IKO roller bearing heating main causes analysis

Loss IKO bearings for many reasons, all the influence factors of design and manufacturing process will be associated with the loss of bearing, the analysis is bad judgment. But in general, generally can be used from the two aspects of factors and internal factors considered and analyzed. Loss of cylindrical roller bearing used factors mainly refers to install, use, maintenance, maintenance, repair and so on is in line with the technical requirements. Installation conditions is one of the primary factor of use factor, IKO bearings are often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and loss. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. In addition, analyze the grease and the surrounding medium, the atmosphere quality inspection is also very important. Local damage due to the operation or installation errors, a small number of bearing raceway and rolling element may be damaged. In running, rolled IKO bearing damaged parts will produce a particular vibration frequency. Vibration frequency analysis can identify the damaged bearing parts. In many applications, the applications of the vibration behavior of cylindrical roller bearing stiffness with the surrounding the stiffness of the same structure. Due to this feature, as long as the correct choice bearing ( Including the preload and clearance) And its application in the configuration, it is possible to reduce the application of vibration. 1. Bearing diameter of axle and bearing friction compatibility direct contact adhesive to avoid attacks and composition border smooth performance. Affect the friction pair friction compatibility of data element is: ( 1) As deputy information on metallurgical alloy difficulty levels. ( 2) Data and affinity to smooth agent. ( 3) As a deputy data in the condition of no smooth friction factor. ( 4) The microstructure of materials. ( 5) Thermal conductivity of materials. ( 6) Data can appearance size and characteristics of the oxide film. 2. Clamp into sexual information allows smooth agent foreign pliers and avoid scratch or hard particle ( And) Abrasive wear ability. For metallic materials with low hardness and elastic modulus, clamp in the sex is good, and the nonmetallic materials is not necessarily, carbon graphite, for example, low elastic modulus, but the clamp in the sex is bad. Cylindrical roller bearing usually use soft material and hard material forming friction, ordinary do bearing shell with soft materials. 3. Running-in IKO bearing in the process of the adaptation of the diameter of axle and bearing, reduce the diameter of axle and bearing shell processing error, alignment error, surface roughness parameter values, make contact with average, thereby reducing the friction and wear rate. 4. Friction compliance data on the surface of cylindrical roller friction appearance initial elastic-plastic deformation compensation to match the performance of the poor and shaft deflection. Low modulus of elasticity of material compliance is good. 5. Abrasion resistance into vice materials can resist abrasion. Under the condition of the rules of wear, wear rate or amount of wear, wear the reciprocal of abrasion resistance. 6. The fatigue resistance under cyclic load data can resist fatigue damage. The use of temperature, the strength of the bearing shell material, hardness, resistance to impact strength and organization average opposite tiredness is very important. Running-in, clamp into good data, usually poor fatigue resistance. 7. Corrosion resistant materials can resist corrosion. Smooth oil used in atmosphere will gradually oxidation, produce acidic substances, and in most smooth oil also contains extreme pressure additives, IKO bearing all corrosion data, therefore, cylindrical roller bearing information requirements have corrosion resistance. 8. Cavitation resistance motion state, the related to the liquid when the bubble in liquid solid appearance full break, a part of the impact high pressure or high temperature part, will cause cavitation and wear. Data against cavitation and wear can be referred to as cavitation resistance. Usually, the copper lead alloy, bearing alloy and aluminium zinc silicon alloy had good cavitation resistance. 9. The compressive strength of cylindrical roller bearings one-way load without being crushed or size can not change. Inspection on bearing surface should be clean before bearing, and then carefully check bearing oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace, and bad seal will cause damage to the bearing cloud caused by abnormal equipment downtime. Don't let check bearing IKO bearing exposure to pollutants or moisture environment. If the job is interrupted, should with oil film, paper or similar material by machine. If don't have to remove and may perform inspection of cleaning without masking of bearing, to clean with brush with petroleum solvent coating, then dry with a lint-free cloth or with compressed air to blow dry, Be careful not to let the cylindrical roller bearing component starting rotation) 。 With a little mirror, and the probe used in the similar to the dentist to check the bearing of the orbit plane, retainer and beads. Do not clean the encrypted block or dust bearing; You just wipe the outer surface. If the bearing is need to replace damaged situation. During regular maintenance downtime time replacement bearings than the array bearing damage of selected into a sudden stop loss is much more economical.
