Vibration-proofing device.

摘要

The present invention relates to a vibration-proofing device which supports an upper structure (11), on a lower structure (12), to allow the upper structure (11) to swing, thereby isolating earthquakes, traffic vibrations and vibrations from the equipment installed in another room so as to protect the upper structure (11) from vibrations. An object of the Invention is to provide a bearing type of vibration-proofing device which absorbs not only horizontal but also vertical components of vibrations. The invention provides an arrangement wherein interposed between upper (11) and lower (12) structures are rolling bodies for horizontally supporting the upper structure for swing movement, the device being characterized in that the rolling bodies (17,18) are in the from of cylindrical rollers and elastomeric bodies (14) are interposed between the cylindrical rollers (17,18) and the upper (11) and lower (12) structures. In the present invention, it is desirable that the cylindrical rollers (17,18) be stacked in n rows and that these rows of cylindrical rollers form an angle of 180 DEG /n. Further, it is more desirable that air spring (28) or coil spring (26) means be disposed vertically of the cylindrical rollers and that a plurality of taper rollers be radially arranged in a horizontal plane vertically of the cylindrical rollers (17,18). <IMAGE>
