Note:

Several companies allready have measured the noise and vibrations of this KRUPP gearbox. We offered not only to measure the installation, but promised to solve the problem. After checking and correcting the alignment, we examined the relation between the axial movement of the input shaft and the noise production of the dryer drum. We are now proposing a modification of the installation.
