Wheel hub bearing
The main function of hub bearing is to bear the weight and provide accurate guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component.
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, the enthalpy is generated from the maximum alternating shear stress below the contact surface, and then spread to the surface to form different flaking shapes, such as pitting or pitting. , peeling off 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.
