 Commonly used in the manufacture of steel gear materials have quenched and tempered steel gears, hardened steel, carburizing and nitriding steels hardened steel. Strength cast steel forgings slightly lower than the commonly used in larger size gear; the poor mechanical properties of gray cast iron can be used for light load of open gear drive; ductile iron may be partially replaced by steel gear; multi-use plastic gears at light load and low noise requirements where the gear is generally paired with good thermal conductivity of steel gears. Future gear forward overloading, high speed, high precision and high efficiency, direction, and seeks small size, light weight, long life, and economic and reliable. And the development of theory and gear manufacturing process will be further studied the mechanism of tooth damage, the intensity of which is to establish a reliable basis for calculation is to increase the carrying capacity of the gear to extend the life of the theoretical basis of gear; the development of arc tooth profile as a representative The new tooth; research of new materials and manufacturing gear gear new technology; the elastic deformation of gear, manufacture and installation errors and the distribution of temperature field, perform tooth modification to improve the smooth running gear and at full load When increasing the contact area of ??the tooth, thereby improving the carrying capacity of the gear. Friction, lubrication theory and gear lubrication technology is the basis for the study work, study elastic hydrodynamic lubrication theory, promote the use of synthetic lubricants and extreme pressure additives added as appropriate in oil, not only can increase the carrying capacity of the tooth surface, and also can improve transmission efficiency. Gear Gear casting cast steel casting is also known as a gear. This is because most of the gears are made of cast steel. Here, I share some of the production gear castings and heat-related information. Gear casting weight generally ranging from a few kilograms to several tons. The casting material is usually used a gear-carbon steel, containing some chromium, nickel, molybdenum alloy steel, in order to achieve a high tensile strength. Usually lower than the physical needs of the large gear and the pinion. About casting process, usually on the floor molding process and to meet the normal requirements apply. As for the cast gear, such as the driven gear, idler gear and the use of quartz sand floor molding process is a good choice. Why, because most of the parts of the gear will require processing. So, you do not need to use a higher casting process. In addition, on medium and large steel castings three-level gear, using quartz sand floor molding process is almost the only choice. About heat, of course, all steel castings must be standardized in order to eliminate the internal pressure. Some parts of the gear can be welded castings. If the foundry welding castings, welding position must annealing. If hobbing high hardness, you can re-annealed to reduce the hardness and eliminates internal hard spot. After processing and industrial gear hobbing factory outlets, gear hardening or so-called hardened gears, in order to improve the surface hardness of the gear teeth. For small gear, you can do carburizing. For large driven gear, you can do surface hardening treatment. No hardened gear life is very short, only a few weeks to several months. Due to the higher gear of the casting defects in material, processing and heat treatment requirements. And special gear manufacturers, orders gear castings relatively small. Therefore, many do not want to manufacture steel foundries. Some gear manufactured by the forging process. Forging better gear internal tissue density and higher strength. Forged gear may be used for more stringent working conditions. Strong low-grade casting gear, but widely used in general working conditions. High cost of forging gears, and the gears of casting costs are relatively low. The purchaser shall select the appropriate manufacturing process based on cost and conditions of use.
