Torsional and structure-borne sound analysis
Torsional vibrations can often correlate with the torque signal.
The following analyses are therefore carried out:
the structure-borne noise signals are recorded with an acceleration sensor on the roller housing.
The recorded measured values are analysed in the time and spectral domain, such that the acoustic behaviour of the machine is analysed.
Such torsional vibrations occur in particular in roller gearboxes in which rollers and cylinders (rolling elements) are combined.
The transmission of torque and movement is based on the principle of frictional force transmission.
Particularly in the case of rolling elements that guide the material, a uniform rotary motion is crucial in order to
precise positioning of the material to be guided and
exact parallelism of the rollers.
This also applies to printing machines where several layers of colour are applied to the material.
