| Abstract: | According to part drawing of spiral bevel driven gear of automotive final drive, the preformed blank and experimental die have been designed and manufactured. Test results of lead work-pieces verify the feasibility of rolling process and die design. Deformation test and network test show the filling procedure of gear form and net change trend inside lead work-pieces respectively, so metal flow process and strain distribution of rotary forging are disclosed in spiral bevel driven gear. Force-stroke curve of rotary forging is measured and the key measures are put forward to avoid unfilled corner near the gear end. |
