GAS TURBINE

WIPO Patent Application WO/2023/134176

A1

A gas turbine, comprising a rotating shaft (100), a compressor (200), a turbine (300), and a combustion chamber (400). The compressor (200) and the turbine (300) are sleeved on the rotating shaft (100); a guide vane assembly (600) is provided at an outlet end of the combustion chamber (400); a bearing and a bearing seat assembly are arranged on the rotating shaft (100); the bearing is located in the bearing seat assembly; the guide blade assembly (600) is connected to the bearing seat assembly by means of a heat conduction component (800). According to the gas turbine, the heat conduction component (800) is provided between the outlet end of the combustion chamber and the bearing seat which are conventionally in lap joint, and heat at the outlet of the combustion chamber is conducted to the part of the bearing seat distant from the bearing, so that heat delivered to the bearing seat can be more uniformly distributed in the bearing seat, and the bearing and the bearing seat near the bearing are uniformly heated; thus, the deformation is uniform, local high temperature at the bearing is avoided, and defects such as gas leakage, coaxiality change, uneven gas film, and stuck rotating shaft caused by irregular deformation of the gas bearing due to uneven heating are overcome.
