Bearing failure mechanism


1. Contact fatigue failure


Contact fatigue failure refers to the failure of the working surface of the bearing subjected to alternating stress. Contact fatigue spalling occurs on the bearing working surface, often accompanied by fatigue cracking, first from the maximum alternating shear stress below the contact surface, and then extended to the surface to form different peeling shapes, such as pitting or pitting. Peeled into small pieces called shallow peeling. Due to the gradual enlargement of the exfoliation surface, it tends to expand deeper and form deep exfoliation. Deep exfoliation is the source of fatigue in contact fatigue failure.
