发明名称 ADJUSTMENT DEVICE OF ALIGNMENT OF SYNCHRONISING CONTROL RING OF ROTATING BLADES OF GAS-TURBINE ENGINE, AND GAS-TURBINE ENGINE
摘要 FIELD: engines and pumps. ^ SUBSTANCE: adjustment device of alignment of control ring of rotating blades of gas-turbine engine relative to cylindrical casing of crankcase includes control ring containing multiple threaded holes made in radial direction and multiple holders of blocks, each of which includes threaded bar screwed into one of threaded holes of the ring. On inner end of each block holder there installed is the block intended to come into contact with cylindrical casing. In addition, control ring includes multiple slots having tangential direction and passing through the ring in radial direction. Each slot is interconnected with one of threaded holes of the ring. Device has also compression means of each of the slots in longitudinal direction in order to lock the position of block holders. Other invention of the group refers to gas-turbine engine containing the above adjustment device of alignment of control ring of rotating blades. ^ EFFECT: inventions allow simplifying the alignment device of control ring and improving its reliability, and accurate alignment of control ring of rotating blades is provided. ^ 5 cl, 5 dwg
