Adjusting spindle for adjusting applicator rollers on printing machines

摘要

The invention relates to an adjusting spindle for adjusting the applicator rollers of inking and damping units. The invention is based on the object of providing a manually operable adjusting spindle having a large adjustment range for printing machines, in particular for the adjustment of applicator rollers on inking and damping units, in which the prestressing force of the threaded spindle in the bearing block remains constant over the entire adjustment range. According to the invention, this object is achieved in that the display sleeve is connected via a thread to the threaded spindle, and a compression spring is arranged axially between the bearing block and the display sleeve. The compression spring is arranged in the display sleeve between the end of the guide tube and an inner collar of the display sleeve. The display sleeve is connected to the guide tube via a guide pin which engages with a guide slot. <IMAGE>
