In a wind power installation with a (hollow) axis tube member and a hollow shaft mounted thereon for the rotor there is provided only a single bearing which also carries moments, between the axis tube member and the hollow shaft, whereby the parts of the machine which are to be fixed to the machine carrier and thus on the top of the pylon are of a markedly lower weight without the required orientation between the rotating and stationary parts of the electrical generator being adversely affected. In that arrangement the rotating part of the generator is radially aligned substantially with the bearing. The bearing to be used is in particular a twin-row inclined roller bearing with rows of rollers arranged at an angle of about 45° relative to each other.
L'invention concerne une éolienne pourvue d'un manchon axial (20) (creux) sur lequel est monté un arbre creux (11) destiné au rotor. Cette éolienne ne comprend qu'un seul palier (15), qui absorbe également les couples, entre ledit manchon axial et l'arbre creux, ce qui réduit nettement le poids des parties de machine à fixer sur le support de machine (4) et ainsi à la pointe de la tour, cela sans que l'alignement nécessaire entre les parties tournante et fixe du générateur électrique n'en souffrent. La partie de générateur tournante (10) est alignée radialement sensiblement avec le palier. Comme palier on utilise en particulier un palier à deux rangées de rouleaux obliques, lesquelles forment entre elles un angle d'environ 45 DEG .
