ROTARY BODY SUPPORT DEVICE
Document Type and Number:
Japanese Patent JP2010071310
Kind Code:
A
Abstract:
To provide a rotary body support device capable of restraining vibration of a rotary body, when a rotational frequency of the rotary body passes through a resonance frequency of the rotary body.
A control means 34 controls a support rigidity changing means 22 so that the rotational frequency (f) of the rotary body 18 passes through the resonance frequency fn of the rotary body 18, while reducing the resonance frequency fn of the rotary body 18 by reducing support rigidity by a first bearing 13 by the support rigidity changing means 22, when increasing a rotating speed of the rotary body 18 by a rotating speed adjusting means 31.
