Abstract

In order to quantitatively reflect the influence degree of various random factors on the reliability of the reducer system, the gear reducer is taken as the object of research in this paper. Firstly, the gear contact fatigue is taken as the main failure mode, and then the tooth contact stress response is calculated by ANSYS/LS-DYNA. As a result, the response function is established based on the response surface method (RSM); secondly, Monte Carlo simulation with 2000 samples were carried out through the probabilistic design system (PDS) module of ANSYS, so that the influence of bearing clearance, gear's pitch error and tooth width machining error on tooth surface contact failure was obtained. This study provides an important theoretical basis for the optimal design of the reducer.
