Description
Ensemble de faux rotors pour machines à bobiner les stators de machines électriques La présente invention a trait à un ensemble de faux rotors pour machines à bobiner les stators de machines électriques telles que celles décrites dans les brevets Nos 267789 et <B>275587.</B> L'ensemble des faux rotors comportant sur leur face extérieure des encoches longitudina les, correspondant à celles du stator considéré, dans lesquelles sont disposés au préalable des enroulements qu'on fait ensuite passer dans celles du stator à bobiner par poussée radiale, après avoir disposé au préalable le faux rotor dans l'axe du stator, et comportant des fusées destinées à être prises en butée par des arbres centraux de la machine à bobiner;
est carac térisé en ce que les différents faux rotors de dimensions différentes utilisés pour le bobinage de stators de longueurs de fer différentes, ont tous des fusées de la même longueur.
Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention. La fig. 1 est une vue de profil d'un faux rotor, de l'ensemble ; la fig. 2 est une vue partielle en élévation perpendiculairement à son axe ; et la fig. 3 est un développement partiel de la périphérie du rotor. Le faux rotor est composé d'un corps cy lindrique 1 massif, dont le diamètre extérieur est déterminé pour laisser le jeu minimum 2 entre faux rotor et stator compatible avec une introduction facile du bobinage dans le stator 3, et de deux fusées 4, de diamètre moindre, qui sont prises en butée par les arbres centraux de la machine à bobiner.
La longueur de ce faux rotor 1 doit être prévue légèrement supérieure à celle du stator 3, dans les encoches duquel doit être introduit le bobinage. Les encoches 5, taillées dans ce faux rotor, sont rectangulaires et présentent à leurs flancs parallèles, sur la hauteur occupée par le bobinage, des chanfreins 6, évitant les angles vifs susceptibles d'abîmer les fils ou les fermetures d'encoches. Les languettes de cen trage 8 du faux rotor dans le stator sont cons tituées par deux parties 8a et 8b disposées à chaque extrémité du faux rotor.
En outre, la largeur des. encoches du faux rotor 5 est choisie inférieure à celle de la fente des encoches du stator 7, par où se fait .l'in troduction du fil, d'une valeur déterminée à l'avance dépendant en particulier de la dimen sion de cette fente des encoches stator.
Pour assurer dans les conditions les plus économiques le bobinage à la machine de sta tors de même diamètre d'alésage mais de lon- gueurs de fer différentes, les fusées des faux rotors de l'ensemble sont, selon l'invention, prévues de longueur constante A, quelle que soit la longueur du faux rotor.
The present invention relates to a set of false rotors for machines for winding the stators of electric machines such as those described in patents Nos. 267789 and <B> 275587. </ B> The set of false rotors comprising on their outer face longitudinal notches, corresponding to those of the stator considered, in which windings are arranged beforehand which are then passed through those of the stator to be wound by radial thrust, after have previously arranged the false rotor in the axis of the stator, and comprising rockets intended to be taken into abutment by central shafts of the winding machine;
is characterized in that the different dummy rotors of different dimensions used for winding stators of different iron lengths all have spindles of the same length.
The drawing represents, by way of example, an embodiment of the object of the invention. Fig. 1 is a side view of a dummy rotor, as a whole; fig. 2 is a partial elevational view perpendicular to its axis; and fig. 3 is a partial development of the periphery of the rotor. The false rotor is composed of a solid cylindrical body 1, the outer diameter of which is determined to leave the minimum clearance 2 between false rotor and stator compatible with easy introduction of the winding into the stator 3, and two rockets 4, of smaller diameter, which are caught in abutment by the central shafts of the winding machine.
The length of this false rotor 1 must be provided slightly greater than that of the stator 3, in the notches of which the winding must be inserted. The notches 5, cut in this false rotor, are rectangular and have at their parallel sides, over the height occupied by the winding, chamfers 6, avoiding sharp angles liable to damage the wires or the notch closures. The centering tabs 8 of the false rotor in the stator are constituted by two parts 8a and 8b arranged at each end of the false rotor.
In addition, the width of. the notches of the false rotor 5 is chosen less than that of the slot of the slots of the stator 7, through which the wire is introduced, by a value determined in advance depending in particular on the size of this slot stator notches.
To ensure under the most economical conditions the machine winding of sta tors of the same bore diameter but of different iron lengths, the spindles of the false rotors of the assembly are, according to the invention, provided of length. constant A, whatever the length of the false rotor.
