Title:
VIBRATION DAMPING DEVICE OF BEARING
Document Type and Number:
Japanese Patent JP2019157871
Kind Code:
A
Abstract:
To achieve stable vibration damping performance by minimizing influence by abrasion powder caused by collision of spherical particles in a vibration damping device applying the spherical particles as a damper element.SOLUTION: In a vibration damping device 1 of a bearing provided with an inner cylinder 4 which can displace in a radial direction with respect to an apparatus housing 3, and a storage space 7 disposed between an outer peripheral face of the inner cylinder 4 and an inner peripheral face of the apparatus housing 3, and filled with spherical particles 6 causing damping action by vibrational friction, at least one or more magnetic traps 15 are inserted and disposed in the storage space 7 filled with the spherical particles 6, from an apparatus housing 3 side.SELECTED DRAWING: Figure 1
