Gear rolling is a manufacturing technique for gears with many advantages like reducedmaterial consumption, reduced scrap generation, fast cycle times, good surface quality andimproved final properties of the gear wheels compared to conventional production technology basedon machining. In order to make use of all these advantages it is desired to reach the final shape ofthe gear wheel already after rolling. This means that post treatments like grinding should beavoided. This puts high requirements on the shape accuracy after gear rolling.In this paper it was studied if finite element simulation could be used to evaluate the shape accuracyafter gear rolling. The measurement of shape accuracy of gear wheels is specified in standards likeISO1328-1. The allowed deviations from nominal shape are often of the order of 10-30 μm for verygood qualities. So if such evaluation shall be possible from a finite element simulation the accuracymust be of the same order.In order to have sufficient accuracy of the finite element simulation 2D simulations were performedon a spur gear. The FE code DEFORM was utilized. The shape accuracy was evaluated for gearrolling of two cases. One case had gears with the module of 1 mm. The other case involved gearswith a significantly larger module of 4 mm. This was an interesting case since it is known that it ismore difficult to roll the gear with good accuracy in large modules.
