Title:
VIBRATION-PROOF DEVICE AND VIBRATION-PROOF ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/163596
Kind Code:
A1
Abstract:
This vibration-proof device (20) is provided with a coil spring (24), a first inclination part (21) and a second inclination part (22). The coil spring (24) is disposed between the hull (2) of a ship and a propulsion engine (4), and absorbs vibrations from the propulsion engine (4). The first inclination part (21) has a first inclined surface (21a) along a rake angle, is disposed between the hull (2) and the coil spring (24), and is inclined relative to the hull (2) so that a hull (2)-side attachment surface of the coil spring (24) approaches a horizontal plane. The second inclination part (22) has a second inclined surface (22a) along the rake angle, is disposed between the propulsion engine (4) and the coil spring (24), and is inclined relative to the propulsion engine (4) so that a propulsion engine (4)-side attachment surface of the coil spring (24) approaches the horizontal plane.
