Abstract: Equipment for moving a roll in a paper machine has a movable cradle (13) for attachment to a roll (10). Two pairs of masses (16, 17) are supported rotatably on the cradle (13), in each of which there is an own drive shaft (18) for rotating the pairs of masses (16, 17). Drive devices (19) include a motor (21) and drive-train means (22). The drive-train means (22) include a pair of gears (23), which are arranged in connection with the drive shafts (18), for rotating the drive shafts (18) using a single motor (21). The drive-train means (22) also includes an adjustment element (33) for creating and adjusting the phase difference of the drive shafts (18). The adjustment element (33) is arranged between a gear (25) and the corresponding drive shaft (18), to change their position and thus to create and adjust a phase difference between the drive shafts (18).

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).
