Claims19
A rotary system (200) for reducing vibration in said rotary system (200) comprising a rotational element (110), wherein the rotational element comprises a chamber (120) having a fulcrum on a rotational axis (150) of said rotational element (110) comprising a circumferential balancing area (130) and being partially filled with an amount of a composition (240) comprising an amount of a thixotropic balancing substance and an amount of hydrophobic particles distributed in said amount of said thixotropic balancing substance,
- wherein said hydrophobic particles have
- surfaces comprising fluorocarbon,
- cores comprising a fluorocarbon, a silicone, a metal, or carbon, or
- a specific surface area in the range from approximately 2 m2/g to approximately 20 m2/g.
A method of reducing vibration in a rotary system (200) comprising:
- distributing an amount of a composition (240) comprising an amount of a thixotropic balancing substance and an amount of hydrophobic particles distributed in said amount of said thixotropic balancing substance;
- and
- providing a rotational element (110) comprising a chamber (120) having a fulcrum on a rotational axis (150) of said rotational element (110) comprising a circumferential balancing area (130) and being partially filled with at least a portion of said amount of said composition (240),
- wherein the hydrophobic particles have
- surfaces comprising fluorocarbon,
- cores comprising a fluorocarbon, a silicone, a metal, or carbon, or
- a specific surface area in the range from approximately 2 m2/g to approximately 20 m2/g.
