Beschreibung
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 presente invención se refiere a una máquina eléctrica giratoria que incluye una carcasa que forma una cavidad interna que aloja un conjunto rotor/estator, en donde el rotor está posicionado sobre un eje principal (2) de la máquina, un depósito de fluido lubricante (3) definiendo una porción de carcasa (3a) que define una superficie interior, y al menos un cojinete de rodillos (4) acoplado al eje principal (2) y soportado por la porción de carcasa (3a) y por un buje (5). La máquina incluye un anillo de aceite (7) sujetado al buje (5) y dispuesto entre el eje principal (2) de la máquina y la superficie interior de la parte de la carcasa (3a), donde el anillo de aceite (7) incluye una pared que posee una sección transversal sustancialmente circular (7a) y al menos una proyección alargada e inclinada (8) en una superficie exterior de la pared (7a), cada proyección alargada e inclinada posee un borde inferior (8a) y un borde superior (8b) y en donde el giro del anillo de aceite genera una diferencia de presión entre el borde inferior (8a) y el borde superior (8b) para forzar el lubricante hacia al menos un cojinete de rodillos (4).
