doi:10.3901/JME.2018.11.205

Abstract

Abstract: Gear honing process and gear grinding process are the main techniques of gear finishing. It is one of the significant research fields to investigate the process principle and know clearly about the formation mechanism of tooth surface texture of gear honing and grinding process. A method of sampling points tooth surface modelling is presented based on spatial conjugate meshing theory. Based on this method and theories, the tooth surfaces contact areas of honing wheel and worm grinding wheel are built respectively. The honing path and grinding path models are generated according to the velocity vector of the sampling points on tooth surface. The roughing processed and heat treated work-piece gears are grounded as the gear blanks of finishing process, gear finishing are carried out on CNC gear honing machine and gear grinding machine, the 3D topography experiments of gear teeth are conducted to verified the predicted model of the tooth surface path of each gear finishing process. The result shows that the predicted model display some similar texture features with the experiment result. Combined with the comparative analysis of the index data of 3D topography, the influence law of gear grinding and gear honing on geometric precision of tooth surface is finished. The results of this research have important theoretical and instructional significance for the improving of gear honing and grinding process.
