Gas turbine containing an additional combustion gas compressor
A gas turbine containing an additional combustion gas compressor and a gearing drive which, on the one hand, is rotatably connected by means of a rigid coupling and an axial bearing with the gas turbine and, on the other hand, is rotatably connected by means of a further rigid coupling with the combustion gas compressor. Furthermore, the gearing drive serves to drive a generator by means of a power take-off shaft. The gears of the gearing drive possess helical teeth. For thrust compensation purposes the drive gear of the gearing drive is provided with pressure plates, and the helical teeth of the gears are designed such that a force acting upon the pressure plates and resulting from the thrust of the combustion gas compressor is reduced by the axial component of the helical teeth.
