Ina bearing surface surface layer quality damper bearing manufacturers tell you

The failure modes of roller bearing include surface contact fatigue, abrasive particle damage, adhesion damage erosion damage. They have been produced in the surface surface layer of rolling bearing. It is obvious that the quality of surface layer is particularly important for the reliability service life of rolling bearing.

The scientific research on technological performance of roller bearing includes: surface appearance analysis; surface material surface mildew layer analysis; surface stress analysis; surface damage erosion analysis.

Because of the harm of cold heat treatment standards wetting materials, the external economic organization structure, physics, organic chemistry physical properties of the surface layer of INA Bearing are usually very different each other. The surface layer of rolling bearing whose external economic structure, physics, organic chemistry physical properties have changed is called surface mildew layer. If the surface mildew layer is caused by cutting production process, it is called cutting surface mildew layer. The analysis of mildew layer on the surface of roller bearing of automobile European shock absorber bearing is the key component of rolling bearing process performance analysis, is also one of the key components of rolling bearing failure description.

According to the formation principle of surface cutting mildewy layer in rolling bearing work, the key factors that harm the mildewed layer are cutting heat cutting force.

1. Cutting heat

In the cutting production processing, the wholesale of domestic shock absorber bearing consumes a lot of energy in the contact area between sand wheel piece product workpiece, resulting in a lot of cutting heat, resulting in part of the instantaneous high temperature in the cutting area of European damping bearing suppliers. The instantaneous temperature of the cutting zone can reach 1000-1500 ℃ within 0.1-0.001ms by calculating calculating the instantaneous temperature under the test standard by using the basic theoretical formula of pyrogen heat conduction of strip-shaped fitness exercise by using infrared induction method thermal resistance method to evaluate the test standard. Such instantaneous high temperature can make the deep surface of the working surface cause high temperature air oxidation, amorphous structure, high temperature quenching, secondary heat treatment, even scald cracking other changes.
