Abstract
A mill roll with a deformable casing comprises a tubular casing (1), a fixed support (2) and a set of elements (3) for holding the casing in the radial directions. At least one chamber (9) fed with high-pressure fluid is formed between the fixed support (2) and each of the holding elements (3). The end of the holding elements (3) is separated from the inner surface of the casing (1) by means of a fluid film occupying a zone (12) in the form of a sector of a ring. The zone (12) is in communication, at one of its ends, with a low-pressure fluid feed duct (14) and, at its other end, with a fluid recovery duct (15). This results in the formation of a hydrodynamic bearing during the rotation of the casing (1), which is fed completely independently of the high-pressure supply to the chamber (9).
