What Materials Are Commonly Used In Powder Metallurgy Gears?
Jan 28, 2019

1, for the impact load, the wheel teeth are easy to break should choose a more resilient material, you can choose low-carbon steel infiltration carbon quenching.
2, for high-speed closed-type transmission, the tooth surface is easy to point erosion, should choose the material with better hardness of the tooth surface, can use the surface quenching of medium carbon steel.
3, for low-speed mid-load, broken teeth, point erosion, wear can occur, should select mechanical strength, tooth surface hardness and other materials with good comprehensive mechanical properties, optional carbon steel quality adjustment cutting.
When the structure size is compact and the wear resistance is high, alloy steel should be used.
The above is the introduction of what materials are commonly used in powder metallurgical gears. The working conditions of powder metallurgical gears are different, and the damage forms of wheel teeth are different. It is the basis for determining the calculation criteria of gear strength and selecting materials and heat treatment.
