Abstract
In this paper, a computational model is proposed to predict the noise radiation of a planetary gear reducer. In addition, a system-level vibro-acoustic model of a two-stage planetary gear reducer is also established, and the dynamic contact equations of engagement are deduced to investigate the dynamic loads at the interface of bearing-housing and ring-housing in operation, using a large mining two-stage planetary reducer as a test mechanism. Moreover, the frequency response of the planetary transmission has been derived, the radiation noises from the two-stage planetary gear train are analyzed, the simulation results agree well with the experimental results. This research can be guide structural optimization of planetary gear mining reducer.
