Abstract
An absorber for damping vibrations in a rotating component includes a primary part connectable to the rotating component so as to be fixed against rotation relative thereto; an absorber mass; the primary part and the absorber mass being couplable to one another via a damping and spring coupling so that the absorber mass is rotatable to a limited extent relative to the primary part; at least two antifriction bearings for mounting the absorber mass on the rotating component; the two antifriction bearings being nested within one another, so that one of the antifriction bearings is seated on a larger radius than the other; and an intermediate ring disposed in a radial direction between the two antifriction bearings.

An absorber for damping vibrations in a rotating component, comprising a primary part connectable to the rotating component so as to be fixed against rotation relative thereto;
- an absorber mass;
- said primary part and said absorber mass being couplable to one another via a damping and spring coupling so that said absorber mass is rotatable to a limited extent relative to said primary part;
- at least two antifriction bearings for mounting said absorber mass on the rotating component;
- said two antifriction bearings being nested within one another, so that one of said antifriction bearings is seated on a larger radius than the other;
- and an intermediate ring disposed in a radial direction between said two antifriction bearings.
The absorber according to 3, wherein said inner and said outer bearings constitute a first bearing pair, and including, axially adjacent said first bearing pair, a second bearing pair having bearings likewise nested within one another;
- and an intermediate ring also disposed between said bearings of said second bearing pair.
