Generally, we use forged parts, steel bars, or cast parts with good toughness and ease of machining, often using forged parts.
First, the raw part is normalized to improve its machinability and roughing.
In the semi-finishing process, the gears are basically formed and then processed to obtain their mechanical properties. According to the requirements of the working conditions and the materials used, tempering and hardening, carburizing, and high-frequency induction on the tooth surface are used. Thermal hardening, nitriding, and other processes allow obtaining the mechanical properties that must be obtained under different working conditions.
Finally, the gears need precision machining.
Steel grades for different working conditions
Medium hardness gears (HB220-320): 40Cr, 42CrMo, 40CrNiMo, 38CrMoAl and other medium carbon alloy steels. Hardened gears (HRc56-62): 20CrMnTi, 20CrMnMo, 20CrNiMo, 20CrNi2Mo, 12CrNi3, low carbon alloy steels.
Nitriding gears: 25Cr2MoV, 38CrMoAl.
For large diameter teeth (D> 400-600 mm), cast steel tooth blanks cannot be forged; instead, cast steel tooth blanks can be used, generally ZG45, ZG 40Cr, ZG 42CrMo, ZG 40CrNiMo, ZG 38CrMoAl and other medium carbon alloy steels. The composition of the cast steel is equivalent to the chemical composition of the forged steel, with only an increase in Si content to 0.60-0.80%.
