Abstract. Gears are integral to many mechanical systems, including industrial machinery and automotive transmissions. Subject to significant mechanical and tribological stresses from rotational forces and torque transmission, gears often face challenges like surface wear and fatigue. Enhancing the durability and performance of gears is therefore vital, and this is where manufacturing processes such as Machine Hammer Peening (MHP) come into play. As an incremental forming process, MHP has the potential to substantially increase the mechanical and tribological load capacities of gears. The objective of this study is to assess how MHP can enhance the surface characteristics of case-hardened 16MnCr5 (1.7131) gear analogue shafts, focusing on the reduction of surface roughness and the increase in surface hardness. Such improvements contribute to improved wear resistance, which can significantly extend the lifespan of the gears, ensuring more reliable performance in demanding operational conditions.
