Vibration eliminating apparatus for eliminating vibration of installation floor.

摘要

A vibration eliminating apparatus for eliminating vibration by suspending a floor board from an installation floor. A supporting electromagnet is provided to the installation floor in order to suspend a magnetic member fixed to the floor board by a magnetic force. The magnetic member is provided with a thin magnetic pole through a non-magnetic member and a control electromagnet having a yoke located in the proximity to the thin magnetic pole is provided to control a horizontal position of the floor board. A vibration detector is provided to detect vibration of the floor board and a vibration monitor is used to decide whether vibration detected by the vibration detector is within an allowable range of a machine mounted on the floor board or not and output an operation enable signal only when vibration is within the allowable range.
