Zusammenfassung: | A vibration motor has a multistage concentrator for longitudinal and torsional vibrations. It is used in sound recording and reproduction equipment. The concentrator copes with ultrasonic vibration. One stage is in contact with a piezo-electric cell. The second stage, which is the driver, is in contact with the rotor. The rotor is mounted coaxially w.r.t. the concentrator. The contact surfaces (6, 7) of the driving stage (3) of the concentrator (1) and the rotor (8) are cone-shaped. They form a tapered clutch. The first stage of the concentrator is cylindrical with the piezo-electric cell (5) at one end. The electrodes of the cell are connected to a h.f. oscillator.
L'INVENTION CONCERNE LES MOTEURS ELECTRIQUES.LE VIBROMOTEUR FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPRENANT UN CONCENTRATEUR ETAGE 1 D'OSCILLATIONS ULTRASONORES, DONT L'UN DES ETAGES 2 EST EN CONTACT AVEC UN ELEMENT PIEZOELECTRIQUE OU PIEZOELEMENT 5, ET DONT L'AUTRE ETAGE 3, OU ETAGE ENTRAINEUR, EST EN CONTACT AVEC UN ROTOR 8 DISPOSE COAXIALEMENT AUDIT CONCENTRATEUR, ET EST CARACTERISE EN CE QUE LES SURFACES DE CONTACT DE L'ETAGE ENTRAINEUR 3 DU CONCENTRATEUR 1 ET DU ROTOR 8 SONT CONIQUES, DE FACON A FORMER ENTRE ELLES UN JOINT CONIQUE.L'INVENTION PEUT ETRE UTILISEE EN PARTICULIER DANS LES DISPOSITIFS D'ENREGISTREMENT ET DE REPRODUCTION D'INFORMATIONS SONORES, PAR EXEMPLE DANS LES ELECTROPHONES. |
