Abstract:  
Increased fatigue strength due to shot peening has been firmly established by extensive fatigue tests on a wide variety of machine parts. Although the process is used very extensively on leaf springs, coil springs, torsion bars and, in fact, practically every type of machine part, this paper is limited to its application for gears. Peening can be used not only to increase beam strength but also to increase pitting resistance. By utilizing the increased beam strength in design, improvement in noise characteristics has been achieved. It is likely that the same procedure can be employed to improve scoring resistance.
