<p>The invention relates to a multiple axial coupling, provided with permanent magnets for transmitting the motion between a leading driving shaft of an actuation machine and the driven shaft of a working machine such as the natural gas turbocompressor. According to the invention, the coupling comprises some end armatures (1a and 1b) and some intermediary armatures (1c and1d) provided with some end and intermediary magnets (2a and 2b), axially magnetized and in heteropolar arrangement on the circumference, the armatures (1a, 1b, 1c and 1d) being alternatively stiffened to an outer non-ferromagnetic housing (3) and to an inner shaft (4) which, at their turn, by means of a connection piece (5), are stiffened with one of the two ends of the leading shaft and the driven shaft respectively, the two end armatures ( 1a and 1b) which act also as ferromagnetic yokes for closing the magnetic circuits, both being stiffened by a housing (3).</p> |
