A fluid bearing magnetic or ferromagnetic - fluid, the manufacture of magnetization of a structure ferromagnetic cylindrical and permanent magnet comprising such a structure

摘要

The invention relates to a cylindrical bearing on the magnetic fluid or ferro -. & br / & this bearing comprises a structure 10 axially traversed by a bore 20 through which passes a shaft 12. A magnetic fluid or ferro - fluid 14 is placed in the space between the bearing and the shaft 12, and the structure 10 of the bearing, made of ferromagnetic material, is magnetized in a manner that its internal magnetization is oriented radially with respect to the axis of the bore 20. & br / field of application: bearings for shafts. & br / (see appended drawing in bopi) & br / & & br /
