Abstract

Based on the analysis of expanding cup wheel topography, grinding wheel model, whose grain diameter and space position on the wheel surface are distributed randomly, is established and used to simulate grinding tooth surface topography. Based on the analysis of the formation mechanism of grinding tooth surface topography, the relative movement relationships between grinding wheel and tooth surface, and the interference and superimposition principle of grain tracks, the modeling and simulation of grinding tooth surface morphology of spiral bevel gear are made. The simulation morphology of grinding tooth surface of spiral bevel gear is obtained by Matlab software. By the comparative study on experiment, The results show that the simulation morphology and experimental observing one is basically identical. These indicate that the topography simulation model of grinding tooth surface of spiral bevel gear established in this paper is more accurate and reasonable.
