Nearly all models studying the dynamic of gearing with parallel axes are based on classical mechanical models and known which are studying the spinning vibration of shafts gears and determine their own beats and strains of shafts spinning. These classical dynamic models are very useful, but they didn't take in consideration the dynamic events formed between the two teeth in contact (or more pairs of teeth in contact). It's not seen the physiology of the mechanism itself with toothed gears. In this study we do not only account for the impact of teeth (collisions between teeth) but we also consider all the principal dynamic events that are occurring in top gear plane. This article will present an original model that explores the dynamic events originated and taking place in the plane geared couple of the parallel axes geared transmissions. The first measure to be taken for the protection of the environment of pollution of the over a billion motor vehicles with heat engines already in circulation, is to improve the motors and their drives.
