Powder metallurgy gear parts are the most widely produced parts in powder metallurgy industry.
Powder metallurgy gear is the product of one-time net compression molding technology with less machining and inorganic processing. It is difficult to count powder metallurgy gear separately in the whole powder metallurgy parts, but according to the weight and number of parts, the proportion of powder metallurgy gear in automobiles, motorcycles, clocks and watches is much larger than that of sintered structural parts in other fields. Therefore, from the rising proportion of automobiles, motorcycles and clocks in the whole powder metallurgy parts, powder metal sintered gears are developing rapidly in the whole powder metallurgy parts. According to the characteristics of parts, gears belong to structural parts, and the use weight of structural parts in the whole iron based parts is also far greater than other types. We can say that it is the type with the largest proportion of production in powder metallurgy parts.

Types and applications of sintered gears in various industries
Powder metallurgy gear is a kind of powder metallurgy part widely used in various automobile engines. Through one-time forming and finishing process, it does not need other post-processing processes, and can fully meet the requirements of dimensional accuracy, especially the tooth profile accuracy. Therefore, compared with the traditional machining method, the material input and manufacturing are greatly reduced, which is a typical product reflecting the characteristics of powder metallurgy. Powder metallurgy parts ：automobile engine as an example. Camshafts, crankshaft timing pulley, pump rotors and gears, oil pump pulley, driving and driven gears, sprockets, camshaft parts, bearing covers, swing arms, bushings, thrust plates, valve guides, inlets, exhaust valve seats, various low-speed synchronizer hubs and components of automobile transmission gears, clutch gear bases, guide seats, compressors, various pistons, cylinder blocks, cylinder heads, valve plates, sealing rings, various sets, rotors Bearing: other gears, planetary gears, internal gears, composite internal gears, various stainless steel nuts, magnetic poles.
