Abstract

The invention provides an auxiliary force transmission casing structure of a gas turbine. The casing structure is arranged between a turbine outer ring and a low-pressure turbine rotor outer casing and comprises a left flange edge, a right flange edge and a Y-shaped support structure. A left flange edge and a right flange edge with seam allowance positioning are cooperated and connected with the turbine outer ring and the low-pressure rotor outer casing. By using the auxiliary force transmission casing of the gas turbine, a function of transmitting a force from the low-pressure turbine rotor outer casing to the turbine outer ring is achieved, and at the same time, when a temperature changes, buffering is added for deformation of the auxiliary force transmission casing, a relative positionbetween the low-pressure turbine rotor outer casing and the turbine outer ring is guaranteed, and a problem that the casing deforms unharmoniously due to a temperature difference between an inner ringand an outer ring and the like is solved. The auxiliary force transmission casing of the gas turbine is simple and compact in structure, easy to machine and good for reducing manufacturing cost of anaero-engine.

Description

technical field [0001] The invention belongs to the field of gas turbine / aeroengine, and relates to an auxiliary power transmission case structure of a gas turbine, more specifically, a simple, compact and easy-to-process power transmission device is used between the turbine outer ring and the low-pressure turbine rotor outer case The casing structure, while realizing the force transmission function, solves the incongruous effect of casing deformation caused by the temperature difference between the inner and outer rings, etc., and ensures the relative position between the outer casing of the low-pressure turbine rotor and the outer ring of the turbine. Background technique [0002] An aero engine is generally composed of an intake port, a compressor, a combustion chamber, a turbine and an exhaust nozzle. Among them, the turbine converts the thermal energy of high-temperature and high-pressure gas into mechanical work to provide engine power and compression work of the compr...
