Solve the IKO spherical roller bearing burn correct lubrication method

Grease with the oxygen in air to produce acid chemical anti, first it is an antioxidant additive, the consumption of fat, but to a certain degree, the generation of organic acid corrosion of metal components and destroying the structure of fat, make its drop point drop, such as base oil viscosity increase and liquidity. A large number of tests show that the higher the temperature, the more obvious drop in the life of the grease. Such as temperature at 90 ~ 100 degrees, the temperature rise every 19 degrees, the service life of grease by about half, in 10 ~ 150 degrees, the temperature rise every 15 degrees, the service life of grease will be fallen by half. Free base refers to the soap grease is not too much with the effects of the fatty acids in the process of producing alkali; Free organic acid is in the process of manufacturing is not saponification of fatty acids, or hydroxyl fatty itself contains acid ( Naphthenic acid) Fat, or oil oxidation and saponification of middlings was breakdown products. Although you can install 'free' for all kinds of spherical roller bearing, seal, but the early failure of IKO bearing still has 36% is incorrect grease technology and improper use. Any improper lubrication of bearings in normal life inevitably fail to move forward. Machinery and equipment bearing is usually the most difficult part of the work, have no fixed lubrication will be a problem. Artificial maintenance, is impossible to achieve, the automatic lubrication system, can develop in order to achieve the best lubricating effect. Need grease, tools and effective lubrication technology, will help to significantly reduce downtime. IKO bearing parts in use under the influence of abnormal high temperature, cooling, without timely and will generate a high temperature tempering parts surface organization or secondary hardening phenomenon called burns. Burns, the main reason is poor lubrication, neck too much load, improper clearance improper selection, bearing configuration, raceway surface contact undesirable, such as stress caused by a cold. Such as; 1) In swimming axial bearing, if the external fit too tight, cannot move in casing hole; 2) Bearing in operation temperature, thermal expansion of the shaft causes large axial force, and the bearing can't axial movement; 3) Due to insufficient lubrication, or lubricant selection is not reasonable, quality problems, such as aging and deterioration; 4) Operation of internal cause and external cause temperature difference is big, improper selection and clearance external cause expansion of small internal cause big show interference lead to bearing temperature rise sharply; 5) Bearing the load is too large and uneven distribution of cutting load, form stress concentration; 6) Rough machining parts surface, resulting in poor contact or oil film forming difficulties. Burn appearance characteristics can be judged according to the color of the surface of the small with. Self-aligning roller bearing in use due to reasons such as lubricant, temperature, corrosion, parts surface changes, mainly with light yellow color, yellow, palm red, purple, blue and dark blue, light yellow, yellow, palm red chips in color ( See the related content) , if appear purple blue or bluish black action for burns. Burns easily cause the loss of parts surface hardness or a tiny grain. Burn the place mainly in parts of the contact surface, such as taper roller bearing guard working face, talk about child face, the stress concentration of the surface of the rolling, etc. Burn prevention according to the causes of burns a targeted action. Such as the right to choose IKO bearing structure and configuration, avoid spherical roller bearing with large installed load, when the right way to prevent stress concentration, ensure lubricating effect, etc.
