Rotary roller printing press drive - has sprocket wheels, pinion, and serrated belt pulley connection with reversible electric motor

摘要

All printing assemblies and folding equipment are driven by a common shaft, via intermediate gear and an upright shaft, in a rotary roller printing press. The lengthways shaft section(8) for the printing assembly has two sprocket wheels(7,17) mounted on it. A sliding coupling sleeve(25) is mounted between these, on a multi-wedge part(21) of the section, detachably form-locked to the part. It is selectively coupled to the wheels, which are in contact with a sprocket wheel pinion(12) form-locked to the upright shaft (13). A sprocket wheel is form-locked to a toothed belt pulley(5) via a belt(3), the pulley being force-locked to a reversible electric motor(2). The direction of drive for the printing assembly can be reversed, and it can be driven independently of the lengthways shaft, without auxiliary motors.
