 24) and a bearing housing (30, 57, 31, 58) for the axle journal (21, 22, 23, 24). The sealing device allows that the axle journal (21, 22, 23, 24) can be angled in a plane in relation to the bearing housing and can also take up axial movement. The sealing device comprises a stator ring (40), which is carried by two guide pins (41), and the stator ring (40) can be angled in a plane in relation to the guide pins (41). The sealing device comprises also a sealing ring unit (47), which is intended for sealing between the stator ring (40) and axle journal (21, 22, 23, 24), a bellow means (56), which is intended for sealing between the bearing housing (30, 57, 31, 58) and stator ring (40), and at least one resilient element (48), which is intended to ensure that the stator ring (40) abuts the sealing ring unit (47). The bellows means (56) can be made of a material withstanding aggressive liquids.
L'invention concerne un dispositif d'éthanchéité servant à obturer un espace entre une fusée d'essieu (21, 22, 23, 24) et un corps de roulement (30, 57, 31, 58) pour la fusée d'essieu (21, 22, 23, 24). Le dispositif d'éthanchéité permet d'incliner la fusée d'essieu (21, 22, 23, 24) sur un plan, relativement au corps de roulement, et de lui imprimer également un mouvement axial. Le dispositif d'éthanchéité comprend un stator annulaire (40) porté par deux broches de guidage (41) et pouvant être incliné sur un plan relativement à des broches de guidage (41). Le dispositif d'éthanchéité comprend également un anneau unitaire d'éthanchéité (47) destiné à obturer un espace entre le stator annulaire (40) et la fusée d'essieu (21, 22, 23, 24); un moyen à soufflet (56) conçu pour obturer un espace entre le corps de roulement (30, 57, 31, 58) et le stator annulaire (40); et au moins un élément résilient (48) ayant pour fonction d'assurer que le stator annulaire (40) jouxte l'anneau unitaire d'éthanchéité (47). Le moyen à soufflet (56) peut être fabriqué dans un matériau résistant aux liquides agressifs.
