How casting the Gear?

    Also known as steel casting gear gears. 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 is usually from a few kilograms to several tons.
    Gear casting materials generally used carbon steel, some containing chromium, nickel, molybdenum alloy, in order to achieve a high tensile strength. Typically greater than that of the pinion gear physical requirements low.
About the casting process, usually on the floor molding process and to meet the normal requirements apply. As for steel gears, such as the driven gear, idler gear and using quartz sand floor molding process is a good choice. Why, because most of the parts of the gear machining is required. So, you do not need to use a higher casting process. Furthermore, regarding the large steel castings, the quartz sand on the floor molding process is almost the only choice.
    About the heat, of course, all steel castings must be standardized in order to eliminate the internal stress. Certain parts of the gear can be welded castings. If welding castings foundry, welding position must be annealed. If after hobbing high hardness, you can once again annealed to reduce the hardness and eliminates internal hard spot.    
   

China Gear

     After the processing and hobbing, gear quenching or so-called hardening treatment to improve the surface hardness of the gear teeth. For small gear, you can do carburizing treatment. For large driven gear, you can do surface hardening treatment. No hardened gear life is very short, only a few weeks to a few months.
   Since the gear castings of materials, defects, processing and heat treatment demanding. Furthermore, the gear casting a relatively small amount of orders. Thus, many steel manufacturers willing foundries.
   Some gear from the forging process. Forged Gears better internal tissue density, higher strength. Forged gear can be used for more stringent working conditions. Strong low casting gear, but widely used in general working conditions. Forged gear high cost, and relatively low cost casting gear. Buyer should be based on the cost and conditions of use choose the right manufacturing process.
