First, if the powder metallurgical rough processing gear is used, the definite strength will be about 10 % higher;
Second, the accuracy of powder metallurgical gears depends on the expansion coefficient of the material and the precision of the mold. Generally, the diameter of the gear is about 8-9, and the imported mold is 7-8, if the Bevel gear is one higher. The biggest advantage of powder metallurgical gear is that it can be mass-produced and its consistency is very good;
Third, ordinary FN0205 powder metallurgical gears can carry torque of up to 14NM, thermal pressure parts can reach 20NM, if the temperature pressure FD0405 can reach about 25, in the case of a full set of gears using professional powder metallurgical design allowed repair, Mild can also increase by 30-40 %.
The above is a description of the strength of the powder metallurgical gear described today. The powder metallurgical gear is a powder metallurgical part commonly used in various automotive engines. After a single forming and finishing process, no other reprocessing process is required. Can fully achieve the dimensional accuracy requirements, especially the tooth shape accuracy.
