ABSTRACT:
A radially adjustable gearwheel for driving a cylinder of an offset press. The gear rim has three axially disposed tapered bores into which axially tapered bolts can be pressed to act radially on the gear rim. Additional axial bores are provided between the tapered bores to form expansion webs in the gear rim. The tapered bolts, in conjunction with the expansion webs, subject the gear rim to varying radial deformation in a gently rising parabolic curve depending on the tension applied to the tapered bolts so that the deformed gearwheel rolls with minimal impact and shock forces.
