Rigid-flex Hybrid Model Foundation and Statics Simulation Analysis for the NGW31 Planetary Gear Reducer Based on Romax Designer

With the NGW31 planetary gear reducer as the research object, combined with the related pa rameters of the planetary gear reducer, the traditional rigid model of the transmission system was established based on the conceptual model. And the traditional rigid model is taken as the basis, rigid-flex hybrid model of transmission system was established for a NGW31 planetary gear reducer based on the Roamx Designer. At the same time, the statics analysis was taken for the gear of planetary gear reducer under the two models of traditional rigid model and rigid-flex hybrid model. The results of analysis show that maximum contact stress of the gear under the rigid-flex hybrid model is significantly greater than the traditional rigid model, it is more close to the real conditions, which indicated that the rigid-flex hybrid model is more reasonable and reliable than the traditional rigid model.
