Definitions

  • the invention relates to a printing press cylinder according to the preamble of patent claim 1.
  • vibration-insensitive cylinders for printing machines which are constructed in several pieces and in which materials of different physical properties are used to dampen vibrations.
  • the disadvantage of this cylinder is that a multi-piece structure requires a high manufacturing and assembly costs. In addition, the manufacturing tolerances add up in a multi-part construction. By using materials with different physical Properties can occur when the temperature changes that the cylinder warp in shape. Another disadvantage is that the vibration-damping materials provided between the contact surfaces of the individual components can affect the dimensional stability of the cylinder.
  • EP 01 03 101 a device for reducing the bending vibrations excited by the channel rollover in a printing unit cylinder is known, which is filled with damping mass, inside elastic axes are arranged with an additional mass and that this additional mass is attached eccentrically and is in contact with the jacket .
  • a disadvantage of this device is that the additional mass is not arranged centrally to the central axis of the cylinder, so that a counterweight or balancing is required. Furthermore, the additional mass touches the cylinder jacket at one point, which is disadvantageous in that, when vibrations occur, the cylinder jacket and the additional mass are always subjected to the same mechanical stress, which leads to flattening or fatigue of the materials and loss of the damping effect can lead.
  • a multi-part structure also requires a lot of manufacturing and assembly work.
  • the invention has for its object to provide a printing press cylinder with vibration damping, which is inexpensive to manufacture with high precision, has good damping properties and counteracts bending of the cylinder due to its own weight.
  • the core located in the cylinder space forms a countermass to the cylinder jacket and the vibration-damping material converts the vibrations or detunes the resonance vibrations so that these vibrations become harmless.
  • the one-piece cast design of the printing press cylinder enables low manufacturing tolerances at low manufacturing costs.
  • the arrangement of balls or preassembled ball containers in the interior of the printing press cylinder not only forms a countermass to the cylinder jacket, but also creates a vibration-damping material. When using spherical containers, they can be attached directly in the vicinity of the point at which the vibrations are dissipated.
  • Fig. 1 shows a longitudinal section through a printing press cylinder 1 according to the invention, but without a channel and without a gripper device.
  • the device usually arranged in one or more channels 32, such as plate or blanket tensioning or gripping devices, is also generally not shown in the following embodiment variants.
  • the cylinder channels are in FIG. 2 shown.
  • the printing press cylinder 1 consists of a one-piece rotationally symmetrical cast body, which the cylinder jacket 2 and two end faces 3; 4 includes.
  • the cylinder jacket 2 is with the end faces 3; 4 and the end faces 3; 4 are with the axles extending in the axial direction 12; 13 firmly connected.
  • balls 37 are filled in the space from the cylinder jacket 2 and the end faces 3; 4 of the printing press cylinder 1 is formed.
  • the balls 37 preferably have a diameter of 2.5 to 3 mm and should be made of steel.
  • the balls 37 can be introduced through the filling openings 26.
  • the balls 37 serve both as a core and as a vibration-damping material.
  • the balls 37 can be compacted by shaking.
  • a pretensioning device can be arranged in the interior of the printing press cylinder 1, which further compresses the balls 37 if necessary.
  • the cylinder can also be made in several parts.
  • the cylinder jacket 2 is excited to vibrate by the channel blow. These vibrations are transmitted to the balls 37 abutting the inside of the cylinder jacket 2. The vibrations decrease more and more due to the lossy impact and movement processes of the adjacent balls 37. The damping effect can be increased if additional still viscous damping components such as oils or greases are used.
  • FIG. 2 an embodiment variant according to FIG. 1 is shown with the cross section through a printing press cylinder.
  • the cylinder jacket 2 is shown with cylinder channels 32.
  • the printing press cylinder 1 is designed according to FIG. 7, with the special feature that not the entire interior space, which is caused by the cylinder jacket 2 and the end faces 3; 4 is limited, filled with balls 37, but that two containers 38 filled with balls are attached in the axial direction 6 in the vicinity of the cylinder channels 32 on the inside of the cylinder jacket 2.
  • the cylinder channel is the area in which the vibrations are generated.
  • One or more ball containers can be installed. It is also advantageous to attach several ball containers so that additional balancing can be omitted. It is advisable to use steel balls with a diameter of 2.5 to 3 mm.
  • the printing press cylinder can be constructed in one part or in several parts. It must have an opening at the front for inserting and mounting the ball container.
  • the filled ball containers are attached through the openings in the front of the printing press cylinder so that they lie firmly against the inner surface of the cylinder.
  • the ball containers can be screwed or clamped from sheet metal and to the cylinder jacket.
