Abstract

INVENTION CONCERNANT DES MACHINES ELECTRIQUES. CLAVETTE POUR FERMER LES RAINURES DES PAQUETS DE TOLES D'UN STATOR DE MACHINE ELECTRIQUE. LA CLAVETTE EST CONSTITUEE PAR UNE BANDE PLATE EN TOLE OU MATIERE SYNTHETIQUE, POURVUE D'UNE FENTE LONGITUDINALE ET DE BANDES LATERALES COUDEES S'ADAPTANT DANS LES INDENTATIONS DE LOGEMENT DE LA RAINURE. L'UNE DES BANDES LATERALES AU MOINS PRESENTE UNE PARTIE CINTREE DANS LE SENS LONGITUDINAL, CONVEXE VERS L'EXTERIEUR ET COMPORTE AUSSI UNE FENTE TRANSVERSALE. APPLICATION A LA SUPPRESSION DES DIFFICULTES CAUSEES PAR LES TOLERANCES DE FABRICATION DU DECOUPAGE DES TOLES.INVENTION RELATING TO ELECTRIC MACHINES. KEY FOR CLOSING THE GROOVES OF SHEET PACKAGES OF AN ELECTRIC MACHINE STATOR. THE KEY IS CONSTITUTED BY A FLAT BAND OF SHEET OR SYNTHETIC MATERIAL, PROVIDED WITH A LONGITUDINAL SLOT AND BENDED SIDE BANDS FIT IN THE HOUSING INDENTATIONS OF THE GROOVE. AT LEAST ONE OF THE SIDE BANDS SHOWS A PART BENT IN THE LONGITUDINAL DIRECTION, CONVEX TOWARDS THE EXTERIOR AND ALSO HAS A TRANSVERSE SLIT. APPLICATION TO THE REMOVAL OF DIFFICULTIES CAUSED BY MANUFACTURING TOLERANCES FOR CUTTING SHEETS.
