DEVICE FOR CONVEYING OSCILLATING AXIAL MOTIONS TO A ROTATABLE ROLLER

摘要

The invention applies to a device for conveying oscillating axial motions to a roller being rotatable around a geometrical main axis of rotation (R), which device comprises a reduction gear (10) that is connectable to the roller and connected to a transmission member (17) being moveable axially to-and-fro and connected to a rotor (18) being rotatably journalled in a holder (33), around a secondary axis of rotation (S) via a hinge (19) being radially spaced from the main axis of rotation (R), said hinge being planetary moveable in a path, the angle of which relative to the main axis of rotation determines the axial length of stroke of the transmission member and thereby the axial length of stroke of the roller. According to the invention the reduction gear (10) and the transmission member (17) are housed in a housing that comprises a fixed wall shell (32) as well as a casing (33) serving as holder for the rotor (18), said casing being turnable relative to the wall shell (32) to provide readjustment of the axial length of stroke of the roller.
