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.The invention relates to a pair of rotors for a screw rotor machine. The groove between the projections of the threads of the auxiliary rotor has, in cross section, the following profile segments: a cycloid 1, an involute 2 whose base circle is located inside the pitch circle 10, a conchoid 3 of a circle located outside the pitch circle 10, an arc of a circle 4 whose center is located on the pitch circle 10, an enveloping 5 of an ellipse arranged on the projection of the main rotor, the center of which is located on the pitch circle of the main rotor 11, a circular arc 6 with concave curvature, a circular arc 7 with convex curvature. The main rotor thread protrusion shape consists of correspondingly associated profile segments Applications: Compressors.
