Abstract
An arrangement on a press having an eccentric shaft for adjusting the strokes of a working slide and of a counter-oscillating weight by adjustable eccentric/eccentric bush pairings. The eccentric bushes of these pairings can be detached and fixed on the eccentrics in the rotating direction since the connection is in each case an interference fit with a cylindrical locating surface that can be released by the feeding of pressure oil. This permits a narrow construction of the press with a relatively short eccentric shaft. The eccentrics are arranged directly next to one another on an eccentric shaft, and the eccentric bushes are rotationally connected with one another via radial disks with radial slots and pins engaging in them. The adjusting of the strokes takes place by rotating the eccentric shaft when the interference fits are released and the eccentric bushes are locked.
