Abstract
In a deflection controlled roll (1) having a non-rotatable carrier (4), a rotatable roll jacket (7) is supported against the carrier (4) by a number of hydrostatic supporting elements (8) with adjustable pressing force. The supporting elements (8) run in corotating bearing races (9) mounted loosely in the roll jacket (7) and corotating with the roll jacket (7) but independently therefrom. These bearing races (9) are provided on both sides with flanks (15) for axial positioning, which cooperate with side bearing pockets on the supporting element (8) and form an axial guideway for the bearing race (9). Automatic positioning with maintenance of a defined bearing gap is achieved by a toroidal cross-sectional or a tapered ring-shaped construction of the running surfaces of the supporting element (8) and the bearing race (9).
Claims10
Deflection controlled roll (1) having a roll jacket (7) which is rotatable about a non-rotatable carrier (4), said roll jacket (7) being supported against said carrier (4) by at least one hydraulic supporting element (8), which is mounted by means of at least one hydrostatic bearing pocket (11, 18, 20) on a bearing race (9) corotating loosely in said roll jacket (7) and exerting a pressing force on said roll jacket (7) via said bearing race (9), characterized in that said supporting element (8) has at least one hydraulic bearing surface (19, 21, 26) which forms an angle with the axial direction (A) of said roll jacket (7) and in that said bearing race (9) has a similarly oriented running surface (25, 29, 31) cooperating with the bearing surface which, together with the bearing surface of said supporting element (8), forms an axial guideway for said bearing race (9).
