  • Vibration isolator with displacement structure
    Patent number: 9754711
    Abstract: A vibration isolator is provided including a base structure, a load structure, a displacement structure and at least one vertical open gap formed by opposing and substantially parallel walls of the base structure and the load structure. The opposing walls being at least partly covered by respective arrays of permanent magnets, neighboring magnets in the arrays having alternating magnetization directions, an arrangement of the permanent magnets in the arrays being such that a gravitational force on the load structure is substantially compensated by a net magnetic force of the base structure on the load structure. The displacement structure relatively displaces arrays of permanent magnets of the opposing walls with respect to each along the gap for adjusting a load capacity of the vibration isolator.

  • VIBRATION ISOLATOR WITH DISPLACEMENT STRUCTURE
    Publication number: 20160099094
    Abstract: A vibration isolator is provided comprising a base structure, a load structure, a displacement structure and at least one vertical air gap formed by opposing and substantially parallel walls of the base structure and the load structure. The opposing walls being at least partly covered by respective arrays of permanent magnets, neighboring magnets in the arrays having alternating magnetization directions, an arrangement of the permanent magnets in the arrays being such that a gravitational force on the load structure is substantially compensated by a net magnetic force of the base structure on the load structure. The displacement structure relatively displaces arrays of permanent magnets of the opposing walls with respect to each along the air gap for adjusting a load capacity of the vibration isolator.
