An adjusting device ( 11 ) is for regulating the eccentric moment of an eccentric shaft ( 2 ) of a roller drum ( 1 ) through the influence of an axially directed force transmitted by a force transmission mechanism ( 12 ) to a turning device ( 5 ), in order to cause a rotation of the eccentric shaft ( 2 ). The force transmission mechanism ( 12 ) is connected to the adjusting device ( 11 ). The adjusting device ( 11 ) incorporates a driving device ( 20 ), a transmission ( 19 ), a tube sleeve ( 17 ) and a guide screw ( 14 ) which is rotatably arranged in a threaded bore ( 16 ) in a journalling shaft ( 15 ) for the roller drum ( 1 ). The driving device ( 20 ) is connected to the tube sleeve ( 17 ) via a transmission ( 19 ) for transmitting a rotary movement to the tube sleeve ( 17 ). The guide screw ( 14 ) is arranged outside the tube sleeve ( 17 ) with a spline joint ( 18 ) whereby the guide screw ( 14 ) is displaced axially when the tube sleeve ( 17 ) is rotated and consequently transmits an axial movement to the force transmission mechanism ( 12 ) which is connected to the guide screw ( 14 ) via a bearing assembly.
