FIELD: engines and pumps.
SUBSTANCE: steam turbine includes steam outlet connection pipe for directing the waste steam, bearing for supporting the turbine shaft, as well as at least two spacers for the bearing by means of which the bearing is fixed on steam outlet connection pipe. Each of the spacers has cooling hollow space located in it and intended for the cooling medium passage. Cooling hollow spaces of spacers for the bearing are attached via fluid medium through the closed connecting hollow space in the area of the shaft bearing so that there provided is the possibility of suction of ambient air as cooling medium through the connecting hollow space and outlet through the other spacer for the bearing.
EFFECT: invention allows increasing steam turbine efficiency.
