Shot peening is a kind of shot peening technology, which is different from shot peening cleaning. The purpose of shot peening cleaning is to remove oil stain, oxide scale, rust and machined burr on the workpiece surface. Shot peening strengthening of gear surface mainly relies on the impact of high-speed moving projectiles on the surface of parts to produce elastic-plastic deformation, resulting in favorable changes such as residual compressive stress, work hardening and fine structure, so as to improve the bending fatigue strength and contact fatigue strength of gears, and to reduce the anti-occlusion ability of gears. The noise of gears can increase the service life of gears by more than 50%.
