Abstract: 본 발명에 따른 공기 포일 베어링은, 회전축(110)을 둘러싸도록 설치되는 베어링 하우징(160); 회전축(110)과 하우징(160) 사이에 회전축(110)을 둘러싸도록 회전축(100)에 소정간격 이격되게 설치되는 탑포일(130); 및 탑포일(130)과 하우징 (160) 사이에 끼이도록 설치되며 탑포일(130)에 눌려 탄성압축 변형이 가능하도록 설치되는 범프포일(140); 을 포함하여 이루어지되, 탑포일(130)과 범프포일(140)의 끝단은 하우징(160)의 내면에 고정되어 고정단을 이루고 그 반대편의 선단은 하우징(160)의 내면을 따라 환형으로 연장되어 상기 끝단과 소정간격 이격되면서 자유단을 이루며, 하우징(160)에는 상기 고정단과 자유단 사이에 냉각용 공기(181)가 공급될 수 있도록 냉각공기 주입구(180)가 형성되는 것을 특징으로 한다. 본 발명에 의하면, 공기 포일 베어링의 냉각효율이 좋아지므로 초고속 회전체를 지지하는데 더욱 효과적이게 되며, 공기가 외부에서 지속적으로 공급되므로 공기 윤활막(120)이 더욱 진동 완충 및 윤활제 역할을 제대로 수행할 수 있게 된다. 범프포일(140) 대신에 탄성 압축변형될 수 있는 다른 형태의 포일이 설치되는 경우에도 본 발명이 적용될 수 있음은 당연하다.

Abstract: The present invention relates to a micro gas turbine with a compact structure. More specifically, a sub journal bearing is placed between a thrust collar and a wheel of a compressor which means the bearing is placed around the thrust bearing at a compressor so that the whole length and weight of a rotator are reduced to form the compact structure. A pair of main journal bearings separated from each other at a certain distance is placed between a hollow shaft and a sleeve. The main journal bearings fully support a shaft between the compressor and turbine wherein dynamic pressure is heavily applied caused by rotation in order to maximize safety. For the purpose, the present invention comprises a turbine wheel; a tie shaft which one end part is connected to the turbine wheel; a compressor wheel which is separated from the turbine wheel to be inserted into the tie shaft; a thrust rotor separated from the compressor wheel to be fixed to the end part of the tie shaft; the thrust collar placed on a part of the outer surface of the thrust rotor; and the sub journal bearing equipped between the thrust collar and the compressor wheel.

Abstract: PURPOSE: A turbocharger generator is provided to utilize a floating ring bearing as a rotor for power generation not directly using a turbine shaft as the rotor, thereby stably generating power aided by the buffering effect of oil injected between the turbine shaft and the floating ring bearing. CONSTITUTION: A turbocharger generator comprises a turbine wheel(12), a compressor wheel(22), a turbine shaft(30), a floating ring bearing rotor(140), and a stator(150). The turbine wheel is rotated by the flow of exhaust gas discharged from an engine. The compressor wheel absorbs air by rotating along with the turbine wheel and supplies the air to a cylinder of the engine. The turbine shaft connects the turbine wheel to the compressor wheel for delivering the rotational force of the turbine wheel to the compressor wheel. The floating ring bearing rotor is installed surrounding the turbine shaft and made of a permanent magnet. The stator wound up with coils is installed in the circumference of the rotor to be separated from the rotor a certain distance apart. An oil inlet(141) is formed in the floating ring bearing rotor for oil to be injected between the turbine shaft and the floating ring bearing.
