FIELD: engines and pumps.
SUBSTANCE: claimed engine comprises the shafts (5) and (12) of the blower (2) and low-pressure turbine (11) engaged by involute splines (13). Coupling screw (14) is fitted inside the blower shaft (5) on spherical rings (16) and (17) and screwed in screw sleeve (15). Sleeve (15) is fitted in the low-pressure turbine shaft (12) by spherical ring (19) and locked by splines (20) of equalising sleeve (21) in circumferential direction. Sleeve (21) is fitted by its outer axial ribs (22) in circular groove (23) of the blower shaft (5) and locked relative to axial ledges (28) at its extension (24) in axial and radial directions by radial ledges (25) at radial ribs (26) and by lock ring (27) to be fitted in the shaft circular groove (23) in slits (29) between axial ribs (22) of sleeve (21) of equalising weights (30). Sidewalls (33) and (34) of slits (29) are parallel.
EFFECT: higher engine reliability owing to ruled out blower shaft unbalance and bending stresses in tightening screw.
