Powder metallurgy materials can improve the strength of gear parts

Powder metallurgy gears are in a rapidly developing position in the entire powder metallurgy parts. The powder metallurgy gears used in automobiles and motorcycles are much larger than those in other fields. Powder metallurgy materials can improve the strength of gear parts, so powder metallurgy gears are most widely used in powder metallurgy parts.

When powder metallurgy technology is used to process gears with complex structures, more attention should be paid when processing. In this case, materials must be appropriately selected according to the different performance requirements of the workpieces to ensure that the processed gears can obtain higher strength.

When using the powder metallurgy material blank for gear processing, its strength can be increased by about 80%. In addition, the accuracy of powder metallurgy production of gears is related to the expansion coefficient of material processing and the accuracy of the mold. Therefore, the domestic mold for gears with a diameter of less than fifty is about eight grades, and the imported molds are slightly better for seven grades. In this case, if it is a helical gear, the grade will be higher.

The biggest advantage of using powder metallurgy to make gears is that they can be produced in large quantities and have good uniformity. Ordinary powder metallurgy gear products generally can withstand a torque equivalent to 12NM, and for warm-pressed parts it can reach 20NM. When designing, if a complete set of gears adopts professional powder metallurgy design, in the case of design modification, it can also reduce its quality by about 30%.

Powder metallurgy gears are in a rapidly developing position in the entire powder metallurgy parts. If divided according to the characteristics of the parts, gears are structural parts, and the absolute weight of structural parts in the entire iron-based parts is far greater than other types of powder metallurgy parts.
