Abstract
The invention concerns a connecting structure (10) between a driving transmission (11) and a roll (100) driven through it. The driving transmission (11) includes an input shaft (12) in the drive, whereby through the input shaft (12) the drive is transferred to toothed gears and further to the roll jacket (100a) of the driven roll (100) to rotate it. The roll (100) includes a central static shaft (100b) and a bearing (G) to support it. In order to allow axial and radial motions of the roll's (100) roll jacket when the driving transmission (11) is in the fixed position, a seal (25) including a sliding ring (30) is fitted in between the driving transmission (11) and the roll (100).

A connecting structure comprising:
- a driving transmission (11) and a roll (100) connected through it, which driving transmission (11) includes an input shaft (12) in the drive, whereby the drive is transmitted through the input shaft (12) to toothed gears and further to the roll jacket (100a) of the driven roll (100) to rotate this, and which roll (100) includes a central static shaft (100b) and a bearing (G) to support it, wherein in order to allow axial and radial motions of the roll's (100) roll jacket when the driving transmission (11) is located in the fixed position, a seal (25) including a sliding ring (30) is fitted between the driving transmission (11) and the roll (100).
