SUPPORT OF THE RADIAL BEARING OF THE ELECTRIC MOTOR OF THE BLADE PUMP Russian patent published in 2023 - IPC F04D29/46 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the bearing supports of electric motors of pumping units and can be used at nuclear power plants in the main circulation pumping units of the primary coolant circuit of a nuclear power plant. The support of the radial bearing of the blade pump consists of a base ring (11), which has flat inclined surfaces (20); a radial bearing (6), which is installed in the inner bore (14) of the base ring (11) and bolted (12) to it; a housing (4) with a support surface (15) along which the base ring (11) moves together with the radial bearing (6) when adjusting the adjustment wedges (18), the flat inclined surfaces (20) of which are mated with the reciprocal flat inclined surfaces (13) of the base ring (11), which serve to move the base ring (11) with a radial bearing (6) on the support surface (15) of the housing (4) by means of adjusting bolts (16) and release bolts (17). After adjustment, the base ring (11) is fixed to the housing (4) using pins (10).

EFFECT: invention is aimed at reducing the repair time of the electric motor of the main circulation pumping unit.
