A printing unit of a printing press, comprising:
- at least one printing couple comprising a form cylinder, a transfer cylinder and an inking unit;
- at least one drive motor having a shaft and a rotor and being associated with at least one printing couple, said drive motor driving the form cylinder or the transfer cylinder of a respective printing couple;
- a flywheel mass associated with the at least one drive motor which drives the form cylinder or the transfer cylinder of the respective printing couple, said flywheel mass being connected to the rotor of the respective drive motor in a torsionally rigid manner;
- a disk;
- and
- a bearing plate connected to the shaft of the at least one drive motor;
- wherein the flywheel mass comprises a flywheel which is connected to the disk so as to be fixed with respect to rotation relative to said disk, and wherein the disk is tightly connected to the bearing plate of the shaft of the rotor of the at least one drive motor so as to be fixed with respect to rotation relative to said bearing plate.
