Abstract：

For the existed problems of low rolling efficiency and poor consistency of workpieces, etc., during the rolling process of ring gear blank with bar or strip, a five-roller rolling process which can form butt welding ring by rolling only once was put forward. The position of craft roller was calculated, and the corresponding relationship of side-roll displacement and radius of curvature were deduced. To avoid the blindness of the experiment，intuitively reflect the general rule of gear blanks forming, shorten the development cycle of products and lower the output cost，the rolling process was dynamically simulated by the finite element software ANSYS/LS-DYNA. Then the deformation and the stress field distribution of the blank in the rolling process were analyzed. Finally, the simulative results were compared with the calculated results, and the comparative differences were analyzed，which verified the feasibility of five-roller rolling process.
