Claims

[Scope of utility model registration request]

A bearing box that supports an outer sleeve rotatably supporting the rotor via a rolling bearing via a radial oil film damper, and a bearing box that surrounds the rotor between the outer sleeve and the fixed part so as to support the center axis of the rotor. In a vibration damping structure for a high-speed rolling bearing system having a centering spring biased to match the center axis of the bearing, vibration in a thrust direction of the centering spring is suppressed between the centering spring and the fixed part. A vibration damping structure for a high-speed rolling bearing system, characterized by having a thrust vibration damping means that vibrates.
