Description

1VTagneto d'6elairage. Lobjet de la presente invention est une magneto d'eclairage ä aimant taurnant, notamment pour cyciles, dans laquelle 1e sta- tor est forme ,de pikes de töle -6gales entre elles et maintenues appuyks les unes contre les autres par un bandage circulaire. Dans une forme @.d'exeeution prbf6ree de Vinven- tion, ce handage est constitw6 par 1'enveloppe ext & rieure de la magnko. Les pikes de töle sont alors recourbees pour former les noyaux des bobines et les päles de 1a machine. 1VTagneto of lighting. The object of the present invention is a rotating magnet lighting magneto, in particular for cycles, in which the stator is formed of sheet metal pins which are equal to each other and held pressed against each other by a circular bandage. In a preferred embodiment of the invention, this handing is constituted by the outer casing of the magnko. The sheet metal picks are then bent to form the cores of the coils and the blades of the machine.

Le dessin repr6sente, ä titre d'exemple, une forme d'ex6cution -d'une magneto d'eclai- rage selon la presente invention. 11 n'est mon- tre .de la machine que ce @qui est nkessaire pour la compr6lhension de ce qui va suivre. The drawing shows, by way of example, one embodiment of a lighting magneto according to the present invention. Only what is shown of the machine is necessary for the understanding of what is to follow.

La fig. 1 est une coupe par faxe de la magneto; la fig. 2 est une vue en perspective dune pike de töle isolee; la fig. 3, est une coupe selon la ligne III-III de la fig. 1. fig. 1 is a fax cut of the magneto; fig. 2 is a perspective view of an isolated sheet metal pike; fig. 3, is a section along the line III-III of FIG. 1.

Dans un carter 1, oü sont log6s les pa- liers 2 de la magn6to, tourne sur des cönes un axe 3 qui poste, ä celle de ses extremites qui depasse 1e carter, une poülie Jentrainement 4 maintenue par un krou 5. A 1'extr & mite inte- rieure de faxe 3: est .ca1e un aim@ant perma nent 6, hexapo1aire, qui constitue S'indueteur -de la magn6to. In a casing 1, where the bearings 2 of the magneto are housed, a shaft 3 rotates on cones which posts, at that of its ends which projects beyond the casing, a drive pulley 4 held by a krou 5. At 1' inner end of fax 3: is wedged a permanent magnet 6, hexapole, which constitutes the inductor -of the magneto.

A 1'intericur de la partie cylindrique 7 du carter s.ont dispos:6es des pieces .de töles re- courb6es egales entre dlles, qui sont speciale- ment montr6es en fig. 2 et :qui comportent une partie bombee 9, dont la courbure carrespond ä @calle de 1'int6rieur de 7.a partie eylindrique 7. Cette paxtie bombee est flanqu6e d'oreilles radiales 10 et 11. Inside the cylindrical part 7 of the casing are arranged parts of curved sheets equal between sheets, which are specially shown in FIG. 2 and: which comprise a domed part 9, the curvature of which corresponds to the calle of the interior of 7.a eylindrical part 7. This domed paxtie is flanked by radial lugs 10 and 11.

L'oreillle 11 se prolonge en une partie 12 de courbure concentrique ä la partie bombee 9 et -qui forme, lorsque les pieces de töle sont en place dann le,dynamo comme il est montre dans la fig. 3, d'un des pöles. de 1a machine. Ear 11 extends into a part 12 of curvature concentric with curved part 9 and -which forms, when the sheet metal parts are in place in the dynamo, as shown in FIG. 3, of one of the poles. of the machine.

Chaque pike de töle est, Jans 1e eas par ticulier de longueur.cireulaire correspondant exactement ä un sixieme,de-la p6riphärie to tale, mais il est bien entendu que ce nombre pourrait varier avec celui des poles de la machine. Lorsque les pikes de töle sont pla- c6es les unes ä üöte des autres, elles tiennent exactement la place limitee par la Partie cylindrique 7 du carter. Celle-ei encercle donc toutes ces pikes et les maintient fortement Pressees les unes contre les autres. Ellles forment un tout parfaitement stable. Each sheet metal pick is, in a particular case, of circular length corresponding exactly to one sixth of the total periphery, but it is understood that this number could vary with that of the poles of the machine. When the sheet metal pegs are placed next to each other, they occupy exactly the space limited by the cylindrical part 7 of the casing. This one therefore encircles all these pikes and keeps them strongly pressed against each other. They form a perfectly stable whole.

La construetion pr6decrite faeilite beau- coup la fabrication, 1e montage et 1e bobinage de 1a maehine. En effet, oha.que bobine peut etre faite pour elle-meme sur une machine extremement simple et ä Brande vitesse pour etre ensuite simplement enfilee sur 1e noyau qui est ici forme par les oreilles 10 et 11 de chaque piece de töle. The construction described above greatly facilitates the manufacture, assembly and winding of the machine. Indeed, oha.que coil can be made for itself on an extremely simple machine and at high speed to then be simply threaded on the first core which is here formed by the ears 10 and 11 of each piece of sheet metal.

Le fonetionnement de la maehine est connu. The operation of the machine is known.
