FIELD: machine building.
SUBSTANCE: invention relates to bearing devices cooled by fluid medium, in particular, to devices containing magnetic thrust bearing cooled by fluid medium flow. Magnetic bearing device (1) contains thrust bearing flywheel (2) installed with possibility of rotation, for magnetic interaction with at least one fixed axial stop (3, 4) and passage for cooling fluid medium, intended for supply of flow (31) to flywheel (2) in direction (F) of flow (31), passing in essentially radial plane relative to axis (XX') of rotation of flywheel (2). Device (1) comprises at least one guide element (7) for fluid flow, through which passes at least one channel (20), opening near peripheral circumferential surface (24) of flywheel (2) and configured to feed flow (31) to flywheel (2) in direction of propagation perpendicular or inclined relative to local radial direction (Rad (M)) of flywheel (2).
EFFECT: technical result is achieved reduction of internal friction of fluid medium created by cooling flow, so, amount of heat to be removed is reduced, as well as cooling fluid flow rate required to ensure required temperature of magnetic bearing device.
