<p>Magnetic clutch for the transmission of tightening torque that comprises a first shaft (2) integral to a casing (3) in whose interior there is a second shaft (4) coaxial to the first shaft (2) that is fixed to the casing (3), where said shafts (2, 4) are engaged together by magnetic attraction to transmit tightening torque, said clutch (1) comprises a first magnetic assembly (6), linked to one of the shafts (2, 4), formed by a first group of magnets (7) of high magnetic coercivity and a second magnetic assembly (8), linked to the remaining shaft (2, 4), formed by a magnet (9) of low magnetic coercivity and by a second group of magnets (10) of high magnetic coercivity adjacent in axial direction to the magnet (9), where the first magnetic assembly (6) and the second magnetic assembly (8) present a facing surface (F) in radial direction.</p> |
