The present invention relates to a passive vibration isolation device for broadband suppression of vibrations. The device preferably comprises either a vertical spring filter (206, 208), a horizontal spring filter (204), or a combination of the two. The vertical spring filter may comprise any number of Belleville (208) or ZK (700) washers, stacked in series, in parallel, or any combination thereof. ZK washers are washers which comprise multiple integral concentric rings of varying conicity. The device further may optionally comprise a screw (1416), belt (2408), or similar device for adjusting the aspect ratio of the vertical spring. The device further may optionally comprise a screw (212), or similar device for adjusting the static load placed on the vertical spring. The horizontal spring filter may comprise any number of bearings retained within a conical raceway (222, 224) disposed between two cylindrical plates (114). The vibration isolation device then may be placed beneath a machine, or a platform supporting a machine, to isolate vibrations otherwise transmissible from the floor to the machine or vice versa. |
