Abstract: A heatable controlled deflection roll contains hydrostatic support elements, each of which is supported in a pressure chamber and displaceable in a predetermined support or pressing direction. Heating of the rotatable roll shell or jacket of the controlled deflection roll is accomplished by infeeding a heated hydraulic heat carrier medium to bearing pockets of the hydrostatic support elements. This infeed of the heated hydraulic heat carrier medium is effected operationally separate from the provision of the pressure chamber with hydraulic pressurized fluid medium colder than the heated hydraulic heat carrier medium. The infeed of the hydraulic heat carrier medium and the infeed of the hydraulic pressurized fluid medium are thus accomplished via separate lines without thermal stressing of associated regulating valves and pumps and without a viscosity reduction of the hydraulic pressurized fluid medium, such viscosity reduction resulting in a loss of hydraulic pressurized fluid medium.

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.
