Abstract

A radially adjustable gearwheel for driving a cylinder of an offset press. The gear rim has a peripheral annular groove opening axially outward and dimensioned to receive a tensioning ring including inner and outer body parts engaging each other along an inclined tapered surface. A plurality of tensioning devices are mounted on the gear rim and act axially on the tensioning ring causing the inclined surfaces of the inner and outer body parts to slide against each other resulting in radial displacement of the outer body part which produces radial deformation of the gear rim.
