Abstract
A roller arrangement with a deflection compensation roller and a counter roller. The deflection compensation roller has a shell, through which a hydrostatic support device is supported on a carrier. The shell-ends are each supported on a ring bearing which is guided in an action plane and is radially adjustable and can be loaded by a force in the slide direction. The shell-ends can each be loaded by a torque which has an axis perpendicular to the action plane. In this way, the deflection of the shell can be matched to be proportionate to the deflection of the counter roller.
Claims10
Roller arrangement comprising:
- a counter roller;
- a deflection compensation roller;
- a pressure gap defined by said deflection compensation roller and said counter roller, said deflection compensation roller comprising a radially movable shell which is supported by and connected to a carrier by a hydrostatic support device, said shell having first and second ends which are each supported by a ring bearing, said first and second ends having first and second support flanges, said ring bearings being radially adjustable in a radial adjustment direction and loaded by a force in said radial adjustment direction by an energizer, said energizer comprising a cylinder and a piston, said first and second ends of said shell are loaded by a torque produced by a torque-producing element which exerts pressure in a direction perpendicular to said radial adjustment direction, onto at least one of said first and second support flanges;
- and
- a control device for at least one of independently and proportionally controlling and setting a resulting force of the energizer and a resulting torque of said torque-producing element.
