A Finite Element Analysis for the Forging Process of Hollow Spur Gear

Abstract:

The process of precision gear forging has been developed recently because of its advantages of giving high production rates, improved strength and surface finish. For complete filling up, predicting the power requirement is an important feature of the forging process. To analyze the process of incremental forging of hollow spur gear forms from initially ring-type specimens, a series of simulations using the program DEFORM-3D was carried out. The results of current simulation were compared with the experimental data those obtained by forging of hollow spur gear forms. In addition, the influences of the process parameters such as module, number of teeth, the ratio of the inner radius to the outer radius, friction factor and the height of the billet on the forging force is also examined.
