Gears use a variety of materials, such as various cast iron, steel, powder metallurgy materials, non-ferrous alloys (such as copper alloys) and non-metallic materials can be used to produce gears. Steel is the most widely used material, including various low carbon steel, medium carbon steel, high carbon steel and alloy steel, etc.
There are many ways of gear heat treatment, such as normalizing and annealing, hardening and tempering, carburizing, nitriding, surface quenching, etc. The purpose is to improve the performance of steel material and the quality of gear processing, and extend the service life of the gear.
Compared with traditional flame hardening, induction hardening technology is a faster and more efficient heating process. ROCHO INDUCTION provides gear induction hardening systems, which are widely used in gears that require higher load capacity and smaller size. After hardening, the surface hardness of the gear tooth surface is high, and it will have strong pitting resistance and wear resistance; the core has good toughness, and the residual stress is generated, which greatly improves the tooth root strength.
