<p>The invention relates to a shaft extension (30) for the shaft (3) of a fiber web processing element, where the shaft extension comprises a first end (31) for fastening to the shaft of the fiber web processing element and an opposite second end (32) for a rotating device of the fiber web processing element, and fastening accessories for fastening the shaft extension rigidly by the first end to the shaft in a manner which transmits the rotating torque. At the first end (31), the shaft extension (30) comprises a fastening element (34), which can be fitted with the shaft (3) of the fiber web processing element, within each other, so that the fastening element and the shaft of the fiber web processing element form a circular installation gap (33) between them, and the shaft extension comprises (30) the first adjustment pieces (40), which can be fitted in the installation gap, and the adjustment pieces can be adjusted jointly or individually in order to change the radial size of the installation gap locally at each adjustment piece so that the shaft extension can be adjusted to become concentric with the axis of rotation of the shaft of the fiber web processing element and so that the installation gap can be filled with a fixing agent (50) for joining the shaft extension and the shaft of the fiber web processing element together. The invention also relates to a fiber web processing element, to a method for the fastening of the shaft extension (30) to the shaft (3) of the fiber web processing element, and to a method for the fastening of a roll drive (10) to the end (2') of the fiber web processing element (1), such as a roll, by means of the shaft extension (30).</p> |
