We can use powder metallurgy technology to process the structure of the more complex gear, in the processing time should pay more attention, this situation requires different performance requirements for the workpiece to the appropriate choice of materials in order to ensure that the processing of the gear can get a higher strength The

When we use the powder metallurgy material blank for gear processing, it can increase its strength by about 10 percent. In addition, the precision of powder metallurgy production gear is related to the expansion coefficient of the material and the precision of the mold. So the diameter of the gear within the 50 domestic mold about eight, a little better for some of the imported mold seven. In this case, if the helical gear then the level will be higher. The biggest advantage of making the gear with powder metallurgy is the ability to produce in large quantities, with good uniformity.

Ordinary powder metallurgy gear products can generally withstand the equivalent of 14NM torque, for the temperature and pressure parts can reach 20NM. In the design of the time, if a full set of gears using professional powder metallurgy design, in the case of allowing modification, but also be able to reduce its quality by about 30 percent.
