A bearing surface treatment
    1, the ion implantation processing techniques on the surface: the ion-implanted surface is some atoms of elements in ionized into a plasma and to accelerate it in the machine ten to several hundred kilovolts, the incident side in a higher speed An ion beam processing of the surface of the workpiece in the target chamber of vacuum technology.
Ion implantation technology Features: A significant improvement in wear resistance, corrosion resistance, high temperature resistance and light, electricity, superconductivity and other properties of the material; traditional surface alloy layer from equilibrium, solid solution alloying rules limit , in principle, any element (s) can be injected into any matrix metal; C, between the ion implantation layer and the base material is no interface, there is no combination of bad flaking; D, no environmental pollution.
Ion implantation techniques Applications: A, for tools, cutting tools, molds and other ion implantation, dramatically increase the life of the rolling body tooling B, for large bearing roller and the surface treatment of the steel ball, to obtain the desired high temperature, corrosion electromagnetic, self-lubricating characteristics, especially for large-size parts matrix may be relatively low price of materials, ion implantation is performed, to obtain the desired surface alloyed layer, to achieve the combination of high energy ion beam or a laser surface treatment technology required performance, parts manufacturing solve the overall material universal heat treatment or processing methods can not achieve.
2, the laser beam surface modification technology: laser beam surface modification technology is applied to the material surface high energy, so that the occurrence of physical and chemical changes can significantly increase the hardness of the material, strength, wear resistance, corrosion resistance and high temperature performance, etc., thus greatly improving product quality, extend product life and reduce costs exponentially, achieved tremendous economic benefits.
Laser beam surface modification technology advantages: A heat treatment depth is small and easy to control; B, the energy density of the laser spot can be accurately guided to the ground in different parts of the surface; C, after processing small deformation; D, easy to transport, switch and automatic control. E, chemical pollution, and help protect the environment. Laser surface modification transformation hardening, fused coating, alloying, amorphization and MICROCRYSTALLIZATION to, the impact of enhancement.
The laser beam surface modification technology applications: for rolling body surface modification, such as carbon steel ball after crossing chromium, surface-modified with a laser beam, the performance of the stainless steel balls can be obtained.
3, a physical vapor deposition (PVD) technologies: physical vapor deposition (PVD) technology is the use of thermal evaporation, ion sputtering or glow discharge, and other physical processes, the desired coating is deposited on the substrate surface technology. Physical vapor deposition coating the coating of metals, alloys, oxides, nitrides, carbides, etc.; film adhering ability, the process temperature is low, usually no or little deformation. Including vacuum deposition, ion sputtering, ion plating, etc..
Second, the assembly process
    Bearing installation must be cleaned before it? The bearing surface is coated with anti-rust oil, you must be carefully cleaned with clean gasoline or kerosene, and then coated with a clean, high-quality or high-speed high-temperature grease before installation. The cleanliness of the bearing life and vibration noise is very large. In particular, we want to remind you: fully enclosed bearings should be cleaned refueling.
How to choose the grease? The lubrication operation and service life of the bearings is extremely important. General principles: selection grease grease base oil, thickener and additives made of the grease performance of different types and different brands of the same type vary greatly different rotation limit allowed, important to note that in the choice. Grease performance is mainly decided by the base oil. Usually a low viscosity base oil suitable for low temperature, high speed; high viscosity suitable for high temperature, high load. Thickener also relates to the lubricating properties, the water resistance of the the water resistance decision grease thickeners. In principle, the different brands of grease can not be mixed, Moreover, even if the same kind of grease thickener, also with each other because of different additives adversely affect.
Grease lubricated bearings the better, lubricated bearings, grease as possible, this is a common misconception. The bearings and bearing indoor excess grease will cause excessive oil stirring, resulting in extremely high temperatures.
How to install and disassemble? Do not install directly hammering the bearing end face and non-bearing surface, the bearing force evenly briquetting, sleeve or other installation tools. If the mounting surface is greased, will install more smoothly. With the interference larger bearings should be placed in a mineral oil heated to 90 ~ 100 ℃ immediately after installation. Demolition difficulties, it is recommended that you use the removal tool to pull out the carefully poured the hot oil to the inner ring, the heat causes the bearing inner ring expansion, making it easier to fall off.
