Gear castings are also known as cast steel gears. This is because most gears are made of cast steel. Here I share some information about the production of gear castings and related heat treatment. Gear castings usually range in weight from a few kilograms to several tons.
Gear castings are usually made of high carbon cast steel, but some are made of alloy steel containing chromium, nickel and molybdenum to achieve high tensile strength. Large gears generally have lower physical requirements than pinions.
About the casting process, usually the floor molding process is suitable and can meet the normal demand. For cast steel gears, such as driven gears, gears and idler wheels, a floor molding process using quartz sand is a good choice. Why? Because most parts of the gear need machining. So, you don't need to use a higher casting process. In addition, for medium and large steel castings, the floor molding process using quartz sand is almost the only option.
Regarding heat treatment, of course, all steel castings must be standardized to eliminate internal pressures. Some parts of the gear casting can be welded. If the foundry welds castings, the weld position must be annealed. If the hobbing is extremely hard, you can anneal again to reduce the hardness and eliminate internal hard spots. After machining and hobbing, a gear is hardened or hardened to improve the surface hardness of its teeth. For pinion gear, you can do carburizing. For large driven gears, you can do surface hardening. Gears that have not been hardened have a short life span of only a few weeks to a few months.
Because gear castings have higher requirements on materials, defects, processing and heat treatment. Moreover, orders for gear castings are relatively small. As a result, many steel foundries are reluctant to manufacture.
Some gears are made by forging process. Forging gear internal tissue density is better, higher strength. Forged gears can be used for more stringent working conditions. Cast gears have low strength but are widely used in general operating conditions. The cost of forging gears is high while the cost of casting gears is relatively low. The buyer shall select the appropriate manufacturing process according to the cost and conditions of use.
