Many factors bearing noise impact is also very complex, research also needs to analyze the overall design of the bearing, each bearing parts - the inner ring, outer ring, cage, rolling element and lubricants (grease) from the bearing every a part of the material, plus of -1-212 arts process even works, equipment, process materials to be analyzed. This bearing noise technology.
Rolling bearings causes and prevention of corrosion Rolling corrosion is caused by a variety of internal and external factors, summed up:
1, the metal material itself chemical composition and structure.
2, the metal surface finish (oxygen concentration differential cell corrosion).
3, ambient temperature and humidity.
4, in contact with the metal surface of the solution composition and the pH value;
5, and the metal surface in contact with a variety of environmental media.
6, another human sweat also lead bearing corrosion reasons, its pH value is 5 to 6. So, in order to prevent corrosion caused by hand sweat, installation and production personnel should wear gloves, it should not touch the rolling bearing.
Bearings coated with anti-rust oil to prevent rolling bearing rust
Brushing method: Brush Note evenly coated in the bearing surface, do not produce accumulation, we should pay attention coated to prevent leakage.
Spray method: some large rust-proof material not suitable for oiled soak method generally about 0.7Mpa pressure filtered compressed air in place of the air cleaning spray. Spray method applies the solvent dilution rust oil or a thin layer of anti-rust oil. Such methods must be adopted to improve fire safety and labor protection measures.
Soak method: some small Rolling soaked in rust oil, the oil film thickness control rust oil temperature or viscosity to achieve. Its surface adhesion layer antirust oil.
