The wear failure refers to the failure of the relative sliding friction between the surfaces due to the surface of metal wear and the. Continuous wear will cause LUNRICATION AND OIL FOR 23048 CCK/W33 damage to bearing parts gradually, and eventually led to the loss of precision bearing size and other related issues. Wear may affect the shape change, increased clearance and surface morphology changes, may affect the lubricant or its pollution to a certain extent and cause lubrication complete loss of function, and thus loss of bearing rotation accuracy and can not operate normally. Wear failure is one of the common failure mode of bearings, according to wear form is usually divided into the abrasive wear and adhesive wear the most common.
Abrasive wear is refers to between the flange bearing working surface in contact surface debris and moving relative to foreign hard particles or hard foreign bodies or metal surface caused by wear, abrasion often cause furrow shaped in LUNRICATION AND OIL FOR 23048 CCK/W33 bearing working surface. The hard particles or foreign matter may come from the host or from the host system to other adjacent parts inside the bearing lubrication medium by. Adhesive wear due to the friction surface refers to micro convex or foreign body so that the friction surface uneven force, the lubrication condition deteriorated, due to local friction, easy to cause the friction surface of local deformation and friction micro welding phenomenon, serious when may partially melted metal surface, the contact surface on the acting force of the local friction welding point tear from the matrix and increase the plastic deformation. The circular process adhesive -- tear -- adhesion adhesive wear, which in general, mild adhesive wear called abrasions, severe adhesive wear called occlusion.
The main reason of failure is the flange bearing defects and overload are two major factors. When the load exceeds the limit strength of the material as a result of parts breaking overload fracture. Overload causes the main host of sudden failure or improper installation. LUNRICATION AND OIL FOR 23048 CCK/W33 bearing parts of the micro cracks, shrinkage, bubbles, large foreign materials, organizations and local overheating burn defect in defect caused by fracture in severe shock or vibration overload also, known as the defect fracture. It should be noted, bearing in the manufacturing process, the raw materials into the factory inspection, forging and heat treatment quality control, process control equipment can be correctly analyzed by the existence of the defect, the control must be strengthened in future.
