Radial vibration dampers for rotating shafts |
摘要 |
Radial vibration dampers (RVD's) press-fittable to a shaft and shaft systems incorporating RVD's are disclosed herein. The RVD's include a first inertia member and a second inertia member fixedly connected to one another to define an annular channel having a radially facing, open side and a spring damper material seated in the annular chamber and axially compressed between the two inertia members. The spring damper material has a compressible portion protruding from the radially facing, open side so that, when the compressible portion is compressed against a shaft, the spring damper material defines a gap between the shaft and the inertia members. The RVD may be press-fittable inside a hollow shaft or to the outside of a hollow or solid shaft. The RVD's disclosed herein have first vibration mode shapes that are radial in nature and decoupled from latter vibration modes. |

1. A radial vibration damper comprising:
a first inertia member and a second inertia member fixedly connected to one another to define an annular channel having a radially facing, open side; a spring damper material seated in the annular channel in axial compression between the first inertia member and the second inertia member; wherein the spring damper material has a compressible portion thereof protruding from the annular channel through the radially facing, open side and the compressible portion is exposed for contact in radial compression against a shaft; wherein the compressible portion exposed for contact in radial compression against the shaft defines a gap separating the shaft a distance apart from the first and second inertia members. |
