The tooth height of CVT PULLEY SHAFT is 5 and the tooth width is 39, 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.
