Abstract: | The paper provides an investigation into the influence of the periodic variation in the boundaries of the dead-zone between the teeth, caused by the Transmission Error, on the gear rattle phenomenon.The study represents an evolution of a theoretical model, which has already been developed by the authors, to analyze lightly loaded gear pairs, accounting for oil squeeze effects between the gear teeth.An experimental test rig and a methodology to estimate the transmission error parameters, starting from an experimental acquisition, are described.A number of experimental-theoretical correlations concerning the influence of transmission errors on gear dynamics are reported in order to validate the theoretical model. |
