چکیده

The purpose of this research is to analyze the bevel gear forge process with finite element method by means of Super forge software and to compare it with the experimental results. Also a comparison between the microstructure of machining gears and forge gears after applying heat treatment on them is done. After committing the metallography experiments, we observe that the microstructure of forged gears has tinier martensites with short distances in gears surface, but machining gear has greater martensites with long distances.The obtained results show that the method of pieces production just before applying the heat treatment process will have a high effectiveness on the microstructure. Also, increasing in billet diameter that results billte’s heigh deduction, will cause pressure tonnage increasing. The obtained results of the simulation process show at the end of this paper.
