There are many reasons for the loss of iko bearings. All the influencing factors of the design and manufacturing process are related to the loss of bearings, and it is not easy to judge by analysis. But in general, it can be considered and analyzed from two aspects: usage factors and internal factors. The use factors of the lossy cylindrical roller bearing mainly refer to whether the installation adjustment, use and maintenance, maintenance and repair, etc. meet the technical requirements. The installation condition is one of the primary factors in the use factor. The iko bearing often changes the force state between the parts of the whole set of bearings due to improper installation, and the bearing runs and wears out in an abnormal state. According to the technical requirements of bearing installation, use, maintenance and maintenance, monitor and check the load, speed, working temperature, vibration, noise and lubrication conditions of the running bearing, find the cause immediately, and make adjustments to make it Back to normal. In addition, it is also important to analyze and test the quality of the grease and the surrounding medium and atmosphere. Local damage Small parts of the bearing raceways and rolling elements can be damaged due to handling or installation errors. During operation, rolling over damaged iko bearing components generates specific vibration frequencies. Vibration frequency analysis identifies damaged bearing components. Vibration Behavior in the Application In many applications, the stiffness of a cylindrical roller bearing is the same as the stiffness of the surrounding structure. Because of this feature, it is possible to reduce vibration in the application as long as the bearing (including preload and clearance) and its configuration in the application are properly selected. 1. Friction compatibility: When the bearing shaft diameter is in direct contact with the bearing shell, it can avoid adhesion and form a smooth boundary. The data elements that affect the friction compatibility of the friction pair are: (1) The difficulty level of metallurgical alloy composition of the pair material. (2) The affinity of materials and lubricants. (3) The friction factor of the paired material in a non-smooth state. (4) Microstructure of data. (5) Thermal conductivity of the material. (6) The size of the surface energy of the material and the characteristics of the oxide film. 2. Clamping ability The material allows the foreign hard particles in the lubricant to be clamped to avoid scratches or (and) abrasive wear. For metal materials, those with low hardness and low elastic modulus have good clamping properties, while non-metallic materials are not necessarily, such as carbon graphite, which has a lower elastic modulus but poor clamping properties. Cylindrical roller bearings usually use softer materials and harder materials to form the friction width, and generally use softer materials as bearing bushes. 3. Run-in performance iko bearings have the ability to reduce the machining error, coaxiality error and surface roughness parameter values ​​of the shaft diameter and the bearing pad during the running-in process of the shaft diameter and the bearing pad, so as to make the contact even, thereby reducing the friction force and the wear rate. 4. Frictional compliance The material relies on the elastic-plastic deformation of the surface to compensate for the poor initial fit of the cylindrical roller friction surface and the deflection performance of the shaft. Materials with low elastic modulus have better compliance. 5. Wear resistance The ability of the auxiliary material to resist wear and tear. Under regular wear conditions, the wear resistance is expressed by the wear rate or the inverse of the wear degree and the wear amount. 6. Anti-fatigue The ability of the material to resist fatigue damage under cyclic load. At the operating temperature, the strength, hardness, impact strength and structural uniformity of the bearing material are very important to fatigue. Materials with good run-in and clamp-in properties usually have poor fatigue resistance. 7. Corrosion resistance The ability of the material to resist corrosion. When the lubricating oil is used in the atmosphere, it will gradually oxidize and produce acidic substances, and most lubricating oils also contain extreme pressure additives, which will corrode the iko bearing material. Therefore, the cylindrical roller bearing material needs to have corrosion resistance. 8. Cavitation resistance In the state where the solid is related to the movement of the liquid, when the bubbles in the liquid rupture near the surface of the solid, some impact high pressure or some high temperature will be generated, which will lead to cavitation wear. The ability of a material to resist cavitation wear is called cavitation resistance. Generally, copper-lead alloys, bearing alloys and aluminum-zinc-silicon alloys have better cavitation resistance. 9. Compressive strength The ability of cylindrical roller bearings to accept unidirectional loads without being crushed or dimensionally unchanged. Before inspecting the bearing, the surface of the bearing should be cleaned first, and then the oil seal of the bearing and its surrounding parts should be carefully checked. If there are bad symptoms, be sure to replace it. The bad oil seal will cause damage and make the bearing cloudy. normal equipment downtime. Do not expose the iko bearing to contamination or moisture when inspecting the bearing. If work is interrupted, cover the machine with oil-paper-plastic sheets or similar materials. If cleaning unshielded bearings without disassembly and inspection possible, use a coating brush dipped in petroleum solvent to clean them.Then dry with a lint-free cloth or blow dry with compressed air (be careful not to allow the cylindrical roller bearing assembly to start spinning). Use a small mirror and a probe similar to that used by a dentist to inspect the bearing raceways, retainers and beads. Covered or dust-tight bearings should not be cleaned; just wipe the outer surface. If the bearing is damaged, it needs to be replaced. It is far more economical to replace the bearing during a regular downtime than the loss of a sudden downtime due to damage to the array.
