Usually we use forgings, bar stock, or casting with good toughness that are easy to machine, often using forgings.
First normalizing the rough part to improve their machinability and roughing.
In the semi-finishing process, the gears are basically formed, after which they are processed to obtain the mechanical properties of the gears. According to the requirements of the working conditions and the materials used ,the quenching and tempering, the carburizing quenching, and the tooth surface high-frequency induction are used. Heat quenching, nitriding and other processes make it possible to obtain the mechanical properties that should be obtained under different working conditions.
Finally, the gears need precision machining.
Steel grades for different working conditions
Medium hard gear (HB220-320): 40Cr, 42CrMo, 40CrNiMo, 38CrMoAl and other medium carbon alloy steels.
Hardened gear (HRc56-62): 20CrMnTi, 20CrMnMo, 20CrNiMo, 20CrNi2Mo, 12CrNi3, low carbon alloy steel.
Nitriding gears: 25Cr2MoV, 38CrMoAl.
For large diameter (D> 400-600mm) tooth blanks can not be forged, cast steel tooth blanks can be used, generally used ZG45, ZG 40Cr, ZG 42CrMo, ZG 40CrNiMo, ZG 38CrMoAl and other medium carbon alloy steel. The steel composition of the cast steel is equivalent to the chemical composition of the forged steel and only increases the Si content to 0.60-0.80%.
Standard wear-resistant material with excellent impact resistance and work hardening properties.
Enhanced wear resistance with embedded alloy bars for superior performance in high-abrasion conditions.
Advanced ceramic composite matrix reinforcement technology for extended service life.
Bimetal composite structure combining wear-resistant surface with tough core material.
Excellent wear resistance with good hardness retention at elevated temperatures.
Rebuilding and reinforcement using advanced hardfacing welding technology.
Customized according to your operating conditions
For highly abrasive materials such as limestone and sandstone, we adopt high-chromium cast iron or ceramic composite materials, which extend the service life by 3 to 5 times.
For high-impact materials like construction waste and metal ores, we adopt a reinforced structure with high manganese steel and alloy bars, delivering excellent impact resistance.
For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
We will fully understand your working conditions and recommend the most appropriate material selection. Provide drawings based on your machine models and spare parts dimensions.
