Abstract
This paper deals with the problem of determining the face load factors for spur gears. The authors propose a method used for determination of the correlation between the KHβ and KFβ factors, related respectively to load distribution due to contact and load distribution due to bending of the gear tooth. The proposed method allows to analyze deformation and stress in two dimensions, taking into account height and width of the gear tooth. The obtained results were compared with the ISO guidelines regarding the face load factors determination and then the regions of compatibility between the methods were analyzed.
