Abstract
The cold closed-die forging process of the gear is a kind of new technique of the
precise forming of gear in recent years. In this paper, the cold closed-die forging process of
differential satellite gear in car was analyzed through numerical simulation method. Forming mold
was designed with Pro/E Wildfire2.0 which included four components : upper punch, lower punch,
tooth shape upper die and lower die for Normal Cone. The three-dimensional models of satellite
bevel gear mould were built and imported into numerical simulation software DEFORM-3D.
Because the gear has the uniform circumferential features, in order to save time and improve the
accuracy, only one tooth was simulated, and the full simulation outcome of 10 teeth was mirrored
from this one. Through the numerical simulation analysis of DEFORM-3D, the instantaneous
deformation and stress filed were gained. Forming defects were forecasted and the cold closed-die
forging rule for satellite gear used in car was obtained which can provide effective references for
no-flash cold forging process of planet bevel gear and the mold design.
