FIELD: engines and pumps.
SUBSTANCE: countershaft is arranged between low-pressure compressor rotor shaft and low-pressure turbine shaft and splined therewith tangentially while axially it is coupled by coupling bolt and pipe, respectively. Note here that coupling pipe is locked tangentially by coupling pipe splines. Said pipe locks tangentially said coupling bolt by splines and is splined with low-pressure compressor rotor. Note here that spring is arranged between coupling bolt and lock pipe and aligned with the latter. Besides, cavity is made at stator section confined by sleeve and axially displacing piston. Said cavity communicated with hydraulic system delivery side via channel with bypass line. Note also that said piston is locked tangentially relative to sleeves by splines. Note that spring is arranged between said sleeve and piston and aligned with the latter. Besides, near tend surface of lock pipe and piston are tapered to make the gap there between. Bypass valve is connected with digital control system computer.
EFFECT: preservation is shafts alignment at worst-case situation.
