[0002] Powder metallurgy gears are difficult to count separately in the entire powder metallurgy parts, but whether by weight or by the number of parts, the proportion of powder metallurgy gears in various machinery, automobiles, and motorcycles is far greater than that of powder metallurgy parts in other fields. Powder metallurgy gears are the product of high-tech with less chips and no chips. Therefore, from the increase in the proportion of automobiles and motorcycles in the entire powder metallurgy parts, it can be seen that powder metallurgy gears are in a rapidly developing position in the entire powder metallurgy parts. If classified by the characteristics of the parts, gears belong to structural parts, and the absolute weight of structural parts in the entire iron-based parts is also far greater than that of other categories. Powder metallurgy parts, powder metallurgy gears are powder metallurgy parts commonly used in various automobile engines. Through a one-time forming and finishing process, no other post-processing processes are required, and the dimensional accuracy requirements, especially the tooth shape accuracy, can be fully met. Therefore, compared with the manufacturing method using traditional mechanical processing methods, the material input and manufacturing are greatly reduced. It is a typical product that embodies the characteristics of powder metallurgy.
