<p>The invention concerns a support arrangement for a variable-crown roll, which said roll (10) comprises a non-revolving roll axle (11), on which the roll mantle (12) is arranged revolving. 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 into 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), and the glide shoes (22) are attached to the outer ends of the pistons through the cavity spaces (23) from outside the bushing as hydraulically sealed (30), pivotally, and displaceably in the radial direction of the roll (10). The hydraulic pressure medium can be passed into the cavity spaces (23) in the pistons (21) so as to act upon the interior of the glide shoes (22) and, out of the cavity spaces (23), through capillary bores (28,28 min ) into the pockets (31) acting as hydrostatic lubrication spaces of the glide shoes (22).</p> |
