Side frame of a printing machine

The invention relates to a side frame of a printing press according to the preamble of claim 1.

By DE 44 30 693 A1 are printing units, in particular a plurality

Double printing units superimposed printing units, known, whose cylinders are mounted on both sides in side frames.

EP 1 644 191 B1 discloses an I printing unit of an illustration printing machine, wherein two printing units printing the two web pages are arranged one above the other. The cylinders are mounted in a side frame, wherein between the cylindrical bearing on the drive side bearing side frame and on this frontally disposable cover a lubricant space can be formed. A drive motor driving the cylinders is arranged on a carrier plate, which is connected via studs to the side frame wall.

DE 10 2009 001 481 A1 relates to a printing unit of a commercial printing press with two superimposed, together forming a double pressure point

Printing units. DE 10 2009 001 481 A1 seeks to provide a machine with reduced effort for installation and commissioning. For this purpose, to the

Pressure units already provided for alignment before delivery and the aggregate-internal media supply prepared. On the Au ßenseite a drives opposite side frame an electrical cabinet is provided in which u. a. Drive controllers are provided for the drive motors.

DE 20 2005 006 919 U1 discloses a drive unit of a component of a Printing machine, a servo drive controller should not be located in a cabinet, but directly on the engine. The drive unit is provided in an example for driving printing unit cylinders of a printing unit. Here are the

Printing cylinder mounted by four Duckwerken in a side frame and driven in pairs by such drive units. In a schematic representation, the drive units are arranged on a kind of rear wall of the side frame, which runs between two opposite lateral collars of the side frame.

From DE 101 63 963 A1 discloses a drive of a printing unit is disclosed, wherein in one embodiment, the printing cylinder of four printing units of a printing unit are each driven in pairs by a drive motor.
