<p>An hysteresis ring comprises a jacket (2) made of hard magnetic alloy radially held and centered about a shaft by a ring disc-like bottom part (1) which may be made of a non magnetic alloy. A joint and clamp connection, achieved by a rolled edge (3) secured to a collar (5) of the jacket (2) during assembly, enables to obtain a butt-end axial connection of both hysteresis ring elements capable of withstanding high loads and enabling particularly to save hard magnetic alloy as well as production devices. The jacket (2) is rapidly, easily and economically produced by using a minimum of machine tools and with the most varied dimensions, either from pipes or from cut material bands which are rolled and riveted, rebated or welded in the longitudinal direction.</p> |
