How to improve the broken tooth strength of powder metallurgy gears?
How to improve the broken tooth strength of powder metallurgy gears? With the development of science and technology, many equipment are more and more widely used in industry. Powder metallurgy is one of them. So how to improve the broken tooth strength of powder metallurgy gears? Let's follow zhongwei to have a look.
Powder metallurgy gear is the product of high and new technology with less chips and no chips. It is difficult to count powder metallurgy gears separately in the whole powder metallurgy parts, but the proportion of powder metallurgy gears in automobiles and motorcycles is far greater than that of powder metallurgy parts in other fields, whether by weight or by the number of parts.
1. If the gear is processed with powder metallurgy blank, the strength will be about 10% higher.
2. The common powder metallurgy gear (density 6.8-7.0) can carry a torque of 14NM (refers to locked-rotor), and the warm compaction parts can reach 20NM. If the warm compaction powder metallurgy gear can reach about 25, the mild degree can also be increased by 30-40% when the full set of gear is designed by professional powder metallurgy to allow modification.
3. The precision of powder metallurgy gear depends on the material expansion coefficient and mold precision. Generally, the domestic mold of gear with diameter less than 50 is about 8-9, and the imported mold is 7-8. If the helical gear is a higher level. The biggest advantage of P/M gears is that they can be produced in batches with very good consistency.
To sum up, it is how to improve the strength of broken teeth of powder metallurgy gears. I hope this article will help you. If you want to learn more, please pay attention to the official website of zhongwei Precision
