Abstract：

For planetary spur gear in truck wheel redactor, a forward extrusion technology was developed. In order to achieve better technological parameters, their multi-objective optimization was carried out by the FEM method and orthogonal experiment. For the evaluation index of the maximum forging load, the height of gear sunk angle, the maximum damage value of forging workpiece and mould wear, the influences of die-entrance angle, die working length, blank diameter coefficient, extrusion speed and friction coefficient on forming result were studied. Furthermore, the optimal value of the significant factors was determined by comprehensive balance method with the die-entrance angle 35°, the blank diameter coefficient 1.20 and the extrusion speed 70 mm·s-1. After the technological experiment, the qualified planet gear could be manufactured by the optimized forward extrusion.
