A method for analyzing spur gear meshing is presented and applied. Analyzing the results of an example, it is shown that the path of contact and, in particular, the lowest (LPSTC) and the highest (HPSTC) single tooth contact points highly depend on profile modification amount and applied load. Furthermore, the root stress of a gear with profile modification reaches higher values than a gear with an involute profile. This increment is mainly due to an increase of the extension of the actual single tooth pair contact region of a modified gear with respect to the perfect involute gear.
