Abstract
An article that is configured to be rotatably mounted includes an embedded hollow cavity into which at least one dampening member is inserted. The dampening member or members frictionally engage the hollow cavity such that relative movement between the dampening member or members and the hollow cavity operates to attenuate vibration that is generated when the article is rotated.
Claims27
An article that is adapted to be rotatably mounted to a structure, the article comprising:
- a body structure having a rotational axis;
- a discrete hollow structure having a body portion, the body portion being disposed concentrically about the rotational axis and substantially encased in the body structure;
- and
- at least one dampening member disposed within the hollow structure and configured to frictionally engage an interior surface of the hollow structure to attenuate vibration in the article when the article is rotated.
An article that is adapted to be rotatably mounted to a structure, the article comprising:
- a first body structure formed from a first material and having a rotational axis;
- a discrete hollow structure having a body portion that is disposed concentrically about the rotational axis;
- a second body structure formed from the first material, the second body structure substantially encasing the body portion of the hollow structure and being diffusion bonded to the first body structure in a hot isostatic pressing operation;
- and
- at least one dampening member disposed within the hollow structure and configured to frictionally engage an inner surface of the hollow structure to attenuate vibration in the article that is generated when the article is rotated.
The article of claim 27, wherein the hole is oriented tangent to a portion of the hollow structure.
