ROTARY MACHINE MAGNETIC BEARING ASSEMBLY AND TURBOMACHINE THEREWITH Russian patent published in 2018 - IPC F16C32/04 F16C37/00 F16C39/06 

FIELD: machine building.

SUBSTANCE: invention relates to bearings, in particular to magnetic bearings used in rotary machines having a rotor. Magnetic bearing assembly (10) for the rotary machine has rotary shaft (12), wherein said assembly comprises stator magnetic conductor (18) attached to fixed support member (26) and comprising at least one ferromagnetic material element (22) and at least one coil (20), wherein said ferromagnetic member and said at least one coil are placed in protective annular body (24), leaving surface (22a) of rotation of said ferromagnetic member (22) and rotation surface (20a) of said at least one coil (20) exposed. Magnetic bearing assembly (10) comprises thrust ring (16) attached to rotor shaft (12) and radially extending to stator magnetic conductor (18) with its radial part (16b). Radial portion (16b) faces exposed surfaces (20a, 22a) of said ferromagnetic element (22) and said at least one coil (20). Thrust ring (16) has at least one flow channel (30, 32).

EFFECT: creation of a magnetic bearing assembly in which the cooling flow is increased, the flow channels facilitating the injection of fluid flow, increasing the cooling of the active magnetic bearing, and the magnetic bearing is thus provided with internal ventilation.
