Abstract

L'invention illustre un assemblage d'une structure d'un ventilateur axial comprenant un arbre de transmission auquel est apposé un roulement à billes à chaque extrémité de l'arbre. Un ressort est intégré entre les roulement à billes et installé coaxial au rotor et stator pour stabiliser la force centrifuge permettant d'atteindre un meilleur équilibre dynamique de rotation autour de l'axe du ventilateur. Ce type d'assemblage diminue substantiellement le problème de fléchissement de l'arbre.
