Abstract

PURPOSE:To improve the toughness of the sleeve inside extremely, by applying plastic working to only the inside of sleeve for shrink fit by pressurizing. CONSTITUTION:A sleeve 2 is preliminarily heated to a tmperature capable of applying plastic working. The sleeve 2 is supported by three upper and lower drive rollers 3, 3', 3'', and the rollers are rotated to rotate the sleeve 2 in one direction. Next, a form rolling roll 4 which is in contact with the inside of the sleeve 2 is rotated through a support shaft 5. The circumferential end of the form rolling roll 4 is smaller in diameter, so that the pressurizing force per unit area is large. Thus, by pressurizing the inside of the sleeve 2 and moving the form rolling roll 4 in the widthwise direction of the sleeve 2, the entire inside surface of the sleeve is given plastic working. As a result, the coarsening texture of the inside of the sleeve 2 becomes the texture extended in the tangential direction to be dense, so that the toughness may be extremely improved.
