Abstract

A un ventilateur à pales flexibles est associé un atténuateur de vibration fixé coaxialement au ventilateur. L'atténuateur comprend un premier support rigide fixé au ventilateur, un second support rigide prévu pour être fixé sur un arbre d'entraînement, et un membre élastique interposé entre le premier et le second support et prévu pour transmettre un couple entre ces deux supports tout en atténuant les vibrations provenant du moteur. Les supports comprennent des moyens pour assurer l'alignement de l'atténuateur coaxialement avec le ventilateur et avec l'arbre d'entraînement et pour positionner les deux supports coaxialement l'un par rapport à l'autre. Application aux ventilateurs de refroidissement pour moteur d'automobile.A flexible blade fan is associated with a vibration attenuator attached coaxially to the fan. The attenuator comprises a first rigid support fixed to the fan, a second rigid support intended to be fixed to a drive shaft, and an elastic member interposed between the first and the second support and adapted to transmit a torque between these two supports while by attenuating vibrations from the engine. The brackets include means for aligning the attenuator coaxially with the fan and with the drive shaft and for positioning the two brackets coaxially with respect to each other. Application to cooling fans for automobile engines.
