Abstract

PURPOSE:To heighten safety and reliability by localizing damage due to excessive vibration at a protective bearing portion of fragile structure more than other portions, and cushioning a rotor inclined due to damage at another protective bearing portion. CONSTITUTION:A protective shaft 14 is mounted on an upper shaft end 7a of a fly wheel 1. The protective shaft 14 is fored of Al, plastics, or the like and is easily replaced. The second protective bearing 15 formed of soft material such as white metal is disposed on the outer peripheral portion of a magnetic bearing 8 on the rotation side, and is fixed to the interior 13 of a receptacle through a bearing support 16. When excessive vibration is generated, the protective shaft is brought into contact with a protective bearing 11 to be broken, so that the other rotors such as the upper shaft 7 and so on are kept from damage. After that, the rotor is kept from damage by bringing the second protective bearing 15 into contact with the magnetic bearing 8 on the rotation side and rotating same.
