(FR) MOULE POUR LA FABRICATION D'UN VENTILATEUR POSSEDANT UN MOYEU ET PLUSIEURS PALES HELICOIDALES S'ETENDANT DEPUIS CE DERNIER
Abstract
(EN)
A mould for the manufacture of a fan having a hub and a plurality of helical blades extending from the hub, the mould having blade moulding cavities which are formed such that (a) any imaginary line extending from the rotational axis of the fan to be formed in the mould and through the blade cavity from the blade root to the blade tip intersects the rotation axis at the same angle as any other imaginary line extending in a similar manner, (b) all the imaginary lines are identical in curvature, or are all linear, and, (c) any said imaginary line can exactly replace any other said imaginary line.
(FR)
L'invention concerne un moule pour la fabrication d'un ventilateur possédant un moyeu et plusieurs pales hélicoïdales s'étendant depuis le moyeu, le moule présentant des cavités de moulage de pale, formées de sorte que: (a) une ligne imaginaire s'étendant depuis l'axe de rotation du ventilateur à former dans le moule, et au travers de la cavité pour pale, depuis l'emplanture de la pale jusqu'à son extrémité, coupe l'axe de rotation selon le même angle que tout autre ligne imaginaire s'étendant de manière similaire; (b) toutes les lignes imaginaires présentent une courbure identique ou sont toutes linéaires, et (c) toutes les lignes imaginaires peut se remplacer mutuellement.
