Angular contact ball bearing noise is an important source of pollution of the environment, is also an important indicator of the angular contact ball bearing industry needs to control, especially for home appliances, office machinery, instrumentation fillet

Ball angular contact ball bearing noise limit is more prominent. Over the past years, China angular contact ball bearing industry in reducing angle contact ball bearing noise, do a lot of work, angular contact ball bearing noise reduction level very mention

However, compared with foreign countries, there is still a certain gap, users reflect the prominent "different tone" issues, namely the sudden sound of an irregular angular contact ball bearings operating, even

To scream. Angular contact ball bearing noise impact many factors, but also very complex, the overall design of angular contact ball bearings, angular contact ball bearing parts - the inner ring, outer ring, cage

, The rolling element and the lubricating oil (grease) to analysis, also requires from angular contact ball corner contact with the materials used in each part of the ball bearing, plus of -1-212 Art process even engineering using

Equipment, process materials to be analyzed. This angular contact ball bearing noise technology involved.

Scroll angular contact ball bearing corrosion causes and prevention of rolling angular contact ball bearing corrosion is caused by a variety of internal and external factors, summed up:

1, the metal surface finish (oxygen concentration cell corrosion).

2, the metal material itself, the chemical composition and structure.

3, in contact with the metal surface of the solution composition and the pH value;

4, the ambient temperature and humidity.

5, and the metal surface in contact with a variety of environmental media.

6, the other person′s sweat is caused by the angular contact ball angular contact ball bearing corrosion reasons, its pH 5 to 6. Therefore, in order to prevent hand sweating caused by corrosion, installation and production people

Members should bring gloves, it should not touch the rolling angular contact ball bearings.

Coated with anti-rust oil to prevent the roll angle contact ball bearings rust

1, soak method: some small rolling angular contact ball bearings soaked in rust oil, the oil film thickness control rust oil temperature or viscosity to achieve. To the surface

Adhesion layer of rust oil.

Brushing method: brushing attention evenly spread in the surface of the roll angle contact ball bearings, do not produce accumulation, we should pay attention coated to prevent leakage.

3, the 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.
