<p>The invention relates to a device for dynamic equilibration with magnetic coupling, meant for installations of rotors dynamic equilibration. According to the invention, the said device consists of a driving rotary assembly, comprising a hollow shaft (1), supported by two fixed radial bearings (2 and 3), integral with a casing (4), two lateral flanges (5 and 6), with the role of shields supporting some permanent magnets (7), placed circularly, with axial direction of magnetization, in heteropolar structure which comprises an interior central shaft (8) supported in fixed position, according to the axial direction, in relation to the driving rotary assembly, by means of a spherical joint (9) placed inside the hollow shaft (1) and supported on a threshold thereof, the central shaft (8) being integral with an intermediary flange (10) interposed between the flanges (5 and 6) crossed by the permanent magnets (11) identical as diameter and number as in the driving assembly, also circularly placed, with axial magnetization direction in heteropolar structure, facing the magnets (7) on the flanges (5 and 6) and by which there delimits two axial air gaps lateral to the flange (10), at whose level there is produced the phenomenon of magnetic coupling.</p> |
