FIELD: machine building.
SUBSTANCE: invention relates to turbomachinery, particularly, to design intershaft turbomachine rotor supports. Turbomachine rotor support contains roller bearing and mounting ring at the inner ring roller bearing. Outer ring roller bearing is installed in shaft gear central bevel gear, and the inner ring is fixed on the turbine shaft in axial direction. Set ring has coefficient of thermal expansion, greater than that of the turbine shaft is installed on the latter and is fixed on it in axial direction. Inner diameter of the mounting ring is made with eccentricity in relation to its outer diameter, and turbine shaft axis coincides with axis of roller bearing.
EFFECT: invention enables to avoid slipping of inter-shaft roller bearing without radial displacement unit central bevel gear.
