INA bearing heating main causes of universal joint is analyzed

Loss INA gimbal bearings for many reasons, all the influence factors of design and manufacturing process will be associated with the loss of bearing, analysis and bad judgment. But in general, generally can be used from the two aspects of factors and internal factors considered and analyzed. Loss of INA bearings of universal joint use 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, INA gimbal 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. 1. Bearing diameter of axle and bearing friction compatibility direct contact adhesive to avoid attacks and composition border smooth performance. 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. INA gimbal bearings usually use soft material and hard material forming friction, ordinary do bearing shell with soft materials. 3. In sexual INA bearings of universal joint 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 elastic-plastic deformation compensation INA universal joint friction initial appearance 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, they all corrosion data INA universal joint bearing, thus, INA universal joint 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. Compressive strength of INA bearings of universal joint acceptance of one-way load without being crushed or size can not change. Don't let check bearing INA bearings of universal joint 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 INA universal joint 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.
