In product design, the hardness of the motor shaft is an important parameter, and whether the hardness is appropriate is directly related to the quality of the product.
The hardness of the motor shaft will be different due to the different materials, and the process selected during processing is different. The current common process includes the hardness of the raw material itself and the heat treatment process to increase the hardness.
Some products have a special structure, such as the need to be reinforced on the surface of the product, so the material of the motor shaft should not be too hard, and some motor shafts have circlips, so the hardness range of the motor shaft is between HV500-600. appropriate.
If the selected material of the motor shaft is SUS420 series stainless steel, the hardness range of HV260-320 is more appropriate.
But remember that the hardness of the motor shaft should not be too high. Sometimes the bearing capacity is not very high. Then the motor shaft can be tempered a little bit. For some parts with special requirements, it can be quenched and chrome-plated. .
