Gear, three-level gear, special gear manufacturer

 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. Gear casting of high-carbon cast steel material commonly used single spur gears, some containing 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 a 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, using quartz sand floor molding process is almost the only choice. About three-level heat gear, 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 hobbing, gear or so-called quench hardening treatment to increase the surface hardness of the gear teeth. Pinion gear for electric curtains, 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. Moreover, 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. Green cutting process applied cutting fluid can improve tool life, improved surface quality and conducive to the discharge cutting heat without causing thermal deformation of the machine. However, in high-speed cutting process spatter and cutting fluid mist formed on the ecological environment, especially the health of particularly harmful to the operator. To this end, the processing area is usually closed with a cover up, install the oil mist separator, so just do not discharge oil mist, and the cutting oil flows back inside the machine recycling. But that does not fundamentally solve the environmental problem, because deterioration of cutting fluid replacement emissions will seriously pollute the environment. The cost cutting fluid and cutting fluid wet gear machining attachments consumed accounted for about 20 percent of processing costs, the use of high-speed dry cutting can be increased by 2 to 3 times more processing efficiency, wet cutting tool life is 2 to 5 times, so that the dry machining a single piece to reduce the processing cost of the gear. High speed dry cutting can reduce the cutting fluid consumption and cooling process equipment, avoiding pollution to the environment, but also improve productivity and reduce manufacturing costs one-piece gear. Therefore, high-speed dry cutting teeth become goals and direction processing machine manufacturer for many years after. With the high-speed, machine rigidity to improve gear cutting machines, and good vibration resistance and improve chip technology, as well as the further development of dry high-speed cutting tools, high-speed dry cutting has been fully implemented on the gear cutting machine tools.
