Abstract:
PROBLEM TO BE SOLVED: To provide a tool to forcibly axially mount and demount a bearing assembly part in a mounting position on the neck part of the roll of a rolling machine.
SOLUTION: A tool 64 is provided with a piston 74 surrounded by a cylinder 66. The piston 74 is removably fixed at the neck part 12 of a roll and the internal part of the cylinder 66 is further divided into first and second chambers. A fluid flow passage selectively pressurizes the first and second cylinders. Regarding the piston to fix the cylinder in a manner described above, the cylinder is situated such that selective displacement is executed in first and second directions, opposite to each other. Through movement in the first direction of the cylinder, a bearing assembly part 10 is forcibly displaced to its mounting position, and further through movement in the opposite second direction of the cylinder, a bearing assembly part 10 is forcibly moved from its mounting position.
