Problems solved by technology

The crank drive of this transverse oscillating mechanism is a planar crank drive, therefore, occupies relatively more structural space in the friction roller, which hinders the reduction of the diameter of the friction roller, and for some use cases, it is necessary to try to reduce the diameter of the friction roller. Small friction roller diameter

Embodiment Construction

[0025] exist Figures 1 to 8 A printing press 1 for offset lithography is shown in detail in the figure. The printing machine 1 comprises a friction roller 2 and a further roller 3 which is rotationally driven by friction between the rollers, so that no gear pair connecting the friction roller 2 to the further roller 3 is required. exist figure 1 The other roller 3 is marked with a dotted line in . The rubbing roller 2 comprises a multi-section roller shaft 4 and a hollow roller body 5, which is rotatable on the roller shaft 4 around the roller shaft and movable along the roller shaft. The roller shaft 4 does not rotate and is locked in a roller lock 6 designed as a quick lock. To the extent that the friction roller 2 needs to be temporarily removed from the printing press 1 for maintenance purposes, it is advantageous that the roller lock 6 can be released and locked quickly.

Abstract

The mechanism has a crank mechanism (7) arranged in an interior of a distributor roll. The crank mechanism has three-dimensional mechanism kinematics which transform rotation of a roll barrel into its axial to-and-fro movement. The crank mechanism has a crank connected to a crankshaft in a rotationally articulated manner via a joint, and is connected to a lever arm of a swing arm via another joint (12). - An INDEPENDENT CLAIM is also included for a printing machine and distributor roll combination.

Description

technical field [0001] The invention relates to a lateral pivot mechanism for a friction roller of a printing press, which includes a crank drive. Background technique [0002] Such a lateral pivot mechanism is described in DE 185 198 . The crank drive of this transverse oscillating mechanism is a planar crank drive, therefore, occupies relatively more structural space in the friction roller, which hinders the reduction of the diameter of the friction roller, and for some use cases, it is necessary to try to reduce the diameter of the friction roller. Small friction roller diameter. SUMMARY OF THE INVENTION [0003] It is therefore the object of the present invention to provide a oscillating mechanism which facilitates a reduction in the diameter of the friction roller. [0004] According to the invention, a lateral pivot mechanism for a friction roller of a printing press is proposed, which comprises a crank drive, wherein the crank drive is a space crank drive. [000...
