BEARING ASSEMBLY Russian patent published in 2016 - IPC F16C32/04 F16C39/06 

FIELD: energy.

SUBSTANCE: invention relates to power machines, made in ungreased implement containing low and high pressure cavities (compressor machines, aircraft engines, pumps, etc.). Bearing assembly comprises shaft (2), installed in bearing (2), chamber (3) in bearing case, holes made in inserts (4) of bearing, and permanent magnet (5) installed between inserts (4). Bearing is made ungreased of polymer material. Bearing assembly includes cavities of high and low pressure and at least more than one unit of unloading is made. Unit of unloading is formed by chamber (3), magnet (5), holes (14) in insert (4) of bearing located diametrically to chamber (3), and additionally introduced flexible element (6), controling throttle element (7) and channels (8, 9). High and low pressure cavities and units of unloading are braced with channels (8, 9).

EFFECT: technical result is increased resource of power machine by unloading of radial bearings at variable in time loading forces as in magnitude and direction in case of change of operating mode of power machine or its orientation in space.
