In some papers "about gears" or "gears efficiency", the authors present an original method to determine the efficiency of the gear. The originality of this method relies on the eliminated friction modulus. One analyses the influence of a few parameters concerning gear efficiency. These parameters are: z1 - the number of teeth for the primary wheel of gear; z2 - the number of teeth of the secondary wheel of gear; alfa0 - the normal pressure angle on the divided circle; ßeta - the inclination angle.
With the relations presented, one can synthesize the gear’s mechanisms. Today, the gears are present everywhere, in the mechanical’s world (In vehicle’s industries, in electronics and electro-technique equipments, in energetically industries, etc…). Optimizing this mechanism (the gears mechanism), one can improve the functionality of the transmissions with gears; one save energy and one diminish the pollutions. If one increase theirs efficiency with one percent only, one obtains a very much economy of energy and one diminish substantially the noises, the vibrations and the emissions of noxious. The authors suggest an increase of the gears efficiency not only with one percent, but also with ten–twenty percents. In this mode one save more energy and one decrease substantially the pollutions.
