MOTOX gearbox - DS TECH

Technical data10.4 Sound-pressure level10.4 Sound-pressure levelThe A rated sound-pressure level LWA of a selection of gearboxes in the following figure hasbeen measured to DIN EN ISO 1680 with meters to DIN IEC 60651.The noise depends mainly on speed, output, and transmission ratio. Figure 10-3MOTOX geared motors sound-pressure levelThe sound-pressure levels of MOTOX geared motors fall mainly in the dark-colored part ofthe range. Gearboxes with very small transmission ratios, high output, and high input speedmay fall into the cross-hatched part.If repeat measurements on site do not produce conclusive results which can be verified bymeasuring technology, the measurement obtained on the Siemens Geared Motors GmbHtest benches will apply.External noisesNoises not generated by the gearbox but emitted from it are not taken into considerationhere.Similarly, noises emitted from the input and output machines and from the foundation are nottaken into consideration here, even if transmitted to these by the gearbox.BA 201084 Operating Instructions, 05/2011
