Zusammenfassung: | The present invention relates to a rotary electric machine that includes a housing that forms an internal cavity that houses a rotor/stator assembly, in which the rotor is positioned on a main shaft (2) of the machine, a lubricating fluid reservoir (3) defining a hub portion (3a) defining an inner surface, and at least one roller bearing (4) coupled to the main shaft (2) and supported by the hub portion (3a) and by a bushing (5). The machine includes an O-ring (7) fastened to the bushing (5) and arranged between the main shaft (2) of the machine and the inner surface of the hub portion (3a), in which the O-ring (7) includes a wall having a substantially circular cross section (7a) and at least one elongate and inclined projection (8) on an outer surface of the wall (7a), each elongate and inclined projection having a lower edge (8a) and an upper edge (8b) and in which the rotation of the O-ring generates a pressure difference between the lower edge (8a) and the upper edge (8b) to force the lubricant towards the at least one roller bearing (4).
La présente invention concerne une machine électrique tournante du type comprenant une armature délimitant une cavité interne qui loge un ensemble rotor/stator, le rotor étant disposé dans un axe principal (2) de la machine, un réservoir de fluide lubrifiant (3) délimitant une partie de moyeu (3a) définissant une surface intérieure, et au moins un roulement (4) accouplé à l'axe principal (2) et supporté par la partie de moyeu (3a) et par une douille (5). La machine comprend une bague de lubrification (7) fixée à la douille (5) et disposée entre l'axe principal (2) de la machine et la surface intérieure de la partie de moyeu (3a), la bague de lubrification (7) comportant une paroi de section transversale sensiblement circulaire (7a) et au moins une saillie allongée et inclinée (8) sur une surface extérieure de la paroi (7a), chaque saillie allongée et inclinée possédant un bord inférieur (8a) et un bord supérieur (8b), la rotation de la bague de lubrification produisant une différence de pression entre le bord inférieur (8a) et le bord supérieur (8b) pour forcer le lubrifiant en direction d'au moins un roulement (4).
A presente invenção refere-se a uma máquina elétrica girante do tipo que compreende uma carcaça que delimita uma cavidade interna que aloja um conjunto rotor/estator, sendo o rotor disposto em um eixo principal (2) da máquina, um reservatório de fluido lubrificante (3) definindo uma parte de cubo (3a) def |
