BROCHE.A. MOTEUR CONCENTRIQUE.
La présente invention est relative à un dispositif de broche des- tinée à commander un outil ou une pièce d'une machine-outil.
Le dispositif, objet de l'invention, se caractérise en ce qu'il réalise le montage, sur un axe géométrique commun,, de la broche de sortie d'une machine-outil et du moteur électrique qui commande cette broche; cette commande peut avoir lieu directement ou indirectement, suivant le type de machine-outil envisagé, telle que tour, fraiseuse, perceuse, étau-limeur, etc...
L'agencement prévu par un tel dispositif a pour avantage de réaliser une commande entièrement symétrique, présentant un encombrement réduit et formant un tout facilement démontableo
Sur le dessin annexé, on a représenté, à titre d'exemple non li- mitatif de la présente invention, un mode de réalisation de celle-ci dans lequel la figure unique représente schématiquement en coupe, le dispositif objet'de l'inventiono
Sur la figure, la broche 1 est contenue dans un bâti 2 dans la partie droite duquel est fixé un moteur électrique dont le rotor 3 est so- lidaire du manchon 4,monté sur la broche 1. Le stator est représenté en 5.
Le manchon 4 porte à son extrémité, située à la partie centrale du bâti 2, un pignon 6 qui coopère par exemple avec un train d'engrenages à rapport constant ou variable, tel que 7, ou avec tout autre dispositif multiplicateur ou démultiplicateur de vitesse.
On peut interposer un dispositif à friction statique 8 dans la transmission. Ce dispositif, réglé convenablement, par exemple à 150 % de la charge normale, supprime l'inconvénient, tel que les à-coups, provoqué par l'entraînement direct, en même temps qu'il élimine aussi ceux de l'en- traînement par courroie, par exemple, le glissement ou la perte de puissance.

BROOCH.A. CONCENTRIC MOTOR.
The present invention relates to a spindle device intended to control a tool or a part of a machine tool.
The device, object of the invention, is characterized in that it assembles, on a common geometric axis, the output spindle of a machine tool and the electric motor which controls this spindle; this command can take place directly or indirectly, depending on the type of machine tool envisaged, such as a lathe, milling machine, drill, vice-filer, etc.
The arrangement provided by such a device has the advantage of producing an entirely symmetrical control, having a reduced bulk and forming an easily removable whole.
In the accompanying drawing, there is shown, by way of non-limiting example of the present invention, an embodiment thereof in which the single figure shows schematically in section, the device object of the invention.
In the figure, the spindle 1 is contained in a frame 2 in the right part of which is fixed an electric motor whose rotor 3 is integral with the sleeve 4, mounted on the spindle 1. The stator is represented at 5.
The sleeve 4 carries at its end, located at the central part of the frame 2, a pinion 6 which cooperates for example with a constant or variable ratio gear train, such as 7, or with any other speed multiplier or multiplier device .
A static friction device 8 can be interposed in the transmission. This device, suitably adjusted, for example at 150% of the normal load, eliminates the inconvenience, such as jerks, caused by the direct drive, at the same time as it also eliminates those of the drive. by belt, for example, slip or loss of power.
