| Abstract: | Using finite element analysis for forming process and die structure of precision gear were introduced. Forward extruding for hollow pinion gear, compound extruding for housing gear and upending extruding for shaft gear and their forming conditions and processes were analyzed. Principle and methods of closed-forming for bevel gear and multi-motion distributaries for cylinder gear was introduced. Structure and hydraulic cushion of closed-die were stated. |
