Heat treatment changes the physical properties, such as surface hardness, which gives the ability to prevent simple wear of the teeth and bearing surfaces; heat treatment also changes the fatigue life of the gear by creating subsurface compressive stress to prevent pitting and corrosion caused by high contact stress on the gear teeth. out of shape.
Reasonable processing of bevel gears is very important, and heat treatment is a very important step in the process of bevel gear processing, so what effect does heat treatment have on bevel gears?
Heat treatment changes the physical properties, such as surface hardness, which gives the ability to prevent simple wear of the teeth and bearing surfaces; heat treatment also changes the fatigue life of the gear by creating subsurface compressive stress to prevent pitting and corrosion caused by high contact stress on the gear teeth. out of shape. These same compressive stresses prevent fatigue failure at the gear root due to cyclic bending.
Heat treatment is a critical and complex factor in gear manufacturing, affecting each gear's ability to transmit power or motion to other components in the assembly. Heat treatment optimizes performance and extends the life of gears in service by altering their chemical, metallurgical and physical properties. These characteristics are determined by considering the geometry of the gear, power transmission requirements, stresses at various points within the gear under load, load cycle rates, material type, mating component design and other operating conditions.
Therefore, heat treatment of bevel gears can have good performance and meet people's production needs.
