Title:
VIBRATION ISOLATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/030748
Kind Code:
A1
Abstract:
 The aim of this invention is to suppress the resonance frequency of rigid body resonance resulting from vibration in the axial direction. This vibration isolation device (60) comprises an outer frame part (61), an inner member (62), an intermediate ring (63), and an elastic vibration isolation main body (64). The outer frame part (61) and intermediate ring (63) are joined together with the elastic vibration isolation main body (64). An inner gap (65) is provided between the intermediate ring (63) and the inner member (62) so as to surround the inner member (62), and the intermediate ring (63) is able to move in an axial direction with respect to the inner member (62). Vibration in the mounting axis direction pushes the outer frame part (61), intermediate ring (63) and elastic vibration isolation main body (64) together, moving in an axial direction with respect to the inner member (62), with the result that spring in the mounting axis direction becomes weaker, and the resonance frequency of the rigid body resonance resonance in the mounting axis direction falls.
