Embodiment Construction

[0047] The printing machine of the present invention and the working steps of the method of the present invention will be described in detail with reference to FIG. 1 and subsequent embodiments. Without loss of generality, it is shown that for a certain circular frequency ω s or compensation for mechanical vibration or disturbance of a machine shaft of machine frequency order r, where r is a real number. Because for a certain circular frequency ω s The compensation of the mechanical vibration or disturbance is carried out in a manner independent of other circular frequencies or orders, the so-called superposition principle, so this method can especially be used for any number of different circular frequencies ω si or order r i Compensation is performed, where i is a natural number, and the method can be used both simultaneously and sequentially. This makes it possible for the machine shaft to turn at a constant speed even when non-uniform moments act on it.

Abstract

The method involves superimposing at least one of the discrete frequency components of the mechanical vibration (2) with an essentially harmonic torque (14) of equal frequency with a defined amplitude and phase by an actuator (11) and independently of the other frequency components so that the vibration amplitude at this frequency is reduced. Independent claims are also included for the following: a group of printing mechanisms and a printing machine.

Description

[0001] This case is a divisional application of the patent application with the filing date of October 26, 2001, the application number of 01134307.9, and the invention title of "Method for Compensating Mechanical Vibration in Machines". technical field [0002] The invention relates to a method for compensating mechanical vibrations, in particular rotational vibrations, on a machine shaft, especially on a printing unit or printing press shaft, by means of at least one actuator acting directly or indirectly on the machine shaft, said vibrations having A spectrum that can be approximated by a number of discrete frequency components. [0003] Furthermore, the invention relates to a printing unit having at least one machine shaft driven by means of an actuator and a measuring device for measuring mechanical vibrations of the machine shaft. Background technique [0004] Mechanical vibration not only refers to the periodic change of one or more coordinates of the machine shaft, s...
