Gear Forgings

gear forging Introduce the product Gear is a gear on the rim of the transmission of continuous meshing motion and power mechanical components, is able to mesh with each other has a toothed mechanical parts, the diameter of the large gear is one times the diameter of the small gear.The application of gears in transmission appeared very early. In more than 300 BC, Aristotle, the ancient Greek philosopher, expounded the problem of transmitting rotating motion with bronze or cast iron gears in his "mechanical problems".At the end of the 19th century, the principle of the developed gear cutting method and the use of this principle of the special machine tool and tool have appeared, so that the gear processing with a more complete means, and with the development of production, the gear operation of the stability of attention.Mainly used in mining machinery, petrochemical, automobile manufacturing and other fields.The main material is 20CrMnTi 40Cr 42CrMo and so on. Product advantage Gear forging is the workpiece or blank obtained by forging and deforming the metal blank.The mechanical properties of metal billet can be changed by applying pressure to shape and deform it.Through forging, the porosity and holes of metal can be eliminated, and the mechanical properties of forging can be improved. Gear forging products are mainly used in mining machinery, petrochemical, automobile manufacturing and other industries, more than 90% of which are automobile forging, among which the cold and warm fine forging accounts for about 5.2% of the total forging.In 2004, the total output of forgings in China was about 3.26 million tons, including 2.44 million tons of die forgings, 65% of which were automobile forgings, 1.6 million tons, and 4-5% of which were cold and warm fine forgings.Forgings forged by the free forging method on the hydraulic forging press greater than 10MN are called large forgings. The production of large forgings has reached a certain scale and level.
