ABSTRACT:
In a method of supporting the bearing of a bearing support structure during balancing of a rotor, the bearing and the rotor journal in the bearing are permitted to rotate about the vertical, and transverse axes of the rotor journal. A spring arrangement is positioned between the bearing and vibration transducers for transferring unbalance information from the rotor being investigated to the vibration transducers. The spring arrangement allows the bearing and rotor journal to move without hindrance about the vertical, and transverse axes, such movement being caused from misalignment of the rotor journals with the axis of rotation of the rotor. Coulomb's friction is thereby eliminated for the purpose of avoiding excessively high constraining forces, spring realignment forces and frication forces.
