摘要： The invention concerns an adjustable-crown roll having a stationary roll axle which is supported on the machine frame by means of articulated bearings, and a roll mantle which is arranged to revolve on the axle. Hydrostatic loading members or an equivalent pressure fluid chamber or series of chambers are arranged in the space between the axle and the roll mantle. By means of the loading members or equivalent, the profile of a nip formed with a counter-roll of the roll is regulated. A support bushing arranged concentrically with the roll mantle is attached to one end of the roll mantle and revolves along with the roll mantle. A bearing is installed on the support bushing. The bearing receives axial forces from the roll mantle and transfers the same to the machine frame through the non-revolving bearing bock or housing of the bearing. The bearing is arranged, in the axial direction, outside the roll, whereby the roll is suitable for use as a hot roll.

摘要： A support arrangement is provided for a variable-crown having a non-revolving roll axle (11) on which the roll mantle (12) revolves. The roll mantle (12) is supported on the roll axle (11) by means of hydraulic loading members (20) which comprise pistons (21) fitted into cylinder bores (15) formed in the roll axle (11), as well as glide shoes (22) supported on the inner face (14) of the roll mantle. The pistons (21) are composed of bushings provided with inside cavity spaces (23). The glide shoes (22), which are attached to the outer ends of the pistons through the cavity spaces (23) from outside the bushings, are hydraulically sealed (30), and are pivotal and displaceable in the radial direction of the roll (10). A hydraulic pressure medium is passed into the cavity spaces (23) in the pistons (21) so as to act upon the interior of the glide shoes (22). The hydraulic medium passes, via the cavity spaces (23), through capillary bores (28,28') into pockets (31), the latter acting as hydrostatic lubrication spaces of the glide shoes (22).

摘要： A method and apparatus for obtaining substantially uniform profiles of the roll mantles of an adjustable-crown roll and a counter-roll at a nip formed therebetween wherein the bearing distance of the counter-roll is substantially larger than the bearing distance of the adjustable-crown roll and wherein the nip is loaded by load forces applied to one or both rolls, preferably at regions of the bearings. A compensation moment is produced by devices situated within the mantle of the adjustable-crown roll between the bearings thereof loading both end regions of the roll mantle, the magnitude of the moment adjustable by adjusting the moment-producing compensation force such that the profiles of the deflected roll mantles of the adjustable-crown roll and the counter-roll at the nip are substantially uniform.
