Abstract

L'INVENTION CONCERNE LES CONSTRUCTIONS MECANIQUES. LE MOTEUR FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPORTANT UN STATOR 3 A SURFACE INTERNE HELICOIDALE ET UN ROTOR 4 A SURFACE EXTERNE HELICOIDALE PLACE D'UNE FACON EXCENTRIQUE PAR RAPPORT AU STATOR 3, LESDITS ROTOR ET STATOR FORMANT UN COUPLE CINEMATIQUE EN CONTACT PERMANENT SOUS FORME D'UN COUPLE DENTE A ENGRENAGE INTERNE, LE NOMBRE DE DENTS DU STATOR ETANT SUPERIEUR D'UNE DENT A CELUI DU ROTOR ET LE RAPPORT DES PAS DES FILETS DU STATOR ET DU ROTOR ETANT PROPORTIONNEL AU RAPPORT DE LEURS NOMBRES DE DENTS, RESPECTIFS, ET EST CARACTERISE EN CE QUE LE RAPPORT DES PAS RESPECTIFS DES SURFACES HELICOIDALES DU STATOR ET DU ROTOR A LEURS DIAMETRES MOYENS RESPECTIFS SE TROUVE SENSIBLEMENT ENTRE5,5 ET12. LE MOTEUR EN QUESTION PEUT ETRE UTILISE AVEC LE PLUS DE SUCCES DANS LES MOTEURS D'ATTAQUE HELICOIDAUX HYDRAULIQUES POUR FORER LES PUITS DE PETROLE, DE GAZ ET D'EXPLORATION GEOLOGIQUE.
