FIELD: machine building.
SUBSTANCE: invention relates to supporting devices and bearings with permanent magnets and can be used mainly for rotating shafts and rotors of machines with little varying and constant external axial loads, such as fans, turbo compressors, electric motors, flywheels (energy storage), gyros, etc. Magnetic bearing assembly contains rotor (1, 2) with a supporting and output ends, stator (3), two radial magnetic supports of rotor with ring magnets (6, 8 and 7, 9) and axial stop (5) acting on the end of supporting end rotor (1, 2). Each radial magnetic bearing contains at least two ring magnets having the same dimensions and the same direction of axial magnetization. Magnets of each support (6, 8 and 7, 9) interact in the mode of attraction through an axial gap. Stator magnets (8 and 9) are placed between rotor magnets (6 and 7). Rotor is displaced axially in the direction opposite to the direction of external axial load (F) by means of stop (5), with the formation of different axial clearances (s1 and s2) in the magnetic supports.
EFFECT: technical result: simplified design of the magnetic support and reduction of friction.
