Abstract
A vibration absorber for rotating body of this invention comprises a disc capable of moving only in the horizontal direction accompanying the vibration of a pivot and an annular plate placed on the disc and capable of moving only in the vertical direction, the vibration energy of rotating body being absorbed by the shearing force of an oil film formed by the relative motion between the horizontally moving disc and the vertically moving annular plate.
Claims8
A vibration absorber for a rotating body comprising a tank including at least side and bottom portions and containing a viscous liquid substantially filling said tank, a spherical surface formed at one end of a vertically extending pivot, a first member located adjacent the bottom of said tank and having a partially spherical surface to fit on said spherical surface of the pivot and capable of moving in the horizontal direction, a hollow second member placed on top of said first member and capable of moving in the vertical direction independently of the horizontal movement of said first member, and a centripetal means for locating the center of said first member on the central axis of said pivot upon moving said first member in the horizontal direction, all of said members and means being disposed within said tank.
