| Abstract: | In the paper, the deformation characteristics of ring rolled workpiece with stepped hole are discussed first, based on the strain state of the cubic element in deformed zone, revealed from the grid test of ring rolling on a lead specimen of automotive bevel gear. Then, the design of roll calibre and preform for ring rolling are described and calculation examples of power and energy requirement are given. Finally, the situation of applying ring rolling technique to the production of automotive bevel gears is expounded and the economic and technical comparision between ring rolling and conventional die forging is also made. |
