The Parameters Influencing the GWN
Authors: V. Niola, G. Quaremba, V. Avagliano
Abstract: This study describes, from the experimental point of view, the parameters influencing the phenomenon called “gear whine noise”, which involves the gear-box. A particular attention is devoted to the main causes of such an acoustic emission (e.g., micro-geometry of the tooth and tooth surface texture) and to the most appropriate modifications to be carried out already during the design stage, in order to reduce it. In particular, a comparison was carried out in the fourth gear, from vibro-acoustic point of view, on gear-boxes, showing micro-geometric differences, made by two different makers.
