Product introduction
Gear forgings are mechanical parts produced through a forging process. They apply high temperature and high pressure to the metal blank to plastically deform it, thereby forming gear parts with specific shapes and sizes. They are widely used in the automotive industry, engineering machinery, mining equipment and aerospace. and other fields.
Product features
High Strength
The tensile strength of gear forgings usually reaches 1080MPa, and the yield strength can reach 930MPa, which is 20%-30% higher than the tensile strength (about 800MPa) and yield strength (about 600MPa) of cast gears. The increase in tensile strength makes the forged gear less likely to break when subjected to extreme tensile forces, while the increase in yield strength ensures that the gear does not deform during long-term high-load operation.
High Precision
The precision forging process allows the dimensional tolerance of gears to be controlled within ±0.05mm, while the dimensional tolerance of cast gears is usually between ±0.2mm and ±0.5mm, which is a significant difference. The concentricity deviation of forged gears is controlled within 0.01mm, while cast gears are usually 0.05mm or even higher. This increases gear meshing efficiency by 5%-8% and reduces noise and vibration.
Wear Resistance
Through surface carburizing and quenching treatment, the surface hardness of gear forgings can be increased to HRC58-62. Compared with gear forgings with untreated surfaces, their wear resistance is increased by about three times. In a 500-hour continuous high-intensity operation test, the wear rate of the forged gear was only 0.02mm, which is much lower than the 0.08mm of the cast gear.
