Embodiment Construction

[0025] In the Campbell plot ( figure 1 ), with respect to the rotational speed of the components as the ordinate, on the abscissa the natural frequencies of the different driven and driven components of a machine for producing and / or processing fibrous webs according to the prior art are plotted .

[0026] figure 1 It is shown how, in machines according to the prior art, depending on the operating drive or driven drive train, resonances can occur, ie vibrations are induced in the range of the natural frequency of the drive train, the vibrations are only slightly attenuated and thus Amplified by additional energy delivery. The frequency is shown by lines 1, 2 and 3 as a function of the double rotational speed of the unit consisting of the motor and clutch and the unit consisting of the cardan shaft and roller Vibration or cycling during operation at different rotational speeds.

[0027] Use 4 to represent the fundamental torsional natural frequency of the drive train, and a...

Abstract

The invention relates to a machine for producing or processing a fibrous material. The machine is provided with at least one power train system and is characterized in that a vibration attenuation adapter (12) is arranged on at least one position in the power train system.

Description

technical field [0001] The invention relates to a machine for manufacturing or processing fibers according to the invention. Background technique [0002] The drive trains of machines for manufacturing or processing fibers or substrates, i.e. for example paper machines, board machines, coaters and tissue paper machines, are now standardized by cardan shafts, transmissions and multiple disc clutches, In particular, a backlash-free, torsion-resistant and maintenance-free composite design of all-steel couplings for compensating axial and radial shaft misalignments and angular misalignments. These components result in a drive train with little damping of torsional and bending vibrations. [0003] The drive train behaves as a multi-mass vibrator which, depending on its structure and depending on the components making up the multi-mass vibrator, has a plurality of torsional natural frequencies. Natural frequencies can be excited, which can lead to resonance. However, the format...
