Which gear has better performance, powder metallurgy gear or machined gear?

With the continuous development of industrial technology, powder metallurgy has become an indispensable equipment in industry. Which one has better performance than the machined gear? Let's get to know.

1： What is the hardness performance of powder metallurgy gear?

1: Ordinary atomized powder, with density above 6.9, and quenching hardness can be controlled to about HRC30.

2: Generally, the pre-alloyed powder (AB powder) has a density of more than 6.95, and the quenching hardness can be controlled to about HRC35.

3: High pre-alloyed powder (AE powder), density above 6.95, quenching hardness can be controlled to about HRC40

2： What are the advantages of powder metallurgy gears

1: The powder metallurgy gear itself has very good running-in performance, which can ensure lasting silence when used.

2. Compared with traditional gear hobbing process, powder metallurgy gear processing has obvious cost advantages and higher production efficiency.

3: The production cost of powder metallurgy gear is low, and it can be formed in one time. After forming, it is unnecessary to process the gear.

4: The utilization rate of powder metallurgy gear materials is high, which is very suitable for the utilization of steel resources.

5: The density and material of powder metallurgy gears are stable, and the tensile strength and compressive strength will be very good.

6: Powder metallurgy gear parts have good dimensional consistency, stability and high accuracy.

7: The powder metallurgy press forming (p/m) adopts die forming, which can achieve the machining of complex shape gears that cannot be made.

8: Powder metallurgy gears can be produced and processed in large quantities, which greatly reduces the production cost of gears and has higher efficiency.

To sum up, it is the performance advantages of powder metallurgy gears and machined gears shared by Zhongwei Xiaobian. If you want to know more about them, please pay attention to the official website of Zhongwei Precision.
