What are the advantages of powder metallurgy gear?

As we all know, powder metallurgy gear in a variety of machinery, automobiles, motorcycles accounted for a much larger proportion than other fields of powder metallurgy parts. Powder metallurgy gear is widely used in all kinds of automobile engine powder metallurgy parts, through one forming and finishing process, do not need other post-processing technology, can fully reach the dimensional accuracy requirements, especially the tooth shape accuracy. Therefore, compared with the traditional machining method, the material input and manufacturing are greatly reduced, it is a typical product reflecting the characteristics of powder metallurgy. So what are the advantages of powder metallurgy gear? The following zhongwei precision Xiaobian for you to introduce:

Advantages of powder metallurgy gear:

1, low cost, high production efficiency, once forming, forming without processing gear teeth.

2, due to the processing characteristics of powder metallurgy, as oil-containing parts, can be no lubrication parts, but the effect is still slightly worse than oil bath lubrication, in the boundary lubrication state.

3, gear forming process without waste, good utilization of steel resources.

4, general powder metallurgy gear manufacturing process less.

5, with powder metallurgy manufacturing gear, the material utilization rate can reach more than 95%

6, powder metallurgy gear repeatability is very good. Because P/M gear is formed by die pressing, under normal service conditions, a die can press tens of thousands to hundreds of thousands of gear blanks.

7, powder metallurgy gear material density is controllable.

8. In powder metallurgy production, the roughness of the working surface of the die is very good in order to facilitate the release of the blank from the die after forming.

As mentioned above, in some unimportant mechanisms, toys and other powder metallurgy gears, precision drives, high torque drives and other gears that are still preferred for mechanical processing can be considered. The precision of gear made by powder metallurgy is not very high, but it is generally about 10 wires, which is not suitable for precision transmission.
