Bearing invalidation is a common problem in bearing operation, in which the wear mode is a type of bearing invalidation, and wear also has certain damage to bearings, such as a few pieces of processing will lead to bearing destruction and damage. Through the understanding of bearings, the Chinese nation bearing network shares these common ways of bearing wear. I believe that when you wear in the application of bearings, you can also carry out excellent recovery according to the actual way of wear.

1, air oxidation wear. The fine peaks and valleys in the relative movement surface of the bearing are oxidized with the air in the air to form the ductile metal oxide which is closely connected with the matrix metal and unstable. The metal oxide is easy to fall down in the friction, and the wear caused by it is called air oxidation wear.

2, friction heat wear. When the bearing works under the condition of heavy load and poor wetting, continuous high temperature, reduced strength and wear resistance of the contact surface, and even adhesion and tearing occur at the surface peak and valley because of friction. This type of wear is called tribological heat wear.

3. Abrasive wear. If the bearing is in relative motion. Bearing fitness appearance uneven mechanism, there are hard particles, or bearing movement between the appearance of falling into the sand, friction, cutting and other residues, bearing in relative motion, hard particles or residues will make the bearing appearance scratch and produce trenches, this kind of wear is called hard wear.

4, crack corrosion wear. Such as the reverse contact surface of transmission gear bearing, the relative link periodically suffers very large contact stress, long-term effect, metal material appearance fatigue, promote the bearing appearance of fine cracks and corrosion, this kind of wear is called crevice corrosion wear.
