TURBO-GENERATOR Russian patent published in 2010 - IPC F01D15/10 

FIELD: machine building.

SUBSTANCE: turbo-generator consists of case with cover, of rotor and of stator of electro-generator. The case with cover are tightened with fasteners and have a common internal cavity wherein there is installed a turbine wheel mounted of a shaft. The case is equipped with an inlet branch for supply of working medium into the turbine wheel. An output cavity communicated with the output branch for withdrawal of working medium is made on the side of withdrawal of working medium from the turbine wheel. The shaft is installed on two ball bearings located on opposite sides of the turbine wheel. One of the ball bearings is installed in the case, while another - in its cover. From the end facing the input branch the shaft has a blind port connected with a working channel of the turbine wheel on the side of the bottom of the blind port. The inlet branch of the case has a cylinder head introduced into the blind port of the shaft; the latter has a labyrinth packing enveloping fitting of the case. The rotor of electro-generator is made as a cartridge with an orifice in the bottom. The turbine wheel is equipped with a hub where the rotor is put on through an orifice in the cartridge bottom; the rotor is fixed relative to the turbine wheel and concentrically envelopes the stator of the electro-generator stationary fixed in the cavity of the case on its cover.

EFFECT: increased reliability of turbo-generator operation and improved weight and dimension characteristics.
