Finite Element Analysis on the Friction Effects in the Gear Rolling Process
2013 (English)In: NEWTECH 2013, 2013Conference paper (Refereed)
Gear rolling as a manufacturing method for gear wheels has a number of advantages in comparison with traditional gear production methods which makes it an interesting topic for scientific research. The main benefits are reduced material consumption, fast cycle time of the process, improved strength of the product due to the alignment of the microstructure during cold forming and a good surface quality.
There are several factors which can influence the process quality and accuracy of the geometry in the final state. One of the most important parameters is the friction between the tool and the blank during the forming process. Therefore it is of interest to study the effect of different friction models in finite element simulations to evaluate its effects on final gear wheel shape.
In this paper the shear friction model is studied. Two friction factors will be studied in this case. Two dimensional FE calculations will be performed with the code DEFORM. The results of the FE simulations and the effect of friction factor on gear flank and tip geometry are presented. One example is presented of the effect on the so called “rabbit ear “at the gear tip.
