Abstract
공기 냉각 장치 내부에 구비된 베어링의 마찰열을 냉각하는 냉각수단의 구조가 개선된 공기 냉각 장치에 관해 개시한다. 본원의 베어링 냉각수단은, 터빈 케이스에 적어도 하나의 공기유입관이 마련되며, 그 공기 유입관과 연통되어 베어링 주위에 형성된 공기의 유로가 구비되어 된 것으로써, 이와 같이 터빈 케이스에 유입관을 형성시킴으로써, 흡입되는 공기의 유량을 회전속도와 관계없이 일정하게 유지하여 냉각효율을 확보할 수 있고, 터빈 디스크에 유입관을 형성하지 않음으로써, 강성이 저하되는 문제점을 방지할 수 있다.An air cooling apparatus improved in structure of a cooling means for cooling frictional heat of a bearing provided in an air cooling apparatus is disclosed. The bearing cooling means of the present invention is characterized in that at least one air inflow pipe is provided in the turbine case and an air flow path formed around the bearing is provided in communication with the air inflow pipe so that an inflow pipe is formed in the turbine case The cooling efficiency can be maintained by keeping the flow rate of the air sucked constant regardless of the rotational speed and the problem that the stiffness is lowered can be prevented by not forming the inlet pipe in the turbine disk.
