Abstract

L'invention concerne un moyeu centrifuge à pas variable pour aéromoteur comprenant un corps de moyeu (1) comprenant un arbre de moteur (4) en son centre, des axes reliant des pales (2) répartis régulièrement autour de la périphérie extérieure du corps de moyeu, etc. La ligne centrale d'un axe reliant les pales est tangente à un cercle qui prend le centre du corps de moyeu comme centre. Une extrémité de l'axe reliant les pales est fixée sur le corps de moyeu via un roulement à billes à rainure profonde (5) et un écrou cylindrique (6), l'autre extrémité étant une extrémité de fixation de pale (8) dotée d'un marteau centrifuge(3) fixé à sa partie arrière. Le moyeu présente une conception de structure raisonnable, une bonne stabilité et un effet de variation de pas remarquable.
