Abstract
La présente invention concerne un ventilateur axial comportant un rotor à pales réglables dont l'extrémité de base est montée sur le moyeu du rotor par l'intermédiaire d'un tourillon de fixation. Elle est caractérisée en ce que le tourillon de fixation de pale vient buter contre le côté radialement extérieur du moyeu et est soumis à une précontrainte axiale par compression, le tourillon ayant une forme tubulaire et les organes de précontrainte étant constitués par des vis. Elle se rapporte à des ventilateurs industriels.
