Analysis of the treatment of different materials of sprockets and gears

ProductionSprockets, ,GearThe materials used are generally grey cast iron, low carbon steel, medium carbon steel, low carbon alloy steel, medium carbon alloy steel, etc. according to the application. (HT20-40, HT25-47, HT30-54, 45# steel, 40Cr, 40MnB, 15, 20, 20Cr, 18CrMnTi, 35CrMo) The heat treatment of gears made of gray cast iron is stress relief annealing, gears made of low carbon steel are carburizing quenching, gears made of medium carbon steel are high frequency quenching, some are medium temperature tempering, and some is low-temperature tempering. In short, different materials with different heat treatment methods, so that gears, sprockets with high surface hardness and wear resistance, good toughness of the heart, to achieve the purpose of good impact resistance.
