Brief description of common faults of rolling bearings
Due to various factors such as manufacturing process and operating environment of rolling bearings, common faults of rolling bearings are found in daily maintenance such as pitting, rolling, peeling, scratching, burning, thermal discoloration, corrosion, micro corrosion, dents, indentation, Strains, bumps, scratches, cracks, electric corrosion, etc.
The main factors affecting bearing performance are: bearing structure (shape, cage, internal shape); bearing quality (material, heat treatment, accuracy); lubricant (quality, quantity, type), seal (form, quality) and working environment.
① Pockmark: Scattered or clustered small pits on the surface of the part.
②Skinning: the phenomenon of extremely thin metal peeling on the surface of parts due to fatigue.
③Peeling: The phenomenon of metal flake peeling on the surface of parts under the cyclic action of high contact stress.
④Scratches: Metal migration phenomenon caused by sliding friction on the surface of parts.
⑤ Burning: hot-melt metal adhesion on the surface of the part.
⑥Thermal discoloration: The surface of the part is oxidized due to the increase in temperature.
