Abstract:  
Abstract Damage on gears is mainly due to fatigue in fillet radii of teeth roots or pitting near the pitch diameter. No to little available articles in existing literature clearly show the influence of main shot peening parameters on life time of shot peened gears. Furthermore most available articles are devoted to fatifue in fillet radii which seems to be the most important factor of field failure. This paper is based on a bibliographical research and tries to gather all pertinent information conceringin the main shot peening parameters that could be used to determine the characteristics of a shot peening applied on a gear.
