Powder metallurgy gear is a high-tech product with less and no chips.
Although it is difficult to count powder metallurgy gears separately in the entire powder metallurgy parts, the proportion of powder metallurgy gears in automobiles and motorcycles is far greater than that of powder metallurgy parts in other fields, regardless of weight or number of parts. 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 rapid development position in the entire powder metallurgy parts. If divided according to the characteristics of the parts, gears belong to structural parts, and the absolute weight of structural parts in the entire iron-based parts is far greater than other types, powder metallurgy parts.
Main powder metallurgy gears
(1) Camshaft toothed belt wheel Camshaft toothed belt wheel is a powder metallurgy part commonly used in various automobile engines. Through one-time forming and finishing process, no other post-processing processes are required, and the dimensional accuracy requirements can be fully met. Especially the tooth profile accuracy. Therefore, compared with the traditional mechanical processing method, the material input and manufacturing are greatly reduced. It is a typical product that reflects the characteristics of powder metallurgy. Examples of supporting powder metallurgy parts
