| Abstract: | Finite element analysis was applied to research the process of cool rotary forging for differential satellite gear of a car, the status of strain and stress, metal flow rule and force-time curve were obtained and the deformation mechanism of straight tooth bevel gear during cool rotary roll was revealed. The technology was researched experimentally on the rotary roll machine and the test samples with high dimensional accuracy and high surface quality were obtained. The result shows that finite element analysis is effective and satisfactory,the cool rotary forging for straight tooth bevel gear is reasonable and feasible. |
