Abstract

본 발명은 회전축을 자력에 의해 비접촉회전하도록 지지하는 자기베어링을 구비하는 회전축 지지장치에 관한 것으로서, 특히 자기베어링의 정지시 또는 비상시에 회전축이 접촉지지되도록 하기 위한 수단을 구비한 회전축 지지장치에 관한 것이다.The present invention relates to a rotary shaft support device having a magnetic bearing for supporting the rotary shaft in a non-contact rotation by a magnetic force, and more particularly to a rotary shaft support device provided with means for allowing the rotary shaft to be in contact when the magnetic bearing is stopped or in an emergency. will be.

본 발명 회전축 지지장치는 자기 베어링에 의해 비접촉회전하는 회전축과 정지시 또는 비상시에 그 회전축을 접촉 지지하도록 된 부재를 구비하며, 상기 회전축과 상기 부재와의 간격을 조절할 수 있도록 되어 있으므로, 회전축의 회전시 진동허용범위를 최대로 할 수 있으며, 정지시나 비상시에 진동 및 충격을 방지하여 자기베어링에 손상을 가하는 것을 방지할 수 있다.The rotary shaft support device of the present invention includes a member which is in contact with a rotating shaft which is in non-contact rotation by a magnetic bearing and the rotating shaft is in contact with the rotating shaft at the time of stop or emergency, and the distance between the rotating shaft and the member can be adjusted so that the rotating shaft is rotated. Vibration allowable range can be maximized and vibration and shock can be prevented during stop or emergency to prevent damage to magnetic bearings.
