Abstract

Unité de générateur éolien, comprenant un système de palier, un rotor (2), un moyeu (3) et un couvercle de guidage d'écoulement (4). Le couvercle de guidage d'écoulement (4) est situé à l'extérieur du moyeu (3); le système de palier comprend une bague extérieure de palier (11) et une bague intérieure de palier (12); et le rotor (2) et le moyeu (3) sont reliés à une partie rotative du système de palier. L'unité de générateur éolien comprend en outre un dispositif de refroidissement de palier comportant plusieurs ouvertures situées sur ou à proximité du couvercle de guidage d'écoulement (4), et l'espace entre le couvercle de guidage d'écoulement (4) et le moyeu (3) est en communication avec l'extérieur au moyen des ouvertures. Au moins une partie du système de palier est exposée à l'espace, et de l'air de refroidissement peut s'écouler dans l'espace à partir des ouvertures pour refroidir le système de palier.
