Title:
ACTIVE VIBRATION-DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/142801
Kind Code:
A1
Abstract:
Provided is an active vibration-damping device having a novel structure, the device making it possible to avoid situations in which an installation position on an object to undergo vibration-damping is completely covered and becomes inaccessible, and also to easily realize a variety of attachment modes on the object to undergo damping. Provided is an active vibration-damping device 160 in which an axial-direction vibration mechanism 12 brought about by electromagnetic force is provided between a mass member 48 and an inner shaft member 190 attached to a vibration absorption object 14, the mass member 48 being installed so as to be positioned on the outer periphery of the inner shaft member 190 and so as to be capable of relative displacement in the axial direction, wherein: the inner shaft member 190 is formed as a hollow structure having an inner hole 194 extending in the axial direction; the inner hole 194 is opened at least at one axial-direction end; and a securing part is configured, with respect to the object 14 to undergo vibration damping of the inner shaft member 190, in the inner hole 194 of the inner shaft member 190 and/or a flange part 146 that projects toward the inner periphery or outer periphery from the inner shaft member 190.
