| Abstract: | The precision forging process of spiral bevel driven gears in automotive final drive was simulated, using three demensional rigid plastic FEM, forging parts with a full gear tooth and metal flow procedure were obtained. The classification of forming stage for spiral bevel driven gear and filling pattern of gear tooth were acquired. Experiment results with lead workpiece validate the FE simulation by means of gear profile and forming load value. Deformation load of cold precision forging for a steel spiral bevel driven gear was predicted on the basis of similarity theory and the reasons that heavy- section spiral bevel driven gear is difficult to form under room temperature were explained and the realistic process of plastic forming for spiral bevel driven gear was proposed. |
