Study on Influencing Factors of Tooth Forming Quality for Gear Shaft with Cross Wedge Rolling

Abstract:

The feature of the gear shaft with Cross wedge rolling technology is high efficiency, low material loss and higher strength of the gear shaft forming. A research model of cross wedge rolling plastic forming adopting tri-dimensional thermal elastic-plastic finite element method is put forward. Forming mold divided into two parts as the wedge-shaped molds and tooth mold is designed. Depending on orthogonal test program, applying Deform-3D to numerical simulate for the gear shaft with cross wedge rolling, the influence of temperature, number of teeth, module and feet rate for gear shaft tooth forming quality is studied. The results are analyzed with the temperature of the workpiece, number of teeth, module and feet rate of the die movement during CWR and the best combination of produce conditions is reached.
