With the development of the industrial technology industry, powder metallurgical gear is increasingly widely used in cars and motorcycles. For complex structural powder metallurgical gear gears, different gear materials can be used according to different performance requirements. So, what materials are commonly used in powder metallurgical gear?

1. For the impact load, the material with better toughness should be selected. The low -carbon steel carburizing quenching can be selected.

2. For high -speed closed transmission, the tooth surface is easy to eclipse, and the material with better hardness should be selected.

3. For low -speed mid -load, wheel teeth are broken, point erosion, and wear can occur, the mechanical strength, tooth surface hardness and other comprehensive mechanical properties should be selected. The carbon steel is selected.

4. When the structural size requires compactness and high abrasion resistance, alloy steel should be used.

The above is the introduction of what materials are commonly used in powder metallurgy gear. The working conditions of powder metallurgy gear are different and the destruction forms of wheel teeth are different. It is the basis for determining the strength of the gear strength and selection materials and thermal treatment.
