Abstract

PURPOSE:To restrain a local axial slip of a sleeve under an excessively heavy load, and to prevent a residual bend of a roll shaft, by uniffying a main shaft and a sleeve into one body through screw joints arranged in proximity to both ends of the main shaft and the sleeve, and by making these jointing screws on the left and right sides reverse to each other. CONSTITUTION:At the neighborhood of the left and right ends of the inner surface of a sleeve 3, double or sinble threaded internal screws 4, 4 are provided in mutually reversed spiraling directions; hereupon, etch screw has a thread in a height a little shorter than a radial expansion clearance of the sleeve 3. Meanwhile, the left and right ends of the outer surface of the main shaft 1 are provided with external screws 2, 2 fittable to the said internal screws 4, 4. Then, the sleeve 3 is heated to about 300 deg.C usually, and is shrink-fitted to the main shaft 1 preparing a shrink fit allowance ratio of about 1/1000. Thus constituted sleeve type composite roll can prevent a residual bend in the roll axis that is a defective point of a conventional shirnk- fitted sleeve type composite roll, so that the dimensional accuracy and stability of the rolled product are improved.
