Abstract

A.MECANISME D'ENTRAINEMENT PAS A PAS POUR REALISER UN POSITIONNEMENT TRES PRECIS D'UNE TABLE DE TABLE DE TRAVAIL REGLABLE EN HAUTEUR. B.CE MECANISME D'ENTRAINEMENT SE CARACTERISE NOTAMMENT EN CE QU'IL COMPORTE UN STATOR POURVU DE SYSTEMES POLAIRES ET D'UN ROTOR A LA ROTATION DUQUEL EST ASSOCIE UN DEPLACEMENT AXIAL, CE STATOR ET CE ROTOR ETANT EN PRISE MAGNETIQUEMENT PAR L'INTERMEDIAIRE D'UN FILETAGE DE PRECISION, ET LA TABLE ELEVATRICE ETANT MUNIE D'UN DISPOSITIF L'EMPECHANT DE TOURNER. C.L'INVENTION S'APPLIQUE PRINCIPALEMENT AUX TABLES ELEVATRICES, PAR EXEMPLE POUR REALISER DES SYSTEMES DE REGLAGE ET, ENTRE AUTRES, DES EQUIPEMENTS AUTOMATIQUES SERVANT A LA FABRICATION DE SEMI-CONDUCTEURS.A. STEP-BY-STEP DRIVE MECHANISM TO REALIZE A VERY PRECISE POSITIONING OF A HEIGHT ADJUSTABLE WORK TABLE. B. THIS DRIVE MECHANISM IS CHARACTERIZED IN PARTICULAR IN THAT IT INCLUDES A STATOR PROVIDED WITH POLAR SYSTEMS AND A ROTOR WITH THE ROTATION WHICH IS ASSOCIATED WITH AN AXIAL DISPLACEMENT, THIS STATOR AND THIS ROTOR BEING MAGNETICALLY TAKEN BY THE INTERMEDIARY PRECISION THREADING, AND THE LIFT TABLE IS EQUIPPED WITH A DEVICE PREVENTING IT FROM TURNING. C. THE INVENTION APPLIES MAINLY TO LIFT TABLES, FOR EXAMPLE TO REALIZE ADJUSTING SYSTEMS AND, AMONG OTHERS, AUTOMATIC EQUIPMENT FOR MANUFACTURING SEMICONDUCTORS.
