| description | A vibration damping device for use with a downhole tool having a tool axis and a drill string component (DSC), may comprise an inertia ring rotatably mounted on the DSC and including at least one cutout defining a chamber therein such that the DSC forms an end wall of the chamber, and a leaf spring disposed in the chamber, the leaf spring having first and second spring ends, the first end being attached to the inertia ring or the DSC such that relative rotation between the inertia ring and the DSC distorts the leaf spring. The second spring end may engage the other of the inertia ring or the DSC. A fluid may be included in the chamber and the spring may divide the chamber into two portions, so that relative rotation between the inertia ring and the DSC distorts the leaf spring and varies the volumes of the portions. |
