FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to electric machines of vertical type, intended for water supply systems of nuclear power plants and using a closed lubrication system. Oil bath of electric machine is formed by cylindrical wall (1), bottom (2), to which stiffness ribs (3) are connected. Oil bath comprises baffle (5) to accommodate shaft (4), thrust bearing (6) resting on support disc (7), which is fixed on stiffness ribs (3), and cooler (8). Thrust bearing (6) comprises bushing (9) connected to rotating disc 10, with which plain bearing (11) interacts. Oil bath is additionally equipped with female support disc (7) perforated enclosure (17), outside of which there is cooler (8) made in the form of pipes (20) coiled and laid on vertical posts (23) placed around support disk (8).
EFFECT: higher reliability.
