Vibration damper, has outer damping mass circularly enclosing inner damping mass in plane running parallel to base, where damping masses are flexibly coupled to base under formation of different natural damper frequencies

摘要

The damper (1) has an inner damping mass (5) and an outer damping mass (6) i.e. rotational body, that are flexibly coupled to a base (2) independent of each other under formation of different natural damper frequencies. The outer damping mass circularly encloses the inner damping mass in a plane running parallel to the base. The outer damping mass in the plane forms a closed ring (14) around the internal damping mass. The inner damping mass circularly encloses a casing held by an elastomer material (10). The casing forms elastomer springs (8, 9) for coupling the damping masses to the base.
