INA bearings lubricants lubrication
At present, about 80% part of the damage is caused by friction and wear. Of course, you can reasonably choose pairing of frictional materials such as materials science methods to achieve reduced wear and achieve their goals through reasonable structure design, and reasonable lubrication can be an effective method for reducing friction. Lubrication is relative motion to each other using a material membrane surface is separated from this material caused by low shear resistance, wear a small. And lubricants in the INA played a major role in the transmission of the bearing is to reduce friction, reducing wear and tear, to extend the life of machine parts as much as possible. In addition, the lubricant also has a cooling, washing, sealing, rust protection, unloading, shock absorption, such as structural materials for additive carrier and the role.
Second, selection of viscosity
INA bearing lubricant viscosity is an important physical and chemical indicators, INA bearing the viscosity of meshing speed of selected key indicators. INA bearings suitable for lubricating oil viscosity, friction in the lubricant should be made small, resulting INA bearing surface wear and greatly reduces transmission noise, vibrations and other.
Viscosity of the lubricant is mainly achieved through the base oil and viscosity index improver. Lube base oil viscosity and molecular structure and molecular weight of about: higher average molecular weight, large viscosity of oil. As far as the base oil, mineral oil lubricants include lubricating oil, naphthenic base crude oil of paraffin base crude oil refining refining oil and base lubricating oil refining of crude oil in the Middle three. Paraffin base crude oil refining lubricating oil, its viscosity-temperature properties are better than the other two. Good viscosity index improver, requires not only the high viscosity, good shear stability, but also requires a good low temperature properties and thermal oxidation stability of. Poor shear stability of viscosity index improver, due to its main strand of polymers under shear stress and the molecular weight is reduced, and make the oil diluted in order to wear, such as fuel consumption impact series. On the same viscosity grades of lubricating oil, if using non-refined base oils and not very good viscosity index improver, though after provisioning you can reach a certain viscosity standards, but poor performance, such as viscosity-temperature, shear stability, also not up to the life cycle. Therefore, for low-speed heavy cement reducer, try to avoid using this type of lubricant, and choice of high quality advanced lubricants, base oil and viscosity index improver because it is better.
INA bearing lubricant viscosity greater, more protection against various damage to tooth surfaces, and therefore smaller INA bearing wear. Viscosity is too large to wear particles less precipitation, reduce the flushing effect of lubricating oil on the tooth surface and cooled endothermic effects, leading to poor lubrication. While entering meshing area of wear particles in suspension in oil, easy cause abrasive wear. In addition, the Ambassador spent driving resistance increases viscosity, tooth surface temperature to rise, increasing power consumption. In General, viscosity increases, a-level, energy consumption increased by about 1%~5%, and anti-emulsifying properties and stability of oil will decline. But high viscosity to reduce noise and prevent oil spills has obvious benefits. In addition non-uniform loads, regular started and work in a high temperature environment of equipment, the viscosity should be slightly higher.
