Abstract
PURPOSE:To let the movement of the sleeves be smoothly effected by forming pressure acting grooves in the sleeve fitting surface of the outside circumference of a roll body or the fitting surface of the inside circumference of the sleeve and communicating the fluid paths formed in the roll body to these. CONSTITUTION:A rolling roll with sleeve 1 is constituted by a roll body 10 and a sleeve 11 which has been shrinkage-fitted at a desired interference fit to the outer side of said body. Plural pressure-acting grooves 12 which are shorter than the outside circumference of the sleeve 11 and are extending in the axial direction or further the annular grooves communicating with these grooves 12 are formed on the outside circumference of the roll body 10 and are communicated to the fluid paths 14, 15 running in the roll body 10. The liquid pressure supplied through the fluid paths 14, 15 acts upon the inside circumferential surface of the sleeve 11 and expands the sleeve 11 in the radial direction. In association to the liquid pressure to the grooves 12, a cylinder 5 operates to slide the sleeve 11 axially to the desired position.
