TURBINE ASSEMBLY Russian patent published in 2013 - IPC F01D1/14 F02C7/06 

FIELD: machine building.

SUBSTANCE: turbine assembly comprising at least one first and one second rotor wheels, a shaft and a bearing system. Back surfaces of rotor wheels are turned to each other. Radial rotor wheels are installed on the rotor shaft. In the zone of both radial rotor wheels there installed are thrust bearings respectively with one rotor bearing half and one stator bearing half. The rotor bearing half is placed on the back surface of conjugated radial rotor wheel. The first radial rotor wheel is made as one-piece. The second radial rotor wheel capable of being demounted is connected to the rotor shaft. The rotor shaft at the outlet from the first radial rotor wheel in the direction of the second radial rotor wheel is tapering or has constant diameter.

EFFECT: invention allows for the simplification of rotor wheel mounting and demounting as well as for the improvement of maintenance possibilities.
