Growing requirements on the running behavior and the load carrying capacity of heavy-duty gears and furthermore, the expanding techniques in the field of gear manufacturing are demanding suitable designing methods for tooth flank corrections. In order to calculate these corrections the spatial stress and deformation state in the mesh is determined based on the finite element method. Calculated examples of corrected helical gears show that even simple geometric modifications of the flanks which do not require advanced manufacturing methods can improve the gear characteristics so that an increased transferable power and a reduction in noise emission can be expected.
