Abstract

L'invention concerne une paire de rotors pour machine à rotors à vis. La rainure entre les saillies des filets du rotor auxiliaire présente, en section transversale, les segments suivants de profils: une cycloïde 1, une développante 2 dont le cercle de base est situé à l'intérieur du cercle primitif 10, une conchoïde 3 d'un cercle situé à l'extérieur du cercle primitif 10, un arc de cercle 4 dont le centre est situé sur le cercle primitif 10, une enveloppante 5 d'une ellipse disposée sur la saillie du rotor principal, dont le centre est situé sur le cercle primitif du rotor principal 11, un arc de cercle 6 à courbure concave, un arc de cercle 7 à courbure convexe. La forme de la saillie du filet du rotor principal est constituée de segments de profils associés de façon correspondante Applications : compresseurs.
