FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: invention relates to transmission connecting rotors of turbine and compressor. Proposed device contains intermediate shaft, whose tail piece is fitted in turbine shaft by splines through splined sleeve, and front piece is fitted in compressor shaft. Alignment ring is fitted in ring groove on intermediate shaft tail piece on outer diameter of splines of turbine shaft.
EFFECT: improved reliability of roller bearing of turbine, reduced air leakage through seals owing to improved fastening of intermediate shaft on shaft of turbine.
