Abstract

PALIER SE COMPOSANT D'UN ARBRE CYLINDRIQUE FIXE SUR LEQUEL EST MONTE UN ELEMENT ROTATIF QUI L'ENTOURE PAR UN ALESAGE CYLINDRIQUE, L'ARBRE COMPORTANT UNE POCHE HYDROSTATIQUE DE PORTEE QUI COOPERE AVEC L'ELEMENT ROTATIF ET QUI COMMUNIQUE PAR L'INTERMEDIAIRE D'UN ETRANGLEMENT AVEC UNE CANALISATION D'ARRIVEE OU DE DEPART D'UN FLUIDE SOUS PRESSION ELEVEE QUI EST REALISEE DANS L'ARBRE. LA SURFACE DE L'ENVELOPPE DE L'ARBRE 1 A AU NIVEAU DE LA POCHE HYDROSTATIQUE DE PORTEE 10 UN RAYON R3 QUI EST PLUS GRAND QUE CELUI R1 DE LA SURFACE DE L'ENVELOPPE VOISINE DE PART ET D'AUTRE DE CETTE POCHE 10 ET LA LONGUEUR DE CE RAYON R3 EST PROCHE DE CELLE DU RAYON R3 DE L'ALESAGE DE L'ELEMENT ROTATIF 2. APPLICATION AUX MOTEURS OU POMPES A PISTONS GUIDES RADIALEMENT DANS UN BLOC MOTEUR ROTATIF.
