Abstract
A vibration damping device is configured to reduce vibration that causes lateral flexing of an elongated member that extends along a centerline. The device includes a split sleeve co-extending with and disposed about the elongated member, and a spring that extends about the sleeve and exerts a force that biases the sleeve radially inward.
Claims13
A vibration damping device for reducing lateral displacement of an elongated member extending along a centerline, the vibration damping device comprising:
- a split sleeve co-extending with and disposable about the elongated member;
- and
- a first spring extending about the sleeve and configured to exert a force that biases the sleeve radially inward against the elongated member to react against lateral motion of the elongated member, wherein the first spring is a coiled spring constructed and arranged to helically wrap about the sleeve.
A gear train comprising:
- a first gear orientated to rotate about an axis;
- a second gear orientated to rotate about the axis;
- and
- a quill shaft assembly extending axially between the first and second gears, and including a quill shaft engaged to the first and second gears and including a plurality of segments, a connecting rod concentrically disposed inside the quill shaft and configured to hold the plurality of segments axially together, a split sleeve disposed about the connecting rod, and a first spring extending about the sleeve for exerting a force that biases the sleeve radially inward against the quill shaft for damping vibration of the quill shaft.
