Abstract：

With regard to the deformed gear and defects produced in the platetype cross wedge rolling experiments and productions on involute gear shaft, the reasons for deformed gear and defects phenomenon occurring at the initial rolling stage and middle to late forming stage of rolled piece tooth profile were analyzed, and a simulated optimization design on the deformed gear and defects phenomenon in the above stages was carried out by adopting Deform3D finite element software. Results of the simulation are that the disordered gear phenomenon has been basically eliminated and scale division of gears becomes even and shape of tooth profile is clear. Finally, a physics experiment, whose results are basically in consistent with the results of simulation, was carried out on the simulated optimization design of finite element, so as to provide more efficient references to further research and production on wedge cross rolling of gear shaft.
