Claims

[Scope of utility model registration request]

A bearing device for a rotating machine that pivotally supports a rotating shaft whose rotation speed changes, wherein a bearing portion of the device includes a first bearing that directly supports the rotating shaft, and an outer side of the first bearing that surrounds the first bearing. and a second bearing that rotatably holds the first bearing inside and pivotally supports the rotating shaft via the first bearing, and the rotating shaft and the second bearing are configured to have a double structure. fixing means that can freely fix or release each other between the first bearing and the stand holding the first bearing and the second bearing; A bearing device for a rotating machine, characterized in that the former is opened and the latter is fixed when the rotating shaft is rotating at high speed, and the former is fixed and the latter is released when the rotating shaft is rotating at low speed. .
