Aerostatic bearing for large rotor

, 2023
In cardboard and paper manufacturing, the paper web is handled with large scale rolls. From the machine design point of view, those rolls are large rotors with high stiffness, accuracy and balance requirements. In paper machines, the rotors not only guide the web but also are used to perform different treatments for the manufactured product.

FEEDING SYSTEM OF AEROSTATIC BEARINGS WITH POROUS MEDIA

Proceedings of the JFPS International Symposium on Fluid Power, 2005
In porous resistances, Darcy’s law provides a good approximation of mass flow rate when the differences between upstream and downstream pressures are sufficiently small. In this range, the mass flow rates are proportional to the porous resistance’s permeability.
